# import library
from pgmagick import Image, DrawableCircle, DrawableText
from pgmagick import Geometry, Color
 
# Draw image of dimension 600 * 600 having background green
im = Image(Geometry(600, 600), Color("# 32CD32"))
 
# invoke DrawableCircle() function
circle = DrawableCircle(100, 100, 300, 20)
 
# invoke draw() function
im.draw(circle)
 
# set font size to 40px
im.fontPointsize(40)
