Option of having black borders for fixed page books?

jackm8 · 07-29-2024, 02:16 PM

Does anyone know if it's possible to contact Amazon regarding features of their devices?

I'd really appreciate one simple fix. Ability to have black borders instead of white for fixed page books in pdf, or fixed kfx format. As it is, you always get white extra space on books that are not in exact 3:4 aspect ratio, and it just doesn't look as good, since it's ruining the intended look of some books.

(but don't hold your breath)

Does any PDF reader on any device have this option?

Well, there are a few solutions. It's how I got to like them. Dark mode can do black borders at times in comic mode. It's pretty buggy, and not always reliable. Then there's making them yourself beforehand.

— Extract pdf pages as images.
— Add black borders to images. (I use batch convert tool in Faststone using these settings, modifying resolution to target device)
— Convert images back to pdf.

You could use kindle comic converter with the black border option if your pdf is image based.

You could convert a normal pdf to images with mutool.
