|
|
|
|
|
|
|
|
|
|
* 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 libary. 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.

|
|
|
|
|
|
|
|
|
|
* 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.

|
|
|
|
|
|
2012-12-31 01:59:38 +00:00
|
|
|
* 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 18:36:02 +00:00
|
|
|
* Add zlib and libpcre to Requires.private in the pkg-config file
|
|
|
|
|
to support static linking. Thanks Tobias Hoffmann for pointing
|
|
|
|
|
out the omission.
|
|
|
|
|
|
2012-11-20 18:15:14 +00:00
|
|
|
* 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.

|
|
|
* 3.0.2: release
|
|
|
|
|
|
2012-09-06 19:30:13 +00:00
|
|
|
* 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.
|
|
|
|
|
|
2012-09-06 19:28:16 +00:00
|
|
|
* 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.
|
|
|
|
|
|
2012-09-06 18:39:06 +00:00
|
|
|
* 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.

|
* From Tobias: add QPDFObjectHandle::replaceStreamData that takes
|
|
|
|
|
a std::string analogous to the QPDFObjectHandle::newStream that
|
|
|
|
|
takes a string that was added earlier.

|
|
|
|

2012-07-22 00:35:00 +00:00
|
|
|
* Change configure to have image comparison tests disabled by
|
|
|
|
|
default. Update README and README.maintainer with information
|
|
|
|
|
about running them.
|
|
|
|
|
|
2012-07-22 00:24:02 +00:00
|
|
|
* Add --pages command-line option to qpdf to enable page-based
|
|
|
|
|
merging and splitting.
|
|
|
|
|
|
2012-07-21 13:00:06 +00:00
|
|
|
* 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.

|
2012-07-16 01:15:24 +00:00
|
|
|
* 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.
|
|
|
|
|
|
2012-07-15 23:07:59 +00:00
|
|
|
* libqpdf/QPDFWriter.cc (copyEncryptionParameters): Bug fix: qpdf
|
|
|
|
|
was not preserving whether or not AES encryption was being used
|
2012-07-16 01:15:24 +00:00
|
|
|
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 13:13:49 +00:00
|
|
|
* QPDFWriter: add public copyEncryptionParameters to allow copying
|
|
|
|
|
encryption parameters from another file.
|
|
|
|
|
|
2012-07-14 12:07:23 +00:00
|
|
|
* 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().

|
|
|
|
|
|
|
|
|
|
* 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.

|
|
|
|
|
|
|
|
|
|
* 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.

|
|
|
|
|
(libtests/concatenate.cc).
|
|
|

|
|
QPDFObjectHandle::newReal(double) and
|
|
|
|
|
QPDFObjectHandle::newStream(QPDF*, std::string const&).

|
|

|
|
|
|
|
* 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.

|
|
|
|
|
|
|
|
|
|
* 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.

|
|
|
* 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.
|
|
|
|

|
2012-06-22 13:46:33 +00:00
|
|
|
* 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.

2012-06-22 03:06:48 +00:00
|
|
|
* 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.
|
|
|
|
|
|
2012-06-22 01:20:35 +00:00
|
|
|
* 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.)
|
|
|
|
|
|
2012-06-21 23:32:21 +00:00
|
|
|
* 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.
|
|
|
|
|
|
2012-06-21 20:40:31 +00:00
|
|
|
* Add pkg-config files
|
|
|
|
|
|
2012-06-21 20:14:34 +00:00
|
|
|
* QPDFObjectHandle: add shallowCopy() method
|
|
|
|
|
|
2012-06-21 19:28:58 +00:00
|
|
|
* 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*
|
2012-06-21 11:59:56 +00:00
|
|
|
instead of a filename.

* Add new array mutation routines to QPDFObjectHandle.
|
2012-06-21 14:55:02 +00:00
|
|
|
Implemented by Tobias Hoffmann.
|
2012-06-21 11:58:44 +00:00
|
|
|
|
|
|
|
|
* Rework APIs that use size_t, off_t, and primative 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

|
PCRE objects to be static.
|
|
|
|
|
|
|
|
|

|
* libqpdf/QPDFWriter.cc (copyEncryptionParameters): preserve
|

|
|
|
|
|
the password becomes invalid if qpdf copies an encrypted file with

|
|
|
|
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()

|
|
|
|
|
or an array as a map or vector.

this is not permitted by the specification, there are PDF files

* 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 sentintel 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.)

|
* 2.1.5: release
|
|
|
|
|
|
|
|
|
|
* libqpdf/QPDF_encryption.cc (compute_encryption_key): remove
|
|
|
|
|
restrictions on length of file identifier string. (Fixes
|
|
|
|
|
qpdf-Bugs-2991412.)

* 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.)

|
|
|
|
|
|
|
|
|
|
* 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 15:53:44 +00:00
|
|
|
* 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.

* 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.

|
|
* 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

2009-10-20 00:24:44 +00:00
|
|
|
* 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.
|
|
|
|
|
|
2009-10-19 23:09:19 +00:00
|
|
|
* 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.

|
|
|
* 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.
|

|
|
|
|
2009-10-18 14:09:10 +00:00

Metadata streams if possible.

|
|
|
|
|
|
|
|
|
* 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.

2009-10-05 00:42:48 +00:00
|
|
|
* 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.
|
|
|
|
|
|
2009-10-04 23:56:56 +00:00
|
|
|
* 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 20:05:38 +00:00
|
|
|
* 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.
|
|
|
|
|
|
2009-09-27 16:55:24 +00:00
|
|
|
* 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 retreive the user password in a
|
|
|
|
|
human-readable format.
|
|
|
|
|
|
|
|
|
|
* qpdf/qpdf.cc (main): qpdf --check now prints the PDF version
|

* 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.
