Receipt/Support – PDF Ninja Enterprise Plugin

Hi,

I did receive your contact form request. Looks like Microsoft banned my mail server IP. I tried delisting it using their instructions but looks like I am still getting bounces. Please send me an alternative email address I can use or send me your Skype/Signal/Slack/etc contact details.

Thank you.

Thanks for your reply.

Yeah I wasn’t sure if you would get the contact form or be able to reply so thought I would try here.

Ah OK cool. If you could please try [email protected]

Many thanks,

Nick

@nickmcg27 did you get the Enterprise Plugin working after? Was looking at it for a current project I’m working on.

Hi,

Can you please remind me what the problem was? The Enterprise Extension should be working, assuming the hosting requirements are met.

Thank you.

Hi @sherwin_flight

Sorry about the delay in reply. I was trying to find my notes from back then, couldn’t find them :S.

Ah my issue was using the AWS Linux 2 AMI – It doesn’t support one of the components of PDFtk named CGJ. I was looking through my web history and I think I just found these components from another location and just did a wget and install… or pointed to other repositories…

Here’s an AWS post on it https://forums.aws.amazon.com/thread.jspa?threadID=96919

And here’s a PDFLABS post on an install process https://www.pdflabs.com/docs/install-pdftk-on-redhat-or-centos/

Can’t remember now if I did that process exactly but I think I found CGJ from somewhere…

Either way if you’re starting from scratch don’t use an EC2 instance with Amazon Linux 2, they tend to depreciate things a lot quicker for security etc. a lot quicker than some of the other distro’s.

I don’t think the built-in PDF Extension utility checker works either. I met all the requirements and it’s still saying I don’t, but eh.

I wanted to use some additional functionality to sign a PDF for a second round, after it’s been through the Ninja PDF once. I just installed all the components of PDF Ninja extension manually to do this, because the binaries have been compiled into a single file in /var/www/html/wp-content/plugins/wpcf7-pdf-forms-enterprise/bin/x86_64/vm

And I found that hard to call and use.. not the best coder going around but eh, you install the full versions of the components and you can call them from the shell by their name. Links below.

PDFtk – as above.
QPDF – https://qpdf.sourceforge.net/
Poppler’s pdfinfo – https://poppler.freedesktop.org/releases.html
Poppler’s pdftocairo – https://poppler.freedesktop.org/releases.html
ImageMagick’s convert – https://imagemagick.org/script/download.php

Hi,

You can actually get the precompiled and ready to go PDFtk binary that is more up to date (than one from PDFLABS) from here: https://gitlab.com/pdftk-java/pdftk.

The vm binary is there just in case you don’t have those tools installed system-wide. A lot of shared hosting companies don’t install things on their servers for you. It is a single binary to minimize disk usage.

Let me know if you have a specific problem that you need help with.

Thanks.
