30 | <title>Introduction to cairo</title>
|
---|
31 |
|
---|
32 | <para><application>Cairo</application> is a 2D graphics library with
|
---|
33 | support for multiple output devices. Currently supported output targets
|
---|
34 | include the <application>X</application> Window System, win32, image
|
---|
35 | buffers, PostScript, PDF and SVG. Experimental backends include OpenGL
|
---|
36 | Quartz and XCB file output. cairo is designed to produce consistent output
|
---|
37 | on all output media while taking advantage of display hardware acceleration
|
---|
38 | when available (e.g., through the X Render Extension). The
|
---|
39 | <application>Cairo</application> API provides operations similar to the
|
---|
40 | drawing operators of PostScript and PDF. Operations in
|
---|
41 | <application>Cairo</application> include stroking and filling cubic
|
---|
42 | Bézier splines, transforming and compositing translucent images, and
|
---|
43 | antialiased text rendering. All drawing operations can be transformed by
|
---|
44 | any <ulink url="http://en.wikipedia.org/wiki/Affine_transformation">affine
|
---|
