If the PDF is locked with a password, but still printable, the approach offered
by this author is one that would work, while attempting to use this approach on
the original PDF would fail. This author was simply trying to help the poster
with an approach that would avoid the frustration that would ensue if he tried
to work with an original locked PDF.
Of course, the approach espoused by the esteemed sage would be easier, for both
unlocked and unlocked PDFs. OTOH, this author doesn't count easier to fail as
an acceptable approach.
Cheers,
Bill Segraves
