How Cairo library works?


Hello! There are a lot of good docs about Cairo API, but nothing about realization. I want to understand the principles of drawing and such advances thing as anti-aliasing, translucency, etc. Can anyone help me in it.
Thanks

AFAIK is Cairo just drawing vectors onto some surface which in case of translucency has to be an ARGB-capable surface - a PNG with an alpha channel or some composited X window.


Basic documentation and many links:

http://www.cairographics.org/documentation/

http://www.cairographics.org/samples/

Examples of compositing/transparency (very useful):
