A mechanism for facilitating metric conver- sion of digitized images intended for use with a multi-resolution, multi-application environment is integrated into the encoding and decoding mechan- isms of the hierarchical database, such that stored residual image files contain metric change informa- tion. In a preferred embodiment of the invention, the metric conversion operator is executed upon a relatively low spatial resolution file, thereby result- ing in a substantial reduction in processing over- head, as advantage is taken of the availability of the reduced size of the lower spatial resolution base file within the hierarchical database, so that a met- ric conversion may be performed on the relatively small number of pixels within the base file, prior to up-converting the image to a relatively high spatial resolution image, such as a 2048 X 3072 pixel im- age for driving a high resolution digital thermal co- lor printer.
