I have written a program which enables me to draw on the webcam frame using a red colored object. Now for erasing my drawing, i have used the mousemove event or the left click event which enables me to erase the drawing and everything works fine. But when i have drawn a lot of stuffs on the webcam frame and use the mouse event to erase the drawing can be little hectic. So, i was wondering if there was a way i can actually delete the whole frame and get a fresh frame with no drawing in it. Is it possible? Thanks

You should keep details of all the drawings as you do them in a list of some type. You can then step through the list in reverse order removing each drawing element.

you must make a copy of the original frame at start of the process. If you also store allsteps you can implement an "UnDo" function which only repeats the first steps.
