念住向GalPhotoAuto加处理*.gal的功能，不过最后因为Gale.spi静系可以返回24位的图片，坑之。
下边代码可以系Visual Studio 2012直接编译。

二，BMP数据合成
例如，spi_pic 取得的 bmpdata 只是数据部分，bmpinfo 是再前一D的信息，仲差最开头的14位数据。
完整的BMP是：开头的14位数据 + bmpinfo + bmpdata
开头的14位数据：
42 4D E6 E5 00 00 00 00 00 00 36 00 00 00
其中
E6 E5 00 00 = B0 E5 00 00 + 36
原bmpinfo：
28 00 00 00 8C 00 00 00 8C 00 00 00 01 00 18 00 00 00 00 00 B0 E5 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
修改为：
28 00 00 00 8C 00 00 00 8C 00 00 00 01 00 18 00 00 00 00 00 B0 E5 00 00 12 0B 00 00 12 0B 00 00 00 00 00 00 00 00 00 00
