Show HN: eInk optimized manga with Kindle Comic Converter (+Kobo/ReMarkable)

233 포인트작성자: seam_carver1일 전

Kindle Comic Converter optimizes comics and manga for eink readers like Kindle, Kobo, ReMarkable, and more. Pages display in fullscreen without margins, with proper fixed layout support. Its main feature is various optional image processing steps to look good on eink screens, which have different requirements than normal LCD screens. It also does filesize optimization by downscaling to your specific device's screen resolution, which can improve performance on underpowered ereaders. Supported input formats include folders/CBZ/CBR/PDF of JPG/PNG files and more. Supported output formats include MOBI/AZW3, EPUB, KEPUB, and CBZ.Hey everyone! I'm the current maintainer of KCC since 2023, thanks for using it! I’ve been reading manga on Kindle ever since I got the big 9.7” Kindle DX from 2010 using mangle, and upgraded to the even bigger 10.2” Kindle Scribe 2022 using KCC.The biggest contributions I've made to KCC are:- added modern macOS support and removed homebrew requirement - ported code to run on native Apple silicon M1 chip and later for a 2x speed boost (qt5->qt6) - free open source windows codesign with SignPath - fixed Kindle Scribe support - and tons of other various features and bug fixes and developer friendly changes - created a legacy Windows 7 build with 300+ downloads…The biggest community PRs were:- huge 2x speed boosts due to various CPU/IO optimizations - Kobo/Remarkable supportEnjoy using KCC and let me know if you have any questions!

I would highly recommend that anyone interested in reading manga on an e-reader check out the boox page: <a href="https://shop.boox.com/products/page" rel="nofollow">https://shop.boox.com/products/page</a>I have had this for a year and change and use it interchangeably for books and manga. The 7 inch display is sharp and I use CDisplayex to read manga in horizontal mode with both pages displayed to preserve spreads and other multi page layouts. It works like a dream and I've ready literally hundreds of volumes of manga this way. It also natively support FTP and runs Android, so you don't need to do anything special beyond dropping the files on your device.

Super cool. Thanks for maintaining this.I read manga extensively on my Kobo Forma with koreader. I wrote a script with imagemagick to scale, trim, adjust contrast, map to 16 colors, dither, and repack, all without me having to interact with it... something I'm hoping to open-source sometime, although it's very specific to my use case.

Are there any plans to integrate this with calibre? Or is it integrated already?The combination would be quite powerful IMHO.

Also currently looking for a job, let me know if you have a role that fits me! I've done lots of work related to millions of dollars of AWS cost optimization and of course open source Python work.<a href="https://www.linkedin.com/in/alexu2/" rel="nofollow">https://www.linkedin.com/in/alexu2/</a>

Is it weird that I kind of want ePub to ePub support? I have many not Kobo compatible comics/manga from places like Humble Bundle that I need to fix. Ideally I'd like to keep metadata + reading direction and perhaps the table of contents. I suppose I could script something that unzips 'em and then processes them....

Slightly related: I'm currently reading manga on a normal Android tablet using Mihon. I'd love to read on an eInk display, but I'd rather manage my library on device instead of having to use a pc and transferring chapters manually.Does anyone have experience with Anrdoid capable eInk tablets? Are there any good, affordable ones?

Hey thanks for posting this! I'll defintitely check it out.Also, as a somewhat unrelated question: how would you recommend someone go about learning pyqt? I've looked into it briefly and am not really sure what the recommended resources are for this framework.

Looks nice! I'm gonna test it!Feature idea (that I think it doesn't have): a gamma/palette sampler. Takes one page of the source, and generates an output with multiple pages, all for the same source page, but each one using a different gamma and/or palette option. Useful when the source is "difficult" (weird shading, colors...) or it's an unknown device, to find the best configuration.

I have found that the trick to getting optimized kindle display with imagemagick tools is to process pages as individual images, and then use a tool like img2pdf to quickly stitch them together into a pdf file as a simple archive.

Normally I just use Koreader on my Kobo. It crops out the margin automatically which is necessary for the small screen. Then I play with the contrast to make the blacks look like they would on paper. Hate asking people to sell their hard work to me but is there something else that this tool does to make the experience even better?

This sounds great!I never got to reading manga on my Paperwhite 4(?) because the scaling made the text terrible to read (that was with KOReader a few years ago). Does this tool handle this better?

Bookmarking this for when I have some free time. It might get me back to finishing my read through of Berserk.

Curious project! I'd love to check out the samples, but the links don't seem to be working in the README.

Has anyone tried this on a Remarkable? It always seemed like the perfect size for reading comic books/magna.

ty for maintaining kcc, I’ve used it heavily for close to a decade. I definitely noticed the performance boost on my macbook :)

What’s the best screen size for reading manga on an eInk display? I’ve always had issues with the entry level Kindles cutting things off or requiring scrolling to get the bottom section of a page. It’s been a long time since I tried this but I’ve always wanted to get my collection on a Kindle or other reader!
