The application discloses a method and an apparatus for rasterizing a page digital image. The method comprises steps of parsing a page digital image to obtain basic information, position information and rasterization information of the image, with the basic information including image data, image type, a width, height and bit depth of the image (S); decoding data encoding type to obtain the image data and saving the image data into a buffer (S); acquiring the image data from the buffer and rasterizing the image data by using the image type, the width, height and bit depth of the image and the position information to obtain a rasterized page lattice (S). The solution may reduce the reading and writing operations for data files on disk and improve the rasterization efficiency of the digital image.

Method and device for rasterizing page digital image

Disclosed is a method and system for automatically testing a raster image processor. The method may identify the correctness of the bitmap output by the raster image processor to be tested by comparing an abstract code of a bitmap generated by the RIP to be tested with that generated by a reference RIP to determine whether they are consistent with each other, so as to identify the correctness and stability of the RIP to be tested. Furthermore, the test samples can be submitted automatically. Thus, the convenience and efficiency are improved with respect to the manual submitting.
