<h2 class="title" id="introduction">Introduction</h2>
|
|
<p>PDFio is a simple C library for reading and writing PDF files. The primary goals of pdfio are:</p>
|
|
<ul>
|
|
<li><p>Read any PDF file with or without encryption or linearization</p>
|
|
</li>
|
|
<li><p>Write PDF files without encryption or linearization</p>
|
|
</li>
|
|
<li><p>Extract or embed useful metadata (author, creator, page information, etc.)</p>
|
|
</li>
|
|
<li><p>"Filter" PDF files, for example to extract a range of pages or to embed fonts that are missing from a PDF</p>
|
|
</li>
|
|
<li><p>Provide access to objects used for each page</p>
|
|
</li>
|
|
</ul>
|
|
<p>PDFio is <em>not</em> concerned with rendering or viewing a PDF file, although a PDF RIP or viewer could be written using it.</p>
|
|
<p>PDFio is Copyright © 2021 by Michael R Sweet and is licensed under the Apache License Version 2.0 with an (optional) exception to allow linking against GPL2/LGPL2 software. See the files "LICENSE" and "NOTICE" for more information.</p>
|
|
<h3 class="title" id="requirements">Requirements</h3>
|
|
<p>PDFio requires the following to build the software:</p>
|
|
<ul>
|
|
<li><p>A C99 compiler such as Clang, GCC, or MS Visual C</p>
|
|
</li>
|
|
<li><p>A POSIX-compliant <code>make</code> program</p>
|
|
</li>
|
|
<li><p>ZLIB (<a href="https://www.zlib.net">https://www.zlib.net</a>) 1.0 or higher</p>
|
|
</li>
|
|
</ul>
|
|
<p>IDE files for Xcode (macOS/iOS) and Visual Studio (Windows) are also provided.</p>
|
|
<h3 class="title" id="installing-pdfio">Installing pdfio</h3>
|
|
<p>PDFio comes with a portable makefile that will work on any POSIX-compliant system with ZLIB installed. To make it, run:</p>
|
|
<pre><code>make all
|
|
</code></pre>
|
|
<p>To test it, run:</p>
|
|
<pre><code>make test
|
|
</code></pre>
|
|
<p>To install it, run:</p>
|
|
<pre><code>make install
|
|
</code></pre>
|
|
<p>If you want a shared library, run:</p>
|
|
<pre><code>make all-shared
|
|
make install-shared
|
|
</code></pre>
|
|
<p>The default installation location is "/usr/local". Pass the <code>prefix</code> variable to make to install it to another location:</p>
|
|
<pre><code>make install prefix=/some/other/directory
|
|
</code></pre>
|
|
<p>The makefile installs the pdfio header to "${prefix}/include", the library to "${prefix}/lib", the <code>pkg-config</code> file to "${prefix}/lib/pkgconfig", the man page to "${prefix}/share/man/man3", and the documentation to "${prefix}/share/doc/pdfio".</p>
|
|
<p>The makefile supports the following variables that can be specified in the make command or as environment variables:</p>
|
|
<ul>
|
|
<li><p><code>AR</code>: the library archiver (default "ar")</p>
|
|
</li>
|
|
<li><p><code>ARFLAGS</code>: options for the library archiver (default "cr")</p>
|
|
</li>
|
|
<li><p><code>CC</code>: the C compiler (default "cc")</p>
|
|
</li>
|
|
<li><p><code>CFLAGS</code>: options for the C compiler (default "")</p>
|
|
</li>
|
|
<li><p><code>CODESIGN_IDENTITY</code>: the identity to use when code signing the shared library on macOS (default "Developer ID")</p>
|
|
</li>
|
|
<li><p><code>COMMONFLAGS</code>: options for the C compiler and linker (typically architecture and optimization options, default is "-Os -g")</p>
|
|
</li>
|
|
<li><p><code>CPPFLAGS</code>: options for the C preprocessor (default "")</p>
|
|
</li>
|
|
<li><p><code>DESTDIR" and "DSTROOT</code>: specifies a root directory when installing (default is "", specify only one)</p>
|
|
</li>
|
|
<li><p><code>DSOFLAGS</code>: options for the C compiler when linking the shared library (default "")</p>
|
|
</li>
|
|
<li><p><code>LDFLAGS</code>: options for the C compiler when linking the test programs (default "")</p>
|
|
</li>
|
|
<li><p><code>LIBS</code>: library options when linking the test programs (default "-lz")</p>
|
|
</li>
|
|
<li><p><code>RANLIB</code>: program that generates a table-of-contents in a library (default "ranlib")</p>
|
|
</li>
|
|
<li><p><code>prefix</code>: specifies the installation directory (default "/usr/local")</p>
|
|
</li>
|
|
</ul>

<h3 class="title" id="visual-studio-project">Visual Studio Project</h3>
|
|
<blockquote>
|
|
<p>Note: I haven't yet added this...</p>
|
|
</blockquote>
|
|
<p>The Visual Studio solution ("pdfio.sln") is provided for Windows developers generates both a static library and DLL.</p>
|
|
<h3 class="title" id="xcode-project">Xcode Project</h3>
|
|
<p>There is also an Xcode project ("pdfio.xcodeproj") you can use on macOS which generates a static library that will be installed under "/usr/local" with:</p>
|
|
<pre><code>sudo xcodebuild install
|
|
</code></pre>
|
|
<p>You can reproduce this with the makefile using:</p>
|
|
<pre><code>sudo make 'COMMONFLAGS="-Os -mmacosx-version-min=10.14 -arch x86_64 -arch arm64"' install
|
|
</code></pre>
|
|
<h3 class="title" id="detecting-pdfio">Detecting PDFio</h3>
|
|
<p>PDFio can be detected using the <code>pkg-config</code> command, for example:</p>
|
|
<pre><code>if pkg-config --exists pdfio; then
|
|
...
|
|
fi
|
|
</code></pre>
|
|
<p>In a makefile you can add the necessary compiler and linker options with:</p>
|
|
<pre><code class="language-make">CFLAGS += `pkg-config --cflags pdfio`
|
|
LIBS += `pkg-config --libs pdfio`
|
|
</code></pre>
|
|
<h3 class="title" id="header-files">Header Files</h3>
|
|
<p>PDFio provides a primary header file that is always used:</p>
|
|
<pre><code class="language-c"><span class="directive">#include <pdfio.h></span>
|
|
</code></pre>
|
|
<p>PDFio also provides content helper functions that are defined in a separate header file:</p>
|
|
<pre><code class="language-c"><span class="directive">#include <pdfio-content.h></span>
|
|
</code></pre>
|
|
<h2 class="title" id="api-overview">API Overview</h2>
|
|
<p>PDFio exposes several types:</p>
|
|
<ul>
|
|
<li><p><code>pdfio_file_t</code>: A PDF file (for reading or writing)</p>
|
|
</li>
|
|
<li><p><code>pdfio_array_t</code>: An array of values</p>
|
|
</li>
|
|
<li><p><code>pdfio_dict_t</code>: A dictionary of key/value pairs in a PDF file, object, etc.</p>
|
|
</li>
|
|
<li><p><code>pdfio_obj_t</code>: An object in a PDF file</p>
|
|
</li>
|
|
<li><p><code>pdfio_stream_t</code>: An object stream</p>
|
|
</li>
