Blank strip font compression method and device, and resulting stored, decompressible font

摘要

The invented blank strip compression method recognizes that different font characters may have strips of blank data. For example, in the character "-" the blank space above the character itself does not need to be stored in memory. The method identifies strips of blank and non-blank bit images that define characters and saves in memory only the bit images that are within the strips that include non-blank bit images resulting in a stored, decompressible font.
