unotools insert image into document (libreoffice)

Question

I'm trying to insert an image into a libreoffice document that is handled/controlled by unotools.

Therefore I start LibreOffice with this command:

soffice --accept='socket,host=localhost,port=8100;urp;StarOffice.Service'

Inside my python code I can connect to LibreOffice:

from unotools import Socket, connect
from unotools.component.writer import Writer
context = connect(Socket('localhost', 8100))
writer = Writer(context)

(This code is taken from this documentation: https://pypi.org/project/unotools/)

By using writer.set_string_to_end() I can add some text to the document. But I also want to insert an image into the document. So far I couldn't find any resource where this was done. The image is inside of my clipboard, so ideally I want to insert the image directly from there. Alternatively I can save the image temporarily and insert the saved file.

Is there any known way how to insert images by using unotools? Any alternative solution would also be great.

I've found a way to insert images by using uno instead of unotools:

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

def connect_to_office():
    if not 'XSCRIPTCONTEXT' in globals():
        localContext = uno.getComponentContext()
        resolver = localContext.ServiceManager.createInstanceWithContext(
                         'com.sun.star.bridge.UnoUrlResolver', localContext )
        client = resolver.resolve("uno:socket,host=localhost,port=8100;urp;StarOffice.ComponentContext" )
        global XSCRIPTCONTEXT
        XSCRIPTCONTEXT = ScriptContext(client, None, None)

def insert_image(doc):
    size = Size()
    path = uno.systemPathToFileUrl('/somepath/image.png')
    draw_page = self.doc.DrawPage
    image = doc.createInstance( 'com.sun.star.drawing.GraphicObjectShape')
    image.GraphicURL = path
    draw_page.add(image)
    size.Width = 7500
    size.Height = 5000
    image.setSize(size)
    image.setPropertyValue('AnchorType', 'AT_FRAME')

connect_to_office()
doc = XSCRIPTCONTEXT.getDocument()
insert_image(doc)

I still don't know how to insert an image from my clipboard, I worked around that problem by saving the image first. If someone knows a way to insert the image directly from the clipboard that would still be helpful.
