    • Modifying a color lookup table includes receiving a first image, a first color lookup table (CLUT) indexed in a first image color space, and a second CLUT indexed in a colorimetric space. Tracer pixels from the second CLUT are generated and retained, each tracer pixel including color coordinates of a corresponding unique node in the first CLUT. Tracer pixels are inserted into the first image, and tracer pixels are tracked. Color adjustments are made using image editing software to generate an adjusted combined image having adjusted tracer pixels. The adjusted tracer pixels are extracted. The second CLUT is converted to a third CLUT having a size N1×N2×N3×N4 by replacing each of the output-device color coordinates of the second CLUT nodes by modified device color coordinates computed from the adjusted color coordinates of the adjusted tracer pixels.
    • 修改颜色查找表包括接收第一图像,在第一图像颜色空间中索引的第一颜色查找表(CLUT)和在比色空间中索引的第二CLUT。 生成并保留来自第二CLUT的跟踪器像素,每个示踪器像素包括第一CLUT中对应的唯一节点的颜色坐标。 跟踪器像素被插入到第一图像中,跟踪像素被跟踪。 使用图像编辑软件进行颜色调整,以产生具有调整的跟踪像素的经调整的组合图像。 提取调整后的跟踪像素。 第二CLUT被转换成具有大小为N1×N2×N3×N4的第三CLUT,通过从经调整的跟踪像素的调整色坐标计算出的修改的设备颜色坐标替换第二CLUT节点的每个输出设备颜色坐标 。

    • A method of processing a digital document (100) which comprises content and a pattern of position identification markings comprises providing at least one electronic record of a digital document from which a second document can be produced containing substantially the same content as the digital document. The electronic record, which is preferably stored on a server (304) connected to a network, also includes information relating to the pattern printed in the digital document. The method further includes the steps of receiving a document request, the request including pattern information retrieved from the digital document (100) using a pattern reading device (300), accessing the electronic record which includes pattern information that corresponds to the retrieved pattern information and transmitting the electronic record in response to the receipt of the document request. The transmitted information may be used to generate a copy of the printed digital document (100) which includes any markings made on the document (100) with a digital pen (300).
    • 一种处理数字文档(100)的方法,其包括内容和位置识别标记的图案包括提供数字文档的至少一个电子记录,从该数字文档的第二个文档可以被制造出包含基本上与数字文档相同的内容。 优选地存储在连接到网络的服务器(304)上的电子记录还包括与打印在数字文档中的图案有关的信息。 该方法还包括以下步骤:接收文档请求,所述请求包括使用模式读取装置(300)从数字文档(100)检索的模式信息,访问包括对应于检索到的模式信息的模式信息的电子记录,以及 响应于接收到文档请求而发送电子记录。 所发送的信息可以用于生成印刷数字文档(100)的副本,其中包括用数字笔(300)在文档(100)上作出的任何标记。
