Are you talking about the macOS flicker issue on eink? I've heard it was fixed by the Stillcolor app, and there's a video of it fixing the eink flicker issue here: https://www.youtube.com/watch?v=siufMXZ4tN8&t=17s

The kindle pdf renderer is much slower than the mobi/azw3 renderer and isn’t full screen.
seam_carver··on Show HN: eInk optimized manga with Kindle Comic Converter (+Kobo/ReMarkable)
Yea, that's true, but it's not as simple as just unzipping the epub, I've found sometimes that the pages aren't named in a sorted order, the order is defined in one of the opf file.

There's a FAQ in the readme about Humble Bundle. I've found that the PDF source is the absolute best quality with the least amount of resizing artifacts/moire compared to epub.

Yes, but be aware I didn't write this from scratch, I ported pre-existing qt5 code to qt6. and made modifications to the UI

I use 10” kindles like the scribe and DX. Bigger than a physical paper volume

KCC is developed on an M2 Mac Mini so I was highly incentivized to make it fast on Apple.
seam_carver··on Show HN: eInk optimized manga with Kindle Comic Converter (+Kobo/ReMarkable)
The main audience of KCC doesn't have access to the powerful features of koreader, but filesize optimization is pretty nice and can get filesizes down significantly.

Cropping whitespace between panels (not just margins on the edge) is also cool. And page number cropping.

This project was my first exposure to Qt, and I just read the official docs.

Considering how ReMarkable support was added by a community member, it probably looks great.

edit: added remarkable 1/2 sample file to link in other comment.

seam_carver··on Show HN: eInk optimized manga with Kindle Comic Converter (+Kobo/ReMarkable)
Oh... the sample links are all dead. They were made by previous KCC maintainer.

For now, here's some kindle scribe samples. The mobi can be usb transferred, the epub can be sent via Send to Kindle. They might look fine on other Kindles, let me know! Otherwise I can put up more samples.

Edit: added more kindles/kobos/remarkable, lmk if I made any errors! only difference is resolution

seam_carver··on Show HN: eInk optimized manga with Kindle Comic Converter (+Kobo/ReMarkable)
You just drag and drop the mobi file into the documents folder on the Kindle.

If you are on macOS, you need the Amazon USB File Manager app to do that on newer MTP based Kindles. Older kindles just used ordinary USB mass storage protocol. Link in readme.

seam_carver··on Show HN: eInk optimized manga with Kindle Comic Converter (+Kobo/ReMarkable)
I personally just do boring USB transfer of files instead. Users have reported issues with Calibre modifying KCC files and breaking the formatting, fixed layout books like comics/manga are different than normal reflowable ebooks.

I only use Calibre for normal ebooks.

Maybe in the future, KCC has command line versions as well. It's all Python.

A recent feature I implemented a few weeks ago was virtual panel view.

You can enable it in the Kindle Aa menu.

You can double tap a corner to zoom into the corner in portrait mode 150% zoom.

Or you can turn the Kindle sideways to read half a page at a time.

and KCC scaling using the LANCOZ algorithm, which looks great.

seam_carver··on If you're in the market for a $1,900 color E Ink monitor, one of them exists now
This is way too expensive. I’ll stick to my Kindle and eink phone for now.

I recorded a video of me reading Hacker News on my eink android phone and Kindle here. It actually works great.

https://youtu.be/onvSjhubvQ8

Apps used are EinkBro browser and Ktool. The browser is an android apk and lets you “page turn” websites with volume buttons. Ktool converts hacker news discussions to well formatted epubs for kindle.

OK, admittedly it does look bad on video, but seeing it in person is a totally different experience.

1) Rapidly changing between apps without pressing the manual refresh button is a little unrealistic usage. Also, the ghosting is way less noticeable in person vs the camera recording here. The contrast looks great in person, similar to the contrast of ink of paper.

2) eInk screen technology is way easier on the eyes for me. I can read on it basically continuously. There's no backlight, it's entirely ambiently lit so usage in direct sunlight is easy. The technology works by physically moving ink particles around and looks like ink on paper. there's also optional front lights for use in darker environments but it's usually off.

The top bar is a CSS issue. I forgot to enable the black and white only mode in the einkbro browser. Since I rarely look at top bar it slipped my mind.

Here's what it looks like with black/white mode:

I love eInk. It's so nice to look at compared to normal LCD screens. I got an eInk phone, which is much cheaper than these full sized monitors though.

seam_carver··on Show HN: eInk Manga with Kindle Comic Converter (+Kobo/ReMarkable)
Kindle Comic Converter optimizes comics and manga for eink readers like Kindle, Kobo, ReMarkable, and more. 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 file size optimization by downscaling to your devices native resolution, which helps 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 support.

Enjoy using KCC and let me know if you have any questions!
