"I found out the following tool but not able to use it correctly", could you be a bit more precise please? Did you read the manual? What is the error message? What is the input coming from? Could you post an example? What is wrong with the output if any? Honestly, I find it a bit absurd that I still have to ask an experienced user for such clarification again and again. Also, this is not really a bioinformatics question.

closing for 3 reasons: off-topic or not relevant to bioinformatics (rather a support request to pdfposter) and insufficient details given, therefore unable to provide an answer (hint: check documentation at http://pythonhosted.org/pdftools.pdfposter/), and no longer relevant after 8 months of inactivity.
