Cairo - Multi-platform 2D graphics library
|
|
http://cairographics.org
|
|
|
|
What is cairo
|
|
=============
|
|
Cairo is a 2D graphics library with support for multiple output
|
|
devices. Currently supported output targets include the X Window
|
|
System, OpenGL, and win32 as well as image buffers. Experimental
|
|
backends include Quartz and XCB as well as PostScript and PDF files.
|
|
|
|
Cairo is designed to produce consistent output on all output media
|
|
while taking advantage of display hardware acceleration when available
|
|
(eg. through the X Render Extension).
|
|
|
|
The cairo API provides operations similar to the drawing operators of
|
|
PostScript and PDF. Operations in cairo including stroking and filling
|
|
cubic Bézier splines, transforming and compositing translucent images,
|
|
and antialiased text rendering. All drawing operations can be scaled,
|
|
rotated, or transformed through any other affine transformation.
|
|
|
|
Cairo has been designed to let you draw anything you want in a modern
|
|
2D graphical user interface. At the same time, the cairo API has been
|
|
designed to be as easy to learn and fun to use as possible. If you're
|
|
not having fun while programming with cairo, then we have failed
|
|
somewhere---let us know and we'll try to fix it next time around.
|
|
|
|
Cairo is free software and is available to be redistributed and/or
|
|
modified under the terms of either the GNU Lesser General Public
|
|

Compiling
|
|
=========
|
|
See the INSTALL document for build instructions.
|
|
|
|
History
|
|
=======
|
|
Cairo was originally developed by Carl Worth <cworth@cworth.org> and
|
|
Keith Packard <keithp@keithp.com>. Many thanks are due to Lyle Ramshaw
|
|
without whose patient help our ignorance would be much more apparent.
|
|
|
|
Since the original development, many more people have contributed to
|
|
cairo. See the AUTHORS files for as complete a list as we've been able
|
|
to compile so far.
