摘要： 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.

摘要： The application provides a method for rasterization. According to the method, a primitive may be divided, at a position where a color abruptly changes in the primitive, into a plurality of sub-primitives with continuously and gradually changing colors. Each of the sub-primitives is then rasterized. The present application further provides an apparatus for rasterizing an image. The apparatus may comprise a dividing module configured to divide a primitive at a position where a color abruptly changes into a plurality of sub-primitives with continuously gradually changing colors. Furthermore, the apparatus may comprise a rasterizing module configure to rasterize each of the sub-primitives. The application may improve the speed of the rasterization and the quality of the processed image.

摘要： The invention relates to a technical field of graphic image processing, especially to a technology for simplifying a complex path. The invention provides a method and a device for simplifying a complex path, to accomplish simplification of any complex path into a simple path of a region described by the complex path. The method for simplifying a complex path comprises: parsing the complex path into a vector linked-list consisted of linked monotonic vectors; dividing each vector in the vector linked-list into vector segments according to intersection points of the vector with other vectors in the vector linked-list; and extracting from all vector segments the vector segments located on a boundary of a region defined by the complex path, and connecting the extracted vector segments according to their location to obtain a simple path. According the method of the present application, a complex path can be simplified to a simplest path defining a region by utilizing node scanning process, such that operations on a vector level for a complex path can be realized.
