I am creating a PDF that is designed for viewing on Screens/Tablets, and uses white Text on black background. Since some readers might want to print it, and I want to avoid to create a second PDF, I would like to include a Print View as Layer in the PDF.
How can I make (xe)latex to render the same Text twice above each other, with a background image in between, so I can use the upper text layer and image as one PDF-Layer to disable it?
So in the PDF, it would be the following order of layers (read it bottom-to-top):
WHITE TEXT \ > OCG Layer #1 BLACK BACKGROUND / BLACK TEXT \ > regular PDF WHITE BACKGROUND /
Now if the reader hides Layer #1 in the PDF Reader, the printerfriendly Version below it becomes visible.
