How to dither a 256 greyscale bitmap to b/w
Posted on 1999-11-01
I need to programmatically dither a 256 grey scale bitmap to 1-bit (black and white) in a borland pascal for windows version 7.0 application.
I've seen the functions I want in Paint-Shop pro, when you do colour reduction. There you can do ordered dithering, and a number of types of error diffusion.
Does anybody know of any 16-bit graphic libraries that have functions like these?
