Abstract
An electronic graphic system for use in the painting of an image comprises a control store which stores control data representing a distribution of interpolation coefficients. The control data is created in a drawing process in which existing control data in the store is compared with new control data and is replaced with the new data when the new data has a value higher than that of the existing data. A combiner, in response to the stored control data, combines initial image data from an framestore with user selected color data from a store for display on a monitor. Also, the combiner can be reconfigured such that the combined data is written to the framestore replacing the initial image data therin. The system thus separates drawing operations from image modification operations, thereby providing a flexible means by which a simple binary line drawing algorithm can be used to paint into a color image.
