Get the height of Windows Taskbar using Python

To get the work area size (desktop minus taskbar):

from win32api import GetMonitorInfo, MonitorFromPoint

monitor_info = GetMonitorInfo(MonitorFromPoint((0,0)))
work_area = monitor_info.get("Work")
print("The work area size is {}x{}.".format(work_area[2], work_area[3]))

To get the taskbar height:

from win32api import GetMonitorInfo, MonitorFromPoint

monitor_info = GetMonitorInfo(MonitorFromPoint((0,0)))
monitor_area = monitor_info.get("Monitor")
work_area = monitor_info.get("Work")
print("The taskbar height is {}.".format(monitor_area[3]-work_area[3]))

Take Screenshot on Windows Using Python

from PIL import ImageGrab
im = ImageGrab.grab()
im.save('screenshot.png')

Or

import win32gui, win32ui, win32con, win32api
hwin = win32gui.GetDesktopWindow()
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)
bmp.SaveBitmapFile(memdc, 'screenshot.bmp')

Don’t forget to SetProcessDPIAware if necessary

import ctypes

user32 = ctypes.windll.user32
user32.SetProcessDPIAware()
