First and foremost you have to enhance PdfContentStreamProcessor to also process operators which create paths (foremost move-to, line-to, and rectangle) and then draw them. It's up to you whether you first collect all operations building a path and forward that path together with the drawing operator or forward each operation individually. Then you should either enhance the render listener interface or create a new interface to receive these drawing information. If the listener registered with the PdfContentStreamProcessor also implements that interface, you can forward the drawing instructions you collect in PdfContentStreamProcessor to it. Then your render listener implementation should implement that new interface, too, to receive the drawing information, collect them, and when all page information are processed, it shall compare the positions of the paths with the text and accordingly mark text as underlined.
