Pygame 保存图片

先写个程序画椭圆动图：

import math
import pygame
pygame.init()

windowSize = [400, 300]
screen = pygame.display.set_mode(windowSize)
clock = pygame.time.Clock()

width = 200 
height = 200
x = windowSize[0] / 2 - width / 2
y = windowSize[1] / 2 - height / 2
color = pygame.color.Color('#57B0F6')
black = pygame.color.Color('#000000')

count = 0
done = False
fileNo = 0

while not done:
    screen.fill(black)
    pygame.draw.ellipse(screen, color, [x, y, width, height])
    width += math.cos(count) * 10
    x -= (math.cos(count)*10)/2
    height += math.sin(count)*10
    y -= (math.sin(count)*10)/2
    count += 0.5

    pygame.display.flip()

    if fileNo < 5:
        pygame.image.save(screen, "circle" + str(fileNo) + ".png") #这句话保存图片
        fileNo += 1

    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            done = True
    clock.tick(24)
pygame.quit()
