Patent ID: 7184941

Claim:
A method for displaying a geometrical figure with a smoothed boundary line on the output unit of a terminal, the method comprising the steps of: designating, using an input unit of the terminal, a region of the geometrical figure for processing the boundary line; designating, using the input unit of the terminal, a smoothing factor representing a smoothing degree of the boundary line; applying a smoothing process to the boundary line of the geometrical figure using the smoothing factor to smooth the boundary line, wherein when the boundary is a concave region, applying a concave smoothing process to smooth the boundary; and when the boundary is a convex region, applying a convex smoothing process to smooth the boundary; and displaying the geometrical figure with the smooth boundary line on the output unit of the terminal wherein the concave smoothing process carries out the sweep operation for the boundary line of the geometrical figure, and applies the unsweep operation to a result of the sweep operation to smooth the boundary line and wherein the convex smoothing process carries out the unsweep operation for the boundary line of the geometrical figure, and applies the sweep operation to a result of the unsweep operation to smooth the boundary line.
