我们从Python开源项目中,提取了以下8个代码示例,用于说明如何使用win32con.SM_YVIRTUALSCREEN。
def grab_screen(region=None): hwin = win32gui.GetDesktopWindow() if region: left,top,x2,y2 = region width = x2 - left + 1 height = y2 - top + 1 else: width = win32api.GetSystemMetrics(win32con.SM_CXVIRTUALSCREEN) height = win32api.GetSystemMetrics(win32con.SM_CYVIRTUALSCREEN) left = win32api.GetSystemMetrics(win32con.SM_XVIRTUALSCREEN) top = win32api.GetSystemMetrics(win32con.SM_YVIRTUALSCREEN) hwindc = win32gui.GetWindowDC(hwin) srcdc = win32ui.CreateDCFromHandle(hwindc) memdc = srcdc.CreateCompatibleDC() bmp = win32ui.CreateBitmap() bmp.CreateCompatibleBitmap(srcdc, width, height) memdc.SelectObject(bmp) memdc.BitBlt((0, 0), (width, height), srcdc, (left, top), win32con.SRCCOPY) signedIntsArray = bmp.GetBitmapBits(True) img = np.fromstring(signedIntsArray, dtype='uint8') img.shape = (height,width,4) srcdc.DeleteDC() memdc.DeleteDC() win32gui.ReleaseDC(hwin, hwindc) win32gui.DeleteObject(bmp.GetHandle()) return cv2.cvtColor(img, cv2.COLOR_BGRA2RGB)
def grab_screen(region=None, title=None): hwin = win32gui.GetDesktopWindow() if region: left,top,x2,y2 = region width = x2 - left + 1 height = y2 - top + 1 elif title: gtawin = win32gui.FindWindow(None, title) if not gtawin: raise Exception('window title not found') #get the bounding box of the window left, top, x2, y2 = win32gui.GetWindowRect(gtawin) width = x2 - left +1 height = y2 - top +1 else: width = win32api.GetSystemMetrics(win32con.SM_CXVIRTUALSCREEN) height = win32api.GetSystemMetrics(win32con.SM_CYVIRTUALSCREEN) left = win32api.GetSystemMetrics(win32con.SM_XVIRTUALSCREEN) top = win32api.GetSystemMetrics(win32con.SM_YVIRTUALSCREEN) hwindc = win32gui.GetWindowDC(hwin) srcdc = win32ui.CreateDCFromHandle(hwindc) memdc = srcdc.CreateCompatibleDC() bmp = win32ui.CreateBitmap() bmp.CreateCompatibleBitmap(srcdc, width, height) memdc.SelectObject(bmp) memdc.BitBlt((0, 0), (width, height), srcdc, (left, top), win32con.SRCCOPY) signedIntsArray = bmp.GetBitmapBits(True) img = np.fromstring(signedIntsArray, dtype='uint8') img.shape = (height,width,4) srcdc.DeleteDC() memdc.DeleteDC() win32gui.ReleaseDC(hwin, hwindc) win32gui.DeleteObject(bmp.GetHandle()) return cv2.cvtColor(img, cv2.COLOR_BGRA2RGB)
