Hi,

The difference is, you're subclassing PDFTextStripper to get the actual 
text position from the PDF. And this way you won't get any spaces 
because there are none in the PDF.

To illustrate this, I've uploaded page 3 treated with the 
DrawPrintImageLocations.java example from the source code download. See 
its source code for explanation on the colors.

The spaces from text extraction (that you get e.g. with 
"stripper.getText(doc);" ) are added by PDFBox but these have no 
TextPosition object.
