libreoffice python:如何设置图像的文本环绕属性

import uno
from com.sun.star.awt import Size

def set_image_wrap_properties(image_url, wrap_type):
    # 连接到LibreOffice进程
    local_context = uno.getComponentContext()
    resolver = local_context.ServiceManager.createInstanceWithContext(
        "com.sun.star.bridge.UnoUrlResolver", local_context)
    ctx = resolver.resolve("uno:socket,host=localhost,port=2002;urp;StarOffice.ComponentContext")
    smgr = ctx.ServiceManager

    # 获取当前文档
    desktop = smgr.createInstanceWithContext("com.sun.star.frame.Desktop", ctx)
    document = desktop.getCurrentComponent()

    # 获取文档的图形集合
    draw_pages = document.getDrawPages()
    draw_page = draw_pages.getByIndex(0)
    draw_shapes = draw_page.getShapes()

    # 加载图像
    image = draw_page.createInstance("com.sun.star.drawing.GraphicObjectShape")
    image.GraphicURL = image_url
    image.setSize(Size(10000, 10000))  # 设置图像大小

    # 设置文本环绕属性
    wrap = image.getPropertyValue("TextWrap")
    wrap.Type = wrap_type
    image.setPropertyValue("TextWrap", wrap)

    # 将图像添加到文档
    draw_shapes.add(image)

    # 保存文档
    document.storeToURL("file:///path/to/save/document.odt", ())

    # 关闭LibreOffice进程
    document.close(True)

# 设置图像的文本环绕属性为四周环绕
