Q:

 
We are looking at using your SDK for an android app that will be used by schools to distribute PDF  notes, homework etc. We would like to provide annotation (keyboard + pen) features. From the features list I think that this is possible but I would like to confirm and find out if the annotations are saved back to the PDF or a separate XML file. Reason for asking is that we would like to backup all annotations without necessarily backing up the entire PDF over wifi/3G

A:
 

PDFNet has extensive annotation support, and annotations can be saved back to the PDF or be exported as a separate FDF or XFDF file. XFDF (XML Forms Data Format) is a format for representing forms data and annotations in a PDF document. It is the XML version of Forms Data Format (FDF), a simplified version of PDF for representing forms data and annotations.

You can get started by requesting a trial here: http://www.pdftron.com/pdfnet/mobile/request_trial.html. You may also want to check out the following snippets: FDF (http://www.pdftron.com/pdfnet/samplecode.html#FDF), Annotation:  http://www.pdftron.com/pdfnet/samplecode.html#Annotation etc.
