Extract text from PDF to bookmarks

Question

I need to extract text from PDF right where the bookmark is.

PDFBox retrieves the entire page where the bookmark is located, as described here .

But I need to extract the text starting with the bookmark.

Answer 1

I believe iText can handle this.

Rectangle2D bookmarkRect = getRectFromBookmark(someBookmarkThingy);

FilteredTextRenderListener filter = 
  new FilteredTextRenderListener( new LocationTextExtractionStrategy(), 
                                  new RegionTextRenderFilter( bookmarkRect ));

String bookmarkText = PdfTextExtractor.getTextFromPage(reader, pageNum, filter);

someBookmarkThingythere will probably be the PdfDictionary of the bookmark in question.

WARNING Bookmarks can actually contain almost any action. Usually they contain one of several variations of the GoTo * action.
