I need to invert all the colors of a PDF document (background, text, graphics, and images). I want it persistent in the file so the inverted viewing options, that some viewers offer, won't help.
Rasterizing the document and using image manipulation software is also not an option.
I read somewhere that this can be done with the Enfocus PitStop plugin for Acrobat. However I didn't see a corresponding command anywhere. Am I missing something?
Then I read that the ARTS PDF Crackerjack plugin for Acrobat offers negative printing so I tried that, too. The option is there but it simply doesn't work.
I have been searching for very long for a way to do this. It seems like a common enough task but I just can't find out how to do it.
Are there maybe any virtual printer drivers or something of the sort that support negative printing?
Can anyone help?
