Visual Help uses inline bitmaps and full-screen bitmaps. The following table shows the characteristics of these bitmaps.

All bitmaps must use the eight-color palette supported by an Auto PC display. However, they must be saved as 16-color bitmaps; this includes monochrome (black and white) bitmaps. The following table shows the supported colors and their common uses.
