PDFBox PDAnnotation Multiple Quads

[Jonny O <jo...@gmail.com>]

Hello.

I am using PDFBox to both extract annotations from, and add annotations to
a PDF file. I originally used JavaScript within Acrobat to do this, but it
is much too slow and very restricted. So it is very nice to use PDFbox.

However, all subclasses of PDAnnotation only seem to allow the user to get
or set one quad. The problem however is that Acrobat can create multiple
quads for the one annotation (as it appears to me). For example, if a user
creates a single highlight across two or more lines, several individual
boxes (quads) will be seen, however, they act as one when editing or
deleting.

JavaScript in Acrobat accepts a 2D Array when getting or setting quads. Is
it possible to replicate this using PDFBox? Perhaps this functionality was
left out due to the complexity of the PDF structure?

I have exhausted my time and knowledge on this one, and I hope some advice
might help me get some energy back :)

Thank you for your time.
Jonny O.

The array of floats returned by
getQuadPoints<http://pdfbox.apache.org/apidocs/org/apache/pdfbox/pdmodel/interactive/annotation/PDAnnotationTextMarkup.html>()
will return all of the quads associated with the annotation, in a single
array.
Each group of 8 floats represents one quad.
