	PCX RLE压缩图形的行对齐比.NET多了一位.已经修正了.

	2009 -7-25

	C# 转换图形为PCX 格式 增加了对1位色的PCX的读取

	

	2009-6 -12

	RLE数据压缩更改 颜色RGB在RLE压缩不换行处理.....

	

	.NET 支持的格式..保存成PCX格式..

	目前只支持两种结果 256色图 和24位图... 其他位的以后在说把..

	使用方法

	 Zgke.MyImage.ImageFile.ImagePcx _Pcx = new Zgke.MyImage.ImageFile.ImagePcx();
	 _Pcx.PcxImage = this.Icon.ToBitmap();
	 _Pcx.Save(@"C:/1.pcx");

	如果你看这篇文章...上篇

	http://blog.csdn.net/zgke/archive/2009/05/19/4201621.aspx C#解析PCX图形文件

	可以忽略了.下面的代码包含读和保存的功能..目前能保存256色图 和24位图..如果你的图形不是这两种 ..代码里把你的图形复制成24位的图 .然后去保存..

	

	全部代码.
