    <title>Introduction to cairo</title>

    <para><application>cairo</application> is a 2D graphics library with
    support for multiple output devices. Currently supported output targets
    include the <application>X</application> Window System, win32, and image
    buffers. Experimental backends include OpenGL (through glitz), Quartz,
    XCB, PostScript and PDF file output. cairo is designed to produce
    consistent output on all output media while taking advantage of display
    hardware acceleration when available (e.g., through the X Render
    Extension). The <application>cairo</application> API provides operations
    similar to the drawing operators of PostScript and PDF. Operations in
    <application>cairo</application> include stroking and filling cubic
    Bézier splines, transforming and compositing translucent images, and
    antialiased text rendering. All drawing operations can be transformed by
    any affine transformation (scale, rotation, shear, etc.).</para>

    <title>Installation of cairo</title>

    <para><application>cairo</application> will look for an
    <application>X Render</application> <application>pkg-config</application>
    file. If you use <application>XFree86</application> as your
    <application>X</application> Window system, ensure this file exists
    (<filename>/usr/X11R6/lib/pkgconfig/xrender.pc</filename>). Instructions to
    create this file have just recently been added to the BLFS book, so you may
    need to go back to the <application>XFree86</application> section to create
    it.</para>

    <para>Install <application>cairo</application> by running the following
    commands:</para>

<screen><userinput>sed -i -e 's/type == GLITZ/color.fourcc == GLITZ/' \
       -e 's/FORMAT_TYPE_COLOR/FOURCC_RGB/' \
    src/cairo-glitz-surface.c &amp;&amp;
./configure --prefix=/usr &amp;&amp;
make</userinput></screen>

    <para>To test the results, issue: <command>make check</command>.</para>

    <para>Now, as the <systemitem class="username">root</systemitem> user:</para>

    This command (copied from upstream CVS) fixes a build problem if you link
    <application>glitz</application> into the build by passing
    <option>--enable-glitz</option> to the <command>configure</command>
    script.</para>
