When using the following syntax is for cv::Mat
cv::putText(...)
What about putting text into an IplImage? Is there a way to do so, without making changes / converting from Mat to IplImages?
Did you mean "...without making changes / converting from IplImages to Mat" ?
What about cvPutText(CvArr* img, const char* text, CvPoint org, const CvFont* font, CvScalar color) ?
