When viewing a PDF both the kindle and the SONY do not edit the pdf. they just view it and save all highlights and annotations elsewhere. the output documents for both the kindle and the sony are useless as they are not spatially linked (or embedded) into the original document. I need a plug in that adds the notes, scribbles and/or higlights i make when viewing a PDF file on my ereader back into the original PDF file when using my prs-t1.
There is a way to do this using python scripts on both linux and windows as shown here:
but it is over my head. i think having Calibre do it would be cleaner.
