Abstract

A system, a method and computer-readable media for rendering text with a graphics processing unit (GPU). The system, method, and media includes a GPU that may be configured to receive a plurality of compressed glyph bitmap and create a plurality of glyph textures from the bitmap. The GPU may be further configured to pack a plurality of rows of data from a glyph bitmap into a single row of a glyph texture. The GPU may be also be configured to merge the plurality of glyph textures into a merged texture to identify overlapping rows of color. Additionally, the GPU maybe configured to filter the merged texture to create a grayscale texture containing a plurality of merged glyphs and rendering the grayscale texture to display the plurality of merged glyphs.
