本文实例为大家分享了python基于win32实现窗口截图的具体代码，供大家参考，具体内容如下
获取窗口句柄和标题
import win32gui
hwnd_title = dict()
def _get_all_hwnd(hwnd, mouse):
if win32gui.IsWindow(hwnd) and win32gui.IsWindowEnabled(hwnd) and win32gui.IsWindowVisible(hwnd):
hwnd_title.update({hwnd: win32gui.GetWindowText(hwnd)})
win32gui.EnumWindows(_get_all_hwnd, 0)
for wnd in hwnd_title.items():
print(wnd)
运行结果如下，格式为：(窗口句柄, 窗口标题)
可自行根据标题筛选想要的窗口
(65772, '') (262798, 'pythonProject – screenShot.py') (5114244, '项目里程碑.ppt[兼容模式] - PowerPoint') (3803304, '') (133646, '') (133642, '')
根据窗口句柄截图
import win32com.client
import win32gui
import win32api
import win32con
import win32ui
from PIL import Image
def setForeground(hwnd):
"""
将窗口设置为最前面
:param hwnd: 窗口句柄 一个整数
"""
if hwnd != win32gui.GetForegroundWindow():
shell = win32com.client.Dispatch("WScript.Shell")
shell.SendKeys('%')
win32gui.SetForegroundWindow(hwnd)
def winShot(hwnd):
"""
根据窗口句柄截取窗口视图
:param hwnd: 窗口句柄 一个整数
"""
bmpFileName = 'screenshot.bmp'
jpgFileName = 'screenshot.jpg'
r = win32gui.GetWindowRect(hwnd)
hwin = win32gui.GetDesktopWindow()
# 图片最左边距离主屏左上角的水平距离
left = win32api.GetSystemMetrics(win32con.SM_XVIRTUALSCREEN)
# 图片最上边距离主屏左上角的垂直距离
top = win32api.GetSystemMetrics(win32con.SM_YVIRTUALSCREEN)
hwindc = win32gui.GetWindowDC(hwin)
srcdc = win32ui.CreateDCFromHandle(hwindc)
memdc = srcdc.CreateCompatibleDC()
bmp = win32ui.CreateBitmap()
bmp.CreateCompatibleBitmap(srcdc, r[2] - r[0], r[3] - r[1])
memdc.SelectObject(bmp)
memdc.BitBlt((-r[0], top - r[1]), (r[2], r[3] - top), srcdc, (left, top), win32con.SRCCOPY)
bmp.SaveBitmapFile(memdc, bmpFileName)
im = Image.open(bmpFileName)
im = im.convert('RGB')
im.save(jpgFileName)
if __name__ == '__main__':
setForeground(5114244)
winShot(5114244)
