Abstract
A method and apparatus for horizontally expanding a video graphics adapter (VGA) text character display image to fully fill the screen of a flat panel display. Cell lines for each character are remapped to provide expanded cell lines. The flat panel apparatus includes a video memory for storing the character code, attribute data and font data, a character generator for generating character font data based on the character code, a lookup table for providing expanded cell lines, and an attribute controller for combining the font data and the attribute data for output to a flat panel display.
Claims10
A graphics adapter comprising:
- a character generator to generate character font data based on a character code;
- a map table coupled to said character generator, said map table containing one or more mappings such that when said character font data is received from said character generator, one of said one or more mappings is applied to said character font data to produce a horizontal expansion pattern;
- and
- a buffer coupled to said map table, wherein said buffer appends said horizontal expansion pattern to a sequence of horizontal expansion patterns representing a scan line.
