Python实现截屏的函数详解编程语言

[Python]代码

import time,Image  
import os, win32gui, win32ui, win32con, win32api  
def window_capture(dpath):  
  '''''  
截屏函数,调用方法window_capture('d://') ,参数为指定保存的目录  
返回图片文件名,文件名格式:日期.jpg 如:2009328224853.jpg

  Image.open(bmpname).save(bmpname[:-4]+".jpg")  
  os.remove(bmpname)  
  jpgname=bmpname[:-4]+'.jpg'  
  djpgname=dpath+jpgname  
  copy_command = "move %s %s" % (jpgname, djpgname)  
  os.popen(copy_command)  
  return bmpname[:-4]+'.jpg'  
#调用截屏函数    
window_capture('d://')
