Content Kindle Comic Converter - Convert comics/manga to MOBI/EPUB

[axu2]

Made a quick comparison between Kindle Store and Kindle Comic Converter (Humble Bundle PDF source) versions of Blue Lock Vol. 1.

The huge margins and incorrect black levels in the Kindle Store are notable.
And here's a comparison between Kindle Store and 1.0(Disabled) gamma:



And just a general rant about black level problems in Store content:

KCC 7.5 is out.

1) Kindle Scribe 2480 support has been added, enjoy 300 PPI
2) more immersive two page spread handling when partially checked
3) tons of bug fixes, especially for macOS 15
4) File Fusion option for combining files (community PR)
5) Set Title from ComicInfo.xml option (community PR)

and more!

Video comparison of 1920 vs 2480:



I also opened a Ko-fi! It's taken a lot of my time and energy to make KCC as good as it is today, donations are always appreciated. https://ko-fi.com/eink_dude

KCC 8.0 is out.

1) on macOS, p7zip has been replaced with sevenzip, which is faster and less buggy
2) offered option for original rotate before split behavior
3) fix macOS 15 external EXFAT drives
4) CBZ subfolders only renamed if Kobo would sort incorrectly otherwise
5) faster/more accurate color detection (community PR)
6) optimized image bit depth (community PR)
7) much faster png mobi processing (community PR)
8) output folder option (community PR)
9) avif input

and more bugs that snuck in 7.5

Hey,

Is it possible to remove watermark that is beyond the margin using KCC?

Due to this watermark, tha manga page is not in full screen.

An example is attached. The watermark in on bottom right.

The page number crop option is the best it can do.

But no Kindle/Kobo/ereader is narrower than that image, so even if that watermark was cropped out, it would still look the same and be fullscreen top to bottom.

[axu2]

Searching for testers of a new much sharper color eink rainbow eraser algorithm.

Instead of a global blur, this takes into account the shape of the color filter array.



Just for convenience, links to the test builds with new rainbow algorithm:

https://github.com/axu2/kcc/releases/tag/v8.0.4-major
https://github.com/axu2/kcc/releases/tag/v8.0.4-minor

You probably want the major build unless you have kobo Libra colour.

If you test please tell us your device model and which build works for you.

hmmm i see, thank you for replying.

what about the cropping power? does it do something related to that?

because having the watermark removed, it would allow the image (manga page) to be fullscreen left to right.

[axu2]

A higher cropping power with page number crop option on might crop more.

Feel free to test.

I don’t see how you can have it full screen left to right. The image already fills it top to bottom in portrait mode.

Or are you stretching the image making it wider than intended? So it’s full screen in all 4 directions?

Maybe a picture of your device will make the problem clearer.
