I've come up with a good way to insert color-filled rectangles through
the use of Overlay (so that they are rendered behind the text instead of
the front of it.)
However, how do I get the text coordinates? For example, I'd like to get
the coordinates for every occurrence of the word "mark me" so that I can
create a new PDDocument with filled rectangles and then overlay the
original over it. Currently, I have:
PDDocument document = PDDocument.load("src.pdf");
PDDocument underContent = new PDDocument();
PDPage underPage = new PDPage();
PDPageContentStream contStrm = new PDPageContentStream(underContent,
underPage);
contStrm.setNonStrokingColor(Color.yellow);
contStrm.fillRect(/* Here I need the coordinates */);
contStrm.close();
underContent.addPage(underPage);
Overlay overlay = new Overlay();
overlay.overlay(document, underContent);
underContent.save("out.pdf");
underContent.close();

If you would like to make the highlight part of the PDF you could
create an annotation or draw a rectangle behind the text.
Steps would be a. find the text b. get the coordinates of the text c.
create an annotation or a rectangle around the coordinates
You could also use the information in the highlight xml file to get
the coordinates for the annotation/rectangle

It is not apparent how to save a PDF after I highlight some text in
it. For example:
PDDocument doc = PDDocument.load("source.pdf"); PDFHighlighter hl =
new PDFHighlighter(); java.io.FileWriter xml = new
java.io.FileWriter("tmp.xml"); hl.generateXMLHighlight(doc, "450",
xml);
How do I now save source.pdf (or a copy of it, if overwriting is
not possible) with the text highlighted?
