I am trying to display an image and what I want to do is to record in the variable h if the user clicks within an area of the image (h=1 if the users clicks within that area and h=0 if not) and save in the variable n the number of left-mouse clicks that the user makes within that area.
The image is immage.png and the three points that determine the "area" commented above are: pointA, pointB and pointC

How can I achieve that? I have been searching but I didn`t find anything
Thank you very much
