ABSTRACT:
An irreversible compression system and method, includes fetching cells of bit map data from first and second adjacent blocks of bit map data, each of the fetched cells having a predetermined cell size, and each of the fetched cells is converted to compressed code. When the size of the first block of bit map data is indivisible by the predetermined cell size, a first incomplete cell having a first reduced size is fetched from the first block and a second incomplete cell is fetched from the second block, the second incomplete cell being adjacent the first incomplete cell and having a second reduced size such that the sum of the first reduced size and the second reduced size is equal to the predetermined cell size.
