Abstract:
1. One or more computer-readable storage media having computer-useable instructions embodied thereon to perform, by execution by at least one computing device having at least one processor and at least one memory, a method for rendering glyphs, the method comprising: receiving a plurality of compressed glyph bitmaps having a first color depth; decompressing, by said at least one processor, at least a portion of the plurality of compressed glyph bitmaps to create a plurality of glyph textures having a second color depth, wherein the decompressing includes packing a plurality of rows of data from a glyph bitmap into a single row of a glyph texture, wherein the single row includes a plurality of sub-rows of color data; merging the plurality of glyph textures into a merged texture to identify overlapping rows of color data; filtering 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.
