KCC don't support that. You need to repackage chapters in single ZIP.

Hello AcidWeb, are there any plans for KCC being distributed in elementary os AppCenter? Apparently you can do this seamlessly via GitHub login. Source: https://developer.elementary.io/

I can't find where it supports anything other than GTK+ version 3.

(Grayscale Kindles only have GTK+ version 2 pre-installed. So that distribution point is not much good for things on e-ink Kindle.)

It is never that easy :-P And no - I'm not planning to maintain another Linux release.

Hi everyone,

I just discovered KCC, but it does not work on my version of windows 10 (Pro 64bits).
Basically, I can open it but as soon as I try to open a file or a directory it ceases to function. I did manage to convert one book once though but nothing more.
Is there a known issue with some version of Win 10 ?

Also, I have a macbook pro at home. I was wondering whether there were some tutorials to install KCC with Brew because I haven't been able to make it work for now.
thanks !

One more person had this issue. It look like some QT bug and I can't replicate this problem. I don't have any fix for now.

Additionally if you really using Kindle 2 - output will not look very well.

Ok thanks. I will try on another comp. Maybe on a virtualized Windows on my Macbook.

And what about a Mac tutorial ? Does that exist ?

PS : no, I forgot to change my profile. I just got an Oasis ;-)

Hi, I was wondering something: What would be the optimal PPI to use when exporting PDF pages to PNG to create a CBZ? I was using poppler to find out what PPI was used for each image on every page but it produced huge PNG files (like 10345x15518 pixels), and it takes way too long to do it. If I use ghostscript I can export using a fixed PPI for all pages, and it's much faster. My device is a Kobo Glo HD, which has a 300 PPI screen. Would something like 600 PPI be enough for KCC to use as source?

The highest PPI of any of the grayscale kindles is also 300 ppi.
I haven't looked, but KCC most likely uses one of the common graphic libraries in its conversions.

KCC is open source, you could check what provides the graphic functions:
https://github.com/ciromattia/kcc
From that, you should be able to figure out what the range of the inputs would be 'best' for the conversions.

And the answer is:
It uses the Python Imaging Library:
http://effbot.org/zone/pil-index.htm
Which looks a lot like it is an interface to the imagemagick library.

Using default settings KCC resize all images to device resolution. So as long input files are bigger than that you will be OK. In case of Kobo Glo HD that is 1072x1448.

And it use Pillow not PIL :-) PIL is dead for long, long time.

It sure had me fooled:
https://github.com/ciromattia/kcc/bl...erter/image.py
PHP Code:
from PIL import ImageImageOpsImageStatImageChopsImageFilter 
Although a bit of googling seems to show a module name clash between PIL and Pillow.

But I'll stick to my conclusion - the underlying library is most likely imagemagick.
Which should mean it can handle anything you can imagine.

Would it be possible to add support for DRM-free AZW3 and epub conversion to vice versa e.g. AZW3->ePub and ePub->AZW3? Not for books obviously but for comics in those formats? I know I could go AZW3->Zip->image folder->epub but you lose all metadata. KCC does a really great job making fixed layout ePubs.

Is there at least a way to add metadata using KCC through commandline? I could probably make some script to do most of what I want, though I don't think it'll be as slick.

Could you elaborate? I don't really see scenario when that would be useful.

Buy a comic/manga in AZW3 from Amazon, but want to read it on an ePub device or vice versa. I have hundreds of manga in AZW3 from Amazon Japan but I'd like to read them on a Kobo Aura One. It's also the easiest way to get legit raw manga so I'll probably keep getting them in AZW3.


Converting with Calibre breaks the layouts.

I know this is probably kinda niche but I'd thought I'd ask.
