import pygame as pg

# create the display window
win = pg.display.set_mode((width, height))
# optional title bar caption
pg.display.set_caption("Pygame draw circle and save")
# default background is black, so make it white
win.fill(white)
# draw a blue circle
# center coordinates (x, y)
radius = min(center)
# width of 0 (default) fills the circle
# otherwise it is thickness of outline
width = 0
# draw.circle(color, pos, radius, width)
pg.draw.circle(win, blue, center, radius, width)
# now save the drawing
# can save as .bmp .tga .png or .jpg
fname = "circle_blue.png"
pg.image.save(win, fname)
print("file {} has been saved".format(fname))
# update the display window to show the drawing pg.display.flip()
# event loop and exit conditions
# (press escape key or click window title bar x to exit) while True:
for event in ():
pe == pg.QUIT:
# most reliable exit on x click
pg.quit()
raise SystemExit
pe == pg.KEYDOWN:
# optional exit with escape key
if event.key == pg.K_ESCAPE:
pg.quit()
raise SystemExit
