An improved method and associated mechanism for facilitating the transformation of digitized images intended for use in a multi-resolution, multi-application environment by performing complex transformations on low resolution image components and approximate transformations on the high level image components so as to reduce computational complexity. In a preferred embodiment of the invention, the transformation operator is executed upon a relatively low spatial resolution file, thereby resulting in a substantial reduction in processing overhead. Advantage is thus taken of the availability of the reduced size of the lower spatial resolution base file within the hierarchical database, so that a relatively complex conversion may be performed on a 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*3072 pixel image for driving a high resolution digital thermal color printer.
