function trouble upgrading from c to c++
I have a very small simple function using opencv libraries which takes a source image and stamps it to a location on a destination image. No matter what I try I am getting nowhere trying to update it to a c++ format. Here is the original.
void coriolus::stamp(IplImage * src, IplImage *dst, CvRect r)
{
IplImage * mask = cvCloneImage(src);
cvNot(mask,mask);
cvSetImageROI(dst, r);
cvCopy(src,dst,mask);
cvResetImageROI(dst);
cvReleaseImage(&mask);
}
I actually thought it would be something simple like
void stamp(Mat src, Mat dst, Rect r)
{
Mat mask = src.clone();
bitwise_not(mask,mask);
dst.adjustROI( Rect(r) );
src.copyTo(dst,mask);
}
what am I missing?
