The invention provides a test method and device of a grid image processor. The method comprises steps of acquiring a test strategy parameter and a test sample set; using a target grid image processorand a reference grid image processor to correspondingly generate a target image and a reference image of each test sample in the test sample set; calculating a target blocking characteristic vector ofeach target image and a reference blocking characteristic vector of each reference image; comparing the target blocking characteristic vectors and the corresponding reference blocking characteristicvectors; if the target blocking characteristic vectors are different from the corresponding reference blocking characteristic vectors, comparing the target images and the reference images according tothe test strategy parameter; if the target images and the reference images fail to meet the test strategy parameter, calculating difference images of the target images and the reference images; and if the number of the difference images in the test sample set is larger than or equal to a preset threshold, determining that the target grid image processor fails to pass the test. According to the invention, automatic test of the grid image processor is achieved.
Description
technical field [0001] The embodiments of the present invention relate to the technical field of testing, and in particular to a testing method and device for a raster image processor. Background technique [0002] A raster image processor (English: Raster Image Processor, abbreviated as: RIP) is an interpreter, which is used to interpret and convert the layout information described in the page description language into data information that can be output by the output device. RIP is the core software component of the prepress processing system. The output quality, output speed and other performance indicators of a prepress processing system depend on the quality of RIP to a large extent. [0003] In order to ensure the quality of RIP, there are strict quality requirements in the RIP testing process. In the prior art, the testing of RIP products is carried out manually, and the process is as follows: testers submit test samples to the target RIP and benchmark RIP to be test...
