A data file or structure whichcorresponds bit for bit with an image displayed on ascreen, probably in the same format as it would be stored inthe display's video memory or maybe as a device independentbitmap. A bitmap is characterised by the width and height ofthe image in pixels and the number of bits per pixel whichdetermines the number of shades of grey or colours it canrepresent. A bitmap representing a coloured image (a"pixmap") will usually have pixels with between one andeight bits for each of the red, green, and blue components,though other colour encodings are also used. The greencomponent sometimes has more bits that the other two to caterfor the human eye's greater discrimination in this component.See also vector graphics, image formats.
