I have  project that will give me a zip file of like data that might be a combination of formats.   PDF, JPG, TIFF, BMP, ext.    This will be provided to a customer portal and zipped up via web service.

I then need to take that data and merge it into one PDF document that I can archive with Metadata.

The Metadata isn't a problem, I'll use the file name for that, but getting all the various inputs into one PDF file is posing the problem.

Thanks in advance.
