I've found something interesting here: http://www.pdflib.com/fileadmin/pdflib/pdf/manuals/TET-4.1-manual.pdf
"Area of text extraction. By default, TET will extract all text from the visible page area. Using the clippingarea option of open_page( ) (see Table 10.10, page 172) you can change this to any of the PDF page box entries (e.g. TrimBox). With the keyword unlimited all text regardless of any page boxes can be extracted. The default value cropbox instructs TET to extract text within the area which is visible in Acrobat." How can I have the same behavior using Tika?
