If I save a 24-bit DIB as .BMP-file it's about 1.8 MB large. I don't have so much colors in the DIB so it gives also enough good results to reduce to 4-bit colors. I tried it with MS-PAINT. MS-Paint allows you to convert to 4 bit and the result is very good and the file-size reduces to nearly 300 kB. Is there anywhere source-code in VC++ in doing this converting from own programs written in C++ ?
Thanks a lot
