Disable all "enhancements"

[q3cpma]

I'm primarly using my kobo aura hd to read mangas, and I already do a lot of post processing in imagemagick before, so I want to disable all resizing and enhancements:

• How to disable the contrast thing? By looking at the segmented bar, I couldn't guess what was the setting equivalent to "disabled".
• Is there a way to prevent all resizing? I'm currently using zoom set to "fit page".
• Are there other things I don't know of?

• It looks like the second (1.0) is the default contrast.
• Hm, interesting question. There has to be in MuPDF, but there doesn't seem to be an option in the GUI.
• Poor image quality in epub files... #1833 maybe? :-)

• Thanks.
• As long as "fit to page" does what it does, I don't thinks it's a problem.
• Definitely the kind of thing I don't want, since I already reduce depth and dither with Floy-Steinberg.
  Another quite unrelated question: any way to disable scrolling mode for all documents? I find it pretty annoying. I suppose cropping is only used when zoom is set to "something to content", right?

[Frenzie]

Scroll mode isn't the default, so, um, I don't quite understand the question? But you can set (different) global defaults by long-pressing.

And yes, there should be no cropping unless you choose cropping.

Ah thanks, the long pressing thing wasn't obvious. (it's the default here, though).

PS I'd stick to CBZ for comics (not EPUB), regardless of any potential dithering concerns related to the now closed issue I referenced before.

I'll close this one now too.
