<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
|
|
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 <ulink url="http://en.wikipedia.org/wiki/Affine_transformation">affine
|
|
transformation</ulink> (scale, rotation, shear, etc.).</para>

installing the desired package(s), then installing cairo again. As the test

suite seems to be somewhat broken it doesn't seem worth the effort.</para>
