Re: What is the best pdf editor for ubuntu?

[Luis Paulo]

Well, what I really meant was 
"if you want to edit a pdf, use adobe acrobat"

But I didn't want to say it. That was the free, no cost cost issue :)


And when I wonder about PDF not being open, neither the software, I should have said I think the software that produces adobe pdf format is not open. It's the software that is open or not (true?). My mistake.

Still, about the PDF format, the adobe format, that is:

"On January 29, 2007, Adobe announced its intent to release the full
Portable Document Format (PDF) 1.7 specification to AIIM, the
Enterprise Content Management Association, for the purpose of
publication by the International Organization for Standardization
(ISO). During 2007 and into early 2008 that intent was turned into a
reality. ISO published the approved ISO 32000-1 standard based upon PDF
1.7 in July 2008. ISO will also produce future versions of the PDF
Specification.

Since ISO 32000 is equivalent to Adobe's PDF 1.7, Adobe is not
producing a PDF 1.8 Reference. However, Adobe is publishing a document
specifying what extended features for PDF, beyond ISO 32000-1 (PDF
1.7), are supported in its newly released products. This makes use of
the extensibility features of PDF as documented in ISO 32000 in Annex E."
from http://www.adobe.com/devnet/pdf/pdf_reference.html. 

Got it? I may be wrong, but I think
the idea is that the standard is made after the implementation. And adobe can write the ISO, but even so, the ISO is based on, not the adobe implementation. Ya.


Other example that I may know more of: html/dom w3c standards and microsoft. 

microsoft html/dom is not standard. They have functions/tags that are not in the standards, it's not just a matter of interpretation, or lacking of features.

Are they open, the microsoft versions? Not the question, probably. microsoft software is not open. Are they standard? No. No matter how many documentation microsoft
produces about it. 

microsoft don't care about standards unless they have to. Adobe is different, they bought a standard. Too much?


The point was that today you can't have a successful linux pdf editor of adobe documents unless, maybe, adobe makes it.
You may have a pdf cracker, pdfedit may be one of those. Sometimes it breaks. 

Because adobe didn't release the source of adobe acrobat, and I'll bet that the format it
produces is not standard. Not the latest version, not the previous, not the next. It will always have a lot of non standard and undocumented tweaks. 
Again, may be wrong all the way, I don't know, its just an educated guess.

arshad: could you tell with what software did you create the pdf in question, from the source you don't have at the moment? That was my other point. Maybe it' s not an adobe pdf, that is.

Really appreciate your comments. 
Just don't know what is "schrieb", but I'm guessing it's something like escreveu. Kidding.

PS: Long message. Sorry, but I'll send it anyway.
PS: ISO is not for free :)
