i'm using Ubuntu 9.10.
I have severalo PDFs of old books, in which the pages have turned yellow.
I know how to adjust that yellow in individual pictures. Is there some way
of adjusting it across a total pdf file?
I could take the files apart (pdftoppm) and do each individual picture, a
pain when the numbers get up to 500+, and I've had trouble getting the pdfs
back, together again. Besides that, when I do, I lose the ability to search
Any help would be appreciated.
