Definitions for "Bit-mapped"
Keywords:  pixel, kbytes, gray, apa, shade
A term used to describe images composed of patterns of dots and displayed on graphics computer screens.
Images that are formed from pixels and each pixel being a shade of gray or another color.
A bit-mapped display is one in which the screen display (characters and/or graphics and/or image) is generated or retrieved from a full representation in memory (the bit map). The bit map contains a bit for each point of the screen display which enables high resolution screens to be displayed rapidly and accurately, but at the expense of a lot of memory (e.g., a VGA/2 screen with a resolution of 1024 x 768 pixels needs about 100KBytes of memory). Often used synonymously with APA.
