[cairo] Examples of raster output

being a happy user of the vector outputs Cairo generates, I am looking 
now to generate (optimised) raster outputs, such as GIF, JPEG, but 
especially PNG. Conversion programs, such as Imagemagick convert, take 
much too long.

I wondered if there is any documentation/examples out there using libpng 
and libgif from Cairo outputs? Are there ways to easily extend the png 
output from Cairo to 8bit colour depth?

Thanks in advance
