To view a PDF document without comments displayed on the page, you can hide all comments at once, rather than closing or deleting each comment manually. The same control lets you show all comments.

Optical Character Recognition, or OCR, is a software process which enables images of printed text to be translated into machine-readable text. OCR is most commonly used when scanning paper documents to create electronic copies, but can also be performed on existing electronic documents (e.g. PDF).

This object holds information about the current user who is logged onto the machine using Nitro Pro. You can view this information in Preferences as well.

You use Nitro Pro to export form data as a separate FDF file (form data format). An exported FDF file is much smaller than the original PDF form file, making it much more convenient for distributing to others. You can email an FDF file to another user who can then import the data into a PDF file, or you can use FDF files to save form data locally, as well as to import data into your forms.

To provide a complete description of how you can use JavaScript with Nitro Pro is well beyond the scope of this user manual. If you wish to gain programming knowledge in JavaScript, we recommend you review sources you can find on the Internet, as well as in books on JavaScript that can be obtained from your local library or book seller.

This object allows you to get and set the properties of a PDF link, as well as set a Run a JavaScript action.

The Microsoft Office add-ins give you additional control over the PDF files you produce, including options for adding security, inserting bookmarks and hyperlinks, customizing pages sizes, compressing images, and much more. The settings vary based on the Office program you are using, and you can set different settings for each program, depending on the types of files you wish to produce.

When you click a PDF file in your web browser, the Nitro Web Browser Plugin reads the file and displays it in the web browser.

The I.R.I.S. OCR plugin fully integrates with Nitro Pro allowing it to recognize text from scanned pages, or from images in open PDF documents. The OCR utility is fully customizable, with options to configure options such as skewed image correction, to image compression settings. You can also enable text recognition for scanners directly on the Create PDF From Scanner dialog, to automatically create PDF documents from scanned pages with text that can be modified or searched.
