Creating trustedfunction for addWatermarkFromFile

I'm brand new to Adobe programming and I'm trying to automate the conversion of an Excel worksheet into a PDF. I need to add a footer and, through Google research, found out how to do it using "addWatermarkFromText". Now I need to add an image to the header so I guess I'll have to use "addWatermarkFromFile". I found out though that that function needs a "trustedfunction" wrapper and I don't know how to create one. Apparently, you create the trustedfunction and save it to a particular folder.

Does anyone know how to do this? Thanks very much for any help.

Look at the Acrobat Javascript reference:

Yes, I have a document called "Acrobat JavaScript Scripting Reference" that seems to be similar, if not identical, to the "JavaScript for Acrobat API Reference".

I'm afraid I still don't know how to compose the TrustedFunction wrapper.
