''' pg_draw_circle_save101.py
draw a blue solid circle on a white background
save the drawing to an image file
for result see http://prntscr.com/156wxi
tested with Python 2.7 and PyGame 1.9.2 by vegaseat 16may2013
'''
import pygame as pg
# pygame uses (r, g, b) color tuples
white = ( 255 , 255 , 255 )
blue = ( 0 , 0 , 255 )
width = 300
height = 300
# 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)
center = (width / / 2 , height / / 2 )
radius = min (center)
# width of 0 (default) fills the circle
# otherwise it is thickness of outline
width = 0
# draw.circle(Surface, 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 pg.event.get():
if event. type = = pg.QUIT:
# most reliable exit on x click
pg.quit()
raise SystemExit
elif event. type = = pg.KEYDOWN:
# optional exit with escape key
if event.key = = pg.K_ESCAPE:
pg.quit()
raise SystemExit
