.SS Requirements
|
||||||
|
.PP
|
||||||
|
PDFio requires the following to build the software:
|
||||||
|
.IP \(bu 5
|
||||||
|
.PP
|
||||||
|
A C99 compiler such as Clang, GCC, or MS Visual C
|
||||||
|
|

||||||
|
.PP
|
||||||
|
A POSIX\-compliant make program
|
||||||
|
|
||||||
|
.IP \(bu 5
|
||||||
|
.PP
|
||||||
|
ZLIB (https://www.zlib.net) 1.0 or higher
|
||||||
|
|
||||||
|
|
||||||
|
.PP
|
||||||
|
IDE files for Xcode (macOS/iOS) and Visual Studio (Windows) are also provided.
|
||||||
|
.SS Installing pdfio
|
||||||
|
.PP
|
||||||
|
PDFio comes with a portable makefile that will work on any POSIX\-compliant system with ZLIB installed. To make it, run:
|
||||||
|
.nf
|
||||||
|
|
||||||
|
make all
|
||||||
|
.fi
|
||||||
|
.PP
|
||||||
|
To test it, run:
|
||||||
|
.nf
|
||||||
|
|
||||||
|
make test
|
||||||
|
.fi
|
||||||
|
.PP
|
||||||
|
To install it, run:
|
||||||
|
.nf
|
||||||
|
|
||||||
|
make install
|
||||||
|
.fi
|
||||||
|
.PP
|
||||||
|
If you want a shared library, run:
|
||||||
|
.nf
|
||||||
|
|
||||||
|
make all\-shared
|
||||||
|
make install\-shared
|
||||||
|
.fi
|
||||||
|
.PP
|
||||||
|
The default installation location is "/usr/local". Pass the prefix variable to make to install it to another location:
|
||||||
|
.nf
|
||||||
|
|
||||||
|
make install prefix=/some/other/directory
|
||||||
|
.fi
|
||||||
|
.PP
|
||||||
|
The makefile installs the pdfio header to "${prefix}/include", the library to "${prefix}/lib", the pkg\-config file to "${prefix}/lib/pkgconfig", the man page to "${prefix}/share/man/man3", and the documentation to "${prefix}/share/doc/pdfio".
|
||||||
|
.PP
|
||||||
|
The makefile supports the following variables that can be specified in the make command or as environment variables:
|
||||||
|

.SS Visual Studio Project
|
||||||
|
.PP
|
||||||
|
Note: I haven't yet added this...
|
||||||
|
|
||||||
|
.PP
|
||||||
|
The Visual Studio solution ("pdfio.sln") is provided for Windows developers generates both a static library and DLL.
|
||||||
|
.SS Xcode Project
|
||||||
|
.PP
|
||||||
|
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:
|
||||||
|
.nf
|
||||||
|
|
||||||
|
sudo xcodebuild install
|
||||||
|
.fi
|
||||||
|
.PP
|
||||||
|
You can reproduce this with the makefile using:
|
||||||
|
.nf
|
||||||
|
|
||||||
|
sudo make 'COMMONFLAGS="\-Os \-mmacosx\-version\-min=10.14 \-arch x86_64 \-arch arm64"' install
|
||||||
|
.fi
|
||||||
|
.SS Detecting PDFio
|
||||||
|
.PP
|
||||||
|
PDFio can be detected using the pkg\-config command, for example:
|
||||||
|
.nf
|
||||||
|
|
||||||
|
if pkg\-config \-\-exists pdfio; then
|
||||||
|
...
|
||||||
|
fi
|
||||||
|
.fi
|
||||||
|
.PP
|
||||||
|
In a makefile you can add the necessary compiler and linker options with:
|
||||||
|
.nf
|
||||||
|
|
||||||
|
CFLAGS += `pkg\-config \-\-cflags pdfio`
|
||||||
|
LIBS += `pkg\-config \-\-libs pdfio`
|
||||||
|
.fi
|
||||||
|
.SS Header Files
|
||||||
|
.PP
|
||||||
|
PDFio provides a primary header file that is always used:
|
||||||
|
.nf
|
||||||
|
|
||||||
|
#include <pdfio.h>
|
||||||
|
.fi
|
||||||
|
.PP
|
||||||
|
PDFio also provides content helper functions that are defined in a separate header file:
|
||||||
|
.nf
|
||||||
|
|
||||||
|
#include <pdfio\-content.h>
|
||||||
|

|
||||||
|
<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>

||||||
|
<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>
|

|
<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>
|
||||||
|

Requirements
|
||||||
|
------------
|
||||||
|
|
||||||
|
PDFio requires the following to build the software:
|
||||||
|
|
||||||
|
- A C99 compiler such as Clang, GCC, or MS Visual C
|
||||||
|
- A POSIX-compliant `make` program
|
||||||
|
- ZLIB (<https://www.zlib.net>) 1.0 or higher
|
||||||
|
|
||||||
|
IDE files for Xcode (macOS/iOS) and Visual Studio (Windows) are also provided.
|
||||||
|
|
||||||
|
|
||||||
|
Installing pdfio
|
||||||
|
----------------
|
||||||
|
|
||||||
|
PDFio comes with a portable makefile that will work on any POSIX-compliant
|
||||||
|
system with ZLIB installed. To make it, run:
|
||||||
|
|
||||||
|
make all
|
||||||
|
|
||||||
|
To test it, run:
|
||||||
|
|
||||||
|
make test
|
||||||
|
|
||||||
|
To install it, run:
|
||||||
|
|
||||||
|
make install
|
||||||
|
|
||||||
|
If you want a shared library, run:
|
||||||
|
|
||||||
|
make all-shared
|
||||||
|
make install-shared
|
||||||
|
|
||||||
|
The default installation location is "/usr/local". Pass the `prefix` variable
|
||||||
|
to make to install it to another location:
|
||||||
|
|
||||||
|
make install prefix=/some/other/directory
|
||||||
|
|
||||||
|
The makefile installs the pdfio header to "${prefix}/include", the library to
|
||||||
|
"${prefix}/lib", the `pkg-config` file to "${prefix}/lib/pkgconfig", the man
|
||||||
|
page to "${prefix}/share/man/man3", and the documentation to
|
||||||
|
"${prefix}/share/doc/pdfio".
|
||||||
|
|
||||||
|
The makefile supports the following variables that can be specified in the make
|
||||||
|
command or as environment variables:
|
||||||
|
|
||||||
|
- `AR`: the library archiver (default "ar")
|
||||||
|
- `ARFLAGS`: options for the library archiver (default "cr")
|
||||||
|
- `CC`: the C compiler (default "cc")
|
||||||
|
- `CFLAGS`: options for the C compiler (default "")
|
||||||
|
- `CODESIGN_IDENTITY`: the identity to use when code signing the shared library
|
||||||
|
on macOS (default "Developer ID")
|
||||||
|
- `COMMONFLAGS`: options for the C compiler and linker (typically architecture
|
||||||
|
and optimization options, default is "-Os -g")
|
||||||
|
- `CPPFLAGS`: options for the C preprocessor (default "")
|
||||||
|
- `DESTDIR" and "DSTROOT`: specifies a root directory when installing
|
||||||
|
(default is "", specify only one)
|
||||||
|
- `DSOFLAGS`: options for the C compiler when linking the shared library
|
||||||
|
(default "")
|
||||||
|
- `LDFLAGS`: options for the C compiler when linking the test programs
|
||||||
|
(default "")
|
||||||
|
- `LIBS`: library options when linking the test programs (default "-lz")
|
||||||
|
- `RANLIB`: program that generates a table-of-contents in a library
|
||||||
|
(default "ranlib")
|
||||||
|
- `prefix`: specifies the installation directory (default "/usr/local")
|
||||||
|
|
||||||
|
|
||||||
|
Visual Studio Project
|
||||||
|
---------------------
|
||||||
|
|
||||||
|
> Note: I haven't yet added this...
|
||||||
|
|
||||||
|
The Visual Studio solution ("pdfio.sln") is provided for Windows developers
|
||||||
|
generates both a static library and DLL.
|
||||||
|
|
||||||
|
|
||||||
|
Xcode Project
|
||||||
|
-------------
|
||||||
|
|
||||||
|
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:
|
||||||
|
|
||||||
|
sudo xcodebuild install
|
||||||
|
|
||||||
|
You can reproduce this with the makefile using:
|
||||||
|
|
||||||
|
sudo make 'COMMONFLAGS="-Os -mmacosx-version-min=10.14 -arch x86_64 -arch arm64"' install
|
||||||
|
|
||||||
|
|
||||||
|
Detecting PDFio
|
||||||
|
---------------
|
||||||
|
|
||||||
|
PDFio can be detected using the `pkg-config` command, for example:
|
||||||
|
|
||||||
|
if pkg-config --exists pdfio; then
|
||||||
|
...
|
||||||
|
fi
|
||||||
|
|
||||||
|
In a makefile you can add the necessary compiler and linker options with:
|
||||||
|
|
||||||
|
```make
|
||||||
|
CFLAGS += `pkg-config --cflags pdfio`
|
||||||
|
LIBS += `pkg-config --libs pdfio`
|
||||||
|
```
|
||||||
|
|
||||||
|
|
||||||
|
Header Files
|
||||||
|
------------
|
||||||
|
|
||||||
|
PDFio provides a primary header file that is always used:
|
||||||
|
|
||||||
|
```c
|
||||||
|
#include <pdfio.h>
|
||||||
|
```
|
||||||
|
|
||||||
|
PDFio also provides content helper functions that are defined in a separate
|
||||||
|
header file:
|
||||||
|
|
||||||
|
```c
|
||||||
|
#include <pdfio-content.h>
|
||||||
|
```
|
||||||
|
|
||||||
|
|
||||||
|
API Overview
|
||||||
|
============
|
||||||
|
|
||||||
|
PDFio exposes several types:
|
||||||
|
|
||||||
|
- `pdfio_file_t`: A PDF file (for reading or writing)
|
||||||
|
- `pdfio_array_t`: An array of values
|
||||||
|
- `pdfio_dict_t`: A dictionary of key/value pairs in a PDF file, object, etc.
|
||||||
|
- `pdfio_obj_t`: An object in a PDF file
|
||||||
|
- `pdfio_stream_t`: An object stream
