Henskan is a image converter and optimizer built for reading Manga on the Amazon Kindle and other E-ink (like Kobo) devices written in Python. With this application you can easily:
- Load & sort images from directories
- Split (if double page scans), convert into grayscale to save space and improve contrast.
- Manga:
-
- Automatically enhance your image by removing useless white border, so making scan bigger on e-reader.
-
- Automatically rotate images if needed.
- Webtoon:
-
- Automatically smart split the vertical images into pages that are readable on e-reader
It is based on the previous project Mangle, which is no longer maintained.
I tried KCC and Mangle, and found that Mangle was far easier and efficient to use than KCC.
After provide some patchs and features to Mangle, this project was archived by its author. So I decided to fork it and continue the development as Henskan (based on the word "Henkan" which means "conversion" in Japanese).
I simplify a lof the UI, remove some features that I don't use, and add some new ones. I also try to make the code more readable and maintainable. I added a lot of feature to auto-detect manga/webtoon, and also to auto-enhance the images based on their colors/greyscale, and detect the name automatically.
Note that Kindle output (pdf) will also have automatically generated table of content (there is no such feature in the CBZ format for Kobo).
- Just drag & drop you Manga/Webtoon directory on the application.
- Check if the autodetections are ok: split or not, manga/webtoon name detected, etc
- Select your E-reader model (Kindle or Kobo)
- Select the export directory if you want to change
- Export your images
- Enjoy your Manga :)

- finish the PDF for Kobo (and bench it)
- try and help user on the webtoon directory, and image cleaning
- show in the readme how the smart cut is done
