The layer displaying unit displays elements included in each of layers that form graphic data onto a display unit in a superposed manner. The graphic-element converting unit converts an element included in a first layer that forms the graphic data into a graphic element, and moves converted graphic element to a second layer that forms the graphic data. The element restoring unit restores a converted graphic element into a state before graphic element conversion.
