Hello,
I have a question concerning the drawContours function.
I've searched on the internet and on the openCV forum but without any success.
What I'm looking for is when I have a square contour, fill the inside of this contour using a specific color.
So far when I draw the contour, the border is red and the inside is filled with white :
cv::drawContours(targetMat, contours, maxAreaIdx, cv::Scalar(255,0,0),CV_FILLED);
What can I do for filling the inside with a specific color (if possible using RGBA)?
I've tried using cvRectangle function but I don't know how to convert a cv::Mat to CVArr (I'm not sure this function will help btw).
I really thank you for your help
