Python实现截屏的函数

# -*- coding: cp936 -*-

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
'''
hwnd = 0

MoniterDev=win32api.EnumDisplayMonitors(None,None)
w = MoniterDev[0][2][2]
h = MoniterDev[0][2][3]
#print w,h#图片大小
saveBitMap.CreateCompatibleBitmap(mfcDC, w, h)
saveDC.SelectObject(saveBitMap)
saveDC.BitBlt((0,0),(w, h) , mfcDC, (0,0), win32con.SRCCOPY)
cc=time.gmtime()
bmpname=str(cc[0])+str(cc[1])+str(cc[2])+str(cc[3]+8)+str(cc[4])+str(cc[5])+'.bmp'
saveBitMap.SaveBitmapFile(saveDC, bmpname)
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:\\')
