Someone I support has a pdf with a too dark background and is having trouble reading it. By using the controls in Okular I can make it black font on white background, and its perfect, easy to read and straightforward.
However, I can't figure out how to either export a copy with the changes, or make the same changes in some other package.
To make the changes I used the accessibility options in Okular's configure control, and did convert to black and white, then threshold about 75% and contrast 100%. Okular remembers to apply this on my machine when the file is opened, but how to make the changes to the file itself so that other readers show the same thing?
Any suggestions?
