For at least a first rectangle drawing object and a second rectangle drawing object, a determination is made if the second rectangle drawing object satisfies a predetermined condition with respect to the first rectangle drawing object.

The one-line raster image data indicates a filling color of the second rectangle drawing object over a first extent in a first direction. Subsequently, the one-line raster image data may be used a number of times over a second extent in a second direction perpendicular to the first direction to fill a drawing region corresponding to at least the second rectangle drawing object.
