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…

This isn’t a thing because there are many comics that don’t adhere to “frames”. They overlap with others, use the whole page, etc.
But beyond this, decompress your CBR/cbz files and use imagemagick to find frames and isolate them.
Even in the page given as an example here there are two speech bubbles that are pushing their boundaries.
This is a thing. It just doesn’t work very reliably for the reasons you mentioned.
It does work kind of ok on some comics like the one OP shared and generally pretty well on manga since that tends to be more consistent with the boxes.
I don’t know of anything open source or self hosted that does this though.
This sort of thing ain’t my bag baby.
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
Both cbr and cbz are just compressed archives - R for Rar and Z for Zip. The format has got nothing to do with how the images are displayed in a reader application.
If you want any reader to read a comic frame by frame instead of page by page, you’d have to uncompress the file, then cut out each individual frame and give them sensible names (eg. page_39_frame_03.png or somesuch) and then recompress.
Someone else in the thread mention software that can do this, but it might not always work as expected, when the layout is not straight-forward.
