Abstract
In a system for compressing, decompressing, and logically manipulating arbitrary bit-maps, the bit-map is aligned along byte boundaries. Each aligned byte is classified as a gap byte if all of the bits of the byte store the same logical value, otherwise the byte is classified as a non-gap byte. Adjacent bytes of the same class are grouped. Groups of gap bytes are encoded into an atomic sequence of bytes as a count of the number of bits included in the grouped gap bytes. Map bytes are duplicated in the atomic sequence and also associated with a count thereof.
