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, win32, and image buffers. Experimental backends include OpenGL | |
(through glitz), Quartz, XCB, PostScript and PDF file output. | |
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 | |
transformed by any affine transformation (scale, rotation, shear, | |
etc.). | |
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 fun and easy to learn 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 | |
License (LGPL) version 2.1 or the Mozilla Public License (MPL) version | |
1.1. | |

Dependencies | |
============ | |
The set of libraries needed to compile cairo depends on which backends | |
are enabled when cairo is configured. Here are the dependencies for | |
each backend: | |
Surface backends: | |
image backend | |
------------- | |
no dependencies | |
glitz backend | |
------------- | |
glitz >= 0.4.4 http://freedesktop.org/Software/glitz | |
pdf backend | |
----------- | |
freetype >= 2.1.4 http://freetype.org | |
zlib http://www.gzip.org/zlib | |
postscript backend | |
------------------ | |
freetype >= 2.1.4 http://freetype.org | |
zlib http://www.gzip.org/zlib | |
quartz backend | |
-------------- | |
[*] | |
win32 backend | |
------------- | |
[*] | |
xcb backend | |
----------- | |
XCB http://xcb.freedesktop.org | |
xlib backend | |
------------ | |
Xrender >= 0.6 http://freedesktop.org/Software/xlibs | |
Font backends: | |
freetype font backend | |
--------------------- | |
freetype >= 2.1.4 http://freetype.org | |
fontconfig http://fontconfig.org | |
win32 font backend | |
------------------ | |
[*] | |
atsui font backend | |
------------------ | |
[*] | |
[*] I don't know specifically what packages might need to be | |
installed on a Mac OS X system to use the Quartz and ATSUI | |
backends. As far as win32, the situation is rather complex: | |
The Win32 backend should work on Windows 2000 and newer | |
(excluding Windows Me.) Most testing has been done on | |
Windows XP. While some portions of the code have been | |
adapted to work on older versions of Windows, considerable | |
work still needs to done to get cairo running in these | |
environments. | |
Cairo can be compiled on Windows either with the GCC | |
toolchain (see http://www.mingw.org) or with Microsoft | |
Visual C++. Makefiles or project files for compiling with | |
MSVC are however not provided as of this release. We have | |
received reports that MSVC 6.0 compiles parts of cairo | |
incorrectly, (leading to incorrect color). MSVC 7.0 is | |
known to work. | |
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. |
