[Deepak Keswani]

I have installed pdfsandwich on Ubuntu and I'm trying to execute below command for .tif (Multipages tif file) to .pdf file and it throws below error message.

Can you please help me on this?

Currently, pdfsandwich only accepts pdf files as input files. Could you convert your tiff to pdf (there should be command line utilities for this) and try it with the resulting pdf as input to pdfsandwich?
