[] Jepg2000的压缩解压-Jepg2000

Description:

WAVELET.DSW －是JPEG2000 API函数体的VC工作区
本代码通过VC6.0正常编译，并有详细的注解方便读者开发和阅读。
BIT.H BIT.C －是有关比特位操作的代码
MCHANNEL.H MCHANNEL.C －是关于信道设置、传输的代码
WAVELET.H WAVELET.C －是小波操作的代码
MAIN.C －是API函数集成的主函数

上述代码均是有详尽的注释，读者可逐一进行阅读。
其中，重点部分是：WAVELET.H和WAVELET.C，关于信道方面的问题，书中给出了定义
和处理的方法，请阅读相关章节。

该代码没有经过编译。需要注意的事项：
代码编译后生成的是一个.dll文件而非一个可执行文件，必须通过调用才能实现功能，
另外生成的.dll文件会自动拷贝到"wavelet_gui"目录中。如果在编译成功后出现一个
关于指定可执行文件路径的提示，可以忽略它，也可以指向名为JPEG2000的可执行文件
所在地路径。笔者建议大家忽略这个关于文件路径的提示。
