C# 解析 RSB图形结构

      文件结构非常简单 ，就是 16位图   R使用 5位  G使用6位  B使用5位
           //显示RSB文件
            ImageRsb _RSB = new ImageRsb(@"D:/temp/4.rsb");
            pictureBox1.Image = _RSB.Image;

            //保存
            ImageRsb _RSB = new ImageRsb();
            _RSB.Image = (Bitmap)Image.FromFile(@"d:/TEMP/1.bmp");
            _RSB.SaveImage(@"d:/temp/ok.rsb");

     这个文件不知道ACDSEE为什么标记为24位图形 实际只有16位。 如果谁有这个格式的文档请发到[e-mail]谢谢拉
