Is there anyway to display a 24bpp DIB on a 256 color SVGA without
implementing the code for color quantization? I wrote some code to
convert 24bpp images into 8bpp DIBs, but it takes around 10 seconds
for a 512x512 DIB, and I just wonder if there is a better way.
I did try using SetDIBitsToDevice, but the picture only uses the 20
system colors to draw the 24bpp DIB. The result is pretty nasty looking.
So, I would be intereseted in hearing how other people got around the
problem of using 24bpp DIBs on a 256 color system. Thanks!
