Component to view and annotate PDF documents [closed]

Answer 1

If anyone's interested, it looks like we'll end up using jPDFNotes, from Qoppa Software.

To quote from the web site:

jPDFNotes is a Java™ bean that integrates into your application to display PDF documents and forms and allow your users to annotate the documents and fill the forms. After editing documents, the library can save them to a local file or the host application can override the save function to save the file to any location locally or on a network.

jPDFNotes is built on top of Qoppa's proprietary PDF technology so your users do not have to install Acrobat Reader or any other third party software or drivers. jPDFNotes is 100% Java so it is completely platform independent and so can run on Windows, Linux, Unix, Mac OSX and any other platform that supports the Java runtime environment.

It's not what we started looking for, but it seems to be exactly what we need. They seem a nice bunch of people too.

Answer 2

For editing the documents I have worked with SyncFusions Essential PDF and it worked quite well

Answer 3

There's also http://a.nnotate.com which you can use as a PDF / Word annotation component in web applications - just uses AJAX / JS / HTML and displays the pdfs properly in the browser without needing adobe reader. (see http://a.nnotate.com/embed-guide.html for a working demo)

Answer 4

The free version Foxit Reader does this, you can do Tools->Commenting Tools->Note, then click anywhere on the page of the PDF to place a little note icon which has text inside. Then just save the PDF. Later, if someone views the PDF in Acrobat or Foxit, just hover the mouse over or click on the little note icons on the page to view the comments.
