Patent abstract
Embodiments of the invention relate to an image or raster compression method for a multi-dimensional array of pixels. A user specifies a maximum error allowable per pixel for the compression algorithm. The raster is divided into a number of pixel blocks where each pixel is quantized and bit stuffed based on a number of block statistics including the maximum error allowable. The size of the pixel blocks is limited to two (e.g., 8×8 and 16×16) to save processing time with little difference in compression. A Look-Up Table (LUT) is used instead for certain types of data where it is more efficient.
