Hi Todd, this "ever-tightening set of PDF rules" was not ever tightening anything. It is called the PDF specification, and what you call 'tightening' is just the proper implementation of the specificaiton's 'contract'. Please do everyone a favor and write spec-compliant files. IMO Adobe's lenient interpretation of file validity in Acrobat was a weakness and should have never been done. It opens up room for incompatible file variations. If you want PDF to be the winner, and to have lasting value, you want to make it easy for a 3d party software to understand your PDFs. The only real way to do that is to write compliant files. If this was enforced by Acrobat in the first place the developers would have seen the problems very quickly and fixed them. Instead we have these 'production' systems spitting out files whose Portable Document Format status it truly questionable. sorry for the tone, I just have seen enough problematic files to piss me off. ======================================== Max Khesin, software developer - [EMAIL PROTECTED] [check out our image compression software at www.cvisiontech.com, JBIG2-PDF compression @ www.cvisiontech.com/cvistapdf.html] ----- Original Message ----- From: "Todd Kueny" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Wednesday, June 04, 2003 5:46 PM Subject: Re: [PDFdev] validator > > PDFdev is a service provided by PDFzone.com | http://www.pdfzone.com > _____________________________________________________________ > > > > Acrobat 4.0 was and is still a useful validation tool and many of our > production customers still use it - its the only one that still runs on > all the other Acrobat platforms (Solaris, HP/UX, etc.).
