How to convert a Mat variable type in an IplImage variable type in OpenCV 2.0?

Question

I am trying to rotate an image in OpenCV.

I\'ve used this code that I found here on Stack Overflow:

Mat source(img);
Point2f src_center(source.cols/2         


        

Answer 1

For having the whole IplImage object, I've used this code:

Mat matImage;
IplImage* iplImage;

iplImage = cvCreateImage(cvSize(640,480), IPL_DEPTH_8U, 1);
iplImage->imageData = (char *) matImage.data;

You can also copy the data instead of pointer:

memcpy(iplImage->imageData, matimage.data, 640*480);
