No. Flattening PDFs means to "burn in" comments and the contents of form fields 
from editable to page content.

The only way to "protect" contents from editing are the password settings. 
There are free tools to set them, but AFAIK no open source tools except maybe 
libraries.
There’s also pdfcrack to find out passwords.

Not at all.

[NTG-context] How do I compile a "flat" pdf?

2016-10-07 Thread Bomber K. 

Hi guys,

I am trying to create a pdf which contains some graphics that I created. 
I want to pass my PDF digitally but I don't want users to be able to 
right-click on a gfx and save it. I think this is called "flattening".
Is there a way in CTX to create such a file or do I have to recompile 
the PDF with 3rd party software?
Is there maybe even a way to flatten only specific objects like, only 
one picture of many or all, and leave form fields unflattened?


Thanks, Sebastian
