Abstract: A method for improving a speed of rasterizing transparent images, comprising determining, from P graphic entity objects on a transparent page, M transparent images and N nontransparent images. Each of the N nontransparent images includes an intersecting area with one of the M transparent images, P is an integer larger than 0, M is an integer larger than 0 and smaller than or equal to P, N is an integer larger than or equal to 0 and smaller than P, and P=M+N. The method also comprises determining a page-level transparent area and a page-level de-transparentizing area of the P graphic entity objects. Contributions of the transparent images and the nontransparent images to the page-level transparent area and the page-level de-transparentizing area are calculated using different methods. The methods further comprises assembling the M transparent images according to the page-level transparent area and the page-level de-transparentizing area.

Abstract: A method for rasterizing transparent pages scans each transparent page twice. The first scanning syntactically interprets a page description file of the transparent page, divides it into page blocks, and writes information of image element objects and transparency parameters into intermediate files. The second scanning reads the image element objects and the transparency parameters from the intermediate files and builds a page bitmap in blocks. A device for rasterizing transparent pages includes interpreting, dividing, file storing and building units. The interpreting unit implements syntactical interpretation. The dividing unit divides pages into transparent and nontransparent page blocks. The building unit implements rasterization according to the transparent or nontransparent page blocks, the information of image element objects and the transparent parameters to build a page bitmap in blocks.

Abstract: 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.
