ABSTRACT:
An apparatus for and method of truncating images during data compression. The present invention truncates an image when the memory requirements for the compressed image exceeds a predetermined threshold. However, unlike prior art systems, the present invention contemplates replacing all of the pixels that are eliminated by the truncation process with a series of "0's" thereby "white filling" the truncated portion of the image. The present invention avoids the disadvantages in the prior art by ensuring that the truncated image contains the same number of pixels as a non-truncated image. Further, the data extent of the truncated image may be the same as a non-truncated image. Finally, the resulting images, either non-truncated images or, if necessary, truncated images, may be stored in a preselected memory size.
