Good afternoon,
I am using PDFBox in a vb.net application. I’m looking to grab the
coordinates of certain words in a PDF. I’ve been trying to figure out
how to use TextPosition for this. Can you point me in the right direction?
Please try the PrintTextLocations.java from the example package from the
source code download:
