Hello, I commented on the gist. You have to use setSortByPosition(true) in the constructor right after super(). Be careful with your coordinate system. When you do textPosition1.getY() you get 792 not 0. I don't remember exactly where, but there is a class that uses the lower left corner of the page as the origin (0,0), not the upper left corner as it is natural.
I hope that helps. Alin PS Is the OCR going to be pure Java or will you be writing it in other language and use native calls?
