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 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
