Qimage与IplImage的转换

QImage test2012::ImageCV2Qimg(IplImage* img)
{
assert(img!=NULL);
int h = img->height;
int w = img->width;
int channel = img->nChannels;
QImage qimg = QImage(w, h, QImage::Format_RGB32);

for(int i=0;i<h;i++)
    {
        for(int j=0;j<w;j++)
        {
            int r,g,b;
            if(channel == 3)
            {
                b=(int)CV_IMAGE_ELEM(img,uchar,i,j*3+0);
                g=(int)CV_IMAGE_ELEM(img,uchar,i,j*3+1);
                r=(int)CV_IMAGE_ELEM(img,uchar,i,j*3+2);
            }
            else if(channel == 1)
            {
                b=(int)CV_IMAGE_ELEM(img,uchar,i,j);
                g=b;
                r=b;
            }
            qimg.setPixel(j,i,qRgb(r,g,b));
        }
    }
return qimg;
}

Qimage的存储顺序是RGB，而IplImage的存储顺序是BGR，所以我们要按顺序恢复。
