Hi,
I wish to draw a circle on an image (using GUI). What I want is to first click the centre point and when I will move the mouse the circle will grow or shrink. On the second click, it will stay on top of the image and I will get the x0, y0 and the radius, is it possible?
Thx.

Yes, you'll probably have to use ginput to get the center, then use the mousemove callback event to erase and draw circles as you move the mouse. You can use the rectangle function to draw circles. No, I don't have code for that all ready to hand you - I'd have to figure it out just as you do.
