Win32gui Review

bmpinfo = bitmap.GetInfo() bmpstr = bitmap.GetBitmapBits(True) img = Image.frombuffer('RGB', (bmpinfo['bmWidth'], bmpinfo['bmHeight']), bmpstr, 'raw', 'BGRX', 0, 1) img.save('window_screenshot.png') pip install pywin32 After installation, you may need to run:

def automate_notepad(): hwnd = win32gui.FindWindow(None, "Untitled - Notepad") if not hwnd: print("Notepad not found") return win32gui

# Simulate Ctrl+S to save (requires keybd_event - not shown for brevity) # Or use SendMessage with WM_COMMAND to menu item bmpinfo = bitmap

1. Overview win32gui is a Python module that wraps a significant portion of the Microsoft Windows User Interface (UI) API, also known as the Win32 GUI API. It is part of the pywin32 (formerly win32all ) package, a set of Python extensions providing access to many Windows-specific functions, COM, and the Windows registry. hdc = win32gui

hdc = win32gui.GetWindowDC(hwnd) mfc_dc = win32ui.CreateDCFromHandle(hdc) save_dc = mfc_dc.CreateCompatibleDC() bitmap = win32ui.CreateBitmap() bitmap.CreateCompatibleBitmap(mfc_dc, width, height) save_dc.SelectObject(bitmap) save_dc.BitBlt((0, 0), (width, height), mfc_dc, (0, 0), win32con.SRCCOPY)
