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.
