ABSTRACT:
An apparatus for electronically modifying the appearance of an image stored in the form of digital data defining the color content of the image comprises a store (8) for storing sets of coordinates defining positions around the edge of the image and, for each set of coordinates, storing the characteristics of an electronic painting tool including the profile of the tool. A monitor (30) displays the image. A processor (1, 15-19) compares the current position of the tool with the sets of stored coordinates and when the tool is at or in the region of a set of stored coordinates changes the tool characteristics to those previously determined for that set of coordinates.
