David KELLER commented on PDFBOX-1767:
--------------------------------------

For example I use Lucene / SolR to index and find text in document, then I use 
TextLocationHighlight  to render a image with the highlighted text found.

I try to use Pdfbox to add transparent image but it fails for now, and works 
perfectly with iText :-(

> Its a work of several years (since 2009) on Pdfbox to be able to find text 
> and replace it by text/image/clearText, and I want to drop it to the apache 
> community.
> To do it, I needed to update 3 classes in your project : 
> PDPageContentStream.java, PDFStreamEngine.java and PDFTextStripper.java
