["Joël Kuiper (JIRA)" <ji...@apache.org>]

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

> 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.
