之前就一直想了解一下各种语言如何实现截屏/图像处理的功能,但一直没有找到合适的切入点,这次碰到了个Python的截屏功能(Windows系统)的代码,学习/修改了一下,用途还是比较多的(☆_☆)/~~
#!/usr/bin/env python # -*- coding: utf-8 -*- from PIL import Image import time, os, win32gui, win32ui, win32con, win32api def window_capture(dpath): ''' 截屏函数,调用方法window_capture('D:\photos2\'),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) # *.bmp is too big, so we convert it to jpg format 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:\photos2\') path = os.path.normcase("D:/photos2/") window_capture(path)
