Hi, I'm currently using PDFBox to provide me with text/location information in order to heuristically detect table structures in a document. One way I'd like to enhance this is by making use of actual grid lines, when they are present. To do this, I believe I need to extract the vector graphics commands from the document.
I found one helpful post on this matter in the mail archives ( http://mail-archives.apache.org/mod_mbox/pdfbox-users/200902.mbox/browser). The recommendation was simply to override PageDrawer in order to intercept graphics commands. This sounds like a good idea, but I'm totally unsure of how to interpret the calls that I should be intercepting. Can anyone give me some advice here, or point me to a document that should make things clearer? Please be aware that I am both a newbie to PDFBox as well as the PDF document standard, so don't assume too much about what I already know. Thanks in advance. Ray Weidner
