How can I find all the x,y coordinates on the circumference of the circle; if I know the center of the circle and the radius of the circle. So in other words; imagine I have a circle in an image with its centre at 500,500. I know that the radius of this circle is 50 pixels. How can I find all the x,y coordinates that will be on the circumference of that circle. Further, the size of the image is 1280*720 pixels. Any suggestions or help is greatly appreciated.
