本文给大家分享一段关于python实现屏幕截图及函数的代码，代码简单易懂，非常不错，具有参考借鉴价值，感兴趣的朋友一起看看吧

废话不多说，先给大家看下python实现屏幕截图的代码，具体代码如下所述：

									from selenium import webdriver

									import time

									def capture(url, save_fn="capture.png"):

									browser = webdriver.Firefox() # Get local session of firefox

									browser.set_window_size(1200, 900)

									browser.get(url) # Load page

									browser.execute_script("""

									(function () {

									var y = 0;

									var step = 100;

									window.scroll(0, 0);

									function f() {

									if (y < document.body.scrollHeight) {

									y += step;

									window.scroll(0, y);

									setTimeout(f, 50);

									} else {

									window.scroll(0, 0);

									document.title += "scroll-done";

									}

									}setTimeout(f, 1000);

									})();

									""")

									for i in xrange(30):

									if "scroll-done" in browser.title:

									break

									time.sleep(1)

									browser.save_screenshot(save_fn)

									browser.close()

									if __name__ == "__main__":

									capture(<a href="http://www.zzvips.com">https://www.zzvips.com</a>)

Pythony实现屏幕截屏的函数如下所述：

									# -*- coding: cp936 -*- 

									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 

									'''

									hwnd = 0

									hwndDC = win32gui.GetWindowDC(hwnd) 

									mfcDC=win32ui.CreateDCFromHandle(hwndDC) 

									saveDC=mfcDC.CreateCompatibleDC() 

									saveBitMap = win32ui.CreateBitmap() 

									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:\\')
