Abstract (en)

[origin: WO0013144A1] A computer-implemented method of preparing an image for graphical display. The image has a high spatial frequency component and a low spatial frequency component. The method includes receiving a scanned representation of the image and extracting the high spatial frequency component and the low spatial frequency component from the scanned representation of the image. The method also includes compressing the high spatial frequency component using a spatially lossless compression technique and compressing the low spatial frequency component using a spatially lossy compression technique.
