ABSTRACT:
First parameters such as a main scanning repetition count, a subscanning repetition count, and the like are calculated in accordance with an instructed rotation angle. An arithmetic content according to the instructed rotation angle is read out from a memory for storing arithmetic contents for determining second parameters according to rotation angles, and the second parameter is calculated based on the readout arithmetic content. Main scanning and subscanning addresses are generated in accordance with the calculated second parameter and the detected first parameters. Whether or not the generated subscanning address is changed is detected. If it is detected that the subscanning address is changed, a subscanning address is generated using a subscanning step count upon a change in address as the second parameter. The input image is stored in the bit map memory in accordance with the generated main scanning and subscanning addresses. In order to generate addresses for a rotated figure free from gaps, the Bresenham's line generation algorithm is used in the main scanning direction, and subscanning addresses (start points of lines) are generated in accordance with an angle.
