Question

How do we convert IplImage to a QPixmap or QImage?

If the only answer is save the Iplimage then load it to the QPixmap, then how do we do that?

Answer 1

IplImage * ImageToIplImage(QPixmap * qPix){

    int width = (qPix->toImage()).width();
    int height =(qPix->toImage()).height();

    // Creates a iplImage with 3 channels

    IplImage *img = cvCreateImage(cvSize(width, height), IPL_DEPTH_8U, 3);

    for(int y=0;y<height;y++)
    {
        for(int x=0;x<width;x++ )
        {
            QRgb color = qPix->toImage().pixel(x,y);
            cvSet2D(img,y,x,cvScalar(qBlue(color),qGreen(color),qRed(color),1));
        }
    }
    return img; }

it worked !! thanks to Fateh benmerzoug
