PROBLEM TO BE SOLVED: To provide an image processor, an image-forming device and an image processing method, which shorten the rotational processing time of rectangular data and which can reduce the load of CPU. SOLUTION: A 90 degrees rotational processing is explained. In a memory (a) storing rectangular data of CG(character generator) ROM and the like, 16 bits are read downward from an upper left data in the memory (b) of buffer RAM for printing (b) are written downward from the upper right. In the memory (a), sixteen bits are continuously read and they are written downward into a place left to a place where they are written. The operation is continued until a processing longitude terminates. In the memory (a), a system moves to the head of next right, 16 bits are read downward and they are written into a place below the place into which data are written at first in the memory (b). Such operation is continued until processing lateral width terminates and the rotational processing terminates. |
