BMPs *are* DIBs. DIB format is for bitmapped images that are written to files so they can be transferred around and also be converted to other formats. BMPs in *memory* can either be DIBs or DDBs (Device Dependent Bitmaps). DDBs get rendered using the current palette (if not 24 bit) and the palette is subject to change depending on what else is running and whether or not the image is in the background or foreground. Perhaps you've noticed the psychedelic effect when several images are displayed in a 256 color mode. The foreground image is rendered as close as possible to its colors causing the background images to have some of their colors remapped. -- ________________________________________________________________________________ R.
