Leonard -

My apologies for speaking from ignorance. I have found the PDF File Format document on Adobe's site, and it appears that all that is required to R/W PDF is a Copyright notice in your application. In that respect, it is slightly different from TIFF.

Although my point is still valid about other companies, it may not be true about Adobe.

Perhaps I was too quick to jump on Adobe due to their complete dismissal of all of my many attempts to ask for information on, or to be able to contribute to, some discussion of TIFF 7.0.

Let's clear something up here....

PDF is NOT proprietary! It is an fully published (and therefore public) specification. It is NO different than TIFF, where they published the specification, and maintain the rights to the name PDF, but allow 3rd parties to do what they want. So just as this group has extended the Adobe TIFF specification with a number of features, other folks have done the same with PDF (such as PDF/X-1 from DDAP).

The only big difference between the two is that someone (Sam) wrote a library for working with the files that everyone has supported and considers the "standard" implementation of TIFF. As such, there are LOTS of applications out there that support TIFF. However, in the PDF world, there are no "standard" libraries - there are a number of them (different languages (C, Pascal, Perl, etc.), different features (creation, parsing, etc.)) and there is only one standard "reader" (Acrobat), though Ghostscript and Xpdf do exist.
