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

In the new OpenCV 2.0 C++ interface it's not really necessary to change from back and forth between Mat and IplImage, but if you want to you can use the IplImage operator:

IplImage dst_img = dst;

Note that only the IplImage header is created and the data (pixels) will be shared. For more info see the OpenCV C++ interface or the image.cpp example in the OpenCV-2.0/samples/c directory.
