来自WinAPI的PIL和位图

Question

我有使用winapi制作窗口截图的代码.然后我必须将图像保存到磁盘并再次从磁盘加载到内存PIL.有没有任何方法可以立即保存到磁盘以在PIL中传递此位图.

import win32gui, win32ui, win32con
import Image

win_name='Book'
bmpfilenamename='1.bmp'
hWnd = win32gui.FindWindow(None, win_name)
windowcor = win32gui.GetWindowRect(hWnd)
w=windowcor[2]-windowcor[0]
h=windowcor[3]-windowcor[1]
wDC = win32gui.GetWindowDC(hWnd)
dcObj=win32ui.CreateDCFromHandle(wDC)
cDC=dcObj.CreateCompatibleDC()
dataBitMap = win32ui.CreateBitmap()
dataBitMap.CreateCompatibleBitmap(dcObj, w, h)
cDC.SelectObject(dataBitMap)
cDC.BitBlt((0,0),(w, h) , dcObj, (0,0), win32con.SRCCOPY)
dataBitMap.SaveBitmapFile(cDC, bmpfilenamename)

#dcObj.DeleteDC()
#cDC.DeleteDC()
#win32gui.ReleaseDC(hWnd, wDC)

im=Image.open(bmpfilenamename)
im.load()

Answer 1

注释掉这一行:

dataBitMap.SaveBitmapFile(cDC, bmpfilenamename)

并添加此项:

bmpinfo = dataBitMap.GetInfo()
bmpstr = dataBitMap.GetBitmapBits(True)
im = Image.frombuffer(
    'RGB',
    (bmpinfo['bmWidth'], bmpinfo['bmHeight']),
    bmpstr, 'raw', 'BGRX', 0, 1)
