Abstract

An adjustment is made to the size of an original graphic data object in a substantially rectangular original screen to obtain a target graphic data object on a substantially rectangular target screen having a different aspect ratio than that of the original screen. The size of the original graphic data object is proportionally increased to obtain the target graphic data object on the target screen. The size of the target graphic data object on the target screen is non-proportionally increased by the addition of a stretch distance thereto where a line projecting from a resizing point on and perpendicular to an edge of the original screen intersects the original graphic data object.
