Weblzw编码算法的步骤如下：步骤1：将词典初始化为包含所有可能的单字符，当前前缀p初始化为空。步骤2：当前字符c=字符流中的下一个字符。步骤3：判断p＋c是否在词典中（1）如果“是”，则用c扩展p，即让p=p＋c，返回到步骤2。 LZW compression uses a code table, with 4096 as a common choice for the number of table entries. Codes 0-255 in the code table are always assigned to represent single bytes from the input file. When encoding begins the code table contains only the first 256 entries, with the remainder of the table being blanks. See more The LZW algorithm is a very common compression technique. This algorithm is typically used in GIF and optionally in PDF and TIFF. Unix’s ‘compress’ command, among other uses.
