Thank you for your answer. I had read about the possibilities of splitting pdfs and reading barcodes, but I want don't want to split pdfs by whole pages, I would like to be able to save a part of a page. For example split 1 (a4) page into two files; one from the top to 10 centimetre, the second one from 10 centimetres from the top to the bottom.
The height of the sections I want to save has to be determined by the location of the barcodes.
Something like this.
Is that possible?
