Hi Manuel, I'm sorry for my mistake and many thanks for your help and attention.
The best tool that I know to extract text from a PDF ( I didn't test Monarch), maintaining the correct layout, is inside a CAAT software: Caseware IDEA. However this software is very expensive and does a lot of other things. All the others tools that I tested (and I tested several) do wrong positioning analysis. It will be good to develop a tool to produce similar results obtained with IDEA. The work that you developed can help others to achieve that result.

In fact, Tabula does not support images. Thanks to PDFBox, it "mines" text and graphical elements, and uses a set of heuristics that attempt reconstruct a tabular structure. > Tabula also do incoherent analysis when a table is larger than one > page, for that reason Tabula is far from being a good tool for text > extraction with correct positioning. We always welcome bug reports (and patches!) :) [1] Thanks!
