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

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.

Also pdftk
But, it is naive to believe that a pdf can be "protected" from copying or extracting, isn't it?

indeed, in a similar fashion as copy protected cd (by making then fagile
for reading on computers) ... 100 years form now they will either laugh
at us or wonder if we could not do better than that
