Subject: Bug-feature in pdfTeX?
I am sending this mail to the three of you (Thanh, Sebastian, Hans),
because I actually did not understand who is taking care of the
documentation and who of the FAQs, while I perfectly know that Thanh is
taking care of the program (by the way I read your thesis on TUGboat;
excellent work; my congratulations!). And since I do not know if what I am
going to explain is a bug to be corrected, a feature to be documented or
just a frequent asked question to be answered I leave it up to you to decide.
I am perfectly happy with pdfLaTeX; when it will be able to deal with eps
material I'll be even happier, but the situation is perfectly allright even
with the actual situation.
The bug/feature I noticed takes place in connection with the pdf file
produced, but it shows up when Adobe Acrobat (version 4) is used on the pdf
file produced with pdfLaTeX.
With Adobe Acrobat it is possible to set two passwords, one for accessing
the document and another to set permissions and security features connected
to the document. While these passwords are settable and perform correctly
on a pdf file produced with Acrobat Distiller, they are not settable on a
pdf file produced with pdfLaTeX.
Is this a feature? Is it an unintended result and a small incompatibility?
Is it something Thanh could not implement because of classified information?
I do not know how many people are used to set security setting on their
documents, but this is one of the most interesting properties of the pdf
format, therefore if it was possible, I'd suggest to study the problem and
hopefully to solve it; meanwhile I'd update the documentations (I am
referring to the manual dated on the 21st of January 2000, which is the
version distributed with MiKTeX) so as to inform all pdf(La)TeX-users what
they can actually do and what is not permitted with pdf files produced with
While thanking you for your attention, I send you all my best regards
