VC++ 调用 Susie 插件

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。

一，源码

#include "stdafx.h"
#include <windows.h>

	long left, top;	// 起点坐标
	long width;			// 宽度
	long height;		// 高度
	WORD x_density;	// 水平方向密度
	WORD y_density;	// 垂直方向密度
	short colorDepth;	// 色深
	HLOCAL hInfo;		// 图像中的文本信息
} PictureInfo;

//---------------------------------------------------------------------------

	return 0;
}

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
