METHODS, APPARATUS, AND DATA STRUCTURES FOR ACCESSING SUB-PIXEL DATA HAVING LEFT SIDE BEARING INFORMATION

摘要

Techniques for accessing oversampled sub-pixels (1104), also referred to as 'source sub-pixels', such that the blocks (C1, C2, C3) of source sub-pixels to be accessed are shifted (C1, C2, C3) to account for a left side bearing remainder (1430) in the final display (1203) of the character (1208). The source sub-pixels (1104) are accessed, efficiently, in blocks (or chunks) corresponding to the over-sampling rate.
