Abstract
A method and apparatus for using composite transforms to efficiently produce intermediary image data metrics that are independent of the input image origins. The method and apparatus produce intermediary image data metrics that can be used to drive the output of any of a plurality of image-receptive media or image-forming devices such that the reproduced images appear appropriately rendered for the output medium or device chosen regardless of the input image origin. The intermediary image data metrics may also be stored for later use without requiring documentation of their origin; images or portions thereof from various media and devices may be merged together to produce composite images of homogeneous and appropriate appearance; and images may be balanced and otherwise manipulated without requiring references to their origin.
