    <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, image
    buffers, PostScript, PDF and SVG. Experimental backends include OpenGL
    (through glitz), Quartz and XCB 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>

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