Abstract

PURPOSE:To quickly perform the rotation processing of a rectangular picture by using drawing start coordinates from a circuit which automatically calculates and generates drawing start coordinates of each line constituting the rectangular picture to be rotated in accordance with rotation parameters. CONSTITUTION:Drawing start coordinates from the circuit which automatically calculates and generates drawing start coordinates of each line constituting a rectangular picture S to be rotated in accordance with rotation parameters DELTADX and DELTADY are used to successively perform the rotation processing of each line of the rectangular picture in response to one picture rotation start instruction, thereby drawing the rectangular picture to be rotated. Thus, it is unnecessary that drawing start coordinates of each line of a rectangular picture D to be rotated are calculated by a software program at the time of rotation processing of each line, and it is unnecessary that the rotation start indication in issued at the time of calculating drawing start coordinates of each line to start drawing by the software program, and the rotation processing is quickly performed.
