If you want to open a "protected" pdf, the best way is to use the Ghostscript, it simple removes any protection of the pdf file. http://www.ghostscript.com/ -----Original Message----- From: Valdis.Kletnieksat_private [mailto:Valdis.Kletnieksat_private] Sent: sexta-feira, 17 de Maio de 2002 13:51 To: Dawes, Rogan (ZA - Johannesburg) Cc: 'Sumit Dhar'; Kurt Seifried; bad bob; vuln-dev Subject: Re: PDF modifications?

I would recommend that the xpdf developers not visit the US, lest they be Skylarov'ed. (The vuln-dev connection? Consider why Alan Cox censored a Linux kernel changelog - but further discussion should probably be moved to a political list. If you're in the US and of voting age, contact your Congresscreature and tell them you want them to support Rep. Rick Boucher (D-VA) in his attempts to fix the anti-circumvention clause of the DMCA).
