Methods And Devices For Processing A Raster Image

摘要

A raster image process method and device, for solving an issue existed in the current technique that it is unable to distinguish between the white color filled in a raster image when constructing the raster image and the white color in an image object of a page description filled in the raster image afterwards. The method includes: the raster image is constructed and the white color is filled in the raster image; a process of changing a color for the white color in an image object described in a page is carried out, and the image object is filled into the raster image. Thereby the white color filled in the raster image when constructing the raster image and the white color in an image object of a page description filled in the raster image afterwards can be distinguished.
