How to convert QImage to opencv Mat

Question

I have searched on the internet but I cannot find a method of converting a QImage(or QPixmap) to a OpenCV Mat. How would I do this?.

Answer 1

I'd save the image to disk and reopen it from cv ;)

@^ I've tried the previous solution. It doesn't seem to working with me. Although I'm getting some image, it looks like some bar code information kind of image. I guess there are some mismatch of parameters.
