Python PIL | ImageDraw.Draw.arc()

  • Last Updated : 02 Aug, 2019
Geek Week

PIL is the Python Imaging Library which provides the python interpreter with image editing capabilities. The ImageDraw module provide simple 2D graphics for Image objects. You can use this module to create new images, annotate or retouch existing images, and to generate graphics on the fly for web use.

ImageDraw.Draw.arc() draws an arc (a portion of a circle outline) between the start and end angles, inside the given bounding box.

Syntax: PIL.ImageDraw.Draw.ellipse(xy, fill=None, outline=None)

Parameters:

xy – Four points to define the bounding box. Sequence of [(x0, y0), (x1, y1)] or [x0, y0, x1, y1].
start – Starting angle, in degrees. Angles are measured from 3 o’clock, increasing clockwise.
end – Ending angle, in degrees.
fill – Color to use for the arc.



Returns: An Image object in arc shape.




   
  
# importing image object from PIL
import math
from PIL import Image, ImageDraw
  
w, h = 220, 190
shape = [(40, 40), (w - 10, h - 10)]
  
# creating new Image object
img = Image.new("RGB", (w, h))
  
# create rectangle image
img1 = ImageDraw.Draw(img)  
img1.arc(shape, start = 20, end = 130, fill ="pink")
img.show()

Output:

Another Example: Here we use different colour for filling.
