[gnome-love] Gpdf PDF highlighting support

["W. Michael Petullo" <mike flyn org>]

Martin et al.,

I am interested in developing a GPL'ed application that supports taking
notes on a PDF file.  I would like to have the capability to do things
like highlight, bookmark, comment on or draw diagrams electronically on
top of an electronic document as if it was a paper document.  Rather than
starting from scratch, I thought I would see if you were interested in
adding these features to gpdf.

My concept is this:

1.  Gpdf opens a file.

2.  The user can use various tools to hightlight, bookmark, etc.
This information is automatically saved in some type of XML format
(in ~/gnome2/gpdf-something).  The filename of this overlay information
will be equal to the md5 hash of the original PDF document so that gpdf
knows what overlay to open for a given PDF.

3.  Of course, the user can also erase highlights, doodles etc.

I think this would be of great use to certain people.  Academics, lawyers
and other people that study documents would probably find it helpful.

What do you think?  Is adding this to gpdf feasible?  Or perhaps this
already exists?
