Markup a PDF with drawing tools
The drawing tools in Nitro Pro allow you to add predefined shapes (for example, lines, rectangles, or ovals) as well as free-form drawings to your PDF documents. These drawing tools include a corresponding pop-up note, enabling you to provide additional comments or further explanation for each drawing. You can also change the appearance of your drawings, with options for color, opacity, pointer styles, and more, depending on the type of drawing you use.

JavaScript
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.

Initial View Properties
PDF documents can be set to display in particular ways when opened in a PDF viewer. For example, if your document contains bookmarks and you want them to be easily accessible, you can set the document to open with the Bookmarks pane already displayed. You can also set your PDF so it’s displayed at a particular zoom level, opens at a particular page, and so on. In Nitro Pro these settings are all controlled in the Document Properties dialog.

Import and Export Form Data
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.
