PURPOSE:To obtain the graphic data processor which can perform graphic deformation processing such as expansion processing or contraction processing without any complicate processing for vector graphic data constituting a figure represented in contour description. CONSTITUTION:This graphic data processor in provided with an expansion processing part which calculates the expanding direction of the figure, represented in contour description, at each coordinate point of the vector graphic data constituting the figure, a contour description data alteration processing part which adds the expanding direction information at the coordinate points to the vector graphic data to alter the vector graphic data on the figure represented in contour description, and a figure contour updation processing part which calculates coordinate point data after the coordinate point data are moved in the expanding direction from the altered vector graphic data according to a given expansion quantity and updates the vector graphic data represented in contour description. |
