ABSTRACT:
Digital information representing a displayable image is selectively modified to create various rotation effects, including rotations of the viewed image about various lines in its display plane and angular rotations within that plane. In the modification process, the information is moved between source and destination areas in a data processing system memory, without requiring intermediate buffer storage of the information during the process and therefore without requiring additional processing steps associated with intermediate buffer storage. The source and destination areas are of equal size and may overlap. This technique is applicable to document scanning apparatus as well as computer display apparatus.
