<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>
