When I wrote this function my problem was to replace one color by an other on transparent bitmaps. My images were resources bitmaps, which I store in an ImageList for easy transparency.
There is no easy way to directly access a Bitmap s pixel on Win32. If you re interested in, this article may help you to understand the usage of CreateDIBSection.
If you have to load a bitmap from resource and made many color replacements, or if you have to change a color in a HBITMAP this function is for you.
If you have a bitmap in resource and want to replace one or more color on load, it s better to use CreateMappedBitmap. You can found in the sample program a ReplaceColor function which use CreateMappedBitmap.
I ve made the same code using only BitBlt. All BitBlt are really fast but the creation of the mask bitmap is so slow than the whole function is twice slower than the code using CreateDIBSection. ( sources are in the sample )
