Graphics and Interaction

A file, or an area of memory which is used to store a picture. The important features of a bitmap are its width, height and colour depth; shape information is held in a bitmap’s mask.

EPOC bitmaps are stored in multi-bitmap files (MBMs), which contain one or more bitmaps. MBMs are indexed by ID number.
