Abstract: A computer program is used to compress color graphics animation sequences for local storage and transmission to remotely networked sites in a significantly reduced size It allows playback of these animations on a wide variety of workstations ranging from personal computer class machines to high end scientific and engineering workstations such as Sun and Silicon Graphics machines. The basic raster image to be compressed is full color with 24-bits per pixel. The compressed form of a raster image is such that the original image can be reconstructed exactly, with no loss of information, on the same computer that compressed it (typically a large mainframe supercomputer) or on the smaller scientific or engineering workstation. A precompression conversion to palette form of a full color image is possible if the computer on which the reconstruction and display is to take place has limited color capabilities; this is the case for lower cost personal computers and workstations.
