How to print pdf file with layers

[balazsati]

Hi!

Can I add my elements to a pdf file sorted to layers? I want to specify each layer's name and visibility? Is it possible somehow?
Thanks in advance,

Attila

@balazsati You can't do that with Qt as far as I can tell. You could possibly achieve that by using 3rd party library with Qt bindings (poppler, QPdf) but not Qt alone.

Hi
Layers came with PDF version 1.5. PDF and more formally known as Optional Content Groups (OCG) and as far as i know poppler supports it
https://github.com/davidben/poppler/blob/master/poppler/OptionalContent.cc
But i never tried it.

Thanks, so that's why I did not find anything. Maybe I will try opendesign's solution.
