Python精灵模块的capture截图指令

from sprites import Screen,Sprite

screen = Screen()
screen.setup(480,360)
screen.bgpic('res/sky.png')

bug = Sprite()
bug.pensize(10)
bug.pendown()

for x in range(360):
    bug.randomcolor()
    bug.fd(1)
    bug.rt(1)

# 别名是：capture,截取当前窗口内容保存为图
screen.save('abc.png')
im = screen.save()  #  不写文件名，则返回PIL图形对象
print(im)
screen.mainloop()
