PURPOSE:To deform the two-dimensional bit map image so that a path is put thereto artificially by combining the processing for executing variable power of picture element density in accordance with a shape of a deformed image with respect to a two-dimen sional bit map original image, and the processing for deforming the shape of the original image to the shape of the deformed image designated arbitrarily. CONSTITUTION:Variable power of picture element density in one direction of a bit map original image being a rectangular square shape is executed so as to be propot- tional to the ratio of a pair of opposite side lengths (Q1Q2 and Q3Q4) of a bit map image of a quadrangle to be deformed, and also, variable power of picture element density in the remaining one direction of the original image is executed so as to be proportional to the ratio of the remaining pair of opposite side lengths (Q1Q4 and Q2Q3) of the image to be deformed, by which the processing for giving a depth sense is executed. Simultaneously, by a pseudo affine deformation processing, the deformation processing extending from the rectangular quadrangle of the original image to a deformed arbitrary square shape is executed. In such a way, the two-dimensional bit map image can be deformed so that a path is put thereto. |
