Abstract:
A process for rapidly decoding and displaying formatted original raster images on a computer display device with negligible delay time, comprising the steps of:receiving a self contained stream of formatted digital scan line data at the computer comprising a raster image to be displayed on a display;reading image input parameters contained in said stream of scan line data to enable the computer to format the scan line data into an original pixel image;decoding and dividing the raster image into a number of fixed sized strips S of scan lines of pixel data wherein each pixel is defined by said image input parameters;generating an original pixel image as a plurality of pixel image rows from said fixed size strips of data in said computer;storing pixel image rows in the form of said fixed sized strips in a memory in said computer,generating a scaling map in said computer which relates the pixel positions of said fixed sized strips of pixel image rows with actual pixel positions of said computer display device;processing each of said fixed sized strips of pixel image rows individually using said scaling map to expand or shrink each of said fixed sized strips to predetermined display scan lines of an image of pixels compatible with said display device; anddisplaying each of said decoded scaled and processed fixed sized pixel image strips as they are processed as pixel display scan lines on said display device of said computer immediately after said scaled strips are individually processed.
