Image handling facilitating computer aided design and manufacture of documents
First Claim
1. Apparatus for handling digital representations of documents which are to be provided with one or more images, the apparatus comprising a first store for storing digital data defining the image content of each pixel of each image;
- color data generating means for generating data defining the color of each pixel of each image or combination of images as defined by a user, separate from the image content data; and
processing means for selectively combining the image content data and color data to enable selected images to be viewed separately or in combination, wherein the color data generating means comprises a second store in the for of a look-up table which has an address corresponding to each possible combination of images within a pixel and contains at each address color data defining the resultant pixel color.

Abstract
Apparatus for handling digital representations of documents which are to be provided with a number of images. The apparatus comprises a first store for storing digital data defining the image content of each pixel of each image and a color generator for generating data defining, independently of the image contact data, the color of each pixel of each image or combinations of images as defined by a user. A processor selectively combines the image content data and the color data to enable selected images to be viewed separately or in combination as allowed by the layering structure provided.
