However, qpdf does not use automake, so not all of that file +applies. + +Basic Installation +================== + +Briefly, the shell commands `./configure; make; make install' should +configure, build, and install this package. The following +more-detailed instructions are generic; see the `README' file for +instructions specific to this package. + + The `configure' shell script attempts to guess correct values for +various system-dependent variables used during compilation. It uses +those values to create a `Makefile' in each directory of the package. +It may also create one or more `.h' files containing system-dependent +definitions. Finally, it creates a shell script `config.status' that +you can run in the future to recreate the current configuration, and a +file `config.log' containing compiler output (useful mainly for +debugging `configure'). + + It can also use an optional file (typically called `config.cache' +and enabled with `--cache-file=config.cache' or simply `-C') that saves +the results of its tests to speed up reconfiguring. Caching is +disabled by default to prevent problems with accidental use of stale +cache files. + + If you need to do unusual things to compile the package, please try +to figure out how `configure' could check whether to do them, and mail +diffs or instructions to the address given in the `README' so they can +be considered for the next release. If you are using the cache, and at +some point `config.cache' contains results you don't want to keep, you +may remove or edit it. + + The file `configure.ac' (or `configure.in') is used to create +`configure' by a program called `autoconf'. You need `configure.ac' if +you want to change it or regenerate `configure' using a newer version +of `autoconf'. + +The simplest way to compile this package is: + + 1. `cd' to the directory containing the package's source code and type + `./configure' to configure the package for your system. + + Running `configure' might take a while. While running, it prints + some messages telling which features it is checking for. + + 2. Type `make' to compile the package. + + 3. Optionally, type `make check' to run any self-tests that come with + the package. + + 4. Type `make install' to install the programs and any data files and + documentation. + + 5. You can remove the program binaries and object files from the + source code directory by typing `make clean'. To also remove the + files that `configure' created (so you can compile the package for + a different kind of computer), type `make distclean'. There is + also a `make maintainer-clean' target, but that is intended mainly + for the package's developers. If you use it, you may have to get + all sorts of other programs in order to regenerate files that came + with the distribution. + +Compilers and Options +===================== + +Some systems require unusual options for compilation or linking that the +`configure' script does not know about. Run `./configure --help' for +details on some of the pertinent environment variables. + + You can give `configure' initial values for configuration parameters +by setting variables in the command line or in the environment. Here +is an example: + + ./configure CC=c99 CFLAGS=-g LIBS=-lposix + +Installation Names +================== + +By default, `make install' installs the package's commands under +`/usr/local/bin', include files under `/usr/local/include', etc. You +can specify an installation prefix other than `/usr/local' by giving +`configure' the option `--prefix=PREFIX'. + + You can specify separate installation prefixes for +architecture-specific files and architecture-independent files. If you +pass the option `--exec-prefix=PREFIX' to `configure', the package uses +PREFIX as the prefix for installing programs and libraries. +Documentation and other data files still use the regular prefix. + + In addition, if you use an unusual directory layout you can give +options like `--bindir=DIR' to specify different values for particular +kinds of files. Run `configure --help' for a list of the directories +you can set and what kinds of files go in them. + + If the package supports it, you can cause programs to be installed +with an extra prefix or suffix on their names by giving `configure' the +option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'. + + You can also define the variable DESTDIR when you run make install +to install the package in a separate subdirectory. This is useful for +packaging. + +Optional Features +================= + +Some packages pay attention to `--enable-FEATURE' options to +`configure', where FEATURE indicates an optional part of the package. +They may also pay attention to `--with-PACKAGE' options, where PACKAGE +is something like `gnu-as' or `x' (for the X Window System). The +`README' should mention any `--enable-' and `--with-' options that the +package recognizes. + + For packages that use the X Window System, `configure' can usually +find the X include and library files automatically, but if it doesn't, +you can use the `configure' options `--x-includes=DIR' and +`--x-libraries=DIR' to specify their locations. + +Specifying the System Type +========================== + +There may be some features `configure' cannot figure out automatically, +but needs to determine by the type of machine the package will run on. +Usually, assuming the package is built to be run on the _same_ +architectures, `configure' can figure that out, but if it prints a +message saying it cannot guess the machine type, give it the +`--build=TYPE' option. TYPE can either be a short name for the system +type, such as `sun4', or a canonical name which has the form: + + CPU-COMPANY-SYSTEM + +where SYSTEM can have one of these forms: + + OS KERNEL-OS + + See the file `config.sub' for the possible values of each field. If +`config.sub' isn't included in this package, then this package doesn't +need to know the machine type. + + If you are _building_ compiler tools for cross-compiling, you should +use the option `--target=TYPE' to select the type of system they will +produce code for. + + If you want to _use_ a cross compiler, that generates code for a +platform different from the build platform, you should specify the +"host" platform (i.e., that on which the generated programs will +eventually be run) with `--host=TYPE'. + +Sharing Defaults +================ + +If you want to set default values for `configure' scripts to share, you +can create a site shell script called `config.site' that gives default +values for variables like `CC', `cache_file', and `prefix'. +`configure' looks for `PREFIX/share/config.site' if it exists, then +`PREFIX/etc/config.site' if it exists. Or, you can set the +`CONFIG_SITE' environment variable to the location of the site script. +A warning: not all `configure' scripts look for a site script. + +Defining Variables +================== + +Variables not defined in a site shell script can be set in the +environment passed to `configure'. However, some packages may run +configure again during the build, and the customized values of these +variables may be lost. In order to avoid this problem, you should set +them in the `configure' command line, using `VAR=value'. For example: + + ./configure CC=/usr/local2/bin/gcc + +causes the specified `gcc' to be used as the C compiler (unless it is +overridden in the site shell script). + +Unfortunately, this technique does not work for `CONFIG_SHELL' due to +an Autoconf bug. Until the bug is fixed you can use this workaround: + + CONFIG_SHELL=/bin/bash /bin/bash ./configure CONFIG_SHELL=/bin/bash + +`configure' Invocation +====================== + +`configure' recognizes the following options to control how it operates. + +`--help' +`-h' + Print a summary of the options to `configure', and exit. + +`--version' +`-V' + Print the version of Autoconf used to generate the `configure' + script, and exit. + +`--cache-file=FILE' + Enable the cache: use and save the results of the tests in FILE, + traditionally `config.cache'. FILE defaults to `/dev/null' to + disable caching. + +`--config-cache' +`-C' + Alias for `--cache-file=config.cache'. + +`--quiet' +`--silent' +`-q' + Do not print messages saying which checks are being made. To + suppress all normal output, redirect it to `/dev/null' (any error + messages will still be shown). + +`--srcdir=DIR' + Look for the package's source code in directory DIR. Usually + `configure' can determine that directory automatically. + +`configure' also accepts some other, not widely useful, options.

That code knows which objects +are used by which pages, though it doesn't do anything page-specific +with outlines, thumbnails, page labels, or anything else. + +Another approach would be to traverse only pages that are being output +taking care not to traverse into the pages tree, and then to fabricate +a new pages tree. + +Either way, care must be taken to handle other things such as +outlines, page labels, thumbnails, threads, etc. in a sensible way. +This may include simply omitting information other than page content. diff --git a/aclocal.m4 b/aclocal.m4 new file mode 100644 index 00000000..cfa57323 --- /dev/null +++ b/aclocal.m4 @@ -0,0 +1,6672 @@ +# libtool.m4 - Configure libtool for the host system. -*-Autoconf-*- +## Copyright 1996, 1997, 1998, 1999, 2000, 2001, 2003, 2004, 2005, 2006, 2007, +## 2008 Free Software Foundation, Inc. +## Originally by Gordon Matzigkeit , 1996 +## +## This file is free software; the Free Software Foundation gives +## unlimited permission to copy and/or distribute it, with or without +## modifications, as long as this notice is preserved. + +# serial 52 Debian 1.5.26-1 AC_PROG_LIBTOOL + + +# AC_PROVIDE_IFELSE(MACRO-NAME, IF-PROVIDED, IF-NOT-PROVIDED) +# ----------------------------------------------------------- +# If this macro is not defined by Autoconf, define it here. +m4_ifdef([AC_PROVIDE_IFELSE], + [], + [m4_define([AC_PROVIDE_IFELSE], + [m4_ifdef([AC_PROVIDE_$1], + [$2], [$3])])]) + + +# AC_PROG_LIBTOOL +# --------------- +AC_DEFUN([AC_PROG_LIBTOOL], +[AC_REQUIRE([_AC_PROG_LIBTOOL])dnl +dnl If AC_PROG_CXX has already been expanded, run AC_LIBTOOL_CXX +dnl immediately, otherwise, hook it in at the end of AC_PROG_CXX. + AC_PROVIDE_IFELSE([AC_PROG_CXX], + [AC_LIBTOOL_CXX], + [define([AC_PROG_CXX], defn([AC_PROG_CXX])[AC_LIBTOOL_CXX + ])]) +dnl And a similar setup for Fortran 77 support + AC_PROVIDE_IFELSE([AC_PROG_F77], + [AC_LIBTOOL_F77], + [define([AC_PROG_F77], defn([AC_PROG_F77])[AC_LIBTOOL_F77 +])]) + +dnl Quote A][M_PROG_GCJ so that aclocal doesn't bring it in needlessly. +dnl If either AC_PROG_GCJ or A][M_PROG_GCJ have already been expanded, run +dnl AC_LIBTOOL_GCJ immediately, otherwise, hook it in at the end of both. + AC_PROVIDE_IFELSE([AC_PROG_GCJ], + [AC_LIBTOOL_GCJ], + [AC_PROVIDE_IFELSE([A][M_PROG_GCJ], + [AC_LIBTOOL_GCJ], + [AC_PROVIDE_IFELSE([LT_AC_PROG_GCJ], + [AC_LIBTOOL_GCJ], + [ifdef([AC_PROG_GCJ], + [define([AC_PROG_GCJ], defn([AC_PROG_GCJ])[AC_LIBTOOL_GCJ])]) + ifdef([A][M_PROG_GCJ], + [define([A][M_PROG_GCJ], defn([A][M_PROG_GCJ])[AC_LIBTOOL_GCJ])]) + ifdef([LT_AC_PROG_GCJ], + [define([LT_AC_PROG_GCJ], + defn([LT_AC_PROG_GCJ])[AC_LIBTOOL_GCJ])])])]) +])])# AC_PROG_LIBTOOL + + +# _AC_PROG_LIBTOOL +# ---------------- +AC_DEFUN([_AC_PROG_LIBTOOL], +[AC_REQUIRE([AC_LIBTOOL_SETUP])dnl +AC_BEFORE([$0],[AC_LIBTOOL_CXX])dnl +AC_BEFORE([$0],[AC_LIBTOOL_F77])dnl +AC_BEFORE([$0],[AC_LIBTOOL_GCJ])dnl + +# This can be used to rebuild libtool when needed +LIBTOOL_DEPS="$ac_aux_dir/ltmain.sh" + +# Always use our own libtool. +LIBTOOL='$(SHELL) $(top_builddir)/libtool' +AC_SUBST(LIBTOOL)dnl + +# Prevent multiple expansion +define([AC_PROG_LIBTOOL], []) +])# _AC_PROG_LIBTOOL + + +# AC_LIBTOOL_SETUP +# ---------------- +AC_DEFUN([AC_LIBTOOL_SETUP], +[AC_PREREQ(2.50)dnl +AC_REQUIRE([AC_ENABLE_SHARED])dnl +AC_REQUIRE([AC_ENABLE_STATIC])dnl +AC_REQUIRE([AC_ENABLE_FAST_INSTALL])dnl +AC_REQUIRE([AC_CANONICAL_HOST])dnl +AC_REQUIRE([AC_CANONICAL_BUILD])dnl +AC_REQUIRE([AC_PROG_CC])dnl +AC_REQUIRE([AC_PROG_LD])dnl +AC_REQUIRE([AC_PROG_LD_RELOAD_FLAG])dnl +AC_REQUIRE([AC_PROG_NM])dnl + +AC_REQUIRE([AC_PROG_LN_S])dnl +AC_REQUIRE([AC_DEPLIBS_CHECK_METHOD])dnl +# Autoconf 2.13's AC_OBJEXT and AC_EXEEXT macros only works for C compilers! +AC_REQUIRE([AC_OBJEXT])dnl +AC_REQUIRE([AC_EXEEXT])dnl +dnl +AC_LIBTOOL_SYS_MAX_CMD_LEN +AC_LIBTOOL_SYS_GLOBAL_SYMBOL_PIPE +AC_LIBTOOL_OBJDIR + +AC_REQUIRE([_LT_AC_SYS_COMPILER])dnl +_LT_AC_PROG_ECHO_BACKSLASH + +case $host_os in +aix3*) + # AIX sometimes has problems with the GCC collect2 program.

QPDF's website is located at http://qpdf.qbilt.org/. + + + QPDF has been released under the terms of Version + 2.0 of the Artistic License, a copy of which appears in the + file Artistic-2.0 in the source distribution. + + + QPDF was originally created in 2001 and modified periodically + between 2001 and 2005 during my employment at Apex CoVantage. Upon my + departure from Apex, the company graciously allowed me to take + ownership of the software and continue maintaining as an open + source project, a decision for which I am very grateful. I have + made considerable enhancements to it since that time. I feel + fortunate to have worked for people who would make such a decision. + This work would not have been possible without their support. + + + + What is QPDF? + + QPDF is a program that does structural, content-preserving + transformations on PDF files. It could have been called something + like pdf-to-pdf. It also provides many useful + capabilities to developers of PDF-producing software or for people + who just want to look at the innards of a PDF file to learn more + about how they work. + + + QPDF is not a PDF content creation library, a + PDF viewer, or a program capable of converting PDF into other + formats. In particular, QPDF knows nothing about the semantics of + PDF content streams. If you are looking for something that can do + that, you should look elsewhere. However, once you have a valid + PDF file, QPDF can be used to transform that file in ways perhaps + your original PDF creation can't handle. For example, programs + generate simple PDF files but can't password-protect them, + web-optimize them, or perform other transformations of that type. + + + + Building and Installing QPDF + + This chapter describes how to build and install qpdf. Please see + also the README and + INSTALL files in the source distribution. + + + System Requirements + + The qpdf package has relatively few external dependencies. In + order to build qpdf, the following packages are required: + + + + zlib: http://www.zlib.net/ + + + + + pcre: http://www.pcre.org/ + + + + + gnu make 3.81 or newer: http://www.gnu.org/software/make + + + + + perl version 5.8 or newer: + http://www.perl.org/; + required for fix-qdf and the test suite. + + + + + GNU diffutils (any version): http://www.gnu.org/software/diffutils/ + is required to run the test suite. Note that this is the + version of diff present on virtually all GNU/Linux systems. + This is required because the test suite uses diff + -u. + + + + + + Part of qpdf's test suite does comparisons of the contents PDF + files by converting them images and comparing the images. You can + optionally disable this part of the test suite by running + configure with the + flag. If you leave + this enabled, the following additional requirements are required + by the test suite. Note that in no case are these items required + to use qpdf. + + + + libtiff: http://www.remotesensing.org/libtiff/ + + + + + GhostScript version 8.60 or newer: http://pages.cs.wisc.edu/~ghost/ + + + + This option is primarily intended for use by packagers of qpdf so + that they can avoid having the qpdf packages depend on tiff and + ghostscript software. + + + If Adobe Reader is installed as acroread, some + additional test cases will be enabled. These test cases simply + verify that Adobe Reader can open the files that qpdf creates. + They require version 8.0 or newer to pass. However, in order to + avoid having qpdf depend on non-free (as in liberty) software, the + test suite will still pass without Adobe reader, and the test + suite still exercises the full functionality of the software. + + + Pre-built documentation is distributed with qpdf, so you should + generally not need to rebuild the documentation. In order to + build the documentation from its docbook sources, you need the + docbook XML style sheets (http://downloads.sourceforge.net/docbook/). + To build the PDF version of the documentation, you need Apache fop + (http://xml.apache.org/fop/) + version 0.94 of higher. + + + + Build Instructions + + Building qpdf on UNIX is generally just a matter of running + + ./configure +make + + You can also run make check to run the test + suite and make install to install. Please run + ./configure --help for options on what can be + configured. You can also set the value of + DESTDIR during installation to install to a + temporary location, as is common with many open source packages. + Please see also the README and + INSTALL files in the source distribution. + + + There is currently no support for building qpdf on Windows. The + code is reasonably portable, however, and making it work on + Windows would probably be reasonably straightforward. A + significant amount of the code in QPDF has been known to work on + Windows in the past. + + + There are some other things you can do with the build. Although + qpdf uses autoconf, it does not use + automake but instead uses a + hand-crafted non-recursive Makefile that requires gnu make. If + you're really interested, please read the comments in the + top-level Makefile. + + + + + Running QPDF + + This chapter describes how to run the qpdf program from the command + line. + + + Basic Invocation + + When running qpdf, the basic invocation is as follows: + + qpdf + + This converts PDF file to PDF file + . The output file is functionally + identical to the input file but may have been structurally + reorganized. Also, orphaned objects will be removed from the + file. Many transformations are available as controlled by the + options below. + + + does not have to be seekable, even + when generating linearized files. Specifying + “” as + means to write to standard output. + + + Most options require an output file, but some testing or + inspection commands do not. These are specifically noted. + + + + Basic Options + + The following options are the most common ones and perform + commonly needed transformations. + + + + + + Specifies a password for accessing encrypted files. + + + + + + + + Causes generation of a linearized (web optimized) output file. + + + + + + + + Causes generation an encrypted output file. Please see for details on how to + specify encryption parameters. + + + + + + + + Removes any encryption on the file. A password must be + supplied if the file is password protected. + + + + + + + Password-protected files may be opened by specifying a password. + By default, qpdf will preserve any encryption data associated with + a file. If is specified, qpdf will + attempt to remove any encryption information. If + is specified, qpdf will replace the + document's encryption parameters with whatever is specified. + + + Note that qpdf does not obey encryption restrictions already + imposed on the file. Doing so would be meaningless since qpdf can + be used to remove encryption from the file entirely. This + functionality is not intended to be used for bypassing copyright + restrictions or other restrictions placed on files by their + producers. + + + + Encryption Options + + To change the encryption parameters of a file, use the --encrypt + flag. The syntax is + + + + Note that “” terminates parsing of + encryption flags and must be present even if no restrictions are + present. + + + Either or both of the user password and the owner password may be + empty strings. + + + The value for + may be 40 + or 128. The restriction flags are dependent upon key length. + When no additional restrictions are given, the default is to be + fully permissive. + + + If is 40, + the following restriction options are available: + + + + + + Determines whether or not to allow printing. + + + + + + + + Determines whether or not to allow document modification. + + + + + + + + Determines whether or not to allow text/image extraction. + + + + + + + + Determines whether or not to allow comments and form fill-in + and signing. + + + + + If is 128, + the following restriction options are available: + + + + + + Determines whether or not to allow accessibility to visually + impaired. + + + + + + + + Determines whether or not to allow text/graphic extraction. + + + + + + + + Controls printing access. + may be + one of the following: + + + + : allow full printing + + + + + : allow low-resolution printing only + + + + + : disallow printing + + + + + + + + + + + Controls modify access. + may be + one of the following: + + + + : allow full document modification + + + + + : allow comment authoring and form operations + + + + + : allow form field fill-in and signing + + + + + : allow document assembly only + + + + + : allow no modifications + + + + + + + + The default for each permission option is to be fully permissive. + + + + Advanced Transformation Options + + These transformation options control fine points of how qpdf + creates the output file. Mostly these are of use only to people + who are very familiar with the PDF file format or who are PDF + developers. The following options are available: + + + + + + Controls transformation of stream data. The value of + may be one + of the following: + + + + : recompress stream data when + possible (default) + + + + + : leave all stream data as is + + + + + : uncompress stream data when + possible + + + + + + + + + + + Enables or disables normalization of content streams. + + + + + + + + Prevents qpdf from attempting to recover damaged files. + + + + + + + + Controls handing of object streams. The value of + may be one of + the following: + + + + : preserve original object streams + (default) + + + + + : don't write any object streams + + + + + : use object streams wherever + possible + + + + + + + + + + + Tells qpdf to ignore any cross-reference streams. + + + + + + + + Turns on QDF mode. For additional information on QDF, please + see . + + + + + + + By default, when a stream is encoded using non-lossy filters that + qpdf understands and is not already compressed using a good + compression scheme, qpdf will uncompress and recompress streams. + Assuming proper filter implements, this is safe and generally + results in smaller files. This behavior may also be explicitly + requested with . + + + When is specified, qpdf + will never attempt to change the filtering of any stream data. + + + When is specified, qpdf + will attempt to remove any non-lossy filters that it supports. + This includes /FlateDecode, + /LZWDecode, /ASCII85Decode, + and /ASCIIHexDecode. This can be very useful + for inspecting the contents of various streams. + + + When is specified, qpdf + will attempt to normalize whitespace and newlines in page content + streams. This is generally safe but could, in some cases, cause + damage to the content streams. This option is intended for people + who wish to study PDF content streams or to debug PDF content. + You should not use this for “production” PDF files. + + + Ordinarily, qpdf will attempt to recover from certain types of + errors in PDF files. These include errors in the cross-reference + table, certain types of object numbering errors, and certain types + of stream length errors. Sometimes, qpdf may think it has + recovered but may not have actually recovered, so care should be + taken when using this option as some data loss is possible. The + option will prevent qpdf from + attempting recovery. In this case, it will fail on the first + error that it encounters. + + + Object streams, also known as compressed objects, were introduced + into the PDF specification at version 1.5, corresponding to + Acrobat 6. Some older PDF viewers may not support files with + object streams. qpdf can be used to transform files with object + streams to files without object streams or vice versa. As + mentioned above, there are three object stream modes: + , , and + . + + + In mode, the relationship to objects and + the streams that contain them is preserved from the original file. + In mode, all objects are written as + regular, uncompressed objects. The resulting file should be + readable by older PDF viewers. (Of course, the content of the + files may include features not supported by older viewers, but at + least the structure will be supported.) In + mode, qpdf will create its own object + streams. This will usually result in more compact PDF files, + though they may not be readable by older viewers. In this mode, + qpdf will also make sure the PDF version number in the header is + at least 1.5. + + + Ordinarily, qpdf reads cross-reference streams when they are + present in a PDF file. If + is specified, qpdf will ignore any cross-reference streams for + hybrid PDF files. The purpose of hybrid files is to make some + content available to viewers that are not aware of cross-reference + streams. It is almost never desirable to ignore them. The only + time when you might want to use this feature is if you are testing + creation of hybrid PDF files and wish to see how a PDF consumer + that doesn't understand object and cross-reference streams would + interpret such a file. + + + The flag turns on QDF mode, which changes + some of the defaults described above. Specifically, in QDF mode, + by default, stream data is uncompressed, content streams are + normalized, and encryption is removed. These defaults can still + be overridden by specifying the appropriate options as described + above. Additionally, in QDF mode, stream lengths are stored as + indirect objects, objects are laid out in a less efficient but + more readable fashion, and the documents are interspersed with + comments that make it easier for the user to find things and also + make it possible for fix-qdf to work properly. + QDF mode is intended for people, mostly developers, who wish to + inspect or modify PDF files in a text editor. For details, please + see . + + + + Testing, Inspection, and Debugging Options + + These options can be useful for digging into PDF files or for use + in automated test suites for software that uses the qpdf library. + When any of the options in this section are specified, no output + file should be given. The following options are available: + + + + + + Causes generation of a fixed value for /ID. This is intended + for testing only. Never use it for production files. + + + + + + + + Shows document encryption parameters. Also shows the + document's user password if the owner password is given. + + + + + + + + Checks file integrity and linearization status. + + + + + + + + Checks and displays all data in the linearization hint tables. + + + + + + + + Shows the contents of the cross-reference table in a + human-readable form. This is especially useful for files with + cross-reference streams which are stored in a binary format. + + + + + + + + Show the contents of the given object. This is especially + useful for inspecting objects that are inside of object + streams (also known as “compressed objects”). + + + + + + + + When used along with the + option, if the object is a stream, shows the raw stream data + instead of object's contents. + + + + + + + + When used along with the + option, if the object is a stream, shows the filtered stream + data instead of object's contents. If the stream is filtered + using filters that qpdf does not support, an error will be + issued. + + + + + + + + Shows the object and generation number for each page + dictionary object and for each content stream associated with + the page. Having this information makes it more convenient to + inspect objects from a particular page. + + + + + + + + When used along with , also shows + the object and generation numbers for the image objects on + each page. (At present, information about images in shared + resource dictionaries are not output by this command. This is + discussed in a comment in the source code.) + + + + + + + + Checks file structure and well as encryption and + linearization. A file for which + reports no errors may still have errors in stream data but + should otherwise be otherwise structurally sound. + + + + + + + The and + options are ignored unless + is given. Either of these options + will cause the stream data to be written to standard output. In + order to avoid commingling of stream data with other output, it is + recommend that these objects not be combined with other + test/inspection options. + + + If is given and + is also given, qpdf will + attempt to normalize the stream data as if it is a page content + stream. This attempt will be made even if it is not a page + content stream, in which case it will produce unusuable results. + + + + + QDF Mode + + In QDF mode, qpdf creates PDF files in what we call QDF + form. A PDF file in QDF form, sometimes called a QDF + file, is a completely valid PDF file that has + %QDF-1.0 as its third line (after the pdf header + and binary characters) and has certain other characteristics. The + purpose of QDF form is to make it possible to edit PDF files, with + some restrictions, in an ordinary text editor. This can be very + useful for experimenting with different PDF constructs or for + making one-off edits to PDF files (though there are other reasons + why this may not always work). + + + It is ordinarily very difficult to edit PDF files in a text editor + for two reasons: most meaningful data in PDF files is compressed, + and PDF files are full of offset and length information that makes + it hard to add or remove data. A QDF file is organized in a manner + such that, if edits are kept within certain constraints, the + fix-qdf program, distributed with qpdf, is able + to restore edited files to a correct state. The + fix-qdf program takes no command-line + arguments. It reads a possibly edited QDF file from standard input + and writes a repaired file to standard output. + + + The following attributes characterize a QDF file: + + + + All objects appear in numerical order in the PDF file, including + when objects appear in object streams. + + + + + Objects are printed in an easy-to-read format, and all line + endings are normalized to UNIX line endings. + + + + + Unless specifically overridden, streams appear uncompressed + (when qpdf supports the filters and they are compressed with a + non-lossy compression scheme), and most content streams are + normalized (line endings are converted to just a UNIX-style + linefeeds). + + + + + All streams lengths are represented as indirect objects, and the + stream length object is always the next object after the stream. + If the stream data does not end with a newline, an extra newline + is inserted, and a special comment appears after the stream + indicating that this has been done. + + + + + If the PDF file contains object streams, if object stream + n contains k objects, + those objects are numbered from n+1 through + n+k, and the object number/offset pairs + appear on a separate line for each object. Additionally, each + object in the object stream is preceded by a comment indicating + its object number and index. This makes it very easy to find + objects in object streams. + + + + + All beginnings of objects, stream tokens, + endstream tokens, and + endobj tokens appear on lines by themselves. + A blank line follows every endobj token. + + + + + If there is a cross-reference stream, it is unfiltered. + + + + + Page dictionaries and page content streams are marked with + special comments that make them easy to find. + + + + + + When editing a QDF file, any edits can be made as long as the above + constraints are maintained. This means that you can freely edit a + page's content without worrying about messing up the QDF file. It + is also possible to add new objects so long as those objects are + added after the last object in the file or subsequent objects are + renumbered. If a QDF file has object streams in it, you can always + add the new objects before the xref stream and then change the + number of the xref stream, since nothing generally ever references + it by number. + + + It is not generally practical to remove objects from QDF files + without messing up object numbering, but if you remove all + references to an object, you can run qpdf on the file (after + running fix-qdf), and qpdf will omit the + now-orphaned object. + + + When fix-qdf is run, it goes through the file + and recomputes the following parts of the file: + + + + the /N, /W, and + /First keys of all object stream dictionaries + + + + + the pairs of numbers representing object numbers and offsets of + objects in object streams + + + + + all stream lengths + + + + + the cross-reference table or cross-reference stream + + + + + the offset to the cross-reference table or cross-reference + stream following the startxref token + + + + + + + Using the QPDF Library + + The source tree for the qpdf package has an + examples directory that contains a few + example programs. The qpdf/qpdf.cc source + file also serves as a useful example since it exercises almost all + of the qpdf library's public interface. The best source of + documentation on the library itself is reading comments in + include/qpdf/QPDF.hh, + include/qpdf/QDFWriter.hh, and + include/qpdf/QPDFObjectHandle.hh. + + + All header files are installed in the include/qpdf directory. It + is recommend that you use #include + <qpdf/QPDF.hh> rather than adding + include/qpdf to your include path. + + + When linking against the qpdf library, you may also need to + specify -lpcre -lz on your link command. If + your system understands how to read libtool + .la files, this may not be necessary. + + + + Design and Library Notes + + Introduction + + This section was written prior to the implementation of the qpdf + package and was subsequently modified to reflect the + implementation. In some cases, for purposes of explanation, it + may differ slightly from the actual implementation. As always, + the source code and test suite are authoritative. Even if there + are some errors, this document should serve as a road map to + understanding how this code works. + + + In general, one should adhere strictly to a specification when + writing but be liberal in reading. This way, the product of our + software will be accepted by the widest range of other programs, + and we will accept the widest range of input files. This library + attempts to conform to that philosophy whenever possible but also + aims to provide strict checking for people who want to validate + PDF files. If you don't want to see warnings and are trying to + write something that is tolerant, you can call + setSuppressWarnings(true). If you want to fail + on the first error, you can call + setAttemptRecovery(false). The default + behavior is to generating warnings for recoverable problems. Note + that recovery will not always produce the desired results even if + it is able to get through the file. Unlike most other PDF files + that produce generic warnings such as “This file is + damaged,”, qpdf generally issues a detailed error message + that would be most useful to a PDF developer. This is by design + as there seems to be a shortage of PDF validation tools out + there. (This was, in fact, one of the major motivations behind + the initial creation of qpdf.) + + + + Design Goals + + The QPDF package includes support for reading and rewriting PDF + files. It aims to hide from the user details involving object + locations, modified (appended) PDF files, the + directness/indirectness of objects, and stream filters including + encryption. It does not aim to hide knowledge of the object + hierarchy or content stream contents. Put another way, a user of + the qpdf library is expected to have knowledge about how PDF files + work, but is not expected to have to keep track of bookkeeping + details such as file positions. + + + A user of the library never has to care whether an object is + direct or indirect. All access to objects deals with this + transparently. All memory management details are also handled by + the library. + + + The PointerHolder object is used internally + by the library to deal with memory management. This is basically + a smart pointer object very similar in spirit to the Boost + library's shared_ptr object, but predating + it by several years. This library also makes use of a technique + for giving fine-grained access to methods in one class to other + classes by using public subclasses with friends and only private + members that in turn call private methods of the containing class. + See QPDFObjectHandle::Factory as an + example. + + + The top-level qpdf class is QPDF. A + QPDF object represents a PDF file. The + library provides methods for both accessing and mutating PDF + files. + + + QPDFObject is the basic PDF Object class. + It is an abstract base class from which are derived classes for + each type of PDF object. Clients do not interact with Objects + directly but instead interact with + QPDFObjectHandle. + + + QPDFObjectHandle contains + PointerHolder<QPDFObject> and + includes accessor methods that are type-safe proxies to the + methods of the derived object classes as well as methods for + querying object types. They can be passed around by value, + copied, stored in containers, etc. with very low overhead. + Instances of QPDFObjectHandle always + contain a reference back to the QPDF object + from which they were created. A + QPDFObjectHandle may be direct or indirect. + If indirect, the QPDFObject the + PointerHolder initially points to is a null + pointer. In this case, the first attempt to access the underlying + QPDFObject will result in the + QPDFObject being resolved via a call to the + referenced QPDF instance. This makes it + essentially impossible to make coding errors in which certain + things will work for some PDF files and not for others based on + which objects are direct and which objects are indirect. + + + There is no public interface for creating instances of + QPDFObjectHandle. They can be created only inside the QPDF + library. This is generally done through a call to the private + method QPDF::readObject which uses + QPDFTokenizer to read an indirect object at + a given file position and return a + QPDFObjectHandle that encapsulates it. + There are also internal methods to create fabricated indirect + objects from existing direct objects or to change an indirect + object into a direct object, though these steps are not performed + except to support rewriting. + + + When the QPDF class creates a new object, + it dynamically allocates the appropriate type of + QPDFObject and immediately hands the + pointer to an instance of QPDFObjectHandle. + The parser reads a token from the current file position. If the + token is a not either a dictionary or array opener, an object is + immediately constructed from the single token and the parser + returns. Otherwise, the parser is invoked recursively in a + special mode in which it accumulates objects until it finds a + balancing closer. During this process, the + “R” keyword is recognized and an + indirect QPDFObjectHandle may be + constructed. + + + The QPDF::resolve() method, which is used to + resolve an indirect object, may be invoked from the + QPDFObjectHandle class. It first checks a + cache to see whether this object has already been read. If not, + it reads the object from the PDF file and caches it. It the + returns the resulting QPDFObjectHandle. + The calling object handle then replaces its + PointerHolder<QDFObject> with the one + from the newly returned QPDFObjectHandle. + In this way, only a single copy of any direct object need exist + and clients can access objects transparently without knowing + caring whether they are direct or indirect objects. Additionally, + no object is ever read from the file more than once. That means + that only the portions of the PDF file that are actually needed + are ever read from the input file, thus allowing the qpdf package + to take advantage of this important design goal of PDF files. + + + If the requested object is inside of an object stream, the object + stream itself is first read into memory. Then the tokenizer reads + objects from the memory stream based on the offset information + stored in the stream. Those individual objects are cached, after + which the temporary buffer holding the object stream contents are + discarded. In this way, the first time an object in an object + stream is requested, all objects in the stream are cached. + + + An instance of QPDF is constructed by using + the class's default constructor. If desired, the + QPDF object may be configured with various + methods that change its default behavior. Then the + QPDF::processFile() method is passed the name + of a PDF file, which permanently associates the file with that + QPDF object. A password may also be given for access to + password-protected files. QPDF does not enforce encryption + parameters and will treat user and owner passwords equivalently. + Either password may be used to access an encrypted file. + + + As pointed out earlier, the intention is not for qpdf to be used + to bypass security on files. but as any open source PDF consumer + may be easily modified to bypass basic PDF document security, + and qpdf offers may transformations that can do this as well, + there seems to be little point in the added complexity of + conditionally enforcing document security. + + + QPDF will allow recovery of a user password + given an owner password. The input PDF file must be seekable. + (Output files written by QPDFWriter need + not be seekable, even when creating linearized files.) During + construction, QPDF validates the PDF file's + header, and then reads the cross reference tables and trailer + dictionaries. The QPDF class keeps only + the first trailer dictionary though it does read all of them so it + can check the /Prev key. + QPDF class users may request the root + object and the trailer dictionary specifically. The cross + reference table is kept private. Objects may then be requested by + number of by walking the object tree. + + + When a PDF file has a cross-reference stream instead of a + cross-reference table and trailer, requesting the document's + trailer dictionary returns the stream dictionary from the + cross-reference stream instead. + + + There are some convenience routines for very common operations + such as walking the page tree and returning a vector of all page + objects. For full details, please see the header file + QPDF.hh. + + + The following example should clarify how + QPDF processes a simple file. + + + + Client constructs QPDF + pdf and calls + pdf.processFile("a.pdf");. + + + + + The QPDF class checks the beginning of + a.pdf for + %!PDF-1.[0-9]+. It then reads the cross + reference table mentioned at the end of the file, ensuring that + it is looking before the last %%EOF. After + getting to trailer keyword, it invokes the + parser. + + + + + The parser sees “<<”, so + it calls itself recursively in dictionary creation mode. + + + + + In dictionary creation mode, the parser keeps accumulating + objects until it encounters + “>>”. Each object that is + read is pushed onto a stack. If + “R” is read, the last two + objects on the stack are inspected. If they are integers, they + are popped off the stack and their values are used to construct + an indirect object handle which is then pushed onto the stack. + When “>>” is finally read, + the stack is converted into a + QPDF_Dictionary which is placed in a + QPDFObjectHandle and returned. + + + + + The resulting dictionary is saved as the trailer dictionary. + + + + + The /Prev key is searched. If present, + QPDF seeks to that point and repeats + except that the new trailer dictionary is not saved. If + /Prev is not present, the initial parsing + process is complete. + + + If there is an encryption dictionary, the document's encryption + parameters are initialized. + + + + + The client requests root object. The + QPDF class gets the value of root key + from trailer dictionary and returns it. It is an unresolved + indirect QPDFObjectHandle. + + + + + The client requests the /Pages key from root + QPDFObjectHandle. The + QPDFObjectHandle notices that it is + indirect so it asks QPDF to resolve it. + QPDF looks in the object cache for an + object with the root dictionary's object ID and generation + number. Upon not seeing it, it checks the cross reference + table, gets the offset, and reads the object present at that + offset. It stores the result in the object cache and returns + the cached result. The calling + QPDFObjectHandle replaces its object + pointer with the one from the resolved + QPDFObjectHandle, verifies that it a + valid dictionary object, and returns the (unresolved indirect) + QPDFObject handle to the top of the + Pages hierarchy. + + + As the client continues to request objects, the same process is + followed for each new requested object. + + + + + + + Encryption + + Encryption is supported transparently by qpdf. When opening a PDF + file, if an encryption dictionary exists, the + QPDF object processes this dictionary using + the password (if any) provided. The primary decryption key is + computed and cached. No further access is made to the encryption + dictionary after that time. When an object is read from a file, + the object ID and generation of the object in which it is + contained is always known. Using this information along with the + stored encryption key, all stream and string objects are + transparently decrypted. Raw encrypted objects are never stored + in memory. This way, nothing in the library ever has to know or + care whether it is reading an encrypted file. + + + An interface is also provided for writing encrypted streams and + strings given an encryption key. This is used by + QPDFWriter when it rewrites encrypted + files. + + + + Writing PDF Files + + The qpdf library supports file writing of + QPDF objects to PDF files through the + QPDFWriter class. The + QPDFWriter class has two writing modes: one + for non-linearized files, and one for linearized files. See for a description of linearization + is implemented. This section describes how we write + non-linearized files including the creation of QDF files (see + . + + + This outline was written prior to implementation and is not + exactly accurate, but it provides a correct “notional” + idea of how writing works. Look at the code in + QPDFWriter for exact details. + + + + Initialize state: + + + + next object number = 1 + + + + + object queue = empty + + + + + renumber table: old object id/generation to new id/0 = empty + + + + + xref table: new id -> offset = empty + + + + + + + + Create a QPDF object from a file. + + + + + Write header for new PDF file. + + + + + Request the trailer dictionary. + + + + + For each value that is an indirect object, grab the next object + number (via an operation that returns and increments the + number). Map object to new number in renumber table. Push + object onto queue. + + + + + While there are more objects on the queue: + + + + Pop queue. + + + + + Look up object's new number n in the + renumbering table. + + + + + Store current offset into xref table. + + + + + Write n 0 obj. + + + + + If object is null, whether direct or indirect, write out + null, thus eliminating unresolvable indirect object + references. + + + + + If the object is a stream stream, write stream contents, + piped through any filters as required, to a memory buffer. + Use this buffer to determine the stream length. + + + + + If object is not a stream, array, or dictionary, write out + its contents. + + + + + If object is an array or dictionary (including stream), + traverse its elements (for array) or values (for + dictionaries), handling recursive dictionaries and arrays, + looking for indirect objects. When an indirect object is + found, if it is not resolvable, ignore. (This case is + handled when writing it out.) Otherwise, look it up in the + renumbering table. If not found, grab the next available + object number, assign to the referenced object in the + renumbering table, and push the referenced object onto the + queue. As a special case, when writing out a stream + dictionary, replace length, filters, and decode parameters + as required. + + + Write out dictionary or array, replacing any unresolvable + indirect object references with null (pdf spec says + reference to non-existent object is legal and resolves to + null) and any resolvable ones with references to the + renumbered objects. + + + + + If the object is a stream, write + stream\n, the stream contents (from the + memory buffer), and \nendstream\n. + + + + + When done, write endobj. + + + + + + + + + Once we have finished the queue, all referenced objects will have + been written out and all deleted objects or unreferenced objects + will have been skipped. The new cross-reference table will + contain an offset for every new object number from 1 up to the + number of objects written. This can be used to write out a new + xref table. Finally we can write out the trailer dictionary with + appropriately computed /ID (see spec, 8.3, File Identifiers), the + cross reference table offset, and %%EOF. + + + + Filtered Streams + + Support for streams is implemented through the + Pipeline interface which was designed for + this package. + + + When reading streams, create a series of + Pipeline objects. The + Pipeline abstract base requires + implementation write() and + finish() and provides an implementation of + getNext(). Each pipeline object, upon + receiving data, does whatever it is going to do and then writes + the data (possibly modified) to its successor. Alternatively, a + pipeline may be an end-of-the-line pipeline that does something + like store its output to a file or a memory buffer ignoring a + successor. For additional details, look at + Pipeline.hh. + + + QPDF can read raw or filtered streams. + When reading a filtered stream, the QPDF + class creates a Pipeline object for one of + each appropriate filter object and chains them together. The last + filter should write to whatever type of output is required. The + QPDF class has an interface to write raw or + filtered stream contents to a given pipeline. + + + + + Linearization + + This chapter describes how QPDF and + QPDFWriter implement creation and processing + of linearized PDFS. + + + Basic Strategy for Linearization + + To avoid the incestuous problem of having the qpdf library + validate its own linearized files, we have a special linearized + file checking mode which can be invoked via qpdf + --check-linearization (or qpdf + --check). This mode reads the linearization parameter + dictionary and the hint streams and validates that object + ordering, parameters, and hint stream contents are correct. The + validation code was first tested against linearized files created + by external tools (Acrobat and pdlin) and then used to validate + files created by QPDFWriter itself. + + + + Preparing For Linearization + + Before creating a linearized PDF file from any other PDF file, the + PDF file must be altered such that all page attributes are + propagated down to the page level (and not inherited from parents + in the /Pages tree). We also have to know + which objects refer to which other objects, being concerned with + page boundaries and a few other cases. We refer to this part of + preparing the PDF file as optimization, + discussed in . Note the, in + this context, the term optimization is a + qpdf term, and the term linearization is a + term from the PDF specification. Do not be confused by the fact + that many applications refer to linearization as optimization or + web optimization. + + + When creating linearized PDF files from optimized PDF files, there + are really only a few issues that need to be dealt with: + + + + Creation of hints tables + + + + + Placing objects in the correct order + + + + + Filling in offsets and byte sizes + + + + + + + Optimization + + In order to perform various operations such as linearization and + splitting files into pages, it is necessary to know which objects + are referenced by which pages, page thumbnails, and root and + trailer dictionary keys. It is also necessary to ensure that all + page-level attributes appear directly at the page level and are + not inherited from parents in the pages tree. + + + We refer to the process of enforcing these constraints as + optimization. As mentioned above, note + that some applications refer to linearization as optimization. + Although this optimization was initially motivated by the need to + create linearized files, we are using these terms separately. + + + PDF file optimization is implemented in the + QPDF_optimization.cc source file. That file + is richly commented and serves as the primary reference for the + optimization process. + + + After optimization has been completed, the private member + variables obj_user_to_objects and + object_to_obj_users in + QPDF have been populated. Any object that + has more than one value in the + object_to_obj_users table is shared. Any + object that has exactly one value in the + object_to_obj_users table is private. To find + all the private objects in a page or a trailer or root dictionary + key, one merely has make this determination for each element in + the obj_user_to_objects table for the given + page or key. + + + Note that pages and thumbnails have different object user types, + so the above test on a page will not include objects referenced by + the page's thumbnail dictionary and nothing else. + + + + Writing Linearized Files + + We will create files with only primary hint streams. We will + never write overflow hint streams. (As of PDF version 1.4, + Acrobat doesn't either, and they are never necessary.) The hint + streams contain offset information to objects that point to where + they would be if the hint stream were not present. This means + that we have to calculate all object positions before we can + generate and write the hint table. This means that we have to + generate the file in two passes. To make this reliable, + QPDFWriter in linearization mode invokes + exactly the same code twice to write the file to a pipeline. + + + In the first pass, the target pipeline is a count pipeline chained + to a discard pipeline. The count pipeline simply passes its data + through to the next pipeline in the chain but can return the + number of bytes passed through it at any intermediate point. The + discard pipeline is an end of line pipeline that just throws its + data away. The hint stream is not written and dummy values with + adequate padding are stored in the first cross reference table, + linearization parameter dictionary, and /Prev key of the first + trailer dictionary. All the offset, length, object renumbering + information, and anything else we need for the second pass is + stored. + + + At the end of the first pass, this information is passed to the + QPDF class which constructs a compressed + hint stream in a memory buffer and returns it. + QPDFWriter uses this information to write a + complete hint stream object into a memory buffer. At this point, + the length of the hint stream is known. + + + In the second pass, the end of the pipeline chain is a regular + file instead of a discard pipeline, and we have known values for + all the offsets and lengths that we didn't have in the first pass. + We have to adjust offsets that appear after the start of the hint + stream by the length of the hint stream, which is known. Anything + that is of variable length is padded, with the padding code + surrounding any writing code that differs in the two passes. This + ensures that changes to the way things are represented never + results in offsets that were gathered during the first pass + becoming incorrect for the second pass. + + + Using this strategy, we can write linearized files to a + non-seekable output stream with only a single pass to disk or + wherever the output is going. + + + + Calculating Linearization Data + + Once a file is optimized, we have information about which objects + access which other objects. We can then process these tables to + decide which part (as described in “Linearized PDF Document + Structure” in the PDF specification) each object is + contained within. This tells us the exact order in which objects + are written. The QPDFWriter class asks for + this information and enqueues objects for writing in the proper + order. It also turns on a check that causes an exception to be + thrown if an object is encountered that has not already been + queued. (This could happen only if there were a bug in the + traversal code used to calculate the linearization data.) + + + + Known Issues with Linearization + + There are a handful of known issues with this linearization code. + These issues do not appear to impact the behavior of linearized + files which still work as intended: it is possible for a web + browser to begin to display them before they are fully + downloaded. In fact, it seems that various other programs that + create linearized files have many of these same issues. These + items make reference to terminology used in the linearization + appendix of the PDF specification. + + + + Thread Dictionary information keys appear in part 4 with the + rest of Threads instead of in part 9. Objects in part 9 are + not grouped together functionally. + + + + + We are not calculating numerators for shared object positions + within content streams or interleaving them within content + streams. + + + + + We generate only page offset, shared object, and outline hint + tables. It would be relatively easy to add some additional + tables. We gather most of the information needed to create + thumbnail hint tables. There are comments in the code about + this. + + + + + + + Debugging Note + + The qpdf --show-linearization command can show + the complete contents of linearization hint streams. To look at + the raw data, you can extract the filtered contents of the + linearization hint tables using qpdf --show-object=n + --filtered-stream-data. Then, to convert this into a + bit stream (since linearization tables are bit streams written + without regard to byte boundaries), you can pipe the resulting + data through the following perl code: + + use bytes; +binmode STDIN; +undef $/; +my $a = <STDIN>; +my @ch = split(//, $a); +map { printf("%08b", ord($_)) } @ch; +print "\n"; + + + + + + Object and Cross-Reference Streams + + This chapter provides information about the implementation of + object stream and cross-reference stream support in qpdf. + + + Object Streams + + Object streams can contain any regular object except the + following: + + + + stream objects + + + + + objects with generation > 0 + + + + + the encryption dictionary + + + + + objects containing the /Length of another stream + + + + In addition, Adobe reader (at least as of version 8.0.0) appears + to not be able to handle having the document catalog appear in an + object stream if the file is encrypted, though this is not + specifically disallowed by the specification. + + + There are additional restrictions for linearized files. See for details. + + + The PDF specification refers to objects in object streams as + “compressed objects” regardless of whether the object + stream is compressed. + + + The generation number of every object in an object stream must be + zero. It is possible to delete and replace an object in an object + stream with a regular object. + + + The object stream dictionary has the following keys: + + + + /N: number of objects + + + + + /First: byte offset of first object + + + + + /Extends: indirect reference to stream that + this extends + + + + + + Stream collections are formed with /Extends. + They must form a directed acyclic graph. These can be used for + semantic information and are not meaningful to the PDF document's + syntactic structure. Although qpdf preserves stream collections, + it never generates them and doesn't make use of this information + in any way. + + + The specification recommends limiting the number of objects in + object stream for efficiency in reading and decoding. Acrobat 6 + uses no more than objects per object stream for linearized files + and no more 200 objects per stream for non-linearized files. + QPDFWriter, in object stream generation + mode, never puts more than 100 objects in an object stream. + + + Object stream contents consists of N pairs of + integers, each of which is the object number and the byte offset + of the object relative to the first object in the stream, followed + by the objects themselves, concatenated. + + + + Cross-Reference Streams + + For non-hybrid files, the value following + startxref is the byte offset to the xref stream + rather than the word xref. + + + For hybrid files (files containing both xref tables and + cross-reference streams), the xref table's trailer dictionary + contains the key /XRefStm whose value is the + byte offset to a cross-reference stream that supplements the xref + table. A PDF 1.5-compliant application should read the xref table + first. Then it should replace any object that it has already seen + with any defined in the xref stream. Then it should follow any + /Prev pointer in the original xref table's + trailer dictionary. The specification is not clear about what + should be done, if anything, with a /Prev + pointer in the xref stream referenced by an xref table. The + QPDF class ignores it, which is probably + reasonable since, if this case were to appear for any sensible PDF + file, the previous xref table would probably have a corresponding + /XRefStm pointer of its own. For example, if a + hybrid file were appended, the appended section would have its own + xref table and /XRefStm. The appended xref + table would point to the previous xref table which would point the + /XRefStm, meaning that the new + /XRefStm doesn't have to point to it. + + + Since xref streams must be read very early, they may not be + encrypted, and the may not contain indirect objects for keys + required to read them, which are these: + + + + /Type: value /XRef + + + + + /Size: value n+1: where + n is highest object number (same as + /Size in the trailer dictionary) + + + + + /Index (optional): value + [n count ...] + used to determine which objects' information is stored in this + stream. The default is [0 /Size]. + + + + + /Prev: value + offset: byte offset of previous xref + stream (same as /Prev in the trailer + dictionary) + + + + + /W [...]: sizes of each field in the xref + table + + + + + + The other fields in the xref stream, which may be indirect if + desired, are the union of those from the xref table's trailer + dictionary. + + + Cross-Reference Stream Data + + The stream data is binary and encoded in big-endian byte order. + Entries are concatenated, and each entry has a length equal to + the total of the entries in /W above. Each + entry consists of one or more fields, the first of which is the + type of the field. The number of bytes for each field is given + by /W above. A 0 in /W + indicates that the field is omitted and has the default value. + The default value for the field type is + “1”. All other default values are + “0”. + + + PDF 1.5 has three field types: + + + + 0: for free objects. Format: 0 obj + next-generation, same as the free table in a + traditional cross-reference table + + + + + 1: regular non-compressed object. Format: 1 offset + generation + + + + + 2: for objects in object streams. Format: 2 + object-stream-number index, the number of object + stream containing the object and the index within the object + stream of the object. + + + + + + It seems standard to have the first entry in the table be + 0 0 0 instead of 0 0 ffff + if there are no deleted objects. + + + + + Implications for Linearized Files + + For linearized files, the linearization dictionary, document + catalog, and page objects may not be contained in object streams. + + + Objects stored within object streams are given the highest range + of object numbers within the main and first-page cross-reference + sections. + + + It is okay to use cross-reference streams in place of regular xref + tables. There are on special considerations. + + + Hint data refers to object streams themselves, not the objects in + the streams. Shared object references should also be made to the + object streams. There are no reference in any hint tables to the + object numbers of compressed objects (objects within object + streams). + + + When numbering objects, all shared objects within both the first + and second halves of the linearized files must be numbered + consecutively after all normal uncompressed objects in that half. + + + + Implementation Notes + + There are three modes for writing object streams: + , , and + . In disable mode, we do not generate + any object streams, and we also generate an xref table rather than + xref streams. This can be used to generate PDF files that are + viewable with older readers. In preserve mode, we write object + streams such that written object streams contain the same objects + and /Extends relationships as in the original + file.
