Is it possible to define dark mode for pdf?
Just the ability to define the page background and page text color would be helpful.

Greetings,
Marek

Hi Marek

There's not a simple way to do to that with PDFium, you'd need to modify the color of all the text on the page and insert a dark rectangle behind all of the page objects.

Another option would be to apply some effect as the page is shown in the OnDrawCanvas event:
