/                 Image Decompress Library                  /
/===========================================================/
/	This library do image decompress, call IDInit() before  /
/call any other functions, and call IDFree() when u finished/
/use this library. IDDecompress() will decompress an jpeg   /
/image to bitmap image.                                     /
