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/2.0, source.rows/2.0); Mat rot_mat = getRotationMatrix2D(src_center, 40.0, 1.0); Mat dst; warpAffine(source, dst, rot_mat, source.size()); ``` Once I have my `dst` `Mat` variable type filled up I would like to put it back to an `IplImage` variable type, any idea about how to do this?

Accepted Answer

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.
