您好,以下是 Python 实现 Excel 区域截图的代码示例:
```python
import win32gui
import win32ui
import win32con
import win32api
import numpy as np
import cv2
# 获取 Excel 窗口句柄
hwnd = win32gui.FindWindow(None, "Excel")
# 获取 Excel 窗口左上角和右下角坐标
left, top, right, bottom = win32gui.GetWindowRect(hwnd)
# 计算区域截图的左上角和右下角坐标
x1, y1, x2, y2 = left + 100, top + 100, left + 500, top + 500
# 获取窗口 DC
hwndDC = win32gui.GetWindowDC(hwnd)
# 创建一个内存 DC
mfcDC = win32ui.CreateDCFromHandle(hwndDC)
saveDC = mfcDC.CreateCompatibleDC()
# 创建一个位图对象
saveBitMap = win32ui.CreateBitmap()
saveBitMap.CreateCompatibleBitmap(mfcDC, x2 - x1, y2 - y1)
# 将位图选入内存 DC
saveDC.SelectObject(saveBitMap)
# 复制区域到内存 DC
saveDC.BitBlt((0, 0), (x2 - x1, y2 - y1), mfcDC, (x1, y1), win32con.SRCCOPY)
# 将位图转换为 numpy 数组
bmpinfo = saveBitMap.GetInfo()
bmpstr = saveBitMap.GetBitmapBits(True)
img = np.fromstring(bmpstr, dtype='uint8')
img.shape = (bmpinfo['bmHeight'], bmpinfo['bmWidth'], 4)
# 将 BGRA 格式转换为 RGB 格式
img = cv2.cvtColor(img, cv2.COLOR_BGRA2RGB)
# 显示截图
cv2.imshow("Excel 区域截图", img)
cv2.waitKey(0)
# 释放资源
win32gui.DeleteObject(saveBitMap.GetHandle())
saveDC.DeleteDC()
mfcDC.DeleteDC()
win32gui.ReleaseDC(hwnd, hwndDC)
cv2.destroyAllWindows()
```
希望对您有所帮助!
