用户将位图的透明背景色，设定在一个域值范围之内。

这个程序实现了256色PCX文件解码。注意：其中第二个函数对一行进行解码，应该把阅读的重点放在这个函数上。要注意的是，执行时，文件C: est.pcx必须存在，而且是一个256色PCX文件。-the procedures of 256 color PCX decoding. Note : This second function to decode and his party, should focus on reading this function on. To pay attention to the implementation, the C : test.pcx must exist, but is a 256-color PCX document.
