本文实例讲述了python使用PyGame绘制图像并保存为图片文件的方法。分享给大家供大家参考。具体实现方法如下：

''' pg_draw_circle_save101.py

draw a blue solid circle on a white background

save the drawing to an image file

for result see

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
