Method and System for Rendering Rectangle Drawing Objects Using One-Line Raster Image Data

A method and system for rendering rectangle drawing objects are provided. 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. If the predetermined condition is satisfied, one-line raster image data associated with the second rectangle drawing object is generated and stored in a data buffer. 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.
