George,

I've got a book here Supercharged Bitmapped Graphics, by Steve Rimmer, ISBN 0-8306-3788-5 that has about 50 pages of text/code covering Windows image formats. All the rest of them I have go back to the days when we got to twiddle bits ourselves in EGA/VGA memory *s* I assume you've checked some of the sample code on MSDN?

>Well, I finally got it for 256 and 24 bit color (sort of). 256 is fine. 24 bit is another story. Part of it I think is the color mask I mentioned earlier in this thread. I think that the bits are either XORed or ORed with the mask. I saw it somewhere in the SDK.

>The odd thing is that the left 20 pixels (frame plus scroll bar width) are moved to the right side of the image when trying to do 24 bit color. Really odd. I think it's something either with CreateDIBSection(), BitBlt() or GetDIBits(), but what I have no idea.
