寻找一个实现LZW COM pression / DECOM pression库 [英] Looking for library which implements LZW compression/decompression

问题描述

我需要学习如何使用笔和纸做的的Lempel-谢夫 - 韦尔奇 COM pression我算法和数据结构类。不幸的是，我们只有几个例子在我们它是如何做的书。我想用它来练习COM pressing和DECOM pressing的文字，但我需要找到一个方法来检查，如果我是正确的做对还是错。其中一个选项是做一个计划，将COM preSS / DECOM preSS字符串，并显示文本。我知道这不会是太困难从零做一个计划，这将是很好的学习经验，但我宁愿避免在实现算法的决策失误。

I need to learn how to do Lempel–Ziv–Welch compression using pen and paper for my algorithms and data structures class. Unfortunately we have only a couple of examples in our book of how it is done. I'd like to practice compressing and decompressing text using it, but I need to find a way to check if I'm right doing it right or wrong. One of the options is make a program which will compress/decompress a string and show text. I know that it wouldn't be too difficult to make a program from zero and that it would be good learning experience, but I'd rather avoid making mistakes in implementation of algorithm.

所以我在寻找一些preferably自由/开源库，CAN通讯preSS和DECOM preSS LZW为C / C ++ / C＃/ Java的。

So I'm looking for some preferably free/open source library which can compress and decompress LZW for C/C++/C#/Java.

推荐答案

的libtiff 提供的 LZW的COM pression套件和马克·纳尔逊的 LZW数据通信pression 教程包括一些工作源。

LibTIFF provides a LZW Compression Kit, and Mark Nelson's LZW Data Compression tutorial includes some working source.
