我是OpenCV的新手，目前正在使用Windows窗体应用程序(Visual c++ 2008)显示图像。教程指导我独立制作头文件(称为cvToBitmap.h)，然后将其应用于项目中头文件的stdafx.h。头文件的功能是将IplImage格式的图像转换为位图格式。但是，当我编译程序时，在头程序中出现了50个程序错误。
下面是cvToBitmap.h源程序
#ifndef _CVTOBITMAP_H_
#define _CVTOBITMAP_H_
static void FillBitmapInfo (BITMAPINFO* bmi, int
width, int height, int bpp, int origin)
{
assert ((bmi&&width>=0)&&(height>=0)&&((bpp==8)
||(bpp==24)||(bpp==32)));
BITMAPINFOHEADER* bmih=&(bmi->bmiHeader);
memset(bmih,0,sizeof(*bmih));
bmih->biSize=sizeof(BITMAPINFOHEADER);
bmih->biWidth=width;
bmih->biHeight=origin?abs(height):-abs(height);
bmih->biPlanes=1;
bmih->biBitCount=(unsigned short)bpp;
bmih->biCompression=BI_RGB;
if(bpp==8){
RGBQUAD* palatte = bmi->bmiColors;
for(int i=0;i<256;i++){
palette[i].rgbBlue=palette[i].rgbGreen=palette[i].rgbRed=(BYTE)i;
palette[i].rgbReserved=0;
}
}
}

您应该包含BITMAPINFO结构的头文件-将#include <windows.h>添加到您的头文件
