Python, Draw a circle with PIL

问题:

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)

回答1:

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

回答2:

Use ImageDraw.ellipse with square bbox like (0,0,10,10), which mean with diameter 10.

回答3:

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

using this way i am unable to make it translucent, it is always opaque
