Python, Draw a circle with PIL

Question

I am looking for a command that will draw a circle on an existing image with PIL.

im = Image.open(path)

I want a function that will draw a colored circle with radius r and center (x,y)

Answer 1

image = Image.open("x.png")
draw = ImageDraw.Draw(image)
leftUpPoint = (x-r, y-r)
rightDownPoint = (x+r, y+r)
twoPointList = [leftUpPoint, rightDownPoint]
draw.ellipse(twoPointList, fill=(255,0,0,255))

refer official doc: PIL.ImageDraw.ImageDraw.ellipse(xy, fill=None, outline=None, width=0)
