Joël Kuiper commented on PDFBOX-2337:
-------------------------------------
Here is a working implementation
https://gist.githubusercontent.com/joelkuiper/331a399961941989fec8/raw/9bc1a13eca6577c70c3a309214424cd6b0f2d3e6/TextHighlight
It may still require some refactoring but calling the file with <input-pdf>
<output-pdf> <pattern> will highlight the pattern in yellow
> Add an example for highlighting text based on a string

> An often heard request is to be able to highlight a certain text within a PDF
> programmatically, similar to the highlight functionality in Acrobat or
> Preview.app.
> The actual implementation of this functionality is trickier than it appears,
> since it requires the calculation of bouding boxes from TextPositions.
> A example class may help people with implementing this (common)
> functionality.
