I purchased a set of instrucional CD's which contain some
files in pdf format.
Unfortunately when I try to convert them with pdf2txt, I get a message stating tthat the text
cannot be copied.
Once upon a time I vaguely recall hearing that there is a single bit in the pdf file
that sets the copy protected mode.
Can anyone tell me if this is so and what the offset and bitmask would be?
