Python实现屏幕截图的两种方式 - weiyinfu - 博客园 https://www.cnblogs.com/weidiao/p/8051280.html

def window_capture(filename):
    hwnd = 0  # 窗口的编号，0号表示当前活跃窗口
    # 根据窗口句柄获取窗口的设备上下文DC（Divice Context）
    hwndDC = win32gui.GetWindowDC(hwnd)
    # 根据窗口的DC获取mfcDC
    mfcDC = win32ui.CreateDCFromHandle(hwndDC)
    # mfcDC创建可兼容的DC
    saveDC = mfcDC.CreateCompatibleDC()
    # 创建bigmap准备保存图片
    saveBitMap = win32ui.CreateBitmap()
    # 获取监控器信息
    MoniterDev = win32api.EnumDisplayMonitors(None, None)
    w = MoniterDev[0][2][2]
    h = MoniterDev[0][2][3]
    # print w,h　　　#图片大小
    # 为bitmap开辟空间
    saveBitMap.CreateCompatibleBitmap(mfcDC, w, h)
    # 高度saveDC，将截图保存到saveBitmap中
    saveDC.SelectObject(saveBitMap)
    # 截取从左上角（0，0）长宽为（w，h）的图片
    saveDC.BitBlt((0, 0), (w, h), mfcDC, (0, 0), win32con.SRCCOPY)
    saveBitMap.SaveBitmapFile(saveDC, filename)

BOOL BitBlt(
  _In_ HDC   hdcDest,
  _In_ int   nXDest,
  _In_ int   nYDest,
  _In_ int   nWidth,
  _In_ int   nHeight,
  _In_ HDC   hdcSrc,
  _In_ int   nXSrc,
  _In_ int   nYSrc,
  _In_ DWORD dwRop
);

Parameters

hdcDest [in]

A handle to the destination device context.

nXDest [in]

The x-coordinate, in logical units, of the upper-left corner of the destination rectangle.

nYDest [in]

The y-coordinate, in logical units, of the upper-left corner of the destination rectangle.

nWidth [in]

The width, in logical units, of the source and destination rectangles.

nHeight [in]

The height, in logical units, of the source and the destination rectangles.

hdcSrc [in]

A handle to the source device context.

nXSrc [in]

The x-coordinate, in logical units, of the upper-left corner of the source rectangle.

nYSrc [in]

The y-coordinate, in logical units, of the upper-left corner of the source rectangle.

dwRop [in]

A raster-operation code. These codes define how the color data for the source rectangle is to be combined with the color data for the destination rectangle to achieve the final color.
