Abstract
The invented blank strip compression method recognizes that different font characters may have strips of blank data. For example, in the character '.sub.-- ' 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.
