ABSTRACT:
An image layout processing method for simulating on a display screen an arrangement of a plurality of image objects to be transferred to a prepress mechanical. An image memory plane is divided into a ground area, a key object area, and a display work area. A plurality of objects other than a key object fetched from an external storage are written as priority data to the ground area in an order of priority for superposition of the objects. Data of a selected key object are written to the key object area. The data in the ground area are unconditionally copied to the display work area, while the data in the key object area are copied to a designated position in the display work area with a condition based on a designated priority. Respective pixel data successively read from the display work area are converted by a lookup table into color data to be displayed on a cathode ray tube (CRT) whereby the key object is presented as inserted between desired objects.
