I saw a post about combining two pdf files into one.  
Somme people recommended to use the PDFtk Server.

I looked for the information but I can't use the PDFtk Server.

I'am trying to do it but I can't find the solution.

Somme one have an example script to gather several pdf pages into one? .

Why?

I use the command line tool from PDFtk Free. I don't have examples from within Ignition, but a typical command line would look like this:

```auto
pdftk A=SourceFile1.pdf B=SourceFile2.pdf cat A B output OutputFile.pdf

```

The `cat` verb accepts many variations to select page ranges, odd or even sets, and rotations.

~~It is not.~~ PDFtk is a legitimate command line tool whose open-source version is quite useful. It absolutely can be used with java's `ProcessBuilder` to manipulate PDF files on a gateway.

Edit: Ah, someone else already clipped the spam.

Install PDFtk into your gateway, outside Ignition.

Use java's `ProcessBuilder` to execute that tool in the background on the gateway, capturing the `stdout` carrying the output PDF bytes.

I don't see any example on the forum, sorry. It's not simple enough to just whip one up for you.
