Hi Luigi,

pdf spec. www.adobe.com/devnet/acrobat/pdfs/PDF32000_2008.pdf xpdf sources

That sounds like a definite reference ... probably more than I can digest for a start :-( Perhaps there's a simple, example-driven guide for dummies somewhere? Like writing a simple PDF document with more than one page, non- contiguous text blocks and perhaps a hyperlink by hand ...

Under linux pdfedit is experimental http://pdfedit.petricek.net/en/index.html

Installed :-) OK, I've just managed to remove a page from a given PDF file. Beyond that one will probably have to know more about PDF ... for example, do you know how pdfedit can help me identify which object in the raw PDF corresponds to a given blob of text on the page? After selecting the blob I get some info on my selection that eludes me :-(

pypdf is a python module at lowlevel. http://pybrary.net/pyPdf/

This looks very interesting!

As exercise, you can try to minimic pdffonts in python with pypdf (pdfs with ttf,otf,type1 etc )

I'm afraid, I don't understand :-( Best, Oliver

Don't forget about pdftk vim plugin, otherwise you'll have to count byte offsets on your fingers, or even better use qdf form with qpdf. Maybe I'll publish a short tutorial on writing pdf by hand that I started to write couple of months ago. AFAIK there isn't any (Please, tell me I'm wrong). Piotr 2009/9/7 luigi scarso :

Under linux, xpdf comes with pdffonts, a cmd line tools that extracts fonts information from a pdf. You can try to mimic it with pyPdf, so your knowledge  can augment .

I've just had a brief look at qpdf and this seems incredible! This might just be the tool I had in mind ... now I'll have to check out what qdf can do for me ...

Please do! Oliver

Good to know ... actually I wanted to peak into a FlateDecode compressed object as my next step. Well, at least I'll know where the smoke might be coming from then :-P Oliver

OK, here it is. But no guarantees it makes much sense. http://okle.pl/blogs/show_post/23 2009/9/8 Oliver Buerschaper :

But you haven't used that on the example file? It's not qdf compliant. P. 2009/9/8 luigi scarso :

I'm sure that hartmut has done a presentation sometimes ago f, could be http://www.matexhu.org/eurotex2006/lectures/pdftex/hartmut-talk.pdf

Wonderful! This is exactly the sort of thing I was looking for ... is there more material similar in spirit? Hartmut? ;-) Oliver

'How does pdf really work' would make a nice Maps article as well (hint hint).

some hint? :-) such things need a quiet week, instead there are reviews over reviews... Regards, Hartmut

Speaking about tools: Acrobat Pro (and some plugins to it) can do a lot.

But all commercial, aren't they?

With podofobrowser those in the know can do a lot.

Will install ;-)

And I'm shamelessly plugging my talk at EuroTeX 2009: http://www.oneiros.de/tex/papers/eurotex2009-pdflibs.pdf

No worries, it's most welcome to me!

Did someone already mention that PDFs are not meant to be editable? Use the source, Oliver. :-)

Will do whenever I can ;-) Oliver
