2014-02-07 02:07:03 +00:00
* [Cairo](http://cairographics.org) is a graphics
* library that supports vector graphics and image compositing that
2011-02-09 07:43:07 +00:00
* can be used with GDK. GTK+ does all of its drawing using cairo.
*
2011-02-09 07:43:07 +00:00
* GDK does not wrap the cairo API, instead it allows to create cairo
2010-10-12 14:53:44 +00:00
* contexts which can be used to draw on #GdkWindows. Additional
* functions allow use #GdkRectangles with cairo and to use #GdkColors,
2011-02-09 07:43:07 +00:00
* #GdkRGBAs, #GdkPixbufs and #GdkWindows as sources for drawing
* operations.
