电脑已经安装wps，系统是Windows server2019
# 截图保存
def create_save_img(file_path, img_name):
# 读取excel内容转换为图片
import pythoncom
from win32com.client import DispatchEx
from PIL import ImageGrab
import os
file_path = os.path.abspath(file_path)
pythoncom.CoInitialize() # excel多线程相关
excel = DispatchEx("Excel.Application") # 启动excel
# del excel #这个地方很重要，杀死excel进程是这个地方起作用
# excel.Visible = False # 不显示Excel，而True可视化
excel.DisplayAlerts = True # 是否显示警告,关闭系统警告(保存时不会弹出窗口)
workbook = excel.workbooks.Open(file_path) # 打开excel
sheet = workbook.worksheets["Sheet1"] # 选择sheet
screen_area = sheet.UsedRange # 有内容的区域
screen_area.CopyPicture() # 复制图片区域
sheet.Paste() # 粘贴
'''
name = str(uuid.uuid4()) # 重命名唯一值
image_name = name[:6]
excel.Selection.ShapeRange.Name = image_name # 将刚刚选择的Shape重命名，避免与已有图片混淆
'''
excel.Selection.ShapeRange.Name = img_name # 将刚刚选择的Shape重命名，避免与已有图片混淆
sheet.Shapes(img_name).Copy() # 选择图片
img = ImageGrab.grabclipboard() # 获取剪贴板的图片数据
img.save(r"D:/static/media/img/" + img_name)
workbook.Close(False) # 关闭Excel文件，不保存
excel.Quit() # 退出excel
del excel # 这个地方很重要，杀死excel进程是这个地方起作用
pythoncom.CoUninitialize() # 关闭多线程
os.remove(file_path)
程序写了备注，报错在函数的
excel = DispatchEx("Excel.Application") # 启动excel
报错内容如下
