    PDFio is not concerned with rendering or viewing a PDF file, although a PDF RIP or viewer could be written using it.

    +

    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.

    +

    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:

    +
    CFLAGS  +=      `pkg-config --cflags pdfio`
+LIBS    +=      `pkg-config --libs pdfio`
+
    +

    Header Files

    +

    PDFio provides a primary header file that is always used:

    +
    #include <pdfio.h>
+
    +

    PDFio also provides content helper functions that are defined in a separate header file:

    +
    #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

      +
      • +
