Add some historical notes on cairo development, prior to when we began to maintain this NEWS file. Add pointer to cairographics.org. Fix to use cairo rather than Cairo when not at the beginning of a sentence. Remove cairo_current_path, cairo_current_path_flat, cairo_text_extents, cairo_glyph_extents, cairo_text_path, and cairo_glyph_path from the TODO list as they have all been implemented now.

Cairo - Multi-platform 2D graphics library
|
|
http://cairographics.org
|
|
|
|
Compiling
|
|
---------
|
|
See the INSTALL document for build instructions.
|
|
|
|
Description
|
|
-----------
|
|
Cairo is a vector graphics library with cross-device output
|
|
support. Currently supported output targets include the X Window
|
|
System and in-memory image buffers. PostScript and PDF file output is
|
|
planned. Cairo is designed to produce identical output on all output
|
|
media while taking advantage of display hardware acceleration when
|
|
available (eg. through the X Render Extension).
|
|
|
|
Cairo provides a stateful user-level API with capabilities similar to
|
|
the PDF 1.4 imaging model. Cairo provides operations including
|
|
stroking and filling Bezier cubic splines, transforming and
|
|
compositing translucent images, and antialiased text rendering.
|
|
|
|
Cairo was once named Xr, (or Xr/Xc), so if you came looking for that
|
|
software, you've found it.
|
|
|
|
Dependencies
|
|
------------
|
|
Cairo currently requires the following supporting libraries:
|
|
|
|
libpixman
|
|
Xft2
|
|
fontconfig
|
|
freetype2
|
|
|
|
Documentation
|
|
-------------
|
|
There's not much documentation yet apart from the cairo.h header
|
|
file. We'll be correcting that shortly.
|
|
|
|
In the meantime, the cairo-demo module in CVS provides a few example
|
|
programs using cairo. These may be helpful to a programmer just
|
|
beginning with cairo. Also, familiarity with the PostScript imaging
|
|
model will help in understanding cairo.
|
|
|
|
History
|
|
-------
|
|
Cairo was originally developed by Carl Worth <cworth@isi.edu> and
|
|
Keith Packard <keithp@keithp.com>. Many thanks are due to Lyle Ramshaw
|
|
without whose patient help our ignorance would be much more apparent.

improved, please feel free to send a message to cairo@cairographics.org

Cairo is still under active development and all discussion happens on
|
|
that list. So if you want to lurk or, (even better), take part in the
|
|
development, take a look. Subscription information and archives are
