Yes; it does seem I started with the most difficult problem all while just picking up iText & the book. I had the .jar but I think its time for me to download the iText source.
Thank you for pointing me there. It does seem that's the best place to start and it seems I would need to rewrite/extend PRTokenizer or something similar. I am aware of some of what is involved. I wrote a program that found rects where words were probably hiding in a drag rectangle. It didnʻt do such a good job; Adobe Acrobat Pro does a much better job and itʻll figure out some text for me too. If I can only crack this puzzle with the detection I think I'll be fine.
