错误头文件将IplImage转换为位图

时间：2013-06-02 17:49:02

标签： c++ opencv bitmap iplimage

我是OpenCV的新手，目前正在使用Windows Form App（Visual C ++ 2008）显示图像。本教程指示我在将它应用于项目头文件的stdafx.h之前独立创建一个头文件（称为cvToBitmap.h）。头文件用于将IplImage格式的图像转换为位图格式。但是，当我编译程序时，它在头程序中发生了50个程序错误。

以下是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;
        }
    }
}

System::Drawing::Bitmap^ IplImageToBitmap(IplImage* src){
    SIZE size = (0,0);
    int channels=0;
    void* dst_ptr=0;
    const int channels0=3;
    int origin=0;
    CvMat stub,dst,*image;
    bool changed_size=false;

    HDC hdc=CreateCompatibleDC(0);
    if(CV_IS_IMAGE_HDR(src))
        origin=src->origin;
    image=cvGetMat(src,&stub);
    uchar buffer(sizeof(BITMAPINFO*)buffer;
    size.cx=src->width;
    size.cy=src->height;
    channels=channels0;
    FillBitmapInfo(binfo,size.cx,size.cy,channels*8,1);
    HBITMAP hBitmap=reateDIBSection(hdc, binfo,DIB_RGB_COLORS, &dst_ptr,0,0);
    if (hBitmap==NULL)
        return nullptr;
    cvInitMatHeader(&dst, size.cy,size.cx,CV_8UC3, dst_ptr, (size.cx*channels+3)&-4);
    cvConvertImage(image, &ddst, origin=0 ? CV_CVTIMG:0);
    System::Drawing::Bitmap^ bmpImage=
        System::Drawing::Image::FromHbitmap(
        System::IntPtr(hBitmap));
    DeleteObject(hBitmap);
    DeleteDC(hdc);
    return bmpImage;
}
#endif

我不知道，缺少的部分是什么..请帮助..谢谢..

答案 0 :(得分：0)

您应该在BITMAPINFO结构中添加标题 - 在标题文件中添加#include <windows.h>。
