| 31 | <application>Cairo</application> is a 2D graphics library with support for
|
---|
| 32 | multiple output devices. Currently supported output targets include the
|
---|
[1fc53421] | 33 | <application>X</application> Window System, Win32, image buffers,
|
---|
[521cea0] | 34 | PostScript, PDF and SVG. Experimental backends include OpenGL, Quartz and
|
---|
[68d01360] | 35 | XCB file output. <application>Cairo</application> is designed to produce
|
---|
| 36 | consistent output on all output media while taking advantage of display
|
---|
| 37 | hardware acceleration when available (e.g., through the X Render
|
---|
| 38 | Extension). The <application>Cairo</application> API provides operations
|
---|
| 39 | similar to the drawing operators of PostScript and PDF. Operations in
|
---|
[521cea0] | 40 | <application>Cairo</application> include stroking and filling cubic
|
---|
| 41 | Bézier splines, transforming and compositing translucent images,
|
---|
| 42 | and antialiased text rendering. All drawing operations can be transformed
|
---|
