Setup a field to display the date X days from today

A user just requested a new feature over on our Customer Connect site, to be able to display ‘future dates’ in text fields.
I would like to be able to format a field for x number of days from todays date.
Lucky for them, this is already possible via some custom JavaScript code, using the Date object.

Setting default colors & styles for comments

If you find yourself changing the color of the PDF markup annotations in Nitro Pro repetitively, then please read on. There *is* a way for you to set the default properties for a particular type of markup annotation (this also works for form fields too BTW).
1. Create your comment/markup.
2. Right click, go to Properties and [...]

AIIM study on PDF usage in organizations

An AIIM study into the usage of PDF in organizations has found that 90% of organizations are already using PDF to store and archive their documents, as reported by GCN.
The introduction of PDF/A (a subset of the PDF spec, designed for long term document archiving – http://en.wikipedia.org/wiki/PDF/A) would be one of the main contributors to [...]

Question from a customer: “Will Nitro Pro accept that PDF file?”

I was just scouring our sales inquires at the end of the day (something I like to do, see what questions and issues pre-sales are being asked) and noticed a question that is pretty straightforward for us PDF nerds, but I’m sure a others would think about it when considering a non-Adobe PDF solution.
Will Nitro [...]

Differences between Save and Save As

The majority of our users probably aren’t aware there are some big differences between performing a Save and Save As in PDF editing applications such as Nitro PDF Professional and Adobe Acrobat. Over the years I’ve found myself referring to Save as being a ‘quick save’ and a Save As as a ‘full save’.
To talk [...]

Participate in developing the Nitro Pro roadmap

When it comes to identifying features to assign to a particular release of Nitro PDF Professional, a major influence is what our customers are requesting (it’s pretty obvious hey). To date we’ve been keeping track of this via our customer support system, but it hasn’t been the most efficient way of going about it. We [...]

Say Hello to the Form Tools Context Ribbon

As mentioned in earlier posts, the 5.4 release of Nitro PDF Professional was very forms centric. We made some major improvements to form support, and one of these is the Forms Tools context ribbon.
This ribbon appears when you have a form field selected. To see what I’m talking about, add a form field to a [...]

An introduction to forms in Nitro Pro 5.4

If you’ve read Richard’s post regarding the release of Nitro PDF Professional 5.4, then you’re probably already aware of the update to Nitro Pro’s forms functionality. Calling it an ‘update’ though, doesn’t really do it justice. We have totally rebuilt forms from scratch and it is much different and improved compared with previous versions. If you’re [...]

Nitro Pro 5.3.3 released

Nitro PDF Professional 5.3.3 was released on our website this week. It includes a number of important bug fixes, and an update to the Tools panel.
We’ve broken out some of the features (Edit, Snapshot) on the Tools panel that were previously hidden away within a drop-down menu, to make them more accessible to users. This [...]
