US 2003/0169268 A1 · System and method for performing font operations when background color is transparent

Abstract

One embodiment of a method of performing a font operation involves receiving a set of font data identifying a font operation to be performed. If a first font data unit in the set indicates that a first coordinate should be a background color and transparent background is enabled, the method involves outputting an enable for a second font data unit in the set. The second font data unit indicates that a second coordinate should be a foreground color. The enable for the second coordinate is output instead of a disable for the first coordinate. If instead the first font data unit in the set indicates that the first coordinate should be a background color and transparent background is disabled, the method may involve outputting a disable for the first coordinate.

Dependent claims

A graphics system comprising:

a buffer;
a font processor configured to receive a set of font data, wherein if a background color is transparent and a first font data unit associated with a first coordinate indicates that the first coordinate should be the background color, the font processor is configured to generate an enable for a second font data unit that indicates that a second coordinate should be a foreground color instead of generating a disable for the first coordinate;
and
a fragment processor coupled to access the buffer, wherein the fragment processor is coupled to receive the enable from the font processor and to responsively write an element at the second coordinate into the buffer, wherein the element at the second coordinate is the foreground color.
