摘要： A method of decoding image data in run representation, in which the data comprises a series of contiguous blades of various lengths, each block comprising pixels of the same colour, in order to present the image data in words of predetermined length; the method comprising the steps of: (a) identifying the colour and length of a first block within a first range corresponding to said predetermined length; (b) accessing a data table at an address corresponding to the said length and retrieving a word pattern from said predetermined address; and (c) processing said word pattern using an Exclusive-OR operator with a word of the said colour to produce a first output word.
If there are no further blocks of the same colour within the first range the processing of the first word is terminated; otherwise the first output word is combined with a further output word which is derived in accordance with the starting position and length of the said further block or blocks.摘要翻译： 一种在运行表示中解码图像数据的方法，其中数据包括不同长度的一系列连续的刀片，每个块包括相同颜色的像素，以便以预定长度的字呈现图像数据; 该方法包括以下步骤：（a）在对应于所述预定长度的第一范围内识别第一块的颜色和长度; （b）以对应于所述长度的地址访问数据表，并从所述预定地址检索字模式; 和（c）使用具有所述颜色的单词的异或运算符处理所述单词模式以产生第一输出单词。 如果在第一范围内没有相同颜色的其他块，则终止第一个字的处理; 否则第一输出字与根据所述另外的块或块的起始位置和长度导出的另一个输出字组合。
