[net.graphics] Fast colour anti-aliasing - determining new pixel colours

parker@mprvaxa.UUCP (Ross Parker) (02/20/86)

Does anyone out there know of a fast (or even a slow) algorithm for
colour anti-aliasing? The actual problem is to shrink a colour
raster image, and I need to know how to calculate the colours of the
pixels in the new image, which (I would imagine) is similar to calculating
pixel colours for anti-aliasing. 

Any algorithms, references, ideas, etc. would be much appreciated.

Thanks in advance for any help you can give me.
