PURPOSE:To freely and smoothly deform image data of a bit array system with less memory capacity. CONSTITUTION:Image data of a whole deformed object having the image A of an 'eye' shown in a diagram 'a' is previously divided into four in a length and into six in the width. Twenty four small rectangles (1)(2)(3)-(24) in total are generated. Then, the small rectangles (1)(2)(3)-(24) are respectively deformed into different quadrilaterals (1)' (2)' (3)'-(24)' shown in a drawing (b) in accordance with a prescribed deformation rule (a line sticking method, for example) as the whole deformed object is smoothly deformed. In such a process, image data of the bit array system, which is included in the small rectangles, are deformed with the deformation of the respective small rectangles. Namely, the array of dots is changed in accordance with the degree of deformation. Thus, it is not necessary to previously possess totally different whole image data as in a conventional case, and the image B of the deformed 'eye' is obtained with less memory capacity. |
