摘要： This invention relates to a method for attaching labels in page rasterizing, which in detail is the method how to add marks on the output medium when outputting the description files and belongs to computer picture process technique field. The page description files are PostScript file, i.e. PS file, and PortableDocumentFormat (PDF) files, i.e. PDF file. In the prior art, the method of attaching labels in outputting the page description files has a disadvantage of poor compatibility, slow speed and the like. By applying the present invention, it is realized to attach various labels to page description files when rasterizing inside of RIP, thereby it is possible to add marks to any of PS files and PDF files without pre-scanning the page description files, and obtain good flexibility and compatibility without effects on speed.

摘要： This invention relates to a method for preventing a copy of document, belonging to a technical field of entire copy protection of document. In the prior art, for some important documents, specially the secret ones, the reproduction of this kind of document is usually prohibited by its owner because of the security. But the technique in the prior art can not solve the problem of preventing unauthorized reproduction. The method of the present invention is intended to embed a shading pattern under the original image of an anti-copy document, detect the marker information hidden in the anti-copy document by an application program installed in the copy device, and decide whether the document can be copied legally or not. By the method of present invention, it is possible to detect the watermark information of the anti-copy document accurately and quickly, and prevent the reproduction of the anti-copy document thoroughly. Moreover, an additional memory space is no need.

摘要： The present invention discloses a frequency modulated screening method based on the dual feedback error diffusion. This method belongs to the method for generating halftone grid dots in the field of image hard copy. There is a certain technique difficulty in the prior FM and AM screening technology for the output device to output the good quality halftone image grid dots in low resolution, i.e. the satisfactory effect of the reproduction of the layered details in manuscript image as well as the image smoothess can not be achieved. The method of present invention organically combines the FM screening with the AM screening during the net hanging by using the dual feedback technique based on the basic arithmetic of error diffusion so that the effect of hybrid screening is achieved. In the case of the resolution of the output device is low, the method of present invention can solve the problem of easily losing of the layer of grid dots and can reduce the texture due to the random distribution characteristic, thus the richly layered halftone image of good quality can be output.
摘要翻译：本发明公开了一种基于双反馈误差扩散的频率调制筛选方法。该方法属于在图像硬拷贝领域中生成半色调网点的方法。在先前的FM和AM筛选技术中，输出设备在低分辨率下输出高质量的半色调图像网格点存在一定的技术难度，即，在原稿图像中的分层细节的再现以及图像的满意效果平滑无法实现。本发明的方法在净悬挂期间通过基于误差扩散的基本算术的双反馈技术将FM筛选与AM筛选有机地结合起来，从而实现了混合筛选的效果。在输出装置的分辨率较低的情况下，本发明的方法可以解决网格点层容易丢失的问题，并且由于随机分布特性可以减少纹理，因此，可以输出良好的质量。

摘要： Disclosed is a method for processing FM-AM mixed halftone images on a multi-bit depth imaging apparatus, which relates to a method for producing halftone dots in the field of image hard copying. In the prior art, since it is hard to avoid the impact of the error diffusion for the output apparatus to control the mixed dots with multi-bit imaging depth based on the error diffusion, the output of the mixed dots with multi-bit imaging depth cannot satisfy requirements of the apparatus. According to the method of the present invention, the dynamic algorithm for controlling the multi-bit mixed dots is used for screening based on the existing mixed screening process using dual-feedback error diffusion. Furthermore, multi-bit halftone images with high quality and rich gradations can be output by the multi-bit depth imaging apparatus. The method of the present invention can solve the phenomenon of sawtooth in the margins of the mixed dots output by the conventional single-bit apparatus and obtain the FM-AM mixed dots with the effect of high resolution and continuous gradations, which are output under low resolution.
摘要翻译：公开了一种用于在多位深度成像装置上处理FM-AM混合半色调图像的方法，其涉及用于在图像硬拷贝领域中产生网点的方法。在现有技术中，由于难以避免误差扩散对输出装置的影响，以基于误差扩散来控制具有多比特成像深度的混合点，所以具有多比特成像深度的混合点的输出不能满足设备的要求。根据本发明的方法，基于现有的使用双反馈误差扩散的混合筛选过程，使用用于控制多比特混合点的动态算法进行筛选。此外，多位深度成像设备可以输出具有高质量和丰富层次的多位半色调图像。本发明的方法可以解决传统单比特装置输出的混合点边缘锯齿现象，获得高分辨率和连续灰度效果的FM-AM混合点，输出功率低解析度。
