Patent attributes
Embodiments of the invention relate to an image or raster compression method that includes receiving pixel data for a raster comprising a two dimensional (2D) array of pixels where each pixel is associated with a data value. The method further includes receiving a user defined parameter defining a maximum error allowable per pixel for a compression algorithm. The raster can be divided into a number of pixel blocks where each pixel can be quantized and bit stuffed based on a number of block statistics including the maximum error allowable. The method further includes executing the compression algorithm wherein for each pixel, where an error caused by the compression algorithm is equal to or less than the maximum error allowable, and encoding the pixel data based on the compression algorithm. In certain embodiments, the compression algorithm is a non-transform compression algorithm.
