|
|
|
|
* 11.4.0: release
|
|
|
|
2023-05-20 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* From M. Holger: add QPDF::newReserved as a better alternative to
|
|
QPDFObjectHandle::newReserved. The operation of creating a new
|
|
reserved object fits better in the QPDF API. The old call just
|
|
delegates to the new one.
|
|
|
|
2023-05-13 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* When an annotation dictionary's appearance dictionary (`/AP`)
|
|
has a key that is a stream, disregard `/AS` (which is supposed to
|
|
point to a subkey). This enables qpdf to not ignore annotations
|
|
that have incorrect values for `/AS` when the appearance stream is
|
|
directly in the `/AP` dictionary instead of in a subkey. Fixes
|
|
#949.
|
|
|
|
2023-04-02 Jay Berkenbilt <ejb@ql.org>
|
|
* Allow QPDFJob's workflow to be split into a reading phase and a
|
|
writing phase to allow the caller to operate on the QPDF object
|
|
before it is written. This adds methods QPDFJob::createQPDF and
|
|
QPDFJob::writeQPDF and corresponding C API functions
|
|
qpdfjob_create_qpdf and qpdfjob_write_qpdf. Thanks to M. Holger
|
|
for the contribution.
|
|
|
|
2023-04-01 Jay Berkenbilt <ejb@ql.org>
|
|
* From M. Holger: throw a logic error if an uninitialized or
|
|
foreign QPDFObjectHandle is added to an array.
|
|
|
|
2023-03-18 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Enhance --optimize-images to support images nested inside of
|
|
form XObjects. Thanks to Connor Osborne (github user cdosborn) for
|
|
the contribution. Fixes #923.
|
|
|
|
2023-02-25 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* 11.3.0: release
|
|
|
|
* When performing overlay or underlay operations, convert the
|
|
original page to a form XObject instead of simply isolating its
|
|
contents with q/Q operators. This prevents unbalanced q/Q
|
|
operators in any of the original pages from messing up the
|
|
graphics state of anything that is overlaid on top of it. Fixes
|
|
#904.
|
|
|
|
2023-02-18 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Treat all linearization errors and warnings as warnings, and
|
|
issue them through the normal warning system using the new error
|
|
code qpdf_e_linearization. That means that --no-warn will suppress
|
|
them, and the file name is included in the warning. Fixes #851.
|
|
|
|
2023-01-28 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* New option --remove-restrictions removes security restrictions
|
|
from digitally signed files. Fixes #833.
|
|
|
|
2023-01-09 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Bug fix: flatten annotations should handle a page with no
|
|
/Resources key. Fixes #827.
|
|
|
|
2022-11-20 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* 11.2.0: release
|
|
|
|
* Add a few convenience methods to QPDFTokenizer::Token for
|
|
checking token types. thanks to M. Holger for the contribution.
|
|
|
|
* Add stream creation methods to the QPDF class as a better
|
|
alternative to the ones in the QPDFObjectHandle class. Thanks to
|
|
M. Holger for the contribution.
|
|
|
|
2022-11-19 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Bug fix: handle special case of an earlier xref stream object's
|
|
object number being reused by an update made by appending the
|
|
file. Fixes #809.
|
|
|
|
2022-10-08 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Fix major performance bug with the openssl crypto provider when
|
|
using OpenSSL 3. The legacy loader and rc4 algorithm was being
|
|
loaded with every call to the crypto provider instead of once in
|
|
the life of the program. Fixes #798.
|
|
|
|
* performance_check: add --test option to limit which tests are
|
|
run.
|
|
|
|
2022-10-06 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Change minimum required C++ version from C++-14 to C++-17.
|
|
|
|
* Fix another symbol export issue with the MinGW build.
|
|
|
|
2022-10-01 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* 11.1.1: release
|
|
|
|
2022-09-27 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Bug fix: avoid having the AppImage discard the first argument
|
|
when renamed to one of the embedded executables. Fixes #789.
|
|
|
|
* Add AppImage-specific tests to CI. These test different
|
|
invocation styles and loading of the proper shared library.
|
|
|
|
2022-09-26 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Bug fix: avoid using PDF Doc encoding for strings whose PDF Doc
|
|
encoding representation starts with UTF-16 or UTF-8 markers. Fixes
|
|
#778.
|
|
|
|
2022-09-27 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Add tests to CI for char being unsigned by default.
|
|
|
|
2022-09-14 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* 11.1.0: release
|
|
|
|
* Add notes to documentation clarifying that installing the dev
|
|
component usually requires the lib component to also be installed.
|
|
|
|
* Set CMAKE_INCLUDE_DIRECTORIES_PROJECT_BEFORE ON in cmake to
|
|
(hopefully) solve the problem of older installed qpdf headers
|
|
interfering with building qpdf from source. Fixes #763.
|
|
|
|
2022-09-12 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Add some missing DLL exports that only affect the Windows build.
|
|
|
|
* Remove compile-time test for LL_FMT. It's unlikely that any
|
|
compiler new enough to build qpdf still doesn't support %lld.
|
|
|
|
2022-09-10 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* 11.0.0: release
|
|
|
|
2022-09-09 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Add QPDFObjectHandle::isSameObjectAs to test whether two
|
|
QPDFObjectHandle objects point to the same underlying object.
|
|
|
|
* Expose ability to create custom loggers and to get and set the
|
|
logger for QPDF and QPDFJob through the C API.
|
|
|
|
2022-09-08 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Added new functions to the C API to support qpdf JSON:
|
|
qpdf_create_from_json_file, qpdf_create_from_json_data,
|
|
qpdf_update_from_json_file, qpdf_update_from_json_data, and
|
|
qpdf_write_json. Examples can be found in qpdf-ctest.c (in the
|
|
source tree), tests 42 through 47.
|
|
|
|
* Add QPDFObjectHandle::isDestroyed() to test whether an indirect
|
|
object was from a QPDF that has been destroyed.
|
|
|
|
2022-09-07 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Add QPDFObjectHandle::getQPDF(), which returns a reference, as
|
|
an alternative to QPDFObjectHandle::getOwningQPDF().
|
|
|
|
2022-09-06 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* For all bounding box methods in QPDFPageObjectHelper other than
|
|
MediaBox, add a parameter `copy_if_fallback`, and add comments
|
|
explaining in depth exactly what copy_if_shared and
|
|
copy_if_fallback mean. Fixes #664.
|
|
|
|
* Add new methods getArtBox and getBleedBox to
|
|
QPDFPageObjectHelper, completing the set of bounding box methods.
|
|
|
|
* The --show-encryption option now works even if a correct
|
|
password is not supplied. If you were using --show-encryption to
|
|
test whether you have the right password, use --requires-password
|
|
instead. Fixes #598.
|
|
|
|
2022-09-05 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Add a move constructor to Buffer, making it possible to move
|
|
rather than copy the internal buffer. Thanks to jbarlow83 for the
|
|
contribution.
|
|
|
|
2022-09-02 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Add new QPDF::create() factory method that returns
|
|
std::shared_ptr<QPDF>.
|
|
|
|
* Prevent copying/assigning to QPDF objects in the API. It has
|
|
never been safe to do this, but the API wasn't preventing it.
|
|
|
|
2022-09-01 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Remove QPDFObject.hh from include/qpdf. The only reason to
|
|
include was to get QPDFObject::object_type_e. Instead, include
|
|
qpdf/Constants.h, and change `QPDFObject::ot_` to `::ot_`.
|
|
|
|
* More optimizations and cleanup from m-holger (#726, #730)
|
|
including major refactor of QPDF's internal representations of
|
|
objects. In addition to a large performance improvement, this also
|
|
made it possible for QPDFObjectHandle::getOwningQPDF() to return a
|
|
null pointer if the owning QPDF had been destroyed. (A more
|
|
complete solution to this problem will be introduced for qpdf 12.)
|
|
This work also paves the way for a future alternative to
|
|
QPDFObjectHandle that is more idiomatic C++ and has greater type
|
|
safety.
|
|
|
|
2022-08-31 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* From m-holger (#729): refactor QPDF's parser into a new
|
|
QPDFParser class, cleaning the code, significantly improving
|
|
performance.
|
|
|
|
2022-08-27 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* From m-holger: major refactoring of QPDFTokenizer to improve
|
|
readability and to optimize performance. This also included some
|
|
optimizations to some InputSource classes. Thanks for this
|
|
excellent contribution. Fixes #749, #442.
|
|
|
|
2022-08-07 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Add new build configuration option ENABLE_QTC, which is off by
|
|
default when not running in MAINTAINER_MODE. When this is off,
|
|
QTC coverage calls sprinkled throughout the qpdf source code are
|
|
compiled out for increased performance. See "Build Options" in the
|
|
manual for a discussion. Fixes #714.
|
|
|
|
2022-08-06 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Added by m-holger: QPDF::getObject() method as a simpler form of
|
|
getObjectByID or getObjectByObjGen. The older methods are being
|
|
retained for compatibility and are not deprecated.
|
|
|
|
2022-07-24 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* include/qpdf/JSON.hh: Schema validation: allow a single item to
|
|
appear anywhere that the schema has an array of a single item.
|
|
This makes it possible to change an element of the schema from an
|
|
item to an array to allow the data to accept an array where a
|
|
single value was previously required. This change is needed to
|
|
allow QPDFJob JSON to start accepting multiple items where a
|
|
single item used to be expected without breaking backward
|
|
compatibility. Without this change, the earlier fix to
|
|
removeAttachment would be a breaking change. Also allow the schema
|
|
to contain a multi-element array, which means that the output has
|
|
to have an array of the same length in the corresponding location,
|
|
and each element is validated against the corresponding schema
|
|
element.
|
|
|
|
* QPDFObjectHandle: for the methods insertItem, appendItem,
|
|
eraseItem, replaceKey, and removeKey, add a corresponding
|
|
"AndGetNew" and/or "AndGetOld" methods. The ones that end with
|
|
"AndGetNew" return the newly added item. The ones that end with
|
|
"AndGetOld" return the old value. The AndGetNew methods make it
|
|
possible to create a new object, add it to an array or dictionary,
|
|
and get a handle to it all in one line. The AndGetOld methods make
|
|
it easier to retrieve an old value when removing or replacing it.
|
|
|
|
* Thanks to m-holger for doing significant cleanup of private APIs
|
|
and internals around QPDFObjGen and for significantly improving
|
|
the performance of QPDFObjGen -- See #731. This includes a few
|
|
user-visible changes:
|
|
- Addition of QPDFObjectHandle::StreamDataProvider::provideStreamData
|
|
overloads that take QPDFObjGen
|
|
- Addition of an optional argument to QPDFObjGen::unparse allowing
|
|
specification of a separator character, with the default
|
|
resulting in the old behavior
|
|
Examples have been updated to use improved APIs. The old
|
|
provideStreamData overloads will continue to be supported, so
|
|
updating older code to use the new interfaces is entirely at the
|
|
programmer's discretion.
|
|
|
|
2022-06-25 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Add tracking methods QPDF::everCalledGetAllPages() and
|
|
QPDF::everPushedInheritedAttributesToPages(). Since those methods
|
|
may have the side effect of creating new objects and replace
|
|
objects in various places in the pages tree, it's useful to be
|
|
able to find out whether they've ever been called.
|
|
|
|
2022-06-18 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Add QPDFJob::registerProgressReporter, making it possible to
|
|
override the progress reporter that is used when --progress (or
|
|
the equivalent) is configured with QPDFJob. This is
|
|
qpdfjob_register_progress_reporter in the C API.
|
|
|
|
* Add examples that show how to capture QPDFJob's output by
|
|
configuring the default logger (qpdfjob-save-attachment.cc,
|
|
qpdfjob-c-save-attachment.c). Fixes #691.
|
|
|
|
* Add C API for QPDFLogger -- see qpdflogger-c.h
|
|
|
|
* Add additional qpdfjob C API functions take a handle.
|
|
|
|
* Add qpdf_exit_code_e to Constants.h so that exit codes from
|
|
QPDFJob are accessible to the C API.
|
|
|
|
* When --progress or --verbose is combined with writing to
|
|
standard output, progress reporting and verbose messages go to
|
|
standard error. Previously it was disabled in this case.
|
|
|
|
2022-06-05 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* QPDFJob: API breaking change: QPDFJob::doIfVerbose passes a
|
|
Pipeline& rather than a std::ostream& to the the callback
|
|
function.
|
|
|
|
* Add integer types to pipeline's operator<<: short, int, long,
|
|
long long, unsigned short, unsigned int, unsigned long, unsigned
|
|
long long.
|
|
|
|
2022-05-30 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* qpdf JSON is now at version 2. New command-line arguments:
|
|
--json-output, --json-input, --update-from-json. New methods
|
|
QPDF::writeJSON, QPDF::createFromJSON, QPDF::updateFromJSON. For
|
|
details, see the "qpdf JSON" chapter of the manual.
|
|
|
|
* When showing encryption data in json output, when the user
|
|
password was recovered with by the owner password and the
|
|
specified password does not match the user password, reveal the
|
|
user password. This is not possible with 256-bit keys.
|
|
|
|
* Include additional information in --list-attachments --verbose
|
|
and in --json --json-key=attachments.
|
|
|
|
* Add QUtil::qpdf_time_to_iso8601 and QUtil::pdf_time_to_iso8601
|
|
for converting PDF/qpdf timestamps to ISO-8601 date format.
|
|
|
|
2022-05-18 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Add QUtil::FileCloser to the public API. This is a simple inline
|
|
class to help with automatic file closing.
|
|
|
|
2022-05-17 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Allow passing *uninitialized* (not null) objects to
|
|
replaceStreamData as filter and/or decode_parms to leave any
|
|
existing values for /Filter and /DecodeParms untouched.
|
|
|
|
2022-05-15 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Add QUtil::is_long_long to test whether a string can be
|
|
converted to a long long and back without loss of information.
|
|
|
|
2022-05-04 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* JSON: add a new "blob" type that takes a function to write data
|
|
into. The blob is serialized as a base64-encoded representation of
|
|
whatever is written to the function.
|
|
|
|
* FileInputSource has new constructors that eliminate the need to
|
|
call setFilename or setFile in most cases.
|
|
|
|
* Enhance JSON by adding a write method that takes a Pipeline* and
|
|
depth, and add several helper methods to make it easier to write
|
|
large amounts of JSON incrementally without having to have the
|
|
whole thing in memory.
|
|
|
|
* json v1 output: make "pages" and "objects" consistent.
|
|
Previously, "objects" always reflected the objects exactly as they
|
|
appeared in the original file, while "pages" reflected objects
|
|
after repair of the pages tree. This could be misleading. Now, if
|
|
"pages" is specified, "objects" shows the effects of repairing the
|
|
page tree, and if not, it doesn't. This makes no difference for
|
|
correct PDF files that don't have problems in the pages tree. JSON
|
|
v2 will behave in a similar way.
|
|
|
|
2022-05-03 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Add new Pipeline class Pl_String which appends to a std::string&
|
|
passed to it at construction.
|
|
|
|
* Add new Pipeline class Pl_OStream, similar to Pl_StdioFile but
|
|
takes a std::ostream instead of a FILE*.
|
|
|
|
* Add new convenience methods to Pipeline: writeCStr and
|
|
writeString. Also add a limit << operator that takes C strings and
|
|
std::strings. Also add an overloaded version of write that takes
|
|
"char const*".
|
|
|
|
* API change: Pipeline::write now takes "unsigned char const *"
|
|
instead of "unsigned char*". Callers shouldn't have to change
|
|
anything, though can stop using writable strings or
|
|
QUtil::unsigned_char_pointer. If you have implemented your own
|
|
pipelines, you should change your write method to take a const
|
|
pointer.
|
|
|
|
2022-05-01 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* JSON: add reactors to the JSON parser, making it possible to
|
|
react to JSON parsing events as they occur and to block the
|
|
results from being stored. This makes it possible to incrementally
|
|
parse arbitrarily large JSON inputs.
|
|
|
|
2022-04-30 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* QPDFWriter: change encryption API calls
|
|
- Remove deprecated versions of setR*EncryptionParameters
|
|
methods from before qpdf 8.4.0
|
|
- Replace setR2EncryptionParameters with
|
|
setR2EncryptionParametersInsecure
|
|
- Replace setR3EncryptionParameters with
|
|
setR3EncryptionParametersInsecure
|
|
- Replace setR4EncryptionParameters with
|
|
setR4EncryptionParametersInsecure
|
|
|
|
* C API: change encryption API calls to match C++ interface
|
|
- Remove pre-8.4.0 functions:
|
|
- qpdf_set_r3_encryption_parameters
|
|
- qpdf_set_r4_encryption_parameters
|
|
- qpdf_set_r5_encryption_parameters
|
|
- qpdf_set_r6_encryption_parameters
|
|
- Add "_insecure" to insecure encryption triggers:
|
|
- Replace void qpdf_set_r2_encryption_parameters
|
|
with qpdf_set_r2_encryption_parameters_insecure
|
|
- Replace void qpdf_set_r3_encryption_parameters2
|
|
with qpdf_set_r3_encryption_parameters_insecure
|
|
- Replace void qpdf_set_r4_encryption_parameters2
|
|
with qpdf_set_r4_encryption_parameters_insecure
|
|
|
|
* Make attempting to write encrypted files that use RC4 (40-bit or
|
|
128-bit without AES) an error rather than a warning when
|
|
--allow-weak-crypto is not specified. Fixes #576.
|
|
|
|
2022-04-24 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Bug fix: "removeAttachment" in the job JSON now takes an array
|
|
of strings instead of a string. It should have taken an array of
|
|
strings since the corresponding command-line argument,
|
|
--remove-attachment, is repeatable. Fixes #693.
|
|
|
|
* Deprecate QPDFObjectHandle::replaceOrRemoveKey -- it does and
|
|
always has done the same thing as replaceKey.
|
|
|
|
2022-04-23 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Add a new QPDF::warn method that takes the parameters of
|
|
QPDFExc's constructor except for the filename, which is taken from
|
|
the QPDF object. This is a shorter way to issue warnings on behalf
|
|
of a QPDF object.
|
|
|
|
* Add new method QUtil::is_explicit_utf8 that tests whether a
|
|
string is explicitly marked as being UTF-8 encoded, as allowed by
|
|
the PDF 2.0 spec. Such a string starts with the bytes 0xEF 0xBB
|
|
0xBF, which is the UTF-8 encoding of U+FEFF.
|
|
|
|
* Add new method QUtil::get_next_utf8_codepoint as a low-level
|
|
helper for iterating through the UTF-8 characters in a byte
|
|
string.
|
|

|
|
|
|
* Breaking CLI change: the default value for --json is now
|
|
"latest" rather than "1". At this moment, "1" is the latest
|
|
version, but version "2" will be added before the release of
|
|
qpdf 11.
|
|
|
|
* Perform code cleanup including some source-compatible but not
|
|
binary compatible changes to function signatures, use of anonymous
|
|
namespaces, and use of "= default" and "= delete" in declarations.
|
|
|
|
2022-04-09 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Replace PointerHolder with std::shared_ptr through the QPDF API.
|
|
A backward-compatible interface is provided and enabled by default
|
|
with a warning that can be turned off. See "Smart Pointers" in the
|
|
"Design and Library Notes" section of the manual for information
|
|
including a detailed migration process to assist with migrating
|
|
code that uses the qpdf library.
|
|
|
|
2022-04-03 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Add automatic code formatting with clang-format. See "Code
|
|
Formatting" in the "Contributing to qpdf" chapter of the manual.
|
|
|
|
2022-03-19 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* 10.6.3.0cmake1: unofficial release
|
|
|
|
* Conversion of build system to cmake. This change doesn't include
|
|
any user-visible functional changes to the library API or CLI but
|
|
completely replaces the build system. Details can be found in the
|
|
manual in the "Building and Installing QPDF" and "Notes for
|
|
Packagers" sections, especially "Converting From autoconf to
|
|
cmake" in "Building and Installing QPDF". Highlights of the
|
|
changes can be found in the release notes.
|
|
|
|
2022-03-08 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* 10.6.3: release
|
|
|
|
* Use Windows 2022 github runners and therefore Visual Studio 2022
|
|
to create Windows distributions
|
|
|
|
* Fix DLL export issue with mingw (Windows)
|
|
|
|
2022-03-07 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Minor internal changes to assist with building in other
|
|
environments: rename internal bits.icc to qpdf/bits_functions.hh
|
|
(not part of public API), enforce reordering of header files to
|
|
prevent jpeglib.h from interfering with other headers, remove an
|
|
unused header that was accidentally added in 10.6.0 but never
|
|
referenced by any code.
|
|
|
|
* Make build work and tests work when NDEBUG is defined. This
|
|
involved a few changes to some test files but no changes to any
|
|
library code.
|
|
|
|
2022-02-25 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Bug fix in JSON parser: accept \/ in a string as valid input per
|
|
JSON spec even though we don't translate / to \/ on output.
|
|
|
|
2022-02-22 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Recognize PDF strings explicitly marked as UTF-8 as allowed by
|
|
the PDF 2.0 spec. Fixes #654.
|
|
|
|
2022-02-18 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Bug fix: when generating appearance streams, the font size was
|
|
substituted incorrectly from /DA if Tf was absent or the number
|
|
preceding Tf was out of range. Fixes #655.
|
|
|
|
2022-02-16 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* 10.6.2: release
|
|
|
|
2022-02-15 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Fix asymmetrical logic between
|
|
QPDFObjectHandle::newUnicodeString() and
|
|
QPDFObjectHandle::getUTF8Val(). The asymmetrical logic didn't
|
|
matter before fixing the PDF Doc transcoding bugs.
|
|
|
|
* When analyzing PDF strings, recognize UTF-16LE as UTF-16. The
|
|
PDF spec only allows UTF-16BE, but most readers seem to allow
|
|
both. Fixes #649.
|
|
|
|
* Bug fix: 10.6.0 inadvertently removed an unknown/undocumented
|
|
CLI parsing feature, which has been restored in 10.6.2. Fixes #652.
|
|
|
|
* Don't map 0x18 through 0x1f, 0x7f, 0x9f, or 0xad as fixed points
|
|
when transcoding UTF-8 to PDFDoc. These code points have different
|
|
meanings in those two encoding systems. Fixes #650.
|
|
|
|
2022-02-11 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* 10.6.1: release
|
|
|
|
* Fix some compilation issues from use of abs without including
|
|
proper headers.
|
|
|
|
2022-02-09 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* 10.6.0: release
|
|
|
|
* Fix one more PDF doc encoding omission: 0xAD is also undefined.
|
|
Fixes #637.
|
|
|
|
2022-02-08 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Bug fix: when splitting pages with --split-pages or selecting
|
|
pages with --pages, set the output PDF version to the maximum of
|
|
all the input PDF versions. This is a fix to QPDFJob. If you are
|
|
creating output PDF files yourself from multiple inputs, you will
|
|
need to code the same thing. The new PDFVersion object, its
|
|
updateIfGreater() method, and the new QPDF and QPDFWriter methods
|
|
described below make this very easy to do. Fixes #610.
|
|
|
|
* Add new class PDFVersion for more convenient comparison of PDF
|
|
version numbers from the %!PDF header.
|
|
|
|
* Add QPDF::getVersionAsPDFVersion() to return the PDF version and
|
|
extension together as a PDFVersion object instead of a string.
|
|
|
|
* Add a QPDFWriter::setMinimumPDFVersion() that takes a PDFVersion
|
|
object.
|
|
|
|
2022-02-06 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Pl_Buffer and QPDFWriter: add getBufferSharedPointer(), which
|
|
turns a PointerHolder<Buffer> but will return a
|
|
std::shared_ptr<Buffer> in qpdf 11.
|
|
|
|
* From m-holger: add getKeyIfDict(), which calls getKey for
|
|
dictionaries and returns null if called on null. This is for
|
|
easier access to optional, lower-level dictionaries.
|
|
|
|
2022-02-05 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Add several new accessors to QPDFObjectHandle: the bool
|
|
getValueAsX(X&) accessors allow an alternative way to retrieve
|
|
values from QPDFObjectHandle objects and can result in more
|
|
concise code in many situations. Thanks to m-holger for the
|
|
contribution.
|
|
|
|
* Add qpdf_oh_new_binary_unicode_string and
|
|
qpdf_oh_get_binary_utf8_value to the C API. This makes it possible
|
|
to handle UTF-8-encoded strings with embedded NUL characters. Thanks
|
|
to m-holger for the contribution.
|
|
|
|
* Add a global user-defined string literal "_qpdf" as a shorthand
|
|
for QPDFObjectHandle::parse, allowing you to create
|
|
QPDFObjectHandle objects with
|
|
|
|
QPDFObjectHandle oh = "<</Some (PDF)>>"_qpdf;
|
|
|
|
* Expose QPDF::emptyPDF to the C API as qpdf_empty_pdf()
|
|
|
|
* Add comments letting people know that the version string
|
|
returned by QPDF::QPDFVersion and qpdf_get_qpdf_version is static.
|
|
|
|
* Add QUtil::make_unique_cstr to return a std::unique_ptr<char[]>
|
|
as an alternative to QUtil::copy_string and
|
|
QUtil::make_shared_cstr.
|
|
|
|
2022-02-04 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* New preprocessor symbols QPDF_MAJOR_VERSION, QPDF_MINOR_VERSION,
|
|
QPDF_PATCH_VERSION as numbers and QPDF_VERSION as a string. These
|
|
can be used for feature testing in code. These are in qpdf/DLL.h,
|
|
which is included by every header that adds to the public API.
|
|
Since these constants are introduced in version 10.6, it's
|
|
important for them to be in a header that everyone already
|
|
includes so you don't have to try to include a header that won't
|
|
be there.
|
|
|
|
* PointerHolder: add a get() method and a use_count() method for
|
|
compatibility with std::shared_ptr. In qpdf 11, qpdf's APIs will
|
|
switch to using std::shared_ptr instead of PointerHolder, though
|
|
there will be a PointerHolder class with a backward-compatible
|
|
API. To ease the transition, we are adding get() now with the same
|
|
semantics as std::shared_ptr's get. Note that there is a
|
|
difference in behavior: const PointerHolder has always behaved
|
|
incorrectly. const PointerHolder objects only returned const
|
|
pointers. This is wrong. If you want a const pointer, use
|
|
PointerHolder<T const>. A const PointerHolder just shouldn't allow
|
|
its pointer to be reassigned. The new get() method behaves
|
|
correctly in that calling get() on a const PointerHolder to a
|
|
non-const pointer returns a non-const pointer. This is the way
|
|
regular pointers behave.
|
|
|
|
2022-02-01 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Major refactor: all functionality from the qpdf CLI is now
|
|
available for library users using the QPDFJob class. See comments
|
|
in include/qpdf/QPDFJob.hh and a new chapter about QPDFJob in the
|
|
manual. QPDFJob provides fluent interfaces for setting options
|
|
that exactly map to command-line arguments. There are also methods
|
|
for initializing QPDFJob from an argv array and from a JSON
|
|
object.
|
|
|
|
* A light C API around basic QPDFJob functionality is in
|
|
include/qpdf/qpdfjob-c.h.p
|
|
|
|
* Add new functions version of QUtil::call_main_from_wmain that
|
|
takes a constant argv array.
|
|
|
|
2022-01-31 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Have --json-help just output the JSON object, leaving a
|
|
description to --help and the manual.
|
|
|
|
* The --json flag now takes a version number as an optional
|
|
parameter. The default will remain version 1 for compatibility
|
|
until the release of qpdf 11, after which it will become "latest".
|
|
At this time, there's only version 1, but a version 2 may appear
|
|
in a future qpdf.
|
|
|
|
2022-01-28 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Add QPDFUsage exception, which is thrown by QPDFJob to indicate
|
|
command-line usage or job configuration errors.
|
|
|
|
2022-01-22 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Add QUtil::make_shared_cstr to return a std::shared_ptr<char>
|
|
instead of a char* like QUtil::copy_string
|
|
|
|
* JSON: for (qpdf-specific, not official) "schema" checking, add
|
|
the ability to treat missing fields as optional. Also ensure that
|
|
values in the schema are dictionary, array, or string.
|
|
|
|
* Add convenience methods isNameAndEquals and isDictionaryOfType
|
|
to QPDFObjectHandle with corresponding functions added to the C
|
|
API. Thanks to m-holger for the contribution.
|
|
|
|
2022-01-17 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Add JSON::parse. Now qpdf's JSON class implements a
|
|
general-purpose JSON parser and serializer, but there are better
|
|
options for general use. This is really designed for qpdf's
|
|
internal use and is set up to be compatible with qpdf's existing
|
|
API and to hook into a planned JSON-based API to the QPDFJob
|
|
class.
|
|
|
|
* Add isDictionary and isArray to JSON
|
|
|
|
2022-01-11 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Major overhaul of documentation and help for the qpdf
|
|
command-line tool. qpdf --help is now broken into topics rather
|
|
than being one great wall of text, and the command-line arguments
|
|
are indexed in the manual. The entire text of the "Running qpdf"
|
|
chapter has been reviewed thoroughly. Many thanks once again to
|
|
M. Holger for a detailed review and editorial assistance with the
|
|
manual.
|
|
|
|
* Bug fix: add missing characters from PDF doc encoding.
|
|
Fixes #606.
|
|
|
|
2021-12-29 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Add method QUtil::file_can_be_opened
|
|
|
|
2021-12-21 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* 10.5.0: release
|
|
|
|
* Add documentation link to top-level README
|
|
|
|
* Discontinue inclusion of the pre-built documentation in the
|
|
source distribution. Consult the packaging documentation in the
|
|
manual for details. The file README-doc.txt is installed in the
|
|
doc directory by default and contains information that users will
|
|
need to know to find the documentation.
|
|
|
|
2021-12-19 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* C API: clarify documentation around string lengths. Add two new
|
|
methods: qpdf_oh_get_binary_string_value and
|
|
qpdf_oh_new_binary_string to make the need to handle the length
|
|
and data separate in more explicit in cases in which the string
|
|
data may contain embedded null characters.
|
|
|
|
2021-12-17 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* C API: simplify error handling for uncaught errors (never in a
|
|
released version) and clarify documentation in qpdf-c.h around
|
|
error handling. See qpdf-c.h for details, including how to check
|
|
for errors and the new function qpdf_silence_errors.
|
|
|
|
* C API: expose getTypeCode and getTypeName from QPDFObjectHandle.
|
|
Fixes #597.
|
|
|
|
* C API: add functions for working with stream data. Search for
|
|
"STREAM FUNCTIONS" in qpdf-c.h. Fixes #596.
|
|
|
|
* QPDFObjectHandle object types have been moved from
|
|
QPDFObject::object_type_e to qpdf_object_type_e (defined in
|
|
Constants.h). Old values are available for backward compatibility.
|
|
|
|
* Add Pl_Buffer::getMallocBuffer() to initialize a buffer with
|
|
malloc in support of the C API
|
|
|
|
2021-12-16 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Add several functions to the C API for working with pages. C
|
|
wrappers around several of the "Legacy" page operations from
|
|
QPDFObjectHandle.hh have been added. See "PAGE FUNCTIONS" in
|
|
qpdf-c.h for details. Fixes #594.
|
|
|
|
2021-12-12 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Convert documentation from docbook to reStructuredText/Sphinx.
|
|
|
|
2021-12-10 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Handle bitstream overflow errors more gracefully. Fixes #581.
|
|
|
|
* C API: add qpdf_get_object_by_id, qpdf_make_indirect_object, and
|
|
qpdf_replace_object, exposing the corresponding methods in QPDF
|
|
and QPDFObjectHandle. Fixes #588.
|
|
|
|
* Add missing QPDF_DLL to QPDFObjectHandle::addTokenFilter so that
|
|
it is actually accessible as part of the public interface as
|
|
intended. Fixes #580.
|
|
|
|
* C API: Overhaul how errors are handle the C API's object handle
|
|
interfaces. Clarify documentation regarding object accessors and
|
|
how type errors and warnings are handled. Many cases that used to
|
|
crash code that used the C API can now be trapped and will be
|
|
written stderr if not trapped. See qpdf-c.h for details.
|
|
|
|
* C API: Add qpdf_oh_new_uninitialized to explicitly create
|
|
uninitialized object handles.
|
|
|
|
* Add new error code qpdf_e_object that is used for exceptions
|
|
(including warnings) that are caused by using QPDFObjectHandle
|
|
methods on object handles of the wrong type.
|
|
|
|
2021-12-02 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* C API: Add qpdf_oh_is_initialized.
|
|
|
|
* C API: Add qpdf_get_last_string_length to return the length of
|
|
the last string returned. This is necessary in order to fully
|
|
retrieve values of strings that may contain embedded null characters.
|
|
|
|
* C API: Add qpdf_oh_new_object to clone an object handle. Change
|
|
implemented by m-holger in #587.
|
|
|
|
2021-11-16 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* 10.4.0: release
|
|
|
|
2021-11-10 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Add --allow-weak-crypto option to suppress warnings about use of
|
|
weak cryptographic algorithms. Update documentation around this
|
|
issue. Fixes #358.
|
|
|
|
2021-11-07 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Relax xref recovery logic a bit so that files whose objects are
|
|
either missing endobj or have endobj at other than the beginning
|
|
of a line can still be recovered. Fixes #573.
|
|
|
|
2021-11-04 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Add support for OpenSSL 3. Fixes #568.
|
|
|
|
The OpenSSL version is detected at compile-time. If you want to
|
|
build with OpenSSL 3 on a system that has OpenSSL 1 installed, you
|
|
can run configure like this (or similar to this depending on how
|
|
you installed openssl3):
|
|
|
|
pc_openssl_CFLAGS=-I/path/to/openssl3/include \
|
|
pc_openssl_LIBS='-L/path/to/openssl3/lib64 -lssl -lcrypto' \
|
|
./configure
|
|
|
|
where /path/to/openssl3 is wherever your OpenSSL 3 distribution is
|
|
installed. You may also need to set the LD_LIBRARY_PATH
|
|
environment variable if it's not installed in a standard location.
|
|
|
|
* Add range check in QPDFNumberTreeObjectHelper (fuzz issue 37740).
|
|
|
|
* Add QIntC::range_check_subtract to do range checking on
|
|
subtraction, which has different boundary conditions from
|
|
addition.
|
|
|
|
* Bug fix: fix crash that could occur under certain conditions
|
|
when using --pages with files that had form fields. Fixes #548.
|
|
|
|
* Add an extra check to the library to detect when foreign objects
|
|
are inserted directly (instead of using
|
|
<function>QPDF::copyForeignObject</function>) at the time of
|
|
insertion rather than when the file is written. Catching the error
|
|
sooner makes it much easier to locate the incorrect code.
|
|
|
|
2021-11-03 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Bug fix: make overlay/underlay work on a page with no resource
|
|
dictionary. Fixes #527.
|
|
|
|
2021-11-02 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Add QPDF::findPage to the public API. This is primarily to help
|
|
improve the efficiency of code that wraps the qpdf library, such
|
|
as pikepdf. Fixes #516.
|
|
|
|
* zlib-flate: warn and exit with code 3 when there is corrupted
|
|
input data even when decompression is possible. We do this in the
|
|
zlib-flate CLI so that it can be more reliably used to test the
|
|
validity of zlib streams, but we don't warn by default in qpdf
|
|
itself because PDF files in the wild exist with this problem and
|
|
other readers appear to tolerate it. There is a PDF in the qpdf
|
|
test suite (form-filled-by-acrobat.pdf) that was written by a
|
|
version of Adobe Acrobat that exhibits this problem. Fixes #562.
|
|
|
|
* Add Pl_Flate::setWarnCallback to make it possible to be notified
|
|
of data errors that are recoverable but still indicate invalid
|
|
data.
|
|
|
|
* Improve error reporting when someone forgets the -- after
|
|
--pages. Fixes #555.
|
|
|
|
2021-05-12 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Bug fix: ensure we don't overflow any string bounds while
|
|
handling completion, even when we are given bogus input values.
|
|
Fixes #441.
|
|
|
|
2021-05-09 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Improve performance of preservation of object streams by
|
|
avoiding unnecessary traversal of objects when there are no object
|
|
streams.
|
|
|
|
2021-05-08 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* 10.3.2: release
|
|
|
|
* Fix problem that caused the generated manual from being included
|
|
in the Windows distributions. Fixes #521.
|
|
|
|
* Fix 11-year-old bug of leaving unreferenced objects in preserved
|
|
object streams. Fixes #520.
|
|
|
|
2021-04-17 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Portability fix: use tm_gmtoff rather than global timezone
|
|
variable if available to get timezone offset. This fixes
|
|
compilation on BSD and also results in a daylight saving
|
|
time-aware offset for Linux or other GNU systems. Fixes #515.
|
|
|
|
2021-04-05 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* When adding a page, if the page already exists, make a shallow
|
|
copy of the page instead of throwing an exception. This makes the
|
|
behavior of adding a page from the library consistent with what
|
|
the CLI does and also with what the library does if it starts with
|
|
a file that already has a duplicated page. Note that this means
|
|
that, in some cases, the page you pass to addPage or addPageAt
|
|
(either in QPDF or QPDFPageDocumentHelper) will not be the same
|
|
object that actually gets added. (This has actually always been
|
|
the case.) That means that, if you are going to do subsequent
|

|
|
|
|
* 10.3.1: release
|
|
|
|
* Bug fix: allow /DR to be direct in /AcroForm
|
|
|
|
2021-03-04 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* 10.3.0: release
|
|
|
|
* The last several changes are in support of fixing more complex
|
|
cases of keeping form fields working properly through page copying
|
|
operations. Fixes #509.
|
|
|
|
* Deprecated QPDFAcroFormDocumentHelper::copyFieldsFromForeignPage
|
|
-- use QPDFAcroFormDocumentHelper::fixCopiedAnnotations instead.
|
|
The API for dealing with annotations and form fields around
|
|
copying pages is extremely complex and very hard to get right. It
|
|
is planned for a future version of qpdf to have a higher level
|
|
interface for dealing with copying pages around and preserving
|
|
document-level constructs.
|
|
|
|
* Add QPDFAcroFormDocumentHelper::getFieldsWithQualifiedName for
|
|
returning a list of fields by name.
|
|
|
|
* Add QPDFAcroFormDocumentHelper::addAndRenameFormFields to add a
|
|
collection of fields while ensuring that, within the collection,
|
|
fields with the same name continue to have the same name, but that
|
|
they don't conflict with exiting fields in the document.
|
|
|
|
* Add QPDFAcroFormDocumentHelper::setFormFieldName for changing
|
|
the name of a form field in a manner that preserves
|
|
QPDFAcroFormDocumentHelper's cache.
|
|
|
|
2021-03-03 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Handle /DR properly when copying form fields. This is a
|
|
significant rework of the form field copying from 10.2.0. It
|
|
ensures that when copy fields from different files, we resolve any
|
|
conflicting names in resources.
|
|
|
|
* Add QPDFMatrix::operator==
|
|
|
|
* Add QPDFObjectHandle::makeResourcesIndirect
|
|
|
|
2021-03-02 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Add an optional resource_names argument to getUniqueResourceName
|
|
for added efficiency.
|
|
|
|
* Add conflict detection QPDFObjectHandle::mergeResources.
|
|
|
|
2021-03-01 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Improve code that finds unreferenced resources to ignore names
|
|
in the content stream that are not fonts or XObjects. This should
|
|
reduce the number of cases when qpdf needlessly decides not to
|
|
remove unreferenced resources. Hopefully it doesn't create any new
|
|
bugs where it removes unreferenced resources that it isn't
|
|
supposed to.
|
|
|
|
* Add QPDF::numWarnings() -- useful to tell whether any warnings
|
|
were issued by a specific bit of code.
|
|
|
|
2021-02-26 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Bug fix: QPDFFormFieldObjectHelper was mis-handling /DA, /Q, and
|
|
/DR in ways that usually didn't matter but were still wrong. /DA
|
|
and /Q were being found in the field hierarchy, but if not found,
|
|
the default values in the /AcroForm dictionary were not being
|
|
used. /DR was being treated as an inherited field in the field
|
|
dictionary, which is wrong. It is actually supposed to come from
|
|
the /AcroForm dictionary. We were getting away with this since
|
|
many popular form writers seem to copy it to the field as well,
|
|
even though the spec makes no mention of doing this. To support
|
|
this, QPDFFormFieldObjectHelper::getDefaultResources was added.
|
|
|
|
2021-02-25 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Update StreamDataProvider examples to use copyStream() when they
|
|
want to get to the original stream data from the provider. Prior
|
|
to 10.2.0, we had to copy the stream to another QPDF, but now we
|
|
can just use copyStream().
|
|
|
|
* Bug fix/behavior change: when QPDF::replaceObject or
|
|
QPDF::swapObjects is called, existing QPDFObjectHandle instances
|
|
will now notice the change. This removes a long-standing source of
|
|
bugs and confusing behavior.
|
|
|
|
2021-02-23 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* 10.2.0: release
|
|
|
|
* The test for the input and output files being the same wasn't
|
|
implemented correctly for --split-pages since the specified output
|
|
file is really a pattern, not the actual output file.
|
|
|
|
2021-02-22 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* From qpdf CLI, --pages and --split-pages will properly preserve
|
|
interactive form functionality. Fixes #340.
|
|
|
|
* Add QPDFAcroFormDocumentHelper::copyFieldsFromForeignPage to
|
|
copy form fields from a foreign page into the current file. (This
|
|
method didn't work and was deprecated in 10.3.0.)
|
|
|
|
* Add QPDFFormFieldObjectHelper::getTopLevelField to get the
|
|
top-level field for a given form field.
|
|
|
|
* Update pdf-overlay-page example to include copying of
|
|
annotations.
|
|
|
|
* Add a new version of QPDFPageObjectHelper::placeFormXObject that
|
|
initializes the transformation matrix that was used so you don't
|
|
have to call both placeFormXObject and
|
|
getMatrixForFormXObjectPlacement.
|
|
|
|
2021-02-21 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* From qpdf CLI, --overlay and --underlay will copy annotations
|
|
and form fields from overlay/underlay file. Fixes #395.
|
|
|
|
* Add QPDFPageObjectHelper::copyAnnotations, which copies
|
|
annotations and, if applicable, associated form fields, from one
|
|
page to another, possibly transforming the rectangles.
|
|
|
|
* Bug fix: --flatten-rotation now applies the required
|
|
transformation to annotations on the page.
|
|
|
|
* Add QPDFAcroFormDocumentHelper::transformAnnotations to apply a
|
|
transformation to a group of annotations.
|
|
|
|
* Add QPDFObjGen::unparse()
|
|
|
|
* Add QPDFObjectHandle::copyStream() for making a copy of a stream
|
|
within the same QPDF instance.
|
|
|
|
* Allow QPDFObjectHandle::newArray and
|
|
QPDFObjectHandle::newFromMatrix take QPDFMatrix as well as
|
|
QPDFObjectHandle::Matrix
|
|
|
|
* Make member variables a--f of QPDFMatrix public
|
|
|
|
2021-02-20 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Allow --rotate=0 to clear rotation from a page.
|
|
|
|
2021-02-18 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Add QPDFAcroFormDocumentHelper::addFormField, which adds a new
|
|
form field, initializing the AcroForm dictionary if needed.
|
|
|
|
* Add QPDFPageObjectHelper::getMatrixForFormXObjectPlacement,
|
|
which returns the transformation matrix required to map from a
|
|
form field's coordinate system into a specific rectangle within
|
|
the page.
|
|
|
|
* Add QUtil::path_basename to get last element of a path.
|
|
|
|
* Add examples/pdf-attach-file.cc to illustrate new file
|
|
attachment method and also new parse that takes indirect objects.
|
|
|
|
2021-02-17 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Allow optional numeric argument to --collate. If --collate=n is
|
|
given, pull n pages from the first file, n pages from the second
|
|
file, etc., until we run out of pages.
|
|
|
|
2021-02-15 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Add a version of QPDFObjectHandle::parse that takes a QPDF* as
|
|
context so that it can parse strings containing indirect object
|
|
references.
|
|
|
|
2021-02-14 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Add new versions of QPDFObjectHandle::replaceStreamData that
|
|
take std::function objects for cases when you need something
|
|
between a static string and a full-fledged StreamDataProvider.
|
|
Using this with QUtil::file_provider is a very easy way to create
|
|
a stream from the contents of a file.
|
|
|
|
2021-02-12 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Move formerly internal QPDFMatrix class to the public API. This
|
|
class provides convenience methods for working with transformation
|
|
matrices.
|
|
|
|
* QUtil::double_to_string: trim trailing zeroes by default, and
|
|
add option to not trim trailing zeroes. This causes a syntactic
|
|
but semantically preserving change in output when doubles are
|
|
converted to strings. The library uses double_to_string in only a
|
|
few places. In practice, output will be different (trailing zeroes
|
|
removed) in code that creates form XObjects (mostly generation of
|
|
appearance streams for form fields as well as overlay and
|
|
underlay) and in the flatten rotation code that was added in qpdf
|
|
10.1.
|
|
|
|
2021-02-10 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Require a C++-14 compiler.
|
|
|
|
* Detect loops when adding when reading outlines dictionary upon
|
|
initialization of QPDFOutlineDocumentHelper (fuzz issue 30507).
|
|
|
|
* Add "attachments" as an additional json key, and add some
|
|
information about attachments to the json output.
|
|
|
|
* Add new command-line arguments for operating on attachments:
|
|
--list-attachments, --add-attachment, --remove-attachment,
|
|
--copy-attachments-from. See --help and manual for details.
|
|
|
|
2021-02-09 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Add methods to QUtil for working with PDF timestamp strings:
|
|
pdf_time_to_qpdf_time, qpdf_time_to_pdf_time,
|
|
get_current_qpdf_time.
|
|
|
|
2021-02-08 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Add helper classes for file attachments:
|
|
QPDFEmbeddedFileDocumentHelper, QPDFFileSpecObjectHelper,
|
|
QPDFEFStreamObjectHelper. See their header files for details.
|
|
|
|
2021-02-07 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Add new functions QUtil::pipe_file and QUtil::file_provider for
|
|
sending the contents of a file through a pipeline as binary data.
|
|
|
|
2021-02-04 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Add new option --password-file=file for reading the decryption
|
|
password from a file. file may be "-" to read from standard input.
|
|
Fixes #499.
|
|
|
|
* By default, give an error if a user attempts to encrypt a file
|
|
with a 256-bit key, a non-empty user password, and an empty owner
|
|
password. Such files are insecure since they can be opened with no
|
|
password. To allow explicit creation of files like this, pass the
|
|
new --allow-insecure option. Thanks to github user RobK88 for a
|
|
detailed analysis and for reporting this issue. Fixes #501.
|
|
|
|
2021-02-02 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Bug fix: if a form XObject lacks a resources dictionary,
|
|
consider any names in that form XObject to be referenced from the
|
|
containing page. This is compliant with older PDF versions. Also
|
|
detect if any form XObjects have any unresolved names and, if so,
|
|
don't remove unreferenced resources from them or from the page
|
|
that contains them. Fixes #494.
|
|
|
|
2021-01-31 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Bug fix: properly handle strings if they appear in inline image
|
|
dictionaries while externalizing inline images.
|
|
|
|
2021-01-30 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Add examples/pdf-name-number-tree.cc to illustrate new
|
|
name/number tree API and new array/dictionary iterator API.
|
|
|
|
2021-01-29 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Add methods to QPDFObjectHandle that provide a C++ iterator API,
|
|
including C++11 range-for iteration, over arrays and dictionaries.
|
|
With this, you can do
|
|
|
|
for (auto i: dict_oh.ditems())
|
|
{
|
|
// i.first is a string, i.second is a QPDFObjectHandle
|
|
}
|
|
for (auto i: array_oh.aitems())
|
|
{
|
|
// i is a QPDFObjectHandle
|
|
}
|
|
|
|
* QPDFObjectHandle::is* methods to check type now return false on
|
|
uninitialized objects rather than crashing or throwing a logic
|
|
error.
|
|
|
|
2021-01-24 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Implement remove for name and number trees as well as exposing
|
|
remove and insertAfter methods for iterators. With this addition,
|
|
qpdf now has robust read/write support for name and number trees.
|
|
|
|
2021-01-23 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Add an insert method to QPDFNameTreeObjectHelper and
|
|
QPDFNumberTreeObjectHelper.
|
|
|
|
* QPDFNameTreeObjectHelper and QPDFNumberTreeObjectHelper will
|
|
automatically repair broken name and number trees by default. This
|
|
behavior can be turned off.
|
|
|
|
* Change behavior of QPDFObjectHandle::newUnicodeString so that it
|
|
encodes ASCII or PDFDocEncoding if those encodings will support
|
|
all the characters in the string, resorting to UTF-16 only if the
|
|
other encodings are insufficient. This is a cleaner implementation
|
|
of the intention of encoding strings for use outside of contents
|
|
and results in fewer instances of ASCII strings being needlessly
|
|
encoded as UTF-16. This change may cause qpdf to generate
|
|
different output from the same input when form field values are
|
|
set using methods from QPDFFormFieldObjectHelper.
|
|
|
|
2021-01-16 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Add new constructors for QPDFNameTreeObjectHelper and
|
|
QPDFNumberTreeObjectHelper that take a QPDF object so they can
|
|
create indirect objects and issue warnings. The old constructors
|
|
are deprecated and will be removed in qpdf 11. Just pass in the
|
|
owning QPDF of the object handle used to initialize the helpers.
|
|
|
|
* Re-implement QPDFNameTreeObjectHelper and
|
|
QPDFNumberTreeObjectHelper to be much more efficient and to have
|
|
an iterator-based API in addition to the existing one. This makes
|
|
it possible to use "range-for" loops over these helpers and to
|
|
iterate through name and number trees without creating a map
|
|
containing all the keys and values, which is slow and potentially
|
|
consumes a lot of memory.
|
|
|
|
* Add warn() to QPDF's public API.
|
|
|
|
2021-01-11 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Fix very old error in code that was finding attachment streams.
|
|
Probably this error never mattered, but the code was still not
|
|
exactly right.
|
|
|
|
2021-01-06 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Give warnings instead of segfaulting if a QPDF operation is
|
|
attempted after calling closeInputSource(). Fixes #495.
|
|
|
|
2021-01-05 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* 10.1.0: release
|
|
|
|
2021-01-04 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* When qpdf CLI extracts pages, it now only attempts to remove
|
|
unreferenced resources from the pages that it is keeping. This
|
|
change dramatically reduces the time it takes to extract a small
|
|
number of pages from a large, complex file.
|
|
|
|
* Move getNext()->write() calls in some pipelines to ensure that
|
|
state gates properly reset even if the next pipeline's write
|
|
throws an exception (fuzz issue 28262).
|
|
|
|
2021-01-03 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Don't include -o nospace with zsh completion setup so file
|
|
completion works normally. Fixes #473.
|
|
|
|
2021-01-02 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Make QPDFPageObjectHelper methods pipeContents, parseContents,
|
|
and addContentTokenFilter work with form XObjects.
|
|
|
|
* Rename some QPDFPageObjectHelper methods and make them support
|
|
form XObjects as well as pages. The old names will be preserved
|
|
from compatibility.
|
|
- pipePageContents -> pipeContents
|
|
- parsePageContents -> parseContents
|
|
|
|
* Add QPDFObjectHandle::parseAsContents to apply ParserCallbacks
|
|
to a form XObject.
|
|
|
|
* QPDFPageObjectHelper::externalizeInlineImages can be called with
|
|
form XObjects as well as pages.
|
|
|
|
* Bug fix: QPDFPageObjectHelper::externalizeInlineImages was not
|
|
descending into form XObjects on a page. It now does this by
|
|
default. In the extremely unlikely event that anyone was actually
|
|
depending on the old behavior, it is available by passing
|
|
shallow=true to the externalizeInlineImages call.
|
|
|
|
* Bug fix: QPDFObjectHandle::filterPageContents was broken for
|
|
pages with an array of content streams. This caused
|
|
externalize-inline-images to also be broken for this case.
|
|
|
|
2021-01-01 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Add methods to QPDFPageObjectHelper: forEachXObject,
|
|
forEachImage, forEachFormXObject to call a function on each
|
|
XObject (or image or form XObject) in a page or form XObject,
|
|
possibly recursing into nested form XObjects.
|
|
|
|
* Add method QPDFPageObjectHelper::getFormXObjects to return a map
|
|
of keys to form XObjects (non-recursively) from a page or form
|
|
XObject.
|
|
|
|
* Add method QPDFObjectHandle::isImage to test whether an object
|
|
is an image.
|
|
|
|
2020-12-31 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* QPDFPageObjectHelper::removeUnreferencedResources can now be
|
|
called with a QPDFPageObjectHelper created from a form XObject.
|
|
The method already recursed into form XObjects.
|
|
|
|
* Rename some QPDFPageObjectHelper methods and make them support
|
|
form XObjects as well as pages. The old names will be preserved
|
|
from compatibility.
|
|
- getPageImages -> getImages
|
|
- filterPageContents -> filterContents
|
|
|
|
* Add QPDFObjectHandle::isFormXObject to test whether an object is
|
|
a form XObject.
|
|
|
|
2020-12-30 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Add QPDFPageObjectHelper::flattenRotation and --flatten-rotation
|
|
option to the qpdf CLI. The flattenRotation method removes any
|
|
/Rotate key from a page dictionary and implements the same
|
|
rotation by modifying the page's contents such that the various
|
|
page boxes are altered and the page renders identically. This can
|
|
be used to work around buggy PDF applications that don't properly
|
|
handle page rotation. The --flatten-rotation option to the qpdf
|
|
CLI calls flattenRotation for every page.
|
|
|
|
2020-12-26 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Add QPDFObjectHandle::setFilterOnWrite, which can be used to
|
|
tell QPDFWriter not to filter a stream on output even if it can.
|
|
You can use this to prevent QPDFWriter from touching a stream
|
|
(either uncompressing or compressing) that you have optimized or
|
|
otherwise ensured looks exactly the way you want it, even if
|
|
decode level or stream compression would otherwise cause
|
|
QPDFWriter to modify the stream.
|
|
|
|
* Add ostream << for QPDFObjGen. (Don't ask why it took 7.5 years
|
|
for me to decide to do this.)
|
|
|
|
2020-12-25 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Refactor write code to eliminate an extra full traversal of
|
|
objects in the file and to remove assumptions that preclude stream
|
|
references from appearing in /DecodeParms of filterable streams.
|
|
This results in an approximately 8% performance reduction in write
|
|
times.
|
|
|
|
2020-12-23 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Allow library users to provide their own decoders for stream
|
|
filters by deriving classes from QPDFStreamFilter and registering
|
|
them using QPDF::registerStreamFilter. Registered stream filters
|
|
provide code to validate and interpret /DecodeParms for a specific
|
|
/Filter and also to provide a pipeline that will decode. Note that
|
|
it is possible to encode to a filter type that is not supported
|
|
even without this feature. See examples/pdf-custom-filter.cc for
|
|
an example of using custom stream filters.
|
|
|
|
2020-12-22 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Add QPDFObjectHandle::makeDirect(bool allow_streams) -- if
|
|
allow_streams is true, preserve indirect references to streams
|
|
rather than throwing an exception. This allows the object to be
|
|
made as direct as possible while preserving stream references.
|
|
|
|
2020-12-20 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Add qpdf_register_progress_reporter method to C API,
|
|
corresponding to QPDFWriter::registerProgressReporter. Fixes #487.
|
|
|
|
2020-11-28 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Add new functions to the C API for manipulating
|
|
QPDFObjectHandles. The new functions allow creation and
|
|
modification of objects, which brings a lot of additional power to
|
|
the C API. See include/qpdf/qpdf-c.h for details and
|
|
examples/pdf-c-objects.c for a simple example.
|
|
|
|
2020-11-21 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* 10.0.4: release
|
|
|
|
* Fix QIntC::range_check to handle negative numbers properly (fuzz
|
|
issue 26994).
|
|
|

* Treat a direct page object as a runtime error rather than a
|
|
logic error since it is actually possible to create a file that
|
|
has this (fuzz issue 27393).
|
|
|
|
2020-11-09 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Handle "." appearing in --pages not preceded by a numeric range
|
|
as a special case in command-line parsing code.
|
|
|
|
2020-11-04 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Ignore the value of the offset/generation field in an xref entry
|
|
for a deleted object. Also attempt file recovery on lower-level
|
|
exceptions thrown while reading the xref table. Fixes #482.
|
|
|
|
2020-10-31 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* 10.0.3: release
|
|
|
|
* Don't enter extension initialization in QPDFWriter on a direct
|
|
object. Fixes stack overflow in pathological case of /Root being a
|
|
direct object (fuzz issue 26761).
|
|
|
|
* My previous fix to #449 (handling foreign streams with indirect
|
|
objects in /Filter and/or /DecodeParms) was incorrect and caused
|
|
other problems. There is a now a correct fix to the original
|
|
problem. Fixes #478.
|
|
|
|
2020-10-27 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* 10.0.2: release
|
|
|
|
2020-10-25 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* When signing distribution files, generate sha256 checksums
|
|
instead of md5, sha1, and sha512. sha256 seems to be more widely
|
|
used, and there's no reason to use md5 or sha1 anymore.
|
|
|
|
* Official Windows releases are now built using the openssl crypto
|
|
provider. The native provider is still available for selection at
|
|
runtime using the QPDF_CRYPTO_PROVIDER environment variable.
|
|
|
|
* Bug fix: --no-warn was not suppressing some warnings that might
|
|
be generated by --split-pages.
|
|
|
|
2020-10-23 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Bug fix: when concatenating content streams, insert a newline if
|
|
needed to prevent the last token from the old stream from being
|
|
merged with the first token of the new stream. Qpdf was mistakenly
|
|
concatenating the streams without regard to the specification that
|
|
content streams are to be broken on token boundaries. Fixes #444.
|
|
|
|
* fix-qdf: handle empty streams better with ignore newline by
|
|
treating them as empty even though, technically, a blank line
|
|
would be required inside the Stream. This just makes it easier to
|
|
add place-holder empty streams while editing qdf files by hand.
|
|
|
|
2020-10-22 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Fix memory leak that could occur if objects in object streams
|
|
were resolved more than once and the objects within the object
|
|
streams contained circular references. This leak could be
|
|
triggered when qpdf was run with --object-streams=generate on
|
|
files that already had object streams containing circular
|
|
references (fuzz issue 23642).
|
|
|
|
* Add QIntC::range_check for checking to see whether adding two
|
|
numbers together will cause an overflow.
|
|
|
|
* Fix loop detection problem when traversing page thumbnails
|
|
during optimization (fuzz issue 23172).
|
|
|
|
2020-10-21 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Bug fix: properly handle copying foreign streams that have
|
|
indirect /Filter or /DecodeParms keys when stream data has been
|
|
replaced. The circumstances leading to this bug are very unusual
|
|
but would cause qpdf to either generate an internal error or some
|
|
other kind of warning situation if it would occur. Fixes #449.
|
|
|
|
* Qpdf's build and CI has been migrated from Azure Pipelines
|
|
(Azure DevOps) to GitHub Actions.
|
|
|
|
* Remove some fuzz files that triggered Mal/PDFEx-H with some
|
|
virus scanners. There's plenty of coverage in the fuzz corpus
|
|
without these files, and it's a nuisance to have virus checkers
|
|
remove them. Fixes #460.
|
|
|
|
* Ensure that numeric conversion is not affected by the user's
|
|
global locale setting. Fixes #459.
|
|
|
|
* Add qpdf-<version>-linux-x86_64.zip to the list of built
|
|
distributions. This is a simple zip file that contains just the
|
|
qpdf executables and the dependent shared libraries that would not
|
|
ordinarily be present on a base system. This minimal binary
|
|
distribution works as is when used as a Lambda layer in AWS and
|
|
could be suitable for inclusion in a docker image or other
|
|
standalone Linux/x86_64 environment where you want minimal support
|
|
for running the qpdf executable. Fixes #352.
|
|
|
|
2020-10-20 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Add --warning-exit-0 option to the qpdf command line. When
|
|
specified, qpdf will exit with a status of 0 rather than 3 when
|
|
there are warnings without errors. Combine with --no-warn to
|
|
completely ignore warnings.
|
|
|
|
* Bug fix: fix further cases in which errors were written to
|
|
stdout. Fixes #438.
|
|
|
|
* Build option: add --disable-rpath option to ./configure, which
|
|
disables passing -rpath to the linker when building shared
|
|
libraries with libtool. Fixes #422.
|
|
|
|
2020-10-16 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Accept pull request that improves how the Windows native crypto
|
|
provider is obtained.
|
|
|
|
* Accept pull request that improves performance in processing
|
|
files in memory.
|
|
|
|
* Accept pull requests that improve openssl configuration and
|
|
error reporting.
|
|
|
|
* Build using GitHub Actions. The intention is that this will
|
|
replace Azure Pipelines as the official CI for qpdf for the next
|
|
release.
|
|
|
|
2020-10-15 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Make many minor improvements to the build process and code
|
|
health, including fixing a lgtm warning and compiler warnings from
|
|
newer version of gcc and MSVC toolchains. Add several cosmetic
|
|
improvements to build output in CI.
|
|
|
|
* Added LL_FMT to config.h.in. This is populated automatically by
|
|
autoconf, but if build with your own build system, you may need to
|
|
define it as whatever the format string needed by printf for long
|
|
long is. Usually this is "%lld", but it can be "%I64d" for some
|
|
older Windows-based compilers.
|
|
|
|
2020-04-29 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Bug fix: qpdf --check was writing errors and warnings reported
|
|
by checkLinearization to stdout instead of stderr. Fixes #438.
|
|
|
|
2020-04-09 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* 10.0.1: release
|
|
|
|
2020-04-08 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Bug fix: qpdf 10.0.0 introduced a bug in which
|
|
QPDFObjectHandle::getStreamData would return the raw data when
|
|
called on an unfilterable stream instead of throwing an exception
|
|
like it's supposed to. Fixes #425.
|
|
|
|
2020-04-07 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Improve pdf-invert-images example to show a pattern of copying
|
|
streams into another QPDF object to enable a stream data provider
|
|
to access the original stream data.
|
|
|
|
* Fix error that caused a compilation error with clang. Fixes
|
|
#424.
|
|
|
|
2020-04-06 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* 10.0.0: release
|
|
|
|
* Move random number generation into the crypto providers. The old
|
|
os-based secure random number generation with fallback to insecure
|
|
random number generation (only if allowed at build time) has moved
|
|
into the native crypto provider. If using other providers
|
|
(currently gnutls or openssl), random number generation will use
|
|
those libraries. The old interfaces for supplying your own random
|
|
number generator are still in place. Fixes #418.
|
|
|
|
* Source-level incompatibility: remove QUtil::srandom. There was
|
|
no reason to ever call this, and it didn't do anything unless
|
|
insecure random number generation was compiled in, which it is not
|
|
by default. If you were calling this, just remove the call because
|
|
it wasn't doing anything anyway.
|
|
|
|
* Add openssl crypto provider, contributed by Dean Scarff. This
|
|
provider is implemented using OpenSSL and also works with
|
|
BoringSSL.
|
|
|
|
2020-04-04 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Add a new provideStreamData method for StreamDataProvider that
|
|
allows a success code to be returned and that accepts the
|
|
suppress_warnings and will_retry methods. This makes it possible
|
|
to have a StreamDataProvider call pipeStreamData and propagate its
|
|
results back. This change allows better error handling and
|
|
recovery when objects are copied from other files and when
|
|
"immediate copy from" is enabled.
|
|
|
|
* When copying foreign streams, the same type of recovery from
|
|
streams with filtering errors is performed as when dealing with
|
|
streams in the original input. This could happen, for example, if
|
|
you are using the --pages option to take pages from another file
|
|
and that file has errors in it.
|
|
|
|
* Add a new version of QPDFObjectHandle::pipeStreamData whose
|
|
return value indicates overall success or failure rather than
|
|
whether nor not filtering was attempted. It should have always
|
|
been this way. This change was done in a backward-compatible
|
|
fashion. Previously existing pipeStreamData methods' return values
|
|
mean the same as always.
|
|
|
|
* Add "objectinfo" section to json output. In this release,
|
|
information about whether each object is a stream or not is
|
|
provided. There's otherwise no way to tell conclusively from the
|
|
json output. Over time, other computed information about objects
|
|
may be added here.
|
|
|
|
* Add new option --remove-unreferenced-resources that takes auto,
|
|
yes, or no as options. This tells qpdf whether to attempt to
|
|
remove unreferenced resources from pages when doing page splitting
|
|
operations. Prior to this change, the default was to attempt to
|
|
remove unreferenced resources, but this operation was very slow,
|
|
especially for large and complex files. The new default is "auto",
|
|
which tells qpdf to analyze the file for shared resources. This is
|
|
a relatively quick test. If no shared resources are found, then we
|
|
don't attempt to remove unreferenced resources, because
|
|
unreferenced resources never occur in files without shared
|
|
resources. To force qpdf to look for and remove unreferenced
|
|
resources, use --remove-unreferenced-resources=yes. The option
|
|
--preserve-unreferenced-resources is now a synonym for
|
|
--remove-unreferenced-resources=no.
|
|
|
|
* Use std::atomic for unique ID generation internally within the
|
|
library. This eliminates the already extremely low chance of a
|
|
collision, improves thread safety, and removes a dependency on a
|
|
random number generator. Thanks to Dean Scarff for the
|
|
contribution.
|
|
|
|
2020-04-03 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Allow qpdf to be built on systems without wchar_t. All "normal"
|
|
systems have wchar_t because it is part of the C++ standard, but
|
|
there are some stripped down environments that don't have it. See
|
|
README.md (search for wchar_t) for instructions and a discussion.
|
|
Fixes #406.
|
|
|
|
* Add two extra optional arguments to
|
|
QPDFPageObjectHelper::placeFormXObject to control whether the
|
|
placed item is allowed to be shrunk or expanded to fit within or
|
|
maximally fill the destination rectangle. Prior to this change,
|
|
placeFormXObject might shrink it but would never expand it.
|
|
|
|
* When calling the C API, accept any non-zero value as TRUE rather
|
|
than just 1. This appears to resolve issues on Windows when
|
|
calling some versions of the DLL directly from other languages.
|
|
|
|
2020-04-02 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Add method QPDFObjectHandle::unsafeShallowCopy for copying only
|
|
top-level dictionary keys or array items. See comments in
|
|
QPDFObjectHandle.hh for when this should be used.
|
|
|
|
* Remove Members class indirection for QPDFObjectHandle. Those are
|
|
copied and assigned too often, and that change caused a very
|
|
substantial performance hit.
|
|
|
|
2020-03-31 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* When detecting unreferenced images during page splitting, if any
|
|
XObjects are form XObjects, recursively descend into them and
|
|
remove any unreferenced objects from them too. Fixes #373.
|
|
|
|
* Add QPDFObjectHandle::filterAsContents, which filters a stream's
|
|
data as if it were page contents. This can be useful to filter
|
|
form XObjects the same way we would filter page contents.
|
|
|
|
* If QPDF_EXECUTABLE is set, use it as the path to qpdf for
|
|
purposes of completion. This variable is only read during the
|
|
execution of `qpdf --completion-zsh` and `qpdf
|
|
--completion-bash`. It is not used during the actual evaluation of
|
|
completions.
|
|
|
|
2020-02-22 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Update pdf-set-form-values.cc to use and mention
|
|
generateAppearance, which hadn't been added when the example was
|
|
originally created.
|
|
|
|
* Detect, warn, and correct the case of /Pages in the document
|
|
catalog incorrectly pointing to a page or intermediate node
|
|
instead of the root of the pages tree. Fixes #398.
|
|
|
|
2020-01-26 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* 9.1.1: release
|
|
|
|
* Bug fix: in qdf mode, do not write out any XRef streams that may
|
|
have appeared in the original file. These are usually
|
|
unreferenced, but with --preserve-unreferenced, they could be
|
|
written out, which breaks fix-qdf's assumption that there is at
|
|
most one XRef stream and that it appears at the end of the file.
|
|
Fixes #386.
|
|
|
|
* Bug fix: when externalizing inline images, a colorspace value
|
|
that was a lookup key in the page's /Resource -> /ColorSpace
|
|
dictionary was not properly handled. Fixes #392.
|
|
|
|
* Add "encrypt" key to the json output. This contains largely the
|
|
same information as given by --show-encryption but in a
|
|
consistent, parseable format.
|
|
|
|
* Add options --is-encrypted and --requires-password. These can be
|
|
used with files, including encrypted files with unknown passwords,
|
|
to determine whether or not a file is encrypted and whether a
|
|
password is required to open the file. The --requires-password
|
|
option can also be used to determine whether a supplied password
|
|
is correct. Information is supplied through exit codes, making
|
|
these options particularly useful for shell scripts. Fixes #390.
|
|
|
|
2020-01-14 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Fix for Windows being unable to acquire crypt context with a new
|
|
keyset. Thanks to Cloudmersive for the fix. Fixes #387.
|
|
|
|
* Rewrite fix-qdf in C++. This means fix-qdf is a proper
|
|
executable now, and there is no longer a runtime requirement on
|
|
perl.
|
|
|
|
* Add QUtil::call_main_from_wmain, a helper function that can be
|
|
called in the body of wmain to convert UTF-16 arguments to UTF-8
|
|
arguments and then call another main function.
|
|
|
|
2020-01-13 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* QUtil::read_lines_from_file: add new versions that use FILE*,
|
|
use FILE* instead if std::ifstream internally to support correct
|
|
handling of Unicode filenames in Windows, and add the option to
|
|
preserve line endings.
|
|
|
|
2019-11-17 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* 9.1.0: release
|
|
|
|
* This is the first version of qpdf that requires C++-11.
|
|
|
|
2019-11-09 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* 9.1.rc1: release
|
|
|
|
* Improve behavior of wildcard expansion for msvc executable when
|
|
run from the Windows cmd.exe shell. Unlike in UNIX environments,
|
|
Windows leaves it up to the executable to expand its own
|
|
wildcards. Fixes #224.
|
|
|
|
* Allow :even or :odd to be appended to numeric ranges for
|
|
--pages, --rotate, and other options that take page ranges.
|
|
|
|
* When reading /P from the encryption dictionary, use static_cast
|
|
instead of QIntC to convert the value to a signed integer. The
|
|
value of /P is a bit field, and PDF files have been found in the
|
|
wild where /P is represented as an unsigned integer even though
|
|
the spec states that it is a signed 32-bit value. By using
|
|
static_cast, we allow qpdf to compensate for writers that
|
|
incorrectly represent the correct bit field as an unsigned value.
|
|
Fixes #382.
|
|
|
|
2019-11-05 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Add support for pluggable crypto providers, enabling multiple
|
|
implementations of the cryptographic functions needed by qpdf.
|
|
This feature was added by request of Red Hat, which recognized the
|
|
use of qpdf's native crypto implementations as a potential
|
|
security liability, preferring instead to get all crypto
|
|
functionality from a third-party library that receives a lot of
|
|
scrutiny. However it was also important to me to not impose any
|
|
unnecessary third party dependencies on my users or packagers,
|
|
some of which build qpdf for lots of environments, some of which
|
|
may not easily support gnutls. Starting in qpdf 9.1.0, it is be
|
|
possible to build qpdf with both the native and gnutls crypto
|
|
providers or with either in isolation. In support of this feature,
|
|
new classes QPDFCryptoProvider and QPDFCryptoImpl have been added
|
|
to the public interface. See QPDFCryptoImpl.hh for details about
|
|
adding your own crypto provider and QPDFCryptoProvider.hh for
|
|
details about choosing which one is used. Note that selection of
|
|
crypto providers is invisible to anyone who doesn't explicitly
|
|
care. Neither end users nor developers have to be concerned about
|
|
it.
|
|
|
|
* The environment variable QPDF_CRYPTO_PROVIDER can be used to
|
|
override qpdf's default choice of crypto provider. The
|
|
--show-crypto flag to the qpdf CLI can be used to present a list
|
|
of supported crypto providers with the default provider always
|
|
listed first.
|
|
|
|
* Add gnutls crypto provider. Thanks to Zdenek Dohnal for
|
|
contributing the code that I ultimately used in the gnutls crypto
|
|
provider and for engaging in an extended discussion about this
|
|
feature. Fixes #218.
|
|
|
|
2019-10-22 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Incorporate changes from Masamichi Hosoda <trueroad@trueroad.jp>
|
|
to properly handle signature in the following ways:
|
|
- Always represent /Contents in a signature dictionary as a hex
|
|
string
|
|
- Do not compress signature dictionaries when generating object
|
|
streams
|
|
- Do not encrypt/decrypt the /Contents field of the signature
|
|
dictionary when creating or reading encrypted files
|
|
|
|
* Incorporate changes from Masamichi Hosoda <trueroad@trueroad.jp>
|
|
to add additional methods for making it possible to gain deeper
|
|
insight into cross reference tables and object renumbering. These
|
|
new API calls make it possible for applications to go into PDF
|
|
files created by qpdf and make changes to them that go beyond
|
|
working with the PDF at the object level. The specific use case
|
|
for these changes was to write an external tool to perform digital
|
|
signature, but there could be other uses as well. New methods
|
|
include the following, all of which are described in their
|
|
respective headers:
|
|
- QPDF::getXRefTable()
|
|
- QPDFObjectHandle::getParsedOffset()
|
|
- QPDFWriter::getRenumberedObjGen(QPDFObjGen)
|
|
- QPDFWriter::getWrittenXRefTable()
|
|
|
|
2019-10-12 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* 9.0.2: release
|
|
|
|
* Change the name of the temporary file used by --replace-input to
|
|
work with arbitrary absolute or relative paths without requiring
|
|
path splitting logic. Fixes #365.
|
|
|
|
2019-09-20 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* 9.0.1: release
|
|
|
|
2019-09-19 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* When converting an array to a Rectangle, ensure that llx <= urx
|
|
and lly <= ury. This prevents flatten-annotations from flipping
|
|
fields whose coordinates are messed up in the input. Fixes #363.
|
|
|
|
* Warn when duplicated dictionary keys are found during parsing.
|
|
The behavior remains as before: later keys override earlier ones.
|
|
However, this generates a warning now rather than being silently
|
|
ignored. Fixes #345.
|
|
|
|
2019-09-17 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Fix a few integer warnings for big-endian systems.
|
|
|
|
* QIntC tests: don't assume char is signed. Fixes #361.
|
|
|
|
2019-08-31 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* 9.0.0: release
|
|
|
|
* Add QPDF::anyWarnings() method to find out whether there have
|
|
been any warnings without resetting the list.
|
|
|
|
* Add QPDF::closeInputSource() method to release the input source
|
|
so the input file can be deleted or renamed.
|
|
|
|
* Add methods rename_file and remove_file to QUtil.
|
|
|
|
2019-08-24 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Add QPDF::userPasswordMatched() and QPDF::ownerPasswordMatched()
|
|
methods so it can be determined separately whether the supplied
|
|
password matched the user password, the owner password, or both.
|
|
Fixes #159.
|
|

|
|
|
|
* Add --recompress-streams option to qpdf and
|
|
QPDFWriter::setRecompressFlate to cause QPDFWriter to recompress
|
|
streams that are already compressed with /FlateDecode.
|
|
|
|
* Add option Pl_Flate::setCompressionLevel to globally set the
|
|
zlib compression level used by all Pl_Flate pipelines.
|
|
|
|
* Add --compression-level flag to qpdf to set the zlib compression
|
|
level. When combined with --recompress-flate, this will cause most
|
|
of qpdf's streams to use the maximum compression level. This
|
|
results in only a very small amount of savings in size that comes
|
|
at a fairly significant performance cost, but it could be useful
|
|
for archival files or other cases where every byte counts and
|
|
creation time doesn't matter so much. Note that using
|
|
--object-streams=generate in combination with these options gives
|
|
you the biggest advantage. Fixes #113.
|
|

|
|
|
|
* In QPDFObjectHandle::ParserCallbacks, in addition to
|
|
handleObject(QPDFObjectHandle), allow developers to override
|
|
handleObject(QPDFObjectHandle, size_t offset, size_t length). If
|
|
this method appears instead, it is called with the offset of the
|
|
object in the content stream (which may be concatenated from an
|
|
array of streams) and the length of the object. Intervening
|
|
whitespace and comments are not included in offset and length.
|
|
|
|
* Add method
|
|
QPDFObjectHandle::ParserCallbacks::contentSize(size_t). If
|
|
defined, it is called by the content stream parser before the
|
|
first call to handleObject, and the argument is the total size in
|
|
bytes of the content streams.
|
|
|
|
* Add QPDFObjectHandle::isDirectNull() -- a const method that
|
|
allows determining whether an object is a literal null without
|
|
attempting to resolve it.
|
|
|
|
* Stop replacing indirect references to null with literal null in
|
|
arrays when writing output with QPDFWriter.
|
|
|
|

|
|
|
|
* Accept (and warn for) extraneous whitespace preceding the xref
|
|
table. Fixes #341.
|
|
|
|
* Accept (and warn for) extraneous whitespace between the stream
|
|
keyword and newline. Fixes #329.
|
|
|
|
* Properly handle name tokens containing # not preceding two
|
|
hexadecimal digits. Such names are invalid in PDF >= 1.2 but valid
|
|
in PDF 1.0 and 1.1. Prior to this fix, qpdf's behavior was to
|
|
treat such tokens as an error for PDF >= 1.2, but for older PDF
|
|
tokens, the name was silently accepted, and when the name token
|
|
was written out, the # was changed to #23, which is the correct
|
|
way to represent a # character. This behavior was problematic for
|
|
several reasons: one is that, ordinarily, content streams are not
|
|
parsed, so this would cause things like image references whose
|
|
names contained # to break. Also, even if the input file was 1.0
|
|
or 1.1, there's no guarantee that the output file wouldn't be
|
|
written at a new version, resulting in invalid name tokens. The
|
|
new behavior is to issue a warning upon encountering such a token
|
|
but to accept it, regardless of the PDF version. Such tokens are
|
|
written out properly as well. Additionally, the warning message
|
|
indicates that the tokens are invalid for PDF >= 1.2. Fixes #332.
|
|
|
|
* Non-compatible API change: remove
|
|
QPDFTokenizer::allowPoundAnywhereInName(). There were a lot of
|
|
problems with this. When it was used, any name tokens read would
|
|
always be modified on output, which is never the correct behavior.
|
|
This method used to signal QPDFTokenizer to not treat # specially
|
|
in name tokens, which resulted in the incorrect behavior whose fix
|
|
is described in the preceding item.
|
|
|
|
2019-08-18 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* When traversing the pages tree, if an invalid /Type key is
|
|
encountered, fix it. This is not done for all operations, but it
|
|
will be done for any case in which getAllPages is called. This
|
|
includes all page-based CLI operations. (Hopefully) Fixes #349.
|
|
|
|
2019-08-17 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Change internal implementation of QPDF arrays to use sparse
|
|
arrays, which results in using much less memory for arrays with
|
|
large numbers of nulls. Various files have been encountered in the
|
|
wild that contains thousands of arrays with millions of nulls.
|
|
Fixes #305, #311.
|
|
|
|
2019-07-03 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Non-compatible API change: change
|
|
QPDFOutlineDocumentHelper::getTopLevelOutlines and
|
|
QPDFOutlineObjectHelper::getKids to return a std::vector instead
|
|
of a std::list of QPDFOutlineObjectHelper objects. This is to work
|
|
around bugs with some compilers' STL implementations that are
|
|
choking with list here. There's no deep reason for these to be
|
|
lists instead of vectors. Fixes #297.
|
|
|
|
2019-06-22 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Handle encrypted files with missing or invalid /Length entries
|
|
in the encryption dictionary.
|
|
|
|
* QPDFWriter: allow calling set*EncryptionParameters before
|
|
calling setFilename. Fixes #336.
|
|
|
|
* It now works to run --completion-bash and --completion-zsh when
|
|
qpdf is started from an AppImage.
|
|
|
|
* Provided a more useful error message when Windows can't get
|
|
security context. Thanks to user zdenop for supplying some code.
|
|
Fixes #286.
|
|
|
|
* Favor PointerHolder over manual memory allocation in shippable
|
|
code where possible. Fixes #235.
|
|
|
|
* If pkg-config is available, use it to local libjpeg and zlib. If
|
|
not, fall back to old behavior. Fixes #324.
|
|
|
|
* The "make install" target explicitly sets a mode rather than
|
|
relying the user's umask. Fixes #326.
|
|
|
|
* When a file has linearization warnings but no errors, qpdf
|
|
--check and --check-linearization now exit with code 3 instead
|
|
of 2. Fixes #50.
|
|
|
|
* Add new function QUtil::read_file_into_memory.
|
|
|
|
2019-06-21 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* When supported, qpdf builds with -fvisibility=hidden, which
|
|
removes non-exported symbols from the shared library in a manner
|
|
similar to how Windows DLLs work. This is better for performance
|
|
and also better for safety and protection of private interfaces.
|
|
See https://gcc.gnu.org/wiki/Visibility. *NOTE*: If you are
|
|
getting linker errors trying to catch exceptions or derive things
|
|
from a base class in the qpdf library, it's possible that a
|
|
QPDF_DLL_CLASS declaration is missing somewhere. Please report
|
|
this as a bug at https://github.com/qpdf/qpdf/issues.
|
|
|
|
* Source-level incompatibility: remove the version
|
|
QPDF::copyForeignObject with an unused boolean parameter. If you
|
|
were, for some reason, calling this, just take the parameter away.
|
|
|
|
* Source-level incompatibility: remove the version
|
|
QPDFTokenizer::expectInlineImage with no arguments. It didn't
|
|
produce correct inline images. This is a very low-level routine.
|
|
There is little reason to call it outside of qpdf's lexical
|
|
engine.
|
|
|
|
* Source-level incompatibility: rename QUtil::strcasecmp to
|
|
QUtil::str_compare_nocase. This is a non-compatible change, but
|
|
QUtil::strcasecmp is hardly the most important part of qpdf's API.
|
|
The reason for this change is that strcasecmp is a macro on some
|
|
systems, and that was causing problems when QUtil.hh was included
|
|
in certain circumstances. Fixes #242.
|
|
|
|
2019-06-20 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Enable compilation with additional warnings for integer
|
|
conversion and sign (-Wsign-conversion, -Wconversion for gcc and
|
|
similar; -W3 for msvc) if supported. These warnings are on by
|
|
default can be turned off by passing --disable-int-warnings
|
|
|
|
* Fix all integer sign and conversion warnings. This makes all
|
|
integer type conversions that have potential data loss explicit
|
|
with calls that do range checks and raise an exception.
|
|
|
|
* Change out_bufsize argument to Pl_Flate's constructor for int to
|
|
unsigned int for compatibility with underlying zlib
|
|
implementation.
|
|
|
|
* Change QPDFObjectHandle::pipeStreamData's encode_flags argument
|
|
from unsigned long to int since int is the underlying type of the
|
|
enumerated type values that are passed to it. This change should
|
|
be invisible to virtually all code unless you are compiling with
|
|
strict warning flags and explicitly casting to unsigned long.
|
|
|
|
* Add methods to QPDFObjectHandle to return the value of Integer
|
|
objects as int and unsigned int with range checking and fallback
|
|
behavior to avoid silent underflow/overflow conditions.
|
|
|
|
* Add functions to QUtil to convert unsigned integers to strings,
|
|
avoiding implicit conversion between unsigned and signed integer
|
|
types.
|
|
|
|
* Add QIntC.hh, containing integer type converters that do range
|
|
checking.
|
|
|
|
2019-06-18 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Remove previously submitted qpdf_read_memory_fuzzer as it is a
|
|
small subset of qpdf_fuzzer.
|
|
|
|
2019-06-15 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Update CI (Azure Pipelines) to run tests with some sanitizers.
|
|
|
|
* Do "ideal integration" with oss-fuzz. This includes adding a
|
|
better fuzzer with a seed corpus and adding automated tests of the
|
|
fuzzer with the test data.
|
|
|
|
* When parsing files, while reading an object, if there are too
|
|
many consecutive errors without enough intervening successes, give
|
|
up on the specific object. This reduces cases in which very badly
|
|
damaged files send qpdf into a tail spin reading one character at
|
|
a time and reporting warnings.
|
|
|
|
2019-06-13 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Perform initial integration of Google's oss-fuzz project by
|
|
copying the fuzzer someone from Google already did into the qpdf
|
|
repository and adding build support. This shift in control is in
|
|
preparation for an ideal integration with oss-fuzz.
|
|
|
|
2019-06-09 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* When /DecodeParms is an empty list, ignore it on read and delete
|
|
it on write. Fixes #331.
|
|
|
|

|
|
|
|
* 8.4.2: release
|
|
|
|
2019-05-16 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Fix memory error in Windows-only code from typo. Fixes #330.
|
|
|
|
2019-04-27 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* 8.4.1: release
|
|
|
|
2019-04-20 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* When qpdf --version is run, it will detect if the qpdf CLI was
|
|
built with a different version of qpdf than the library. This
|
|
usually indicates that multiple versions of qpdf are installed and
|
|
that the library path is not set up properly. This situation
|
|
sometimes causes confusing behavior for users who are not actually
|
|
running the version of qpdf they think they are running.
|
|
|
|
* Add parameter --remove-page-labels to remove page labels from
|
|
output. In qpdf 8.3.0, the behavior changed so that page labels
|
|
were preserved when merging and splitting files. Some users were
|
|
relying on the fact that if you ran qpdf --empty --pages ... all
|
|
page labels were dropped. This option makes it possible to get
|
|
that behavior if it is explicitly desired. Fixes #317.
|
|
|
|
* Add parameter --keep-files-open-threshold to override the
|
|
maximum number of files that qpdf will allow to be kept open at
|
|
once. Fixes #288.
|
|
|
|
* Handle Unicode characters in filenames properly on Windows. The
|
|
changes to support Unicode on the CLI in Windows broke Unicode
|
|
filenames on that platform. Fixes #298.
|
|
|
|
* Slightly tighten logic that determines whether an object is a
|
|
page. The previous logic was sometimes failing to preserve
|
|
annotations because they were passing the overly loose test for
|
|
whether something was a page. This fix has a slight risk of
|
|
causing some extraneous objects to be copied during page splitting
|
|
and merging for erroneous PDF files whose page objects contain
|
|
invalid types or are missing the /Type key entirely, both of which
|
|
would be invalid according to the PDF specification.
|
|
|
|
* Revert change that included preservation of outlines (bookmarks)
|
|
in --split-pages. The way it was implemented caused a very
|
|
significant performance penalty when splitting pages with
|
|
outlines. We need a better solution that only copies the relevant
|
|
items, not the whole tree.
|
|
|
|
2019-03-11 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* JSON serialization: add missing leading 0 to decimal values
|
|
between -1 and 1. Fixes #308.
|
|
|
|
2019-02-01 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* 8.4.0: release
|
|
|
|
2019-01-31 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Bug fix: do better pre-checks on images before optimizing;
|
|
refuse to optimize images that can't be converted to JPEG because
|
|
of colorspace or depth.
|
|
|
|
* Add new options --externalize-inline-images, which converts
|
|
inline images larger than a specified size to regular images, and
|
|
--ii-min-bytes, which tweaks that size.
|
|
|
|
* When optimizing images, inline images are now included in the
|
|
optimization, first being converted to regular images. Use
|
|
--keep-inline-images to exclude them from optimization. Fixes #278.
|
|
|
|
* Add method QPDFPageObjectHelper::externalizeInlineImages, which
|
|
converts inline images whose size is at least a specified amount
|
|
to regular images.
|
|
|
|
* Remove traces of acroread, which hasn't been available in Linux
|
|
for a long time.
|
|
|
|
2019-01-30 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Do not include space after ID operator in inline image data. The
|
|
token now correctly contains the image data, the EI operator,
|
|
and the delimiter that precedes the EI operator.
|
|
|
|
* Improve locating of an inline image's EI operator to correctly
|
|
handle the case of EI appearing inside the image data.
|
|
|
|
* Very low-level QPDFTokenizer API now includes an
|
|
expectInlineImage method that takes an input stream, enabling it
|
|
to locate an inline image's EI operator better. When this method
|
|
is called, the inline image token returned will not contain the EI
|
|
operator and will contain correct image data. This is called
|
|
automatically everywhere within the qpdf library. Most user code
|
|
will never have to use the low-level tokenizer API. If you use
|
|
Pl_QPDFTokenizer, this will be done automatically for you. If you
|
|
use the low-level API and call expectInlineImage, you should call
|
|
the new version.
|
|
|
|
2019-01-29 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Bug fix: when returning an inline image token, the tokenizer no
|
|
longer includes the delimiter that follows EI. The
|
|
QPDFObjectHandle created from the token was correct.
|
|
|
|
* Handle files with direct page objects, which is not allowed by
|
|
the PDF spec but has been seen in the wild. Fixes #164.
|
|
|
|
2019-01-28 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Bug fix: when using --stream-data=compress, object streams and
|
|
xref streams were not compressed. They were compressed if no
|
|
--stream-data option was specified. Fixes #271.
|
|
|
|
* When linearizing or getting the list of all pages in a file,
|
|
replace duplicated page objects with a shallow copy of the page
|
|
object. Linearization and all page manipulation APIs require page
|
|
objects to be unique. Pages that were originally duplicated will
|
|
still share contents and any other indirect resources. Fixes #268.
|
|
|
|
2019-01-26 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Add --overlay and --underlay options. Fixes #207.
|
|
|
|
* Create examples/pdf-overlay-page.cc to demonstrate use of
|
|
page/form XObject interaction
|
|
|
|
* Add new methods QPDFPageObjectHelper::getFormXObjectForPage,
|
|
which creates a form XObject equivalent to a page, and
|
|
QPDFObjectHandle::placeFormXObject, which generates content stream
|
|
code to placing a form XObject on a page.
|
|
|
|
2019-01-25 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Add new method QPDFObjectHandle::getUniqueResourceName() to
|
|
return an unused key available to be used in a resource
|
|
dictionary.
|
|
|
|
* Add new method QPDFPageObjectHelper::getAttribute() that
|
|
properly handles inherited attributes and allows for creation of a
|
|
copy of shared attributes. This is very useful if you are getting
|
|
an attribute of a page dictionary with the intent to modify it
|
|
privately for that page.
|
|
|
|
* Fix QPDFPageObjectHelper::getPageImages (and the legacy
|
|
QPDFObjectHandle::getPageImages()) to properly handle images in
|
|
inherited resources dictionaries.
|
|
|
|
2019-01-20 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Tweak the content code generated for variable text fields to
|
|
better handle font sizes and multi-line text.
|
|
|
|
* When generating appearance streams for variable text
|
|
annotations, properly handle the cases of there being no
|
|
appearance dictionary, no appearance stream, or an appearance
|
|
stream with no BMC..EMC marker.
|
|
|
|
* When flattening annotations, remove annotations from the file
|
|
that don't have appearance streams. These were previously being
|
|
preserved, but since they are invisible, there is no reason to
|
|
preserve them when flattening annotations.
|
|
|
|
2019-01-19 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* NOTE: qpdf CLI: some non-compatible changes were made to how
|
|
qpdf interprets password arguments that contain Unicode characters
|
|
that fall outside of ASCII. On Windows, the non-compatibility was
|
|
unavoidable, as explained in the release notes. On all platforms,
|
|
it is possible to get the old behavior if desired, though the old
|
|
behavior would almost always result in files that other
|
|
applications were unable to open. As it stands, qpdf should now be
|
|
able to open passwords encrypted with a wide range of passwords
|
|
that some other viewers might not handle, though even now, qpdf's
|
|
Unicode password handling is not 100% complete.
|
|
|
|
* Add --password-mode option, which allows fine-grained control of
|
|
how password arguments are treated. This is discussed fully in the
|
|
manual. Fixes #215.
|
|
|
|
* Add option --suppress-password-recovery to disable the behavior
|
|
of searching for a correct password by re-encoding the provided
|
|
password. This option can be useful if you want to ensure you know
|
|
exactly what password is being used.
|
|
|
|
2019-01-17 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* When attempting to open an encrypted file with a password, if
|
|
the password doesn't work, try alternative passwords created by
|
|
re-interpreting the supplied password with different string
|
|
encodings. This makes qpdf able to recover passwords with
|
|
non-ASCII characters when either the decryption or encryption
|
|
operation was performed with an incorrectly encoded password.
|
|
|
|
* Fix data loss bug: qpdf was discarding referenced resources in
|
|
the case in which a page's resource dictionary contained an
|
|
indirect reference for either /Font or /XObject that contained
|
|
fonts or XObjects not referenced on all pages that shared the
|
|
resource. This was a "typo" in the code. The comment explained the
|
|
correct behavior, and the code was clearly intended to handle this
|
|
issue, but the implementation had an error in it. This is fixed by
|
|
a single-line change, which can be found in git commit
|
|
4bc434000c42a7191e705c8a38216ca6743ad9ff. That commit can be used
|
|
as a patch that applies cleanly against qpdf 8.1.0 and forward.
|
|
The bug was introduced in version 8.1.0. For the record, this is
|
|
the first bug in qpdf's history that could result in silent loss
|
|
of data when processing a correct input file. Fixes #276.
|
|
|
|
2019-01-15 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Add QUtil::possible_repaired_encodings which, given a string,
|
|
generates other strings that represent re-interpretation of the
|
|
bytes in a different coding system. This is used to help recover
|
|
passwords if the password string was improperly encoded on a
|
|
different system due to user error or a software bug.
|
|
|
|
2019-01-14 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Add new CLI flags to 128-bit and 256-bit encryption: --assemble,
|
|
--annotate, --form, and --modify-other to control encryption
|
|
permissions with more granularity than was allowed with the
|
|
--modify flag. Fixes #214.
|
|
|
|
* Add new versions of
|
|
QPDFWriter::setR{3,4,5,6}EncryptionParameters that allow
|
|
individual setting of the various permission bits. The old
|
|
interfaces are retained for backward compatibility. In the "C"
|
|
API, add qpdf_set_r{3,4,5,6}_encryption_parameters2. The new
|
|
interfaces use separate booleans for various permissions instead
|
|
of the qpdf_r3_modify_e enumerated type, which set permission bits
|
|
in predefined groups.
|
|
|
|
* Add versions of utf8 to single-byte character transcoders that
|
|
return a success code.
|
|
|
|
2019-01-13 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Add several more string transcoding and analysis methods to
|
|
QUtil for bidirectional conversion between PDF Doc, Win Ansi, Mac
|
|
Roman, UTF-6, and UTF-16 along with detection of valid UTF-8 and
|
|
UTF-16.
|
|

|
|
|
|
* In the --pages option, allow the same page to be specified more
|
|
than once. You can now do "--pages A.pdf 1,1 --" or
|
|
"--pages A.pdf 1 A.pdf 1" instead of having to use two different
|
|
paths to specify A.pdf. Fixes #272.
|
|
|
|
* Add QPDFPageObjectHelper::shallowCopyPage(). This method creates
|
|
a new page object that is a "shallow copy" of the given page as
|
|
described in the comments in QPDFPageObjectHelper. The resulting
|
|
object has not been added anywhere but is ready to be passed to
|
|
QPDFPageDocumentHelper::addPage of its own QPDF or another QPDF
|
|
object.
|
|
|
|
* Add QPDF::getUniqueId() method to return an identifier that is
|
|
intended to be unique within the scope of all QPDF objects created
|
|
by the calling application in a single run.
|
|
|
|
* In --pages, allow "." as a replacement for the current input
|
|
file, making it possible to say "qpdf A.pdf --pages . 1-3 --"
|
|
instead of having to repeat the input filename.
|
|
|
|
2019-01-10 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Add new configure option --enable-avoid-windows-handle, which
|
|
causes the symbol AVOID_WINDOWS_HANDLE to be defined. If set, we
|
|
avoid using Windows I/O HANDLE, which is disallowed in some
|
|
versions of the Windows SDK, such as for Windows phones.
|
|
QUtil::same_file will always return false in this case. Only
|
|
applies to Windows builds.
|
|
|
|
* Add new method QPDF::setImmediateCopyFrom. When called on a
|
|
source QPDF object, streams can be copied FROM that object to
|
|
other ones without having to keep the source QPDF or its input
|
|
source around. The cost is copying the streams into RAM. See
|
|
comments in QPDF.hh for setImmediateCopyFrom for a detailed
|
|
explanation.
|
|
|
|
2019-01-07 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* 8.3.0: release
|
|
|
|
* Add sample completion files in completions. These can be used by
|
|
packagers to install on the system wherever bash and zsh keep
|
|
their vendor-supplied completions.
|
|
|
|
* Add configure flag --enable-check-autofiles, which is on by
|
|
default. Packagers whose packaging systems automatically refresh
|
|
autoconf or libtool files should pass --disable-check-autofiles to
|
|
./configure to suppress warnings about automatically generated
|
|
files being outdated.
|
|
|
|
2019-01-06 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Remove the restriction in most cases that the source QPDF used
|
|
in a copyForeignObject call has to stick around until the
|
|
destination QPDF is written. The exceptional case is when the
|
|
source stream gets is data using a
|
|
QPDFObjectHandle::StreamDataProvider. For a more in-depth
|
|
discussion, see comments around copyForeignObject in QPDF.hh.
|
|
Fixes #219.
|
|
|
|
2019-01-05 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* When generating appearances, if the font uses one of the
|
|
standard, built-in encodings, restrict the character set to that
|
|
rather than just to ASCII. This will allow most appearances to
|
|
contain characters from the ISO-Latin-1 range plus a few
|
|
additional characters.
|
|
|
|
* Add methods QUtil::utf8_to_win_ansi and
|
|
QUtil::utf8_to_mac_roman.
|
|
|
|
* Add method QUtil::utf8_to_utf16.
|
|
|
|
2019-01-04 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Add new option --optimize-images, which recompresses every image
|
|
using DCT (JPEG) compression as long as the image is not already
|
|
compressed with lossy compression and recompressing the image
|
|
reduces its size. The additional options --oi-min-width,
|
|
--oi-min-height, and --oi-min-area prevent recompression of images
|
|
whose width, height, or pixel area (width * height) are below a
|
|
specified threshold.
|
|
|
|
* Add new option --collate. When specified, the semantics of
|
|
--pages change from concatenation to collation. See the manual for
|
|
a more detailed discussion. Fixes #259.
|
|
|
|
* Add new method QPDFWriter::getFinalVersion, which returns the
|
|
PDF version that will ultimately be written to the final file. See
|
|
comments in QPDFWriter.hh for some restrictions on its use. Fixes
|
|
#266.
|
|
|
|
* When unexpected errors are found while checking linearization
|
|
data, print an error message instead of calling assert, which
|
|
cause the program to crash. Fixes #209, #231.
|
|
|
|
* Detect and recover from dangling references. If a PDF file
|
|
contained an indirect reference to a non-existent object (which is
|
|
valid), when adding a new object to the file, it was possible for
|
|
the new object to take the object ID of the dangling reference,
|
|
thereby causing the dangling reference to point to the new object.
|
|
This case is now prevented. Fixes #240.
|
|
|
|
2019-01-03 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Add --generate-appearances flag to the qpdf command-line tool to
|
|
trigger generation of appearance streams.
|
|
|
|
* Fix behavior of form field value setting to handle the following
|
|
cases:
|
|
- Strings are always written as UTF-16
|
|
- Check boxes and radio buttons are handled properly with
|
|
synchronization of values and appearance states
|
|
|
|
* Define constants in qpdf/Constants.h for interpretation of
|
|
annotation and form field flags
|
|
|
|
* Add QPDFAnnotationObjectHelper::getFlags
|
|
|
|
* Add many new methods to QPDFFormFieldObjectHelper for querying
|
|
flags and field types
|
|
|
|
* Add new methods for appearance stream generation. See comments
|
|
in QPDFFormFieldObjectHelper.hh for generateAppearance() for a
|
|
description of limitations.
|
|
- QPDFAcroFormDocumentHelper::generateAppearancesIfNeeded
|
|
- QPDFFormFieldObjectHelper::generateAppearance
|
|
|
|
* Bug fix: when writing form field values, always write string
|
|
values encoded as UTF-16.
|
|
|
|
* Add method QUtil::utf8_to_ascii, which returns an ASCII string
|
|
for a UTF-8 string, replacing out-of-range characters with a
|
|
specified substitute.
|
|
|
|
2019-01-02 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Add method QPDFObjectHandle::getResourceNames that returns a set
|
|
of strings representing all second-level keys in a dictionary
|
|
(i.e. all keys of all direct dictionary members).
|
|
|
|
2018-12-31 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Add --flatten-annotations flag to the qpdf command-line tool for
|
|
annotation flattening.
|
|
|
|
* Add methods for flattening form fields and annotations:
|
|
- QPDFPageDocumentHelper::flattenAnnotations - integrate
|
|
annotation appearance streams into page contents with special
|
|
handling for form fields: if appearance streams are up to date
|
|
(/NeedAppearances is false in /AcroForm), the /AcroForm key of
|
|
the document catalog is removed. Otherwise, a warning is
|
|
issued, and form fields are ignored. Non-form-field
|
|
annotations are always flattened if an appearance stream can
|
|
be found.
|
|
- QPDFAnnotationObjectHelper::getPageContentForAppearance -
|
|
generate the content stream fragment to render an appearance
|
|
stream in a page's content stream as a form xobject. Called by
|
|
flattenAnnotations.
|
|
|
|
* Add method QPDFObjectHandle::mergeResources(), which merges
|
|
resource dictionaries. See detailed description in
|
|
QPDFObjectHandle.hh.
|
|
|
|
* Add QPDFObjectHandle::Matrix, similar to
|
|
QPDFObjectHandle::Rectangle, as a convenience class for
|
|
six-element arrays that are used as matrices.
|
|
|
|
2018-12-23 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* When specifying @arg on the command line, if the file "arg" does
|
|
not exist, just treat this is a normal argument. This makes it
|
|
easier to deal with files whose names start with the @ character.
|
|
Fixes #265.
|
|
|
|
* Tweak completion so it works with zsh as well using
|
|
bashcompinit.
|
|
|
|
2018-12-22 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Add new options --json, --json-key, and --json-object to
|
|
generate a json representation of the PDF file. This is described
|
|
in more depth in the manual. You can also run qpdf --json-help to
|
|
get a description of the json format.
|
|
|
|
2018-12-21 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Allow --show-object=trailer for showing the document trailer.
|
|
|
|
* You can now use eval $(qpdf --completion-bash) to enable bash
|
|
completion for qpdf. It's not perfect, but it works pretty well.
|
|
|
|
2018-12-19 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* When splitting pages using --split-pages, the outlines
|
|
dictionary and some supporting metadata are copied into the split
|
|
files. The result is that all bookmarks from the original file
|
|
appear, and those that point to pages that are preserved work
|
|
while those that point to pages that are not preserved don't do
|
|
anything. This is an interim step toward proper support for
|
|
bookmark preservation in split files.
|
|
|
|
* Add QPDFOutlineDocumentHelper and QPDFOutlineObjectHelper for
|
|
handling outlines (bookmarks) including bidirectionally mapping
|
|
between bookmarks and pages. Initially there is no support for
|
|
modifying the outlines hierarchy.
|
|
|
|
2018-12-18 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* New method QPDFObjectHandle::getJSON() returns a JSON object
|
|
with a partial representation of the object. See
|
|
QPDFObjectHandle.hh for a detailed description.
|
|
|
|
* Add a simple JSON serializer. This is not a complete or
|
|
general-purpose JSON library. It allows assembly and serialization
|
|
of JSON structures with some restrictions, which are described in
|
|
the header file.
|
|
|
|
* Add QPDFNameTreeObjectHelper class. This class provides useful
|
|
methods for dealing with name trees, which are discussed in
|
|
section 7.9.6 of the PDF spec (ISO-32000).
|
|
|
|
* Preserve page labels when merging and splitting files. Prior
|
|
versions of qpdf simply preserved the page label information from
|
|
the first file, which usually wouldn't make any sense in the
|
|
merged file. Now any page that had a page number in any original
|
|
file will have the same page number after merging or splitting.
|
|
|
|
* Add QPDFPageLabelDocumentHelper class. This is a document helper
|
|
class that provides useful methods for dealing with page labels.
|
|
It abstracts the fact that they are stored as number trees and
|
|
deals with interpolating intermediate values that are not in the
|
|
tree. It also has helper functions used by the qpdf command line
|
|
tool to preserve page labels when merging and splitting files.
|
|
|
|
* Add QPDFNumberTreeObjectHelper class. This class provides useful
|
|
methods for dealing with number trees, which are discussed in
|
|
section 7.9.7 of the PDF spec (ISO-32000). Page label dictionaries
|
|
are represented as number trees.
|
|
|
|
* New method QPDFObjectHandle::wrapInArray returns the object
|
|
itself if it is an array. Otherwise, it returns an array
|
|
containing the object. This is useful for dealing with PDF data
|
|
that is sometimes expressed as a single element and sometimes
|
|
expressed as an array, which is a somewhat common PDF idiom.
|
|
|
|
2018-10-11 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Files generated by autogen.sh are now committed so that it is
|
|
possible to build on platforms without autoconf directly from a
|
|
clean checkout of the repository. The configure script detects if
|
|
the files are out of date when it also determines that the tools
|
|
are present to regenerate them.
|
|
|
|
* Add build in Azure Pipelines, now that it is free for open
|
|
source projects.
|
|
|
|
2018-08-18 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* 8.2.1: release
|
|
|
|
* Add new option --keep-files-open=[yn] to control whether qpdf
|
|
keeps files open when merging. Prior to version 8.1.0, qpdf always
|
|
kept all files open, but this meant that the number of files that
|
|
could be merged was limited by the operating system's open file
|
|
limit. Version 8.1.0 opened files as they were referenced, but
|
|
this caused a major performance impact. Version 8.2.0 optimized
|
|
the performance but did so in a way that, for local file systems,
|
|
there was a small but unavoidable performance hit, but for
|
|
networked file systems, the performance impact could be very high.
|
|
Starting with version 8.2.1, the default behavior is that files
|
|
are kept open if no more than 200 files are specified, but that
|
|
the behavior can be explicitly overridden with the
|
|
--keep-files-open flag. If you are merging more than 200 files but
|
|
less than the operating system's max open files limit, you may
|
|
want to use --keep-files-open=y. If you are using a local file
|
|
system where the overhead is low and you might sometimes merge
|
|
more than the OS limit's number of files, you may want to specify
|
|
--keep-files-open=n. Fixes #237.
|
|
|
|
2018-08-16 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* 8.2.0: release
|
|
|
|
2018-08-14 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* For the mingw builds, change the name of the DLL import library
|
|
from libqpdf.a to libqpdf.dll.a to avoid confusing it with a
|
|
static library. This potentially clears the way for supporting a
|
|
static library in the future, though presently, the qpdf Windows
|
|
build only builds the DLL and executables. Fixes #225.
|
|
|
|
2018-08-13 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Add new class QPDFSystemError, derived from std::runtime_error,
|
|
which is now thrown by QUtil::throw_system_error. This enables the
|
|
triggering errno value to be retrieved. Fixes #221.
|
|
|
|
2018-08-12 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* qpdf command line: add --no-warn option to suppress issuing
|
|
warning messages. If there are any conditions that would have
|
|
caused warnings to be issued, the exit status is still 3.
|
|
|
|
* Rewrite the internals of Pl_Buffer to be much more efficient in
|
|
use of memory at a very slight performance cost. The old
|
|
implementation could cause memory usage to go out of control for
|
|
files with large images compressed using the TIFF predictor.
|
|
Fixes #228.
|
|
|
|
2018-08-05 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Bug fix: end of line characters were not properly handled inside
|
|
strings in some cases. Fixes #226.
|
|
|
|
* Bug fix: infinite loop on progress reporting for very small
|
|
files. Fixes #230.
|
|
|
|
2018-08-04 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Performance fix: optimize page merging operation to avoid
|
|
unnecessary open/close calls on files being merged. Fixes #217.
|
|
|
|
* Add ClosedFileInputSource::stayOpen method, enabling a
|
|
ClosedFileInputSource to stay open during manually indicated
|
|
periods of high activity, thus reducing the overhead of frequent
|
|
open/close operations.
|
|
|
|
2018-06-23 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* 8.1.0: release
|
|
|
|
2018-06-22 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Bug fix: properly decrypt files with 40-bit keys that use
|
|
revision 3 of the security handler. Prior to this, qpdf was
|
|
reporting "invalid password" in this case. Fixes #212.
|
|
|
|
* With --verbose, print information about each input file when
|
|
merging files.
|
|
|
|
* Add progress reporting to QPDFWriter. Programmatically, you can
|
|
register a progress reporter with registerProgressReporter(). From
|
|
the command line, passing --progress will give progress indicators
|
|
in increments of no less than 1% as output files are written.
|
|
Fixes #200.
|
|
|
|
* Add new method QPDF::getObjectCount(). This gives an approximate
|
|
(upper bound) account of objects in the QPDF object.
|
|
|
|
* Don't leave files open when merging. This makes it possible
|
|
merge more files at once than the operating system's open file
|
|
limit. Fixes #154.
|
|
|
|
* Add ClosedFileInputSource class, and input source that keeps its
|
|
input file closed when not reading it. At the expense of some
|
|
performance, this allows you to operate on many files without
|
|
opening too many files at the operating system level.
|
|
|
|
* Add new option --preserve-unreferenced-resources, which
|
|
suppresses removal of unreferenced objects from page resource
|
|
dictionaries during page splitting operations.
|
|
|
|
2018-06-21 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Add method QPDFPageObjectHelper::removeUnreferencedResources and
|
|
also QPDFPageDocumentHelper::removeUnreferencedResources that
|
|
calls the former on every page. This method removes any XObject or
|
|
Font references from the page's resource dictionary if they are
|
|
not referenced anywhere in any of the content streams. This
|
|
significantly reduces the size of split files whose pages
|
|
internally share resource dictionaries. Fixes #203.
|
|
|
|
* The --rotate option to qpdf no longer requires an explicit page
|
|
range. You can now rotate all pages of a document with
|
|
qpdf --rotate=angle in.pdf out.pdf. Fixes #211.
|
|
|
|
* Create examples/pdf-set-form-values.cc to illustrate use of
|
|
interactive form helpers.
|
|
|
|
* Added methods QPDFAcroFormDocumentHelper::setNeedAppearances and
|
|
added methods to QPDFFormFieldObjectHelper to set a field's value,
|
|
optionally updating the document to indicate that appearance
|
|
streams need to be regenerated.
|
|
|
|
* Added QPDFObject::newUnicodeString and QPDFObject::unparseBinary
|
|
to allow for more convenient creation of strings that are
|
|
explicitly encoded in UTF-16 BE. This is useful for creating
|
|
Unicode strings that appear outside of content streams, such as in
|
|
page labels, outlines, form field values, etc.
|
|
|
|
2018-06-20 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Added new classes QPDFAcroFormDocumentHelper,
|
|
QPDFFormFieldObjectHelper, and QPDFAnnotationObjectHelper to
|
|
assist with working with interactive forms in PDF files. At
|
|
present, API methods for reading forms, form fields, and widget
|
|
annotations have been added. It is likely that some additional
|
|
methods for modifying forms will be added in the future. Note that
|
|
qpdf remains a library whose function is primarily focused around
|
|
document structure and metadata rather than content. As such, it
|
|
is not expected that qpdf will have higher level APIs for
|
|
generating form contents, but qpdf will hopefully gain the
|
|
capability to deal with the bookkeeping aspects of wiring up all
|
|
the objects, which could make it a useful library for other
|
|
software that works with PDF interactive forms. PDF forms are
|
|
complex, and the terminology around them is confusing. Please see
|
|
comments at the top of QPDFAcroFormDocumentHelper.hh for
|
|
additional discussion.
|
|
|
|
* Added new classes QPDFPageDocumentHelper and QPDFPageObjectHelper
|
|
for page-level API functions. These classes introduce a new API
|
|
pattern of document helpers and object helpers in qpdf. The helper
|
|
classes provide a higher level API for working with certain types
|
|
of structural features of PDF while still staying true to qpdf's
|
|
philosophy of not isolating the user from the underlying
|
|
structure. Please see the chapter in the documentation entitled
|
|
"Design and Library Notes" for additional discussion. The examples
|
|
have also been updated to use QPDFPageDocumentHelper and
|
|
QPDFPageObjectHelper when performing page-level operations.
|
|
|
|
2018-06-19 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* New QPDFObject::Rectangle class will convert to and from arrays
|
|
of four numerical values. Rectangles are used in various places
|
|
within the PDF file format and are called out as a specific data
|
|
type in the PDF specification.
|
|

* In newline before endstream mode, an extra newline was not
|
|
inserted prior to the endstream that ends object streams.
|
|
Fixes #205.

* Properly handle pages with no contents. Fixes #194.
|
|
|
|
2018-03-05 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Improve handling of loops while following cross reference

tables. Fixes #192.
|
|
|
|
2018-03-04 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* 8.0.1: release
|
|
|
|
* On the command line when specifying page ranges, support
|
|
preceding a page number by "r" to indicate that it should be
|
|
counted from the end. For example, the range r3-r1 would indicate
|
|
the last three pages of a document.
|
|
|
|
2018-03-03 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Ignore zlib data check errors while uncompressing streams. This
|
|
is consistent with behaviors of other readers and enables handling
|
|
of some incorrectly written zlib streams. Fixes #191.
|
|
|
|
2018-02-25 Jay Berkenbilt <ejb@ql.org>

* Fix QPDFObjectHandle::getUTF8Val() to properly handle strings
|
|
that are encoded with PDF Doc Encoding. Fixes #179.
|
|
|
|
* Add qpdf_check_pdf to the "C" API. This method just attempts to
|
|
read the entire file and produce no output, making possible to
|
|
assess whether the file has any errors that qpdf can detect.
|
|
|
|
* Major enhancements to handling of type errors within the qpdf
|
|
library. This fix is intended to eliminate those annoying cases
|
|
where qpdf would exit with a message like "operation for
|
|
dictionary object attempted on object of wrong type" without
|
|
providing any context. Now qpdf keeps enough context to be able to
|
|
issue a proper warning and to handle such conditions in a sensible
|
|
way. This should greatly increase the number of bad files that
|
|
qpdf can recover, and it should make it much easier to figure out
|
|
what's broken when a file contains errors.
|
|
|
|
* Error message fix: replace "file position" with "offset" in
|
|
error messages that report lexical or parsing errors. Sometimes
|
|
it's an offset in an object stream or a content stream rather than
|
|
a file position, so this makes the error message less confusing in
|
|
those cases. It still requires some knowledge to find the exact
|
|
position of the error, since when it's not a file offset, it's
|
|
probably an offset into a stream after uncompressing it.
|
|
|
|
* Error message fix: correct some cases in which the object that
|
|
contained a lexical error was omitted from the error message.
|
|
|
|
* Error message fix: improve file name in the error message when
|
|
there is a parser error inside an object stream.

|
|
|
|
* Add QPDFObjectHandle::filterPageContents method to provide a
|
|
different interface for applying token filters to page contents
|
|
without modifying the ultimate output.
|
|
|
|
2018-02-04 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Changes listed on today's date are numerous and reflect
|
|
significant enhancements to qpdf's lexical layer. While many
|
|
nuances are discussed and a handful of small bugs were fixed, it
|
|
should be emphasized that none of these issues have any impact on
|
|
any output or behavior of qpdf under "normal" operation. There are
|
|
some changes that have an effect on content stream normalization
|
|
as with qdf mode or on code that interacts with PDF files
|
|
lexically using QPDFTokenizer. There are no incompatible changes
|
|
for normal operation. There are a few changes that will affect the
|
|
exact error messages issued on certain bad files, and there is a
|
|
small non-compatible enhancement regarding the behavior of
|
|
manually constructed QPDFTokenizer::Token objects. Users of the
|
|
qpdf command line tool will see no changes other than the addition
|
|
of a new command-line flag and possibly some improved error
|
|
messages.
|
|
|
|
* Significant lexer (tokenizer) enhancements. These are changes to
|
|
the QPDFTokenizer class. These changes are of concern only to
|
|
people who are operating with PDF files at the lexical layer using
|
|
qpdf. They have little or no impact on most high-level interfaces
|
|
or the command-line tool.
|
|
|
|
New token types tt_space and tt_comment to recognize whitespace
|
|
and comments. this makes it possible to tokenize a PDF file or
|
|
stream and preserve everything about it.
|
|
|
|
For backward compatibility, space and comment tokens are not
|
|
returned by the tokenizer unless QPDFTokenizer.includeIgnorable()
|
|
is called.
|
|
|
|
Better handling of null bytes. These are now included in space
|
|
tokens rather than being their own "tt_word" tokens. This should
|
|
have no impact on any correct PDF file and has no impact on
|
|
output, but it may change offsets in some error messages when
|
|
trying to parse contents of bad files. Under default operation,
|
|
qpdf does not attempt to parse content streams, so this change is
|
|
mostly invisible.
|
|
|
|
Bug fix to handling of bad tokens at ends of streams. Now, when
|
|
allowEOF() has been called, these are treated as bad tokens
|
|
(tt_bad or an exception, depending on invocation), and a
|
|
separate tt_eof token is returned. Before the bad token
|
|
contents were returned as the value of a tt_eof token. tt_eof
|
|
tokens are always empty now.
|
|
|
|
Fix a bug that would, on rare occasions, report the offset in an
|
|
error message in the wrong space because of spaces or comments
|
|
adjacent to a bad token.
|
|
|
|
Clarify in comments exactly where the input source is positioned
|
|
surrounding calls to readToken and getToken.
|
|
|
|
* Add a new token type for inline images. This token type is only
|
|
returned by QPDFTokenizer immediately following a call to
|
|
expectInlineImage(). This change includes internal refactoring of
|
|
a handful of places that all separately handled inline images, The
|
|
logic of detecting inline images in content streams is now handled
|
|
in one place in the code. Also we are more flexible about what
|
|
characters may surround the EI operator that marks the end of an
|
|
inline image.
|
|
|
|
* New method QPDFObjectHandle::parsePageContents() to improve upon
|
|
QPDFObjectHandle::parseContentStream(). The parseContentStream
|
|
method used to operate on a single content stream, but was fixed
|
|
to properly handle pages with contents split across multiple
|
|
streams in an earlier release. The new method parsePageContents()
|
|
can be called on the page object rather than the value of the
|
|
page dictionary's /Contents key. This removes a few lines of
|
|
boiler-plate code from any code that uses parseContentStream, and
|
|
it also enables creation of more helpful error messages if
|
|
problems are encountered as the error messages can include
|
|
information about which page the streams come from.
|
|
|
|
* Update content stream parsing example
|
|
(examples/pdf-parse-content.cc) to use new
|
|
QPDFObjectHandle::parsePageContents() method in favor of the older
|
|
QPDFObjectHandle::parseContentStream() method.
|
|
|
|
* Bug fix: change where the trailing newline is added to a stream
|
|
in QDF mode when content normalization is enabled (the default for
|
|
QDF mode). Before, the content normalizer ensured that the output
|
|
ended with a trailing newline, but this had the undesired side
|
|
effect of including the newline in the stream data for purposes of
|
|
length computation. QPDFWriter already appends a newline without
|
|
counting in length for better readability. Ordinarily this makes
|
|
no difference, but in the rare case of a page's contents being
|
|
split in the middle of a token, the old behavior could cause the
|
|
extra newline to be interpreted as part of the token. This bug
|
|
could only be triggered in qdf mode, which is a mode intended for
|
|
manual inspection of PDF files' contents, so it is very unlikely
|
|
to have caused any actual problems for people using qpdf for
|
|
production use. Even if it did, it would be very unusual for a PDF
|
|
file to actually be adversely affected by this issue.
|
|
|
|
* Add support for coalescing a page's contents into a single
|
|
stream if they are represented as an array of streams. This can be
|
|
performed from the command line using the --coalesce-contents
|
|
option. Coalescing content streams can simplify things for
|
|
software that wants to operate on a page's content streams without
|
|
having to handle weird edge cases like content streams split in
|
|
the middle of tokens. Note that
|
|
QPDFObjectHandle::parsePageContents and
|
|
QPDFObjectHandle::parseContentStream already handled split content
|
|
streams. This is mainly to set the stage for new methods of
|
|
operating on page contents. The new method
|
|
QPDFObjectHandle::pipeContentStreams will pipe all of a page's
|
|
content streams though a single pipeline. The new method
|
|
QPDFObjectHandle.coalesceContentStreams, when called on a page
|
|
object, will do nothing if the page's contents are a single
|
|
stream, but if they are an array of streams, it will replace the
|
|
page's contents with a single stream whose contents are the
|
|
concatenation of the original streams.
|
|
|
|
* A few library routines throw exceptions if called on non-page
|
|
objects. These constraints have been relaxed somewhat to make qpdf
|
|
more tolerant of files whose page dictionaries are not properly
|
|
marked as such. Mostly exceptions about page operations being
|
|
called on non page objects will only be thrown in cases where the
|
|
operation had no chance of succeeding anyway. This change has no
|
|
impact on any default mode operations, but it could allow
|
|
applications that use page-level APIs in QPDFObjectHandle to be
|
|
more tolerant of certain types of damaged files.
|
|
|
|
* Add QPDFObjectHandle::TokenFilter class and methods to use it to
|
|
perform lexical filtering on content streams. You can call
|
|
QPDFObjectHandle::addTokenFilter on stream object, or you can call
|
|
the higher level QPDFObjectHandle::addContentTokenFilter on a page
|
|
object to cause the stream's contents to passed through a token
|
|
filter while being retrieved by QPDFWriter or any other consumer.
|
|
For details on using TokenFilter, please see comments in
|
|
QPDFObjectHandle.hh.
|
|
|
|
* Enhance the string, type QPDFTokenizer::Token constructor to
|
|
initialize a raw value in addition to a value. Tokens have a
|
|
value, which is a canonical representation, and a raw value. For
|
|
all tokens except strings and names, the raw value and the value
|
|
are the same. For strings, the value excludes the outer delimiters
|
|
and has non-printing characters normalized. For names, the value
|
|
resolves non-printing characters. In order to better facilitate
|
|
token filters that mostly preserve contents and to enable
|
|
developers to be mostly unconcerned about the nuances of token
|
|
values and raw values, creating string and name tokens now
|
|
properly handles this subtlety of values and raw values. When
|
|
constructing string tokens, take care to avoid passing in the
|
|
outer delimiters. This has always been the case, but it is now
|
|
clarified in comments in QPDFObjectHandle.hh::TokenFilter. This
|
|
has no impact on any existing code unless there's some code
|
|
somewhere that was relying on Token::getRawValue() returning an
|
|
empty string for a manually constructed token. The token class's
|
|
operator== method still only looks at type and value, not raw
|
|
value. For example, string tokens for <41> and (A) would still be
|
|
equal because both are representations of the string "A".
|
|
|
|
* Add QPDFObjectHandle::isDataModified method. This method just
|
|
returns true if addTokenFilter has been called on the stream. It
|
|
enables a caller to determine whether it is safe to optimize away
|
|
piping of stream data in cases where the input and output are
|
|
expected to be the same. QPDFWriter uses this internally to skip
|
|
the optimization of not re-compressing already compressed streams
|
|
if addTokenFilter has been called. Most developers will not have
|
|
to worry about this as it is used internally in the library in the
|
|
places that need it. If you are manually retrieving stream data
|
|
with QPDFObjectHandle::getStreamData or
|
|
QPDFObjectHandle::pipeStreamData, you don't need to worry about
|
|
this at all.
|
|
|
|
* Provide heavily annotated examples/pdf-filter-tokens.cc example
|
|
that illustrates use of some simple token filters.
|
|
|
|
* When normalizing content streams, as in qdf mode, issue warning
|
|
about bad tokens. Content streams are only normalized when this is
|
|
explicitly requested, so this has no impact on normal operation.
|
|
However, in qdf mode, if qpdf detects a bad token, it means that
|
|
either there's a bug in qpdf's lexer, that the file is damaged, or
|
|
that the page's contents are split in a weird way. In any of those
|
|
cases, qpdf could potentially damage the stream's contents by
|
|
replacing carriage returns with newlines or otherwise messing with
|
|
spaces. The mostly likely case of this would be an inline image's
|
|
compressed data being divided across two streams and having the
|
|
compressed data in the second stream contain a carriage return as
|
|
part of its binary data. If you are using qdf mode just to look at
|
|
PDF files in text editors, this usually doesn't matter. In cases
|
|
of contents split across multiple streams, coalescing streams
|
|
would eliminate the problem, so the warning mentions this. Prior
|
|
to this enhancement, the chances of qdf mode writing incorrect
|
|
data were already very low. This change should make it nearly
|
|
impossible for qdf mode to unknowingly write invalid data.
|

|
|
|
|
* Add QPDFWriter::setLinearizationPass1Filename method and
|
|
--linearize-pass1 command line option to allow specification of a
|
|
file into which QPDFWriter will write its intermediate
|
|
linearization pass 1 file. This is useful only for debugging qpdf.
|
|
qpdf creates linearized files by computing the output in two
|
|
passes. Ordinarily the first pass is discarded and not written
|
|
anywhere. This option allows it to be inspected.
|
|
|
|
2018-02-04 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* 7.1.1: release
|
|
|
|
* Bug fix: properly linearize files whose /ID has a length of
|
|
other than 16 bytes.
|
|
|
|
* Rename some test files to avoid files with three dots in their
|
|
names. Fixes #173.
|
|
|
|
* Fix various build and compilation issues on some platforms and
|
|
compilers. Fixes #176, #172, #177
|
|
|
|
* Fix a few typos and clarify a few comments in header files.
|
|
|
|
2018-01-14 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* 7.1.0: release
|
|
|
|
* Allow raw encryption key to be specified in library and command
|
|
line with the QPDF::setPasswordIsHexKey method and
|
|
--password-is-hex-key option. Allow encryption key to be displayed
|
|
with --show-encryption-key option. Thanks to Didier Stevens
|
|
<didier.stevens@gmail.com> for the idea and contribution of one
|
|
implementation of this idea. See his blog post at
|
|
https://blog.didierstevens.com/2017/12/28/cracking-encrypted-pdfs-part-3/
|
|
for a discussion of using this for cracking encrypted PDFs. I hope
|
|
that a future release of qpdf will include some additional
|
|
recovery options that may also make use of this capability.
|
|
|
|
2018-01-13 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Fix lexical error: the PDF specification allows floating point
|
|
numbers to end with ".". Fixes #165.
|
|
|
|
* Fix link order in the build to avoid conflicts when building
|
|
from source while an older version of qpdf is installed. Fixes #158.
|
|
|
|
* Add support for TIFF predictor for LZW and Flate streams. Now
|
|
all predictor functions are supported. Fixes #171.
|
|
|
|
2017-12-25 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Clarify documentation around options that control parsing but
|
|
not output creation. Two options: --suppress-recovery and
|
|
--ignore-xref-streams, were documented in the "Advanced
|
|
Transformation Options" section of the manual and --help output
|
|
even though they are not related to output. These are now
|
|
described in a separate section called "Advanced Parsing Options."
|
|
|
|
* Implement remaining PNG filters for decode. Prior versions could
|
|
decode only the "up" filter. Now all PNG filters (sub, up,
|
|
average, Paeth, optimal) are supported for decoding. Thanks to
|
|
Tobias Hoffmann for providing a test PDF file that has images with
|
|
all PNG filters along with different numbers of bits per sample
|
|
and samples per pixel, and thanks to Casey Rojas for providing
|
|
implementations of the remaining PNG filters.
|
|
|
|
The implementation of the remaining PNG filters changed the
|
|
interface to the private Pl_PNGFilter class, but this class's
|
|
header file is not in the installation, and there is no public
|
|
interface to the class. Within the library, the class is never
|
|
allocated on the stack; it is only ever dynamically allocated. As
|
|
such, this does not actually break binary compatibility of the
|
|
library.
|
|
|
|
2017-09-15 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* 7.0.0: release
|
|
|
|
2017-09-12 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Relicense qpdf under version 2.0 of the Apache License rather
|
|
than version 2.0 of the Artistic License. Both are fine, but the
|
|
Apache License is in more widespread use, and I like it a little
|
|
better than Artistic-2.0. It is my intention that there be no
|
|
change in what you can or can't do with qpdf. Versions of qpdf
|
|
prior to version 7 were released under the terms of version 2.0 of
|
|
the Artistic License. At your option, you may continue to consider
|
|
qpdf to be licensed under those terms. Please see the manual for
|
|
additional information.
|
|
|
|
* Improve the error message that is issued when QPDFWriter
|
|
encounters a stream that can't be decoded. In particular, mention
|
|
that the stream will be copied without filtering to avoid data
|
|
loss.
|
|
|
|
* Add new methods to the C API to correspond to new additions to
|
|
QPDFWriter:
|
|
- qpdf_set_compress_streams
|
|
- qpdf_set_decode_level
|
|
- qpdf_set_preserve_unreferenced_objects
|
|
- qpdf_set_newline_before_endstream
|
|
|
|
2017-08-25 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Re-implement parser iteratively to avoid stack overflow on very
|
|
deeply nested arrays and dictionaries. Fixes #146.
|
|
|
|
* Detect infinite loop while finding additional xref tables. Fixes
|
|
#149.
|
|
|
|
2017-08-22 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* 7.0.b1: release
|
|
|
|
* Convert all README files to markdown. Names changed as follows:
|
|
- README --> README.md
|
|
- README.hardening --> README-hardening.md
|
|
- README.maintainer --> README-maintainer.md
|
|
- README-what-to-download.txt --> README-what-to-download.md
|
|
- README-windows.txt --> README-windows.md
|
|
The file README-windows-install.txt remains a text file.
|
|
|
|
2017-08-21 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Add support for writing PCLm files. Most of the work was done by
|
|
Sahil Arora <sahilarora.535@gmail.com> as part of a Google Summer
|
|
of Code project in 2017. PCLm support is useful only for clients
|
|
that specifically know how to create PCLm files. Support in qpdf
|
|
is just for ensuring that objects are written in the correct order
|
|
and for including some additional material in the output that is
|
|
required by the PCLm standard.
|
|
|
|
2017-08-19 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Remove --precheck-streams. This is enabled by default now
|
|
without any efficiency cost. This feature was never released.
|
|
|
|
* Update pdf-create example to illustrate use of additional image
|
|
compression filters.
|
|
|
|
* Add support for /RunLengthDecode and /DCTDecode:
|
|
- New pipeline types Pl_RunLength and Pl_DCT
|
|
- New command-line flags --compress-streams and --decode-level
|
|
to replace/enhance --stream-data
|
|
- New QPDFWriter::setCompressStreams and
|
|
QPDFWriter::setDecodeLevel methods
|
|
Please see documentation, header files, and help messages for
|
|
details on these new features.
|
|
|
|
2017-08-12 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Add QPDFObjectHandle::rotatePage to apply rotation to a page
|
|
object. Add --rotate option to qpdf to specify page rotation from
|
|
the command line.
|
|
|
|
* Provide --verbose option that causes qpdf to print an indication
|
|
of what files it is writing.
|
|
|
|
* Change --single-pages to --split-pages and make it take an
|
|
optional argument specifying the number of pages per file.
|
|
|
|
2017-08-11 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Fix --newline-before-endstream to always add a newline before
|
|
endstream even if the last character was already a newline. This
|
|
is actually what's required by PDF/A. Fixes #133.
|
|
|
|
* Handle encrypted files whose encryption parameters are too
|
|
short. Fixes #96.
|
|
|
|
2017-08-10 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Remove dependency on libpcre.
|
|
|
|
* Be more forgiving of certain types of errors in the xref table
|
|
that don't interfere with interpreting the table.
|
|
|
|
* Remove unused "tracing" parameter from PointerHolder's
|
|
(T*, bool) constructor. This change breaks source code
|
|
compatibility, but since this argument to PointerHolder has not
|
|
used for a long time and the presence of a boolean parameter in
|
|
the primary constructor makes it too easy to use that by mistake
|
|
when trying to use PointerHolder for arrays, it seems like it's
|
|
finally time to take it out. If you have a compile error because
|
|
of this change, please check to see whether you intended to use
|
|
the (bool, T*) version of the constructor instead. If not, just
|
|
remove the second parameter.
|
|
|
|
2017-08-09 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* When recovering stream length, find endobj without endstream as
|
|
well as just looking for endstream. Be a little more lax about
|
|
where we allow it to be found.
|
|
|
|
2017-08-05 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Add --single-pages option to cause output to be written to a
|
|
separate file for each page rather than one big file.
|
|
|
|
* Process --pages options earlier so that certain inspection
|
|
options, like --show-pages, can show the state after the merging
|
|
operations.
|
|
|
|
2017-08-02 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Fix off-by-one error in parsing pages options. Fixes #129.
|
|
|
|
2017-07-29 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Support @filename and @- in the qpdf command-line tool to read
|
|
command-line arguments, one per line, from the named file. @-
|
|
reads from standard input. Fixes #16.
|
|
|
|
* Detect when input file and output file are the same and exit to
|
|
avoid overwriting and losing input file. Fixes #29.
|
|
|
|
* When passing multiple inspection arguments, run --check first,
|
|
and defer exit until after all the checks have been run. This
|
|
makes it possible to force operations such as --show-xref to be
|
|
delayed until after recovery attempts have been made. For example,
|
|
if you have a file with a syntactically valid xref table that has
|
|
some offsets that are incorrect, running qpdf --check --show-xref
|
|
on that file will first recover the xref and the dump the
|
|
recovered xref, while just running qpdf --show-xref will show the
|
|
xref table as present in the file. Fixes #42.
|
|
|
|
* When recovering stream length, indicate the recovered length.
|
|
Fixes #44.
|
|
|
|
* Add --newline-before-endstream command-line option and
|
|
setNewlineBeforeEndstream method to QPDFWriter. This forces qpdf
|
|
to always add a newline before the endstream keyword. It is a
|
|
necessary but not sufficient condition for PDF/A compliance. Fixes
|
|
#103.
|
|
|
|
* Handle zlib data errors when decoding streams. Fixes #106.
|
|
|
|
* Improve handling of files where the "stream" keyword is not
|
|
followed by proper line terminators. Fixes #104.
|
|
|
|
* Fix content stream parsing to handle cases of structures within
|
|
the stream split across stream boundaries. Fixes #73.
|
|

|
|
|
|
* Add --preserve-unreferenced command-line option and
|
|
setPreserveUnreferencedObjects method to QPDFWriter. This option
|
|
causes QPDFWriter to write all objects from the input file to the
|
|
output file regardless of whether the objects are referenced.
|
|
Objects are written to the output file in numerical order from the
|
|
input file. This option has no effect for linearized files.
|
|
|
|
2017-07-27 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Add --precheck-streams command-line option and setStreamPrecheck
|
|
method to QPDFWriter to tell QPDFWriter to attempt decoding a
|
|
stream fully before deciding whether to filter it or not.
|
|
|
|
* Recover gracefully from streams that aren't filterable because
|
|
the filter parameters are invalid in the stream dictionary or the
|
|
dictionary itself is invalid.
|
|
|
|
* Significantly improve recoverability from invalid qpdf objects.
|
|
Most conditions in basic object parsing that used to cause qpdf to
|
|
exit are now warnings. There are still many more opportunities for
|
|
improvements of this sort beyond just object parsing.
|
|
|
|
2017-07-26 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Fixes to infinite loops below also fix problems reported in
|
|
other issues and cover CVE-2017-11624, CVE-2017-11625,
|
|
CVE-2017-11626, and CVE-2017-11627.
|
|
|
|
* Don't attempt to interpret syntactic keywords (like R and
|
|
endobj) found while parsing content streams.
|
|
|
|
* Detect infinite loops while resolving objects. This could happen
|
|
if something inside an object that had to be resolved during
|
|
parsing, such as a stream length, recursively referenced the
|
|
object being resolved.
|
|
|
|
* CVE-2017-9208: Handle references to and appearance of object 0
|
|
as a special case. Object 0 is not allowed, and qpdf was using it
|
|
internally to represent direct objects.
|
|
|
|
* CVE-2017-9209: Fix infinite loop caused by attempting to
|
|
reconstruct the xref table while already in the process of
|
|
reconstructing the xref table.
|
|
|
|
* CVE-2017-9210: Fix infinite loop caused by attempting to unparse
|
|
an object for inclusion in the text of an exception.
|
|
|
|
2015-11-10 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* 6.0.0: release
|
|
|
|
* No changes from 5.2.0. The 5.2.0 release broke binary
|
|
compatibility and was withdrawn.
|
|
|
|
2015-10-31 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* 5.2.0: release
|
|
|
|
* libqpdf/QPDF.cc (read_xrefTable): Be tolerant of some malformed
|
|
xref tables that don't have the required trailing space after each
|
|
line.
|
|
|
|
2015-10-29 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Implement QPDFWriter::setDeterministicID and --deterministic-id
|
|
command-line flag to qpdf to request generation of a deterministic
|
|
/ID for non-encrypted files.
|
|
|
|
2015-05-24 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* 5.1.3: release
|
|
|
|
* Bug fix: fix-qdf was not handling object streams with more than
|
|
255 objects in them.
|
|
|
|
* Handle Microsoft crypt provider initialization properly for case
|
|
where no keys have been previously created, such as in a fresh
|
|
Windows installation.
|
|
|
|
* Include time.h in QUtil.hh for time_t
|
|
|
|
2015-02-21 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Detect loops in Pages structure. Thanks to Gynvael Coldwind and
|
|
Mateusz Jurczyk of the Google Security Team for providing a sample
|
|
file with this problem.
|
|
|
|
* Prevent buffer overrun when converting a password to an
|
|
encryption key. Thanks to Gynvael Coldwind and Mateusz Jurczyk of
|
|
the Google Security Team for providing a sample file with this
|
|
problem.
|
|
|
|
* Ensure that arguments to "R" when parsing the file are direct
|
|
objects before trying to resolve them. This prevents specially
|
|
crafted files from causing qpdf to crash with a stack overflow.
|
|

|
|
|
|
* Some broken PDF files lack the required /Type key for /Page and
|
|
/Pages nodes in the page dictionary. QPDF now uses other methods
|
|
to figure out what kind of node it is looking at so that it can
|
|
handle those files. Original reported at
|
|
https://bugs.launchpad.net/ubuntu/+source/qpdf/+bug/1397413
|
|
|
|
2014-11-14 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Bug fix: QPDFObjectHandle::getPageContents() no longer throws an
|
|
exception when called on a page that has no /Contents key in its
|
|
dictionary. This is allowed by the spec, and some software
|
|
packages generate files like this for pages that are blank in the
|
|
original.
|
|
|
|
2014-06-07 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* 5.1.2: release
|
|
|
|
* MS Visual C++ build: explicitly target Windows 5.0.1 (XP)
|
|
|
|
* New example program: pdf-split-pages: efficiently split PDF
|
|
files into individual pages.
|
|
|
|
* Bug fix: don't fail on files that contain streams where /Filter
|
|
or /DecodeParms references a stream. Before, qpdf would try to
|
|
convert these to direct objects, which would fail because of the
|
|
stream.
|
|
|
|
2014-02-22 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Bug fix: if the last object in the first part of a linearized
|
|
file had an offset that was below 65536 by less than the size of
|
|
the hint stream, the xref stream was invalid and the resulting file
|
|
is not usable. This is now fixed.
|
|
|
|
2014-01-14 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* 5.1.1: release
|
|
|
|
2013-12-26 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Bug fix: when copying foreign objects (which occurs during page
|
|
splitting among other cases), avoid traversing the same object
|
|
more than once if it appears more than once in the same direct
|
|
object. This bug is performance-only and does not affect the
|
|
actual output.
|
|
|
|
2013-12-17 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* 5.1.0: release
|
|
|
|
2013-12-16 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Document and make explicit that passing null to
|
|
QUtil::setRandomDataProvider() resets the random data provider.
|
|
|
|
* Provide QUtil::getRandomDataProvider().
|
|
|
|
2013-12-14 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Allow any space rather than just newline to follow xref header.
|
|
This allows qpdf to read a wider range of damaged files.
|
|
|
|
2013-11-30 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Allow user-supplied random data provider to be used in place of
|
|
OS-provided or insecure random number generation. See
|
|
documentation for 5.1.0 for details.
|
|
|
|
* Add configure option --enable-os-secure-random (enabled by
|
|
default). Pass --disable-os-secure-random or define
|
|
SKIP_OS_SECURE_RANDOM to avoid attempts to use the operating
|
|
system-provided secure random number generation. This can be
|
|
especially useful on Windows if you wish to avoid any dependency
|
|
on Microsoft's cryptography system.
|
|
|
|
2013-11-29 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* If NO_GET_ENVIRONMENT is #defined, for Windows only,
|
|
QUtil::get_env will always return false. This was added to
|
|
support a user who needs to avoid calling GetEnvironmentVariable
|
|
from the Windows API. QUtil::get_env is not used for any
|
|
functionality in qpdf and exists only to support the test suite
|
|
including test coverage support with QTC (part of qtest).
|
|
|
|
* Add /FS to msvc builds to allow parallel builds to work with
|
|
Visual C++ 2013.
|
|
|
|
* Add missing #include <algorithm> in some files that use std::min
|
|
and std::max.
|
|
|
|
2013-11-21 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Change image comparison tests, which are disabled by default, to
|
|
use tiff files with 8 bits per sample rather than 4. This works
|
|
around a bug in tiffcmp but also increases time and disk space for
|
|
image comparison tests.
|
|
|
|
2013-10-28 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Fix MacOS compilation errors by adding a missing #include
|
|
<string> in a header file.
|
|
|
|
2013-10-18 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* 5.0.1: release
|
|
|
|
* Warn when -accessibility=n is specified with a modern encryption
|
|
format (R > 3). Also, accept this flag (and ignore with warning)
|
|
with 256-bit encryption. qpdf has always ignored the
|
|
accessibility setting with R > 3, but it previously did so
|
|
silently.
|
|
|
|
2013-10-05 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Replace operator[] in std::string and std::vector with "at" in
|
|
order to get bounds checking. This reduces the chances that
|
|
incorrect code will result in data exposure or buffer overruns.
|
|
See README.hardening for additional notes.
|
|
|
|
* Use cryptographically secure random number generation when
|
|
available. See additional notes in README.
|
|
|
|
* Replace some assert() calls with std::logic_error exceptions.
|
|
Ideally there shouldn't be assert() calls outside of testing.
|
|
This change may make a few more potential code errors in handling
|
|
invalid data recoverable.
|
|
|
|
* Security fix: In places where std::vector<T>(size_t) was used,
|
|
either validate that the size parameter is sane or refactor code
|
|
to avoid the need to pre-allocate the vector. This reduces the
|
|
likelihood of allocating a lot of memory in response to invalid
|
|
data in linearization hint streams.
|
|
|
|
* Security fix: sanitize /W array in cross reference stream to
|
|
avoid a potential integer overflow in a multiplication. It is
|
|
unlikely that any exploits were possible from this bug as
|
|
additional checks were also performed.
|
|
|
|
* Security fix: avoid buffer overrun that could be caused by bogus
|
|
data in linearization hint streams. The incorrect code could only
|
|
be triggered when checking linearization data, which must be
|
|
invoked explicitly. qpdf does not check linearization data when
|
|
reading or writing linearized files, but the qpdf --check command
|
|
does check linearization data.
|
|
|
|
* Security fix: properly handle empty strings in
|
|
QPDF_Name::normalizeName. The empty string is not a valid name
|
|
and would never be parsed as a name, so there were no known
|
|
conditions where this method could be called with an empty string.
|
|
|
|
* Security fix: perform additional argument sanity checks when
|
|
reading bit streams.
|
|
|
|
* Security fix: in QUtil::toUTF8, change bounds checking to avoid
|
|
having a pointer point temporarily outside the bounds of an
|
|
array. Some compiler optimizations could have made the original
|
|
code unsafe.
|
|
|
|
2013-07-10 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* 5.0.0: release
|
|
|
|
* 4.2.0 turned out to be binary incompatible on some platforms
|
|
even though there were no changes to the public API. Therefore
|
|
the 4.2.0 release has been withdrawn, and is being replaced with a
|
|
5.0.0 release that acknowledges the ABI change and also removes
|
|
some problematic methods from the public API.
|
|
|
|
* Remove methods from public API that were only intended to be
|
|
used by QPDFWriter and really didn't make sense to call from
|
|
anywhere else as they required internal knowledge that only
|
|
QPDFWriter had:
|
|
- QPDF::getLinearizedParts
|
|
- QPDF::generateHintStream
|
|
- QPDF::getObjectStreamData
|
|
- QPDF::getCompressibleObjGens
|
|
- QPDF::getCompressibleObjects
|
|
|
|
2013-07-07 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* 4.2.0: release [withdrawn]
|
|
|
|
* Ignore error case of a stream's decode parameters having invalid
|
|
length when there are no stream filters.
|
|
|
|
* qpdf: add --show-npages command-line option, which causes the
|
|
number of pages in the input file to be printed on a line by
|
|
itself.
|
|
|
|
* qpdf: allow omission of range in --pages. If range is omitted
|
|
such that an argument that is supposed to be a range is an invalid
|
|
range and a valid file name, the range of 1-z is assumed. This
|
|
makes it possible to merge a bunch of files with something like
|
|
qpdf --empty out.pdf --pages *.pdf --
|
|
|
|
2013-06-15 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Handle some additional broken files with missing /ID in trailer
|
|
for encrypted files and with space rather than newline after xref.
|
|
|
|
2013-06-14 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Detect and correct /Outlines dictionary being a direct object
|
|
when linearizing files. This is not allowed by the spec but has
|
|
been seen in the wild. Prior to this change, such a file would
|
|
cause an internal error in the linearization code, which assumed
|
|
/Outlines was indirect.
|
|
|
|
* Add /Length key to crypt filter dictionary for encrypted files.
|
|
This key is optional, but some version of MacOS reportedly fail to
|
|
open encrypted PDF files without this key.
|
|
|
|
* Bug fix: properly handle object stream generation when the
|
|
original file has some compressible objects with generation != 0.
|
|
|
|
* Add QPDF::getCompressibleObjGens() and deprecate
|
|
QPDF::getCompressibleObjects(), which had a flaw in its logic.
|
|
|
|
* Add new QPDFObjectHandle::getObjGen() method and indicate in
|
|
comments that its use is favored over getObjectID() and
|
|
getGeneration() for most cases.
|
|
|
|
* Add new QPDFObjGen object to represent an object ID/generation
|
|
pair.
|
|
|
|
2013-04-14 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* 4.1.0: release
|
|
|
|
2013-03-25 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* manual/qpdf-manual.xml: Document the casting policy that is
|
|
followed in qpdf's implementation.
|
|
|
|
2013-03-11 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* When creating Windows binary distributions, make sure to only
|
|
copy DLLs of the correct type. The ensures that the 32-bit
|
|
distributions contain 32-bit DLLs and the 64-bit distributions
|
|
contain 64-bit DLLs.
|
|
|
|
2013-03-07 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Use ./install-sh (already present) instead of "install -c" to
|
|
install executables to fix portability problems against different
|
|
UNIX variants.
|
|
|
|
2013-03-03 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Add protected terminateParsing method to
|
|
QPDFObjectHandle::ParserCallbacks that implementor can call to
|
|
terminate parsing of a content stream.
|
|
|
|
2013-02-28 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Favor fopen_s and strerror_s on MSVC to avoid CRT security
|
|
warnings. This is useful for people who may want to use qpdf in
|
|
an application that is Windows 8 certified.
|
|
|
|
* New method QUtil::safe_fopen to wrap calls to fopen. This is
|
|
less cumbersome than calling QUtil::fopen_wrapper.
|
|
|
|
* Remove all calls to sprintf
|
|
|
|
* New method QUtil::int_to_string_base to convert to octal or
|
|
hexadecimal (or decimal) strings without using sprintf
|
|
|
|
2013-02-26 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Rewrite QUtil::int_to_string and QUtil::double_to_string to
|
|
remove internal length limits but to remain backward compatible
|
|
with the old versions for valid inputs.
|
|
|
|
2013-02-23 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Bug fix: properly handle overridden compressed objects. When
|
|
caching objects from an object stream, only cache objects that,
|
|
based on the xref table, would actually be resolved into this
|
|
stream. Prior to this fix, if an object stream A contained an
|
|
object B that was overridden by an appended section of the file,
|
|
qpdf would cache the old value of B if any non-overridden member
|
|
of A was accessed before B. This commit fixes that bug.
|
|
|
|
2013-01-31 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Do not remove libtool's .la file during the make install step.
|
|
Note to packagers: if your distribution wants to you remove the
|
|
.la file, you will have to do that yourself now.
|
|
|
|
2013-01-25 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* New method QUtil::hex_encode to encode binary data as a
|
|
hexadecimal string
|
|
|
|
* qpdf --check was exiting with status 0 in some rare cases even
|
|
when errors were found. It now always exits with one of the
|
|
document error codes (0 for success, 2 for errors, 3 or warnings).
|
|
|
|
2013-01-24 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Make --enable-werror work for MSVC, and generally handle warning
|
|
options better for that compiler. Warning flags for that compiler
|
|
were previous hard-coded into the build with /WX enabled
|
|
unconditionally.
|
|
|
|
* Split warning flags into WFLAGS in autoconf.mk to make them
|
|
easier to override. Before they were repeated in CFLAGS and
|
|
CXXFLAGS and were commingled with other compiler flags.
|
|
|
|
* qpdf --check now does syntactic checks all pages' content
|
|
streams as well as checking overall document structure. Semantic
|
|
errors are still not checked, and there are no plans to add
|
|
semantic checks.
|
|
|
|
2013-01-22 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Add QPDFObjectHandle::getTypeCode(). This method returns a
|
|
unique integer (enumerated type) value corresponding to the object
|
|
type of the QPDFObjectHandle. It can be used as an alternative to
|
|
the QPDFObjectHandle::is* methods for type testing, particularly
|
|
where there is a desire to use a switch statement or optimize for
|
|
performance when testing object types.
|
|
|
|
* Add QPDFObjectHandle::getTypeName(). This method returns a
|
|
string literal describing the object type. It is useful for
|
|
testing and debugging.
|
|
|
|
2013-01-20 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Add QPDFObjectHandle::parseContentStream, which parses the
|
|
objects in a content stream and calls handlers in a callback
|
|
class. The example pdf-parse-content illustrates it use.
|
|
|
|
* Add QPDF_Operator and QPDF_InlineImage types along with
|
|
appropriate wrapper methods in QPDFObjectHandle. These new object
|
|
types are to facilitate content stream parsing.
|
|
|
|
2013-01-17 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* 4.0.1: release
|
|
|
|
* Add clarifying comment in QPDF.hh for methods that return the
|
|
user password to state that it is no longer possible with newer
|
|
encryption formats to recover the user password knowing the owner
|
|
password.
|
|
|
|
* Fix detection of binary attachments in the test suite. This
|
|
resolves false test failures on some platforms. No changes to the
|
|
actual QPDF code were made.
|
|
|
|
2012-12-31 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* 4.0.0: release
|
|
|
|
* Add new methods qpdf_get_pdf_extension_level,
|
|
qpdf_set_r5_encryption_parameters,
|
|
qpdf_set_r6_encryption_parameters,
|
|
qpdf_set_minimum_pdf_version_and_extension, and
|
|
qpdf_force_pdf_version_and_extension to support new functionality
|
|
from the C API.
|
|
|
|
2012-12-30 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Fix long-standing bug that could theoretically have resulted in
|
|
possible misinterpretation of decode parameters in streams. As
|
|
far as I can tell, it is extremely unlikely that files with the
|
|
characteristics that would have triggered the bug actually exist
|
|
in cases that qpdf versions prior to 4.0.0 could have read.
|
|
Unencrypted files with encrypted attachments would have triggered
|
|
this bug, but qpdf versions prior to 4.0.0 already refused to open
|
|
such files.
|
|
|
|
* Fix long-standing bug in which a stream that used a crypt
|
|
filter and was otherwise not filterable by qpdf would be decrypted
|
|
properly but would retain the crypt filter indication in the
|
|
file. There are no known ways to create files like this, so it is
|
|
unlikely that anyone ever hit this bug.
|
|
|
|

|
|
|
|
* Add read/write support for both the deprecated Acrobat IX
|
|
encryption format and the Acrobat X/PDF 2.0 encryption format
|
|
using 256-bit AES keys. Using the Acrobat IX format (R=5) forces
|
|
the version of the file to 1.7 with extension level 3. Using the
|
|
PDF 2.0 format (R=6) forces it to 1.7 extension level 8.
|
|
|
|
* Add new method QPDF::getEncryptionKey to return the actual
|
|
encryption key used for encryption of data in the file. The key
|
|
is returned as a std::string.
|
|
|
|
* Non-compatible API change: change signature of
|
|
QPDF::compute_data_key to take the R and V values from the
|
|
encryption dictionary. There is no reason for any application
|
|
code to call this method since handling of encryption is done
|
|
automatically by the qpdf library. It is used internally by
|
|
QPDFWriter.
|
|
|
|
* Support reading and decryption of files whose main text is not
|
|
encrypted but whose attachments are. More generally, support the
|
|
case of files and streams encrypted differently with some
|
|
limitations, described in the documentation. This was not
|
|
previously supported due to lack of test files, but I created test
|
|
files using a trial version of Acrobat XI to fully implement this
|
|
case.
|
|
|
|
* Incorporate sha2 code from sphlib 3.0. See README for
|
|
licensing. Create private pipeline class for computing hashes
|
|
with sha256, sha384, and sha512.
|
|
|
|
* Allow specification of initialization vector when using AES
|
|
filtering. This is required to compute the hash used in /R=6 (PDF
|
|
2.0) encryption.
|
|
|
|
2012-12-28 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Add random number generation functions to QUtil.
|
|
|
|
* Fix old bug that could cause an infinite loop if user password
|
|
recovery methods were called and a password contained the "("
|
|
character (which happens to be the first byte of padding used by
|
|
older PDF encryption formats). This bug was noticed while reading
|
|
code and would not happen under ordinary usage patterns even if
|
|
the password contained that character.
|
|
|
|
2012-12-27 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Add awareness of extension level to PDF Version methods for both
|
|
reading and writing. This includes adding method
|
|
QPDF::getExtensionLevel and new versions of
|
|
QPDFWriter::setMinimumPDFVersion and QPDFWriter::forcePDFVersion
|
|
that support extension levels. The qpdf command-line tool
|
|
interprets version numbers of the form x.y.z as version x.y at
|
|
extension level z.
|
|
|
|
* Update AES classes to support use of 256-bit keys.
|
|
|
|
* Non-compatible API change: Removed public method
|
|
QPDF::flattenScalarReferences. Instead, just flatten the scalar
|
|
references we actually need to flatten. Flattening scalar
|
|
references was a wrong decision years ago and has occasionally
|
|
caused other problems, among which were that it caused qpdf to
|
|
visit otherwise unreferenced and possibly erroneous objects in the
|
|
file when it didn't have to. There's no reason that any
|
|
non-internal code would have had to call this.
|
|
|
|
* Non-compatible API change: Removed public method
|
|
QPDF::decodeStreams which was previously used by qpdf --check but
|
|
is no longer used. The decodeStreams method could generate false
|
|
positives since it would attempt to access all objects in the file
|
|
including those that were not referenced. There's no reason that
|
|
any non-internal code would have had to call this.
|
|
|
|
* Non-compatible API change: Removed public method
|
|
QPDF::trimTrailerForWrite, which was only intended for use by
|
|
QPDFWriter and which is no longer used.
|
|
|
|
2012-12-26 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Add new fields to QPDF::EncryptionData to support newer
|
|
encryption formats (V=5, R=5 and R=6)
|
|
|
|
* Non-compatible API change: Change public nested class
|
|
QPDF::EncryptionData to make all member fields private and to add
|
|
method calls. This is a non-compatible API change, but changing
|
|
EncryptionData is necessary to support newer encryption formats,
|
|
and making this change will prevent the need from making a
|
|
non-compatible change in the future if new fields are added. A
|
|
public nested class should never have had public members to begin
|
|
with.
|
|
|
|
2012-12-25 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Allow PDF header to appear anywhere in the first 1024 bytes of
|
|
the file as recommended in the implementation notes of the Adobe
|
|
version of the PDF spec.
|
|
|
|
2012-11-20 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Add zlib and libpcre to Requires.private in the pkg-config file
|
|
to support static linking. Thanks Tobias Hoffmann for pointing
|
|
out the omission.
|
|
|
|
* Ignore (with warning) non-freed objects in the xref table whose
|
|
offset is 0. Some PDF producers (incorrectly) do this. See
|
|
https://bugs.linuxfoundation.org/show_bug.cgi?id=1081.
|
|
|
|
2012-09-23 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Add public methods QPDF::processInputSource and
|
|
QPDFWriter::setOutputPipeline to allow users to read from custom
|
|
input sources and to write to custom pipelines. This allows the
|
|
maximum flexibility in sources for reading and writing PDF files.
|
|
|
|
2012-09-06 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* 3.0.2: release
|
|
|
|
* Add new method QPDFWriter::setExtraHeaderText to add extra text,
|
|
such as application-specific comments, to near the beginning of a
|
|
PDF file. For linearized files, this appears after the
|
|
linearization parameter dictionary. For non-linearized files, it
|
|
appears right after the PDF header and non-ASCII comment.
|
|
|
|
* Make it possible to write the same QPDF object with two
|
|
different QPDFWriter objects that have both called
|
|
setLinearization(true) by making private method
|
|
QPDF::calculateLinearizationData() properly initialize its state.
|
|
|
|
* Bug fix: Writing after calling QPDFWriter::setOutputMemory()
|
|
would cause a segmentation fault because of an internal field not
|
|
being initialized, rendering that method useless. This has been
|
|
corrected.
|
|
|
|
2012-08-11 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* 3.0.1: release
|
|
|
|
* Bug fix: let EOF terminate a literal token as well as
|
|
whitespace or comments.
|
|
|
|
2012-07-31 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* 3.0.0: release
|
|
|
|
2012-07-29 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* 3.0.rc1: release
|
|
|
|
2012-07-25 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* From Tobias: add QPDFObjectHandle::replaceStreamData that takes
|
|
a std::string analogous to the QPDFObjectHandle::newStream that
|
|
takes a string that was added earlier.
|
|
|
|
2012-07-21 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Change configure to have image comparison tests disabled by
|
|
default. Update README and README.maintainer with information
|
|
about running them.
|
|
|
|
* Add --pages command-line option to qpdf to enable page-based
|
|
merging and splitting.
|
|
|
|
* Add new method QPDFObjectHandle::replaceDict to replace a
|
|
stream's dictionary. Use with caution; see comments in
|
|
QPDFObjectHandle.hh.
|
|
|
|
* Add new method QPDFObjectHandle::parse for creation of
|
|
QPDFObjectHandle objects from string representations of the
|
|
objects. Thanks to Tobias Hoffmann for the idea.
|
|
|
|
2012-07-15 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* add new QPDF::isEncrypted method that returns some additional
|
|
information beyond other versions.
|
|
|
|
* libqpdf/QPDFWriter.cc: fix copyEncryptionParameters to fix the
|
|
minimum PDF version based on other file's encryption needs. This
|
|
is a fix to code added on 2012-07-14 and did not impact previously
|
|
released code.
|
|
|
|
* libqpdf/QPDFWriter.cc (copyEncryptionParameters): Bug fix: qpdf
|
|
was not preserving whether or not AES encryption was being used
|
|
when copying encryption parameters. The file would still have
|
|
been properly encrypted, but a file that started off encrypted
|
|
with AES could have become encrypted with RC4.
|
|
|
|
2012-07-14 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* QPDFWriter: add public copyEncryptionParameters to allow copying
|
|
encryption parameters from another file.
|
|
|
|
* QPDFWriter: detect if the user has inserted an indirect object
|
|
from another QPDF object and throw an exception directing the user
|
|
to copyForeignObject.
|
|
|
|
2012-07-11 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Added new APIs to copy objects from one QPDF to another. This
|
|
includes letting QPDF::addPage() (and QPDF::addPageAt()) accept a
|
|
page object from another QPDF and adding
|
|
QPDF::copyForeignObject(). See QPDF.hh for details.
|
|
|
|
* Add method QPDFObjectHandle::getOwningQPDF() to return the QPDF
|
|
object associated with an indirect QPDFObjectHandle.
|
|
|
|
* Add convenience methods to QPDFObjectHandle: assertIndirect(),
|
|
isPageObject(), isPagesObject()
|
|
|
|
* Cache when QPDF::pushInheritedAttributesToPage() has been called
|
|
to avoid traversing the pages trees multiple times. This state is
|
|
cleared by QPDF::updateAllPagesCache() and ignored by
|
|
QPDF::flattenPagesTree().
|
|
|
|
2012-07-08 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Add QPDFObjectHandle::newReserved to create a reserved object
|
|
and QPDF::replaceReserved to replace it with a real object.
|
|
QPDFObjectHandle::newReserved reserves an object ID in a QPDF
|
|
object and ensures that any references to it remain unresolved.
|
|
When QPDF::replaceReserved is later called, previous references to
|
|
the reserved object will properly resolve to the replaced object.
|
|
|
|
2012-07-07 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* NOTE: BREAKING API CHANGE. Remove previously required length
|
|
parameter from the version QPDFObjectHandle::replaceStreamData
|
|
that uses a stream data provider. Prior to qpdf 3.0.0, you had to
|
|
compute the stream length in advance so that qpdf could internally
|
|
verify that the stream data had the same length every time the
|
|
provider was invoked. Now this requirement is enforced a
|
|
different way, and the length parameter is no longer required.
|
|
Note that I take API-breaking changes very seriously and only did
|
|
it in this case since the lack of need to know length in advance
|
|
could significantly simplify people's code. If you were
|
|
previously going to a lot of trouble to compute the length of the
|
|
new stream data in advance, you now no longer have to do that.
|
|
You can just drop the length parameter and remove any code that
|
|
was previously computing the length. Thanks to Tobias Hoffmann
|
|
for pointing out how annoying the original interface was.
|
|
|
|
2012-07-05 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Add QPDFWriter methods to write to an already open stdio FILE*.
|
|
Implementation and idea area based on contributions from Tobias
|
|
Hoffmann.
|
|
|
|
2012-07-04 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Accept changes from Tobias Hoffmann: add public method
|
|
QPDF::pushInheritedAttributesToPage including warnings for
|
|
non-inherited keys that may be discarded from /Pages by
|
|
non-conformant PDF files when the /Pages tree is flattened.
|
|
|
|
2012-06-27 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Add Pl_Concatenate pipeline for stream concatenation also
|
|
implemented by Tobias Hoffmann. Also added test code
|
|
(libtests/concatenate.cc).
|
|
|
|
* Add new methods implemented by Tobias Hoffmann:
|
|
QPDFObjectHandle::newReal(double) and
|
|
QPDFObjectHandle::newStream(QPDF*, std::string const&).
|
|
|
|
2012-06-26 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Minor changes so that support for PDF files larger than 4GB
|
|
works well with 32-bit and 64-bit Linux and also with 32-bit and
|
|
64-bit Windows with both MSVC and mingw.
|
|
|
|
* Rework internal methods for doing recovery of the cross
|
|
reference tables for much greater efficiency both in terms of time
|
|
and memory usage.
|
|
|
|
2012-06-24 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Support PDF files larger than 4 GB. This involved many changes
|
|
to the ABI to increase the size of integer types used in various
|
|
places as well as increasing the amount of padding used when
|
|
creating linearized files. Automated tests for large files are
|
|
disabled by default. Run ./configure --help for information on
|
|
enabling them. Running the tests requires 11 GB of free disk
|
|
space and takes several minutes.
|
|
|
|
2012-06-22 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* examples/pdf-create.cc: Provide an example of creating a PDF
|
|
from scratch. This simple PDF has a single page with some text
|
|
and an image.
|
|
|
|
* Add empty QPDFObjectHandle factories for array and dictionary.
|
|
With PDF-from-scratch capability, it is useful to be able to
|
|
create empty arrays and dictionaries and add keys to them.
|
|
Updated pdf_from_scratch.cc to use these interfaces.
|
|
|
|
2012-06-21 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Add QPDF::emptyPDF() to create an empty QPDF object suitable for
|
|
adding pages and other objects to. pdf_from_scratch.cc is test
|
|
code that exercises it.
|
|
|
|
* make/libtool.mk: Place user-specified CPPFLAGS and LDFLAGS later
|
|
in the compilation so that if a user installs things in a
|
|
non-standard place that they have to tell the build about, earlier
|
|
versions of qpdf installed there won't break the build. Thanks to
|
|
Macports for reporting this. (Fixes bug 3468860.)
|
|
|
|
* Instead of using off_t in the public APIs, use qpdf_offset_t
|
|
instead. This is defined as long long in qpdf/Types.h. If your
|
|
system doesn't support long long, you can redefine it.
|
|
|
|
* Add pkg-config files
|
|
|
|
* QPDFObjectHandle: add shallowCopy() method
|
|
|
|
* QPDF: add new APIs for adding and removing pages. This includes
|
|
addPage(), addPageAt(), and removePage(). Also a method
|
|
updateAllPagesCache() is now available to force update of the
|
|
internal pages cache if you should modify the pages structure
|
|
manually.
|
|
|
|
* QPDF: new processFile method that takes an open FILE*
|
|
instead of a filename.
|
|
|
|
2012-06-20 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Add new array mutation routines to QPDFObjectHandle.
|
|
Implemented by Tobias Hoffmann.
|
|
|
|
* Rework APIs that use size_t, off_t, and primitive integer types
|
|
so that size_t is used for sizes of memory and off_t is used for
|
|
file offsets. Also set _FILE_OFFSET_BITS so that large files can
|
|
be supported on 32-bit UNIX/Linux platforms. The code assumes in
|
|
places that sizeof(off_t) >= sizeof(size_t). This resulted in
|
|
non-compatible ABI changes and hopefully clears the way for QPDF
|
|
to work with files that are larger than 4 GiB in size.
|
|
|
|
* Add support for versioned symbols on ELF platforms.
|
|
|
|
* Various fixes for gcc 4.7
|
|
|
|
2011-04-06 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Fix PCRE to stop using deprecated (and now dropped) interfaces.
|
|
|
|
2011-12-28 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* 2.3.1: release
|
|
|
|
* include <stdint.h> if available to support MSVC 2010
|
|
|
|
* Since PCRE is not necessarily thread safe, don't declare any
|
|
PCRE objects to be static.
|
|
|
|
* Disregard stderr output from ghostscript when using it to
|
|
compare images in the test suite; see comments in qpdf.test for
|
|
details.
|
|
|
|
* Fixed a few documentation errors.
|
|
|
|
2011-08-11 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* 2.3.0: release
|
|
|
|
* include/qpdf/qpdf-c.h ("C"): add new methods
|
|
qpdf_init_write_memory, qpdf_get_buffer_length, and
|
|
qpdf_get_buffer to support writing to memory from the C API.
|
|
|
|
* include/qpdf/qpdf-c.h ("C"): add new methods qpdf_get_info_key
|
|
and qpdf_set_info_key for manipulating text fields of the /Info
|
|
dictionary.
|
|
|
|
2011-08-10 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* libqpdf/QPDFWriter.cc (copyEncryptionParameters): preserve
|
|
whether metadata is encryption. This fixes part of bug 3173659:
|
|
the password becomes invalid if qpdf copies an encrypted file with
|
|
cleartext-metadata.
|
|
|
|
* include/qpdf/QPDFWriter.hh: add a new constructor that takes
|
|
only a QPDF reference and leaves specification of output for
|
|
later. Add methods setOutputFilename() to set the output to a
|
|
filename or stdout, and setOutputMemory() to indicate that output
|
|
should go to a memory buffer. Add method getBuffer() to retrieve
|
|
the buffer used if output was saved to a memory buffer.
|
|
|
|
* include/qpdf/QPDF.hh: add methods replaceObject() and
|
|
swapObjects() to allow replacement of an object and swapping of
|
|
two objects by object ID.
|
|
|
|
* include/qpdf/QPDFObjectHandle.hh: add new methods getDictAsMap()
|
|
and getArrayAsVector() for returning the elements of a dictionary
|
|
or an array as a map or vector.
|
|
|
|
2011-06-25 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* 2.2.4: release
|
|
|
|
2011-06-23 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* make/libtool.mk (install): Do not strip executables and shared
|
|
libraries during installation. Leave that up to the packager.
|
|
|
|
* configure.ac: disable -Werror by default.
|
|
|
|
2011-05-07 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* libqpdf/QPDF_linearization.cc (isLinearized): remove unused
|
|
offset variable, found by a gcc 4.6 warning.
|
|
|
|
2011-04-30 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* 2.2.3: release
|
|
|
|
* libqpdf/QPDF.cc (readObjectInternal): Accept the case of the
|
|
stream keyword being followed by carriage return by itself. While
|
|
this is not permitted by the specification, there are PDF files
|
|
that do this, and other readers can read them.
|
|
|
|
* libqpdf/Pl_QPDFTokenizer.cc (processChar): When an inline image
|
|
is detected, suspend normalization only up to the end of the
|
|
inline image rather than for the remainder of the content stream.
|
|
(Fixes qpdf-Bugs 3152169.)
|
|
|
|
2011-01-31 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* libqpdf/QPDF.cc (readObjectAtOffset): use -1 rather than 0 when
|
|
reading an object at a given to indicate that no object number is
|
|
expected. This allows xref recovery to proceed even if a file
|
|
uses the invalid object number 0 as a regular object.
|
|
|
|
* libqpdf/QPDF_linearization.cc (isLinearized): use -1 rather than
|
|
0 as a sentinel for not having found the first object in the
|
|
file. Since -1 can never match the regular expression, this
|
|
prevents an infinite loop when checking a file that starts with
|
|
(erroneous) 0 0 obj. (Fixes qpdf-Bugs-3159950.)
|
|
|
|
2010-10-04 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* 2.2.2: release
|
|
|
|
* include/qpdf/qpdf-c.h: Add qpdf_read_memory to C API to call
|
|
QPDF::processMemoryFile.
|
|
|
|
2010-10-01 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* 2.2.1: release
|
|
|
|
* include/qpdf/QPDF.hh: Add setOutputStreams method to allow
|
|
redirection of library-generated output/error to alternative
|
|
streams.
|
|
|
|
* include/qpdf/QPDF.hh: Add processMemoryFile method for
|
|
processing a PDF file from a memory buffer instead of a file.
|
|
|
|
2010-09-24 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* libqpdf/QPDF.cc: change private "file" method to be a
|
|
PointerHolder<InputSource> to prepare qpdf for being able to work
|
|
with PDF files loaded into memory in addition to working with
|
|
files on disk.
|
|
|
|
* include/qpdf/PointerHolder.hh: add operator* and operator->
|
|
methods so that PointerHolder objects can be used like pointers.
|
|
This is consistent with the smart pointer objects in the next
|
|
revision of C++.
|
|

* libqpdf/QPDF.cc (readObjectInternal): Recognize empty objects
|
|
and treat them as null.
|
|
|
|
* libqpdf/QPDF_Stream.cc (filterable): Handle inline image filter
|
|
abbreviations as stream filter abbreviations. Although this is
|
|
not technically allowed by the PDF specification, table H.1 in the
|
|
pre-ISO spec indicates that Adobe's readers accept them. Thanks
|
|
to Jian Ma <stronghorse@tom.com> for bringing this to my
|
|
attention.

|
2010-08-14 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* 2.2.0: release
|
|
|
|
* Rename README.windows to README-windows.txt and convert its line
|
|
endings to Windows-style line endings. Also mention Jian Ma's VC6
|
|
port in the manual and README-windows.txt.
|
|
|
|
2010-08-09 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Add QPDFObjectHandle::getRawStreamData to return raw
|
|
(unfiltered) stream data.
|
|
|
|
2010-08-08 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* 2.2.rc1: release
|
|
|
|
2010-08-05 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Add QPDFObjectHandle::addPageContents, a convenience routine for
|
|
appending or prepending new streams to a page's content streams.
|
|
The "pdf-double-page-size" example illustrates its use.
|
|
|
|
* Add new methods to QPDFObjectHandle: replaceStreamData and
|
|
newStream. These methods allow users of the qpdf library to add
|
|
new streams and to replace data of existing streams. The
|
|
"pdf-double-page-size" and "pdf-invert-images" examples illustrate
|
|
their use.
|
|
|
|
2010-06-06 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Fix memory leak for QPDF objects whose underlying PDF objects
|
|
contain circular references. Thanks to Jian Ma
|
|
<stronghorse@tom.com> for calling my attention to the memory leak.
|
|
|
|
2010-04-25 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* 2.1.5: release
|
|
|
|
* libqpdf/QPDF_encryption.cc (compute_encryption_key): remove
|
|
restrictions on length of file identifier string. (Fixes
|
|
qpdf-Bugs-2991412.)
|
|
|
|
2010-04-18 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* 2.1.4: release
|
|
|
|
* libqpdf/QPDFWriter.cc (writeLinearized): the padding calculation
|
|
fix in 2.1.2 was applied in only one place but it was needed in
|
|
two places since there are actually two cross reference streams in
|
|
a linearized file. The new padding calculation is now used for
|
|
both streams. Hopefully this should put an end to linearization
|
|
padding problems. (Fixes qpdf-Bugs-2979219.)
|
|
|
|
2010-04-10 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* qpdf/qpdf.cc (main): Since qpdf --check only checks syntax and
|
|
stream encoding without doing any semantic checks, make the output
|
|
clearer when no errors around found. This is inspired by
|
|
qpdf-Bugs-2983225.
|
|
|
|
2010-03-27 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* 2.1.3: release
|
|
|
|
* libqpdf/QPDF_optimization.cc (flattenScalarReferences): Flatten
|
|
scalar references for unreferenced objects as well as those seen
|
|
during traversal of the file. This matters when preserving object
|
|
streams that contain unreferenced objects with indirect scalars.
|
|
(Fixes qpdf-Bugs-2974522.) Updated TODO with a description of a
|
|
possibly better fix involving removal of flattenScalarReferences.
|
|
|
|
* libqpdf/Pl_AES_PDF.cc (finish): Don't complain if an AES input
|
|
buffer is not a multiple of 16 bytes. Instead, just pad with
|
|
nulls and hope for the best. PDF files have been encountered "in
|
|
the wild" that contain AES buffers that aren't a multiple of 16
|
|
bytes.
|
|
|
|
2010-01-24 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* 2.1.2: release
|
|
|
|
* libqpdf/QPDFWriter.cc: fix logic error in padding calculation.
|
|
When writing linearized files with cross reference streams, the
|
|
padding calculation failed to take differences in sizes of
|
|
compressed data between pass 1 and pass 2 into consideration.
|
|
|
|
2009-12-14 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* 2.1.1: release
|
|
|
|
* qpdf/qtest/qpdf.test: improve test for acroread to make sure it
|
|
actually works and is not just present in the path.
|
|
|
|
2009-12-13 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* libqpdf/qpdf/Pl_AES_PDF.hh: include <stdint.h>, if available, so
|
|
we have valid definitions of uint32_t.
|
|
|
|
2009-10-30 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* 2.1: release
|
|
|
|
* libqpdf/QPDF.cc: be more forgiving of extraneous whitespace in
|
|
the xref table and while recovering from error conditions.
|
|
|
|
2009-10-26 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Work around failure of PCRE test case; this test case exercises
|
|
an aspect of PCRE that qpdf does not use, and the test fails with
|
|
the version of PCRE on Red Hat Enterprise Linux 5, so we ignore
|
|
failure on this particular test case.
|
|
|
|
* Fix RPM .spec file to include "C" examples
|
|
|
|
2009-10-24 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* 2.1.rc1: release
|
|
|
|
* Provide interfaces for getting qpdf's own version number
|
|
|
|
2009-10-19 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* include/qpdf/QPDF.hh (QPDF): getWarnings now returns a list of
|
|
QPDFExc rather than a list of strings. This way, warnings may be
|
|
inspected in more detail.
|
|
|
|
* Include information about the last object read in most error
|
|
messages. Most of the time, this will provide a good hint as to
|
|
which object contains the error, but it's possible that the last
|
|
object read may not necessarily be the one that has the error if
|
|
the erroneous object was previously read and cached.
|
|
|
|
2009-10-18 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* If forcing version, disable object stream creation and/or
|
|
encryption if previous specifications are incompatible with new
|
|
version. It is still possible that PDF content, compression
|
|
schemes, etc., may be incompatible with the new version, but at
|
|
least this way, older viewers will at least have a chance.
|
|
|
|
* libqpdf/QPDFWriter.cc (unparseObject): avoid compressing
|
|
Metadata streams if possible.
|
|
|
|
2009-10-13 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Upgrade embedded qtest to version 1.4, which allows the test
|
|
suite to be run in Windows with MSYS and ActiveState Perl rather
|
|
than requiring Cygwin perl.
|
|
|
|
2009-10-04 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Implement support AES encrypt and crypt filters. Implementation
|
|
is not fully tested due to lack of test data but has been tested
|
|
for several cases.
|
|
|
|
2009-10-04 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Add methods to QPDFWriter and corresponding command line
|
|
arguments to qpdf to set the minimum output PDF version and also
|
|
to force the version to a particular value.
|
|
|
|
* libqpdf/QPDF.cc (processXRefStream): warn and ignore extra xref
|
|
stream entries when stream is larger than reported size. This
|
|
used to be a fatal error. (Fixes qpdf-Bugs-2872265.)
|
|
|
|
2009-09-27 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Add several methods to query permissions controlled by the
|
|
encryption dictionary. Note that qpdf does not enforce these
|
|
permissions even though it allows the user to query them.
|
|
|
|
* The function QPDF::getUserPassword returned the user password
|
|
with the required padding as specified by the PDF specification.
|
|
This is seldom useful to users. This function has been replaced
|
|
by QPDF::getPaddedUserPassword. Call the new
|
|
QPDF::getTrimmedUserPassword to retrieve the user password in a
|
|
human-readable format.
|
|
|
|
* qpdf/qpdf.cc (main): qpdf --check now prints the PDF version
|
|
number in addition to its other output.
|
|
|
|
2009-09-26 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Removed all references to QEXC; now using std::runtime_error and
|
|
std::logic_error and their subclasses for all exceptions.
|
|
|
|
2009-05-03 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* 2.0.6: release
|
|
|
|
* libqpdf/QPDF_Stream.cc (filterable): ignore /DecodeParms if it's
|
|
not a type we recognize. (Fixes qpdf-Bugs-2779746.)
|
|
|
|
2009-03-10 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* 2.0.5: release
|
|
|
|
2009-03-09 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* libqpdf/Pl_LZWDecoder.cc: adjust LZWDecoder full table
|
|
detection, now having been able to adequately test boundary
|
|
conditions both and with and without early code change. Also
|
|
compared implementation with other LZW decoders.
|
|
|
|
2009-03-08 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* qpdf/fix-qdf (write_ostream): Adjust offsets while writing
|
|
object streams to account for changes in the length of the
|
|
dictionary and offset tables.
|
|
|
|
* qpdf/qpdf.cc (main): In check mode, in addition to checking
|
|
structure of file, attempt to decode all stream data.
|
|
|
|
* libqpdf/QPDFWriter.cc (QPDFWriter::writeObject): In QDF mode,
|
|
write a comment to the QDF file before each object that indicates
|
|
the object ID of the corresponding object from the original file.
|
|
Add --no-original-object-ids flag to qpdf and
|
|
setSuppressOriginalObjectIDs() method to QPDFWriter to turn this
|
|
behavior off.
|
|
|
|
* libqpdf/QPDF.cc (QPDF::pipeStreamData): Issue a warning instead
|
|
of failing if there is a problem found while decoding stream.
|
|
|
|
* qpdf/qpdf.cc: Exit with a status of 3 if warnings were found
|
|
regardless of what mode we're in.
|
|
|
|
2009-02-21 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* 2.0.4: release
|
|
|
|
2009-02-20 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Fix many typos in comments and strings.
|
|
|
|
* qpdf/qpdf.cc: in --check mode, if there are warnings but no
|
|
errors, exit with a status of 3.
|
|
|
|
* libqpdf/QPDF.cc (QPDF::insertXrefEntry): when recovering the
|
|
cross-reference table, have objects we encounter later in the file
|
|
supersede those we found earlier. This improves the chances of
|
|
being able to recover appended files with damaged cross-reference
|
|
tables.
|
|
|
|
2009-02-19 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* libqpdf/Pl_LZWDecoder.cc: correct logic error for previously
|
|
untested case of running the LZW decoder without the "early code
|
|
change" flag. Thanks to a bug report from "Atom Smasher", I
|
|
finally was able to obtain an input stream compressed in this way.
|
|
|
|
2009-02-15 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* 2.0.3: release
|
|
|
|
2008-12-11 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* qpdf/qpdf.cc (main): Accept -help and -version as well as --help
|
|
and --version
|
|
|
|
2008-11-23 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* Include stdio.h in a few files for proper compilation with (yet
|
|
to be released) gcc 4.4
|
|
|
|
* updated embedded qtest to version 1.3
|
|
|
|
* libqpdf/QPDF_String.cc (QPDF_String::getUTF8Val): handle
|
|
UTF-16BE properly rather than just treating the string as a string
|
|
of 16-bit characters.
|
|
|
|
2008-06-30 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* 2.0.2: release
|
|
|
|
* updated embedded qtest to version 1.2 (includes previous
|
|
changes)
|
|
|
|
2008-06-07 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* qpdf/qtest/qpdf/diff-encrypted: change == to = so that the test
|
|
suite passes when /bin/sh is not bash
|
|
|
|
2008-05-07 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* qtest/bin/qtest-driver (run_test): increase timeout for qtest to
|
|
be more tolerant of slow machines
|
|
|
|
2008-05-06 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* 2.0.1: release
|
|
|
|
* make/rules.mk: fix logic with .dep generation for .lo files so
|
|
that dependencies work properly with libtool
|
|
|
|
2008-05-05 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* libqpdf/qpdf/MD5.hh: fix header to be 64-bit clean
|
|
|
|
* configure.ac: add tests for sized integer types
|
|
|
|
2008-05-04 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* libqpdf/QPDF_encryption.cc: do not assume size_t is unsigned int
|
|
|
|
* qpdf/qtest/qpdf.test: removed locale-specific tests. These were
|
|
really to check bugs in perl 5.8.0 and are obsolete now. They
|
|
also make the test suite fail in some environments that don't have
|
|
all the locales fully configured.
|
|
|
|
* various: updated several files for gcc 4.3 by adding missing
|
|
includes (string.h, stdlib.h)
|
|
|
|
2008-04-26 Jay Berkenbilt <ejb@ql.org>
|
|
|
|
* 2.0: initial public release
|
