PURPOSE:To provide an image deforming method which is capable of freely and smoothly deforming image of a bit array form with a little memory capacity, and a device for the method. CONSTITUTION:When the vertexes of plural small polygons forming the same line (p line) inside a deforming object are moved according to the parameter of a Bezier curve, the vertexes of small other polygons are moved so that the whole of the deforming object may be smoothly deformed and the vetexes of the other small moved polygons are calculated based on the vertex after the small polygon of the p line is moved. At this time, as the parameters of a curve, the both ends cordinates of the curve (xb1, yb1) and (xb4, yb4) and cordinates of (xb2, yb2) and (xb3, yb3) controlling the bending way of the curve are used. The shape of each small polygon after a deformation corresponding to each calculated vertex is determined, an original image is deformed so as to correspond to the data of the small polygon after the deformation and the whole of the image is prepared. |
