A place to share alternatives to popular online services that can be self-hosted without giving up privacy or locking you into a service you don't control.

Rules:

  1. Be civil: we're here to support and learn from one another. Insults won't be tolerated. Flame wars are frowned upon.

  2. No spam posting.

  3. Posts have to be centered around self-hosting. There are other communities for discussing hardware or home computing. If it's not obvious why your post topic revolves around selfhosting, please include details to make it clear.

  4. Don't duplicate the full text of your blog or github here. Just post the link for folks to click.

  5. Submission headline should match the article title (don’t cherry-pick information from the title to fit your agenda).

  6. No trolling.

Does anyone here know a self hostable service (or a demo of someone else hosting it) which can split common .cbr filetype to a .cbz or other filetype to split the panels?

So for example the 1 image I put with this post, would be 8 seperate images (pages).

That would ideally somehow make the comic books readable on a (somewhat old) black and white travel-Kobo...

isnt this more of an image vision task than a simple utility task?

I'd be amazed if each of those panels coordinates were annotated somewhere

the coordinates aren't there i think, but there are github projects out there that "detect" the panels and suggest split based on that. For most of the panels of most of the comics, that would be more than enough to do a clean split. I just can't find a real relatively easily deployable service that incorporates it.

Just following your above link, you could pre-convert your comics using this: https://framagit.org/nicooo/kumiko
