Patent ID: 7268912

Claim:
A rendering processing apparatus in which output information which is inputted is analyzed, a display list is formed, a bit map image is rendered into a band memory on the basis of said formed display list, and said rendered bit map image is outputted to a print mechanism, comprising: page processing means for sequentially dividing pages of the inputted output information on a band unit basis in a direction which is parallel with a raster scanning direction of said print mechanism; discriminating means for discriminating whether a raster scanning direction of the inputted output information and the raster scanning direction of said print mechanism are different or the same; forming means for forming a display list for rendering objects on the basis of the inputted output information; rendering means for rendering each of said objects to the bit map image into said band memory in accordance with said display list; rotating means for executing a rotating process on a band unit basis to the bit map images so as to be matched with the raster scanning direction of said print mechanism; and processing means for, if it is determined by said discriminating means that the raster scanning direction of the inputted output information and that of said print mechanism are different, allowing, after the bit map images are rendered by said rendering means, said rotating means to execute the rotating process to the rendered bit map images on a band unit basis and transferring the developed bit map images to said print mechanism.
