It is an improvement on the LZ78 algorithm from Abraham Lempel and Jacob Ziv created by Terry Welch. It was patented by Unisys, the patent is now expired. This compression scheme works with a dictionary built while reading the stream.

The scenario described by Welch's 1984 paper encodes sequences of 8-bit data as fixed-length 12-bit codes. The codes from 0 to 255 represent 1-character sequences consisting of the corresponding 8-bit character, and the codes 256 through 4095 are created in a dictionary for sequences encountered in the data as it is encoded. At each stage in compression, input bytes are gathered into a sequence until the next character would make a sequence with no code yet … Web我不确定zlib或LZW压缩方法在单独压缩小于250字节的短字符串的情况下是否能正常工作。两者通常都需要创建一个相当大的字典，然后才能看到显著的压缩增益. 可能是使用固定的编码树进行简单的哈夫曼编码，或者是在字符串的所有实例之间共享编码树？

WebFor the moment, lets consider normal LZW encoding and decoding. GIF's variation on the concept is just an extension from there. LZW manipulates three objects in both compression and decompression: the charstream, the codestream, and the string table. In compression, the charstream is the input and the codestream is the output.
