Method that does the same as Mat.convertTo with IplImage? OpenCV

Question

I'm applying contrast with opencv. I follow the docs to make contrast transformation with:

for(int y = 0; y < image.rows; y++) { 
  for(int x = 0; x < image.cols; x++) { 
    for(int c = 0; c < 3; c++) {
      new_image.at<Vec3b>(y,x)[c] =
         saturate_cast<uchar>(alpha*(image.at<Vec3b>(y,x)[c]) + beta);
    }
  }
}

But the contrast this method apply was not the one i want. So then i found this tutorial which uses:

Mat dst;
int iBrightness  = iSliderValue1 - 50;
double dContrast = iSliderValue2 / 50.0;
src.convertTo(dst, -1, dContrast, iBrightness);

but this uses Mat and for m work i'm doind IplImage. How could i made it with IplImage? I tried cvConvert but it seems to not do this.

do **not** use IplImages for anything. the c-api is deadbeef — berak, Dec 30 '15 at 15:50

i was using as my professor lead me saind IPlImages were faster than mat and my work would be real time — schirrel, Dec 30 '15 at 16:00

You can simply use

IplImage* img = new IplImage(srcImage);//where srcImage is cv::Mat.
