ABSTRACT:
A method and system for increasing efficiency in the display of characters on a display within a data processing system, wherein the data processing system includes a system memory and a graphics adapter, the system memory having a page mode. A plurality of characters are stored in the system memory as a plurality of glyph bitmaps. Each character has a width, and each glyph bitmap for a character is arranged as a plurality of scanlines such that each of the scanlines includes the width of the character. Selected glyph bitmaps are transmitted from the system memory to the graphics adapter, wherein an occurrence of breaks in the page mode are minimized when the selected glyph bitmaps are moved from the system memory to the graphics adapter, increasing efficiency in displaying characters on a display.
