    摘要: The present invention relates to the field of computer technology, and in particular to a method and system for compressing digital data from a row-column structured, multi-color bitmap image representation and to advantageous applications thereof for low bandwidth data communication. In order to increase the compression rate in particular of bitmaps corresponding to screen shots in web-based applications or standard desktop applications having a graphical user interface (GUI) it is proposed to reduce (210) the image representation in order to contain only a subset of colors, preferably 2, 4, 8, 16 . . . 256, before subjecting it to further compression steps (215, 260, 265) and comprising rowwise X-OR operations (215) and subsequent compressed mapping (240, 245) of the resulting pixel information into a respective compressed bit string. X-OR operations in column direction (220) are also added in order to improve the compression rate for the specific field of above said low bandwidth communications.
