So many people ask about manipulating, editing and generally processing PDF
files. In my experience, PDF is a write-once format - any manipulation should
have been done in whatever source generated the PDF. I think of a
PDF as being a
piece of paper: if you want to change the content of a piece of paper it is
usually best to chuck it away and start again...
That's a good way to put it.
All the attempts I have done into opening up a PDF file and then
trying to make sense of it and put it back together with something
changed have been absolute failures.
The algorithm used to make a PDF file reminds me of a
replacement-type compression technique -- it's not easy to understand
what was done.
Cheers,
