Is there some utility like in pdf tk to convert a pdf with arbitrary stuff in
it to some "Standard" or
canonical format that can let it be used with other tools so you don't have to
write custom code for
every little trivail variation of a thing you wish to accopmlish? For example,
cat xxx.pdf | pdf_to_standard_form | grep http
Obivously applicability would go beyond the immediate question but also let
people writing itext
code have some way to check their results more easily than "it opened in
proprietary adobe product X
but in black box Y it greyed out 3 menu options and wouldn't let me save it
unless blah blah bla ?"
There is nothing wrong with a human readable end product but given the
complexity of these things
it would be nice to use computers to automate certain things, like checking for
links
or other attributes. Without ability to use automated tools everything comes
down to a long
menu chain and terse messages from products not designed for debug.
