Image formation from raster data selectively processed based on PDL fill or draw commands
First Claim
1. An image forming method for creating raster data based on image data written in a page description language, and forming an image based on the created raster data,wherein different image processing is implemented on first raster data created on the basis of a pattern fill command written in the page description language, and second raster data created on the basis of a command other than the pattern fill command, andupon the creation of the first raster data and the second raster data, different identification information is attached respectively to the first raster data and the second raster data, and the image processing is implemented on the basis of the identification information.

16. An image forming apparatus for creating raster data based on image data written in a page description language, and forming an image based on the created raster data, comprising:
-
an image processing switching unit which switches between image processing that is implemented on first raster data created on the basis of a pattern fill command written in the page description language, and image processing that is implemented on second raster data created on the basis of a command other than the pattern fill command; and an identification information attaching unit which attaches different identification information respectively to the first raster data and the second raster data upon the creation of the first raster data and the second raster data, wherein the image processing switching unit switches between the image processing that is implemented on the first raster data and the image processing that is implemented on the second raster data on the basis of the identification information attached by the identification information attaching unit. - View Dependent Claims (17, 18, 19, 20)
