Does anyone know a way to convert a bitmap to monochrome, where any pixel color other than the background color is made black? Here's why (so I don't get 10 messages telling me to d/l paint shop pro :). I'm trying to make it so you can put a bitmap onto an image list, but since the image lists in win32lib use masks, I need to generate a mask. I've been using CopyImage (in user32.dll), with the LR_MONOCHROME flag sent, but it fails to convert most of the colors, which means that the image isn't very good. Matt Lewis
