kcc's Introduction

KCC

Kindle Comic Converter is a Python app to convert comic/manga files or folders to EPUB, Panel View MOBI or E-Ink optimized CBZ. It was initially developed for Kindle but since version 4.6 it outputs valid EPUB 3.0 so despite its name, KCC is actually a comic/manga to EPUB converter that every e-reader owner can happily use. It can also optionally optimize images by applying a number of transformations.

A word of warning

KCC is not Amazon's Kindle Comic Creator nor is in any way endorsed by Amazon. Amazon's tool is for comic publishers and involves a lot of manual effort, while KCC is for comic/manga readers. KC2 in no way is a replacement for KCC so you can be quite confident we are going to carry on developing our little monster ;-)

PREREQUISITES

You'll need to install various tools to access important but optional features. Close and re-open KCC to get KCC to detect them.

7-Zip

Windows 7-Zip

First install the 64-bit x64 version of 7z from https://www.7-zip.org/ or with command line:

winget install --id 7zip.7zip

KCC expects 7z to be installed to the default location at C:\Program Files\7-Zip\.

macOS 7-Zip/Unar

with Homebrew installed

brew install p7zip
brew install unar

KindleGen

Windows / macOS KindleGen

Install Kindle Previewer and kindlegen will be autodetected from it.

INPUT FORMATS

KCC can understand and convert, at the moment, the following input types:

Folders containing: PNG, JPG, GIF or WebP files
CBZ, ZIP (With 7z executable)
CBR, RAR (With 7z executable)
CB7, 7Z (With 7z executable)
PDF (Only extracting JPG images)

USAGE

Should be pretty self-explanatory. All options have detailed information in tooltips. After completed conversion, you should find ready file alongside the original input file (same directory).

Please check our wiki for more details.

CLI version of KCC is intended for power users. It allows using options that might not be compatible and decrease the quality of output. CLI version has reduced dependencies, on Debian based distributions this commands should install all needed dependencies:

sudo apt-get install python3 p7zip-full python3-pil python3-psutil python3-slugify

INSTALL FROM SOURCE

This section is for developers who want to contribute to KCC or power users who want to run the latest code without waiting for an official release.

Easiest to use GitHub Desktop to clone the KCC repo. From GitHub Desktop, click on Repository in the toolbar, then Command Prompt (Windows)/Terminal (Mac) to open a window in the KCC repo.

Depending on your system Python may be called either python or python3. We use virtual environments (venv) to manage dependencies.

If you want to edit the code, a good code editor is VS Code.

If you want to edit the .ui files, use Qt Creator, included in Qt for desktop development. Then use the gen_ui_files scripts to autogenerate the python UI.

Windows install from source

One time setup and running for the first time:

python -m venv venv
venv\Scripts\activate.bat
pip install -r requirements.txt
python kcc.py

Every time you close Command Prompt, you will need to re-activate the virtual environment and re-run:

venv\Scripts\activate.bat
python kcc.py

macOS install from source

One time setup and running for the first time:

python3 -m venv venv
source venv/bin/activate
pip install -r requirements.txt
python kcc.py

Every time you close Terminal, you will need to reactivate the virtual environment and re-run:

source venv/bin/activate
python kcc.py

kcc's Issues

Error when converting large amounts of folders

reported by Arhu:
I tried converting a manga with 103 directories and ~25 images in each directory. Got an error message near the end. Worked fine when I split it in two halves.

Multithread dirImgProcess

Implement multithreading to dirImgProcess to improve execution time.
Each loop iteration is independent, but the execution time of each iteration may be different, so using a thread pool may be indicated:
http://stackoverflow.com/questions/3033952/python-thread-pool-similar-to-the-multiprocessing-pool

[ePub validation] href filename with spaces

Referenced filenames with spaces produce a warning against epubcheck 3.0:

WARNING: comic.epub/OEBPS/Images/Legs - 100 - 059.jpg: Filename contains spaces. Consider changing filename such that URI escaping is not necessary

Find a way to properly use OSX file associations

Current file association code work only for first file.
When trying to open another file when KCC is already started Finder don't trigger KCC code and just move focus to already started instance.

Not found any workaround.

Bug converting blank page

Hi,
i tried to convert this blank page and the program stop working.
(The blank page is attached, but being blank you can't see it XD)

CBZ output support for older Kindles

Older Kindles (1, 2, DX, DXG) don't support "panel view", which was brought by KF8, but can still handle full-screen image viewing from CBZ archives.

That job was fulfilled by Mangle https://github.com/proDOOMman/Mangle

However, it would be nice to see CBZ support back in KCC, since almost everything is still here.

Make window take focus on app launch

Make window take focus on app launch.

Get filetype from magic number

Try to get filetype from magic number (found some CBR that was actually CBZ) and not from extension.

make multiple directories as single output file

Hi, when I download manga using e.g. DomDomSoft Manga Downloader from any site (like mangafox) each chapter has it's own directory. In order to make multi-chapter output file I need to copy all the jpg files into one directory (which also includes changing the name of the files) and then add this one directory to process by kcc. My suggestion would be to implement a flag which would indicate that the passed list of directories should be processed as one output file. Additional nice feature could include creation of chapters in the file based on directories.
The option should be available only for a list of directories.

Wrong visualization in Kindle 3 (Keyboard)

Using KCC for use in Kindle 3 correctly generates the .mobi, but the Panel View is kind of messed up:

Zooming, though, displays page bounds correctly, so I assume it's some issue with OPF options or resolution (converted image for the screenshot is 492x800, attached)

Can't create mobi files (Mac OSX)

When loaded with images/pdf the program will produce a epub file but not a mobi file. The error it gives is provided in the pictures, as well as the system info. Python versions installed Python 2.7.2 and 3.2.3.

sanitize failed if multiple subdir

Seems like slugification did not work if the source cbz contains multiple subdir
this code will fix it:

         @@591
         if name.startswith('.'):
             os.remove(os.path.join(root, name))
         else:
            +sanitizeTree(os.path.join(root, name))
             os.rename(os.path.join(root, name), os.path.join(root, slugify(name)))

Support more input image formats: GIF, TIFF, ...

Hi,

PIL itself supports many file formats: http://effbot.org/imagingbook/formats.htm

KCC should at least support GIF and TIFF (which are common formats for scanned files).
Maybe BMP too?

It's as simple as that:

def getImageFileName(imgfile):
    filename = os.path.splitext(imgfile)
    if filename[0].startswith('.') or\
            (filename[1].lower() != '.png' and
             filename[1].lower() != '.gif' and
             filename[1].lower() != '.tif' and
             filename[1].lower() != '.tiff' and
             filename[1].lower() != '.bmp' and
             filename[1].lower() != '.jpg' and
             filename[1].lower() != '.jpeg'):
        return None
    return filename

Gracefully exit if external executables are missing

Add gracefully exit if no unrar or kindlegen external executables are found.

Choose .epub output path

Add an option for choosing the .epub/.mobi output path.

[ePub validation] non-XML chars in idref attribute

attribute idref in generated content.opf, when containing spaces or other non-XML chars e.g.

<itemref idref="page_Images_Legs - 100 - 038" />

produces the following error on validation by epubcheck 3.0:

ERROR: comic.epub/OEBPS/content.opf(253,49): value of attribute "idref" is invalid; must be an XML name without colons

Add an option to rotate landscape images instead of splitting

Would it be possible to have an option for landscape images to rotate by 90° instead of being split (for devices in portrait mode)?

Slugification failure

In some specific cases sanitizeTree function explode.

Try to convert directory that contain three files:

00000000.jpg
00000.jpg
000.jpg

Quite stupid method of numbering files but it is used in some manga packages.

Panel View zoom should ignore image margins

When margins are added to image due to fact it is too high Panel View should ignore them.

It is possible to implement that but it would require extensive code changes - generating Panel View layout per page not per volume.

Add an option to output to a single file

Occasionally I convert large amounts of chapters and this would definitely help organization.

White/Black borders

Let user to choose between white and black borders when ratio is not the same of device's screen

cx_Freeze: Python error in main script

KCC works fine without KindleGen, but when I launch KCC with it I recieve this error:

Windows 8 x64, KCC 3.2 x64, KindleGen 2.9

I need mobi for my Kindle Paperwhite. Help pls :(

ePub/ZIP repackaging

When repacking the ePub into a single zip, at the moment the zip is created inside the work directory alongside the other files, thus including itself in the archive, with unpredictable behavior (archive is not complete so it can't really be extracted).

The file should be created outside the directory.

Directory and file names are not properly cleaned

Spaces, special characters and other junk corrupt EPUB/MOBI structure.
For example directory "X 33 Possi…bility…" will be added to EPUB but KindleGen will not parse it.
So we can't generate MOBI and created EPUB might fail to load on some devices.

This is C# function used by AWKCC for cleaning entire directory tree.
https://gist.github.com/AcidWeb/6bf480ccdb0e94e91da0

"X 33 Possi…bility…" -> "x-00033-possi-bility"
"Volume 11 - X Y 97 I'm Back" -> "volume-00011-x-y-00097-i-m-back"

Text does not fit in the window when you set higher DPI in you system

I have 15" laptop with 1920x1080 resolution, so I have set up higher DPI in my system (Windows 7: Control Panel -> All Control Panel Items -> Display)

Because of that some of the text in the new GUI does not fit in the window, and the window itself is not resizeable.

It's really low priority thing, as only one string passes out (and maybe the kindle names in select one menu could show more), but I'd be glad if it were addressed at some point ;)
Also the checkboxes in first and second column are not aligned correctly vertically :P

Code optimization in extractCBX functions

(reported by @devernay)

python -m cProfile kcc.py

Most of the time is spent in call and waitpid, and it seems that an external process is called for each page in the book... this is unrar!
calling extractall() instead of extract() in extractCBZ and extractCBR would be much more efficient. Note that a file list can be passed to extractall(), so extractCBX should construct the file list in the loop, and then pass this list to extractall.

Fake Panel View mode for Kindle 3/4 NT

I started work on mode that will emulate Kindle Touch/Paperwhite Panel View.

Improve dithering/output file format settings

Single .mobi file

Hi,

with version 3.3 I got this error:

Panel View customization

As an enachment, is it possible to customize the number of Panels in "Panel View Mode"?
Now is in default 4 "panels"
On page 37 of Amazon Publishing Guidelines (sec 5.4) there is some details

"Natural" sort for files and folders

Reported by Arhu:

Directory- and file names seem to be sorted alphabetically before they are put into the epub file. This doesn't always work, because often directories or files are named like this:

1.jpg
10.jpg
11.jpg
12.jpg
..
2.jpg
20.jpg
..

or manga-1.jpg, manga-10.jpg, ...

Of course they'd end up in the wrong order. Would be nice if those could be sorted by numerical value instead. CDisplay CDisplayEX does it like that I believe.

Add ASIN in created mobi

Add a fictitious ASIN (like calibre does) to prevent Kindle show "Personal" banner.

Image processing order

(followup from #26 )

since cropping and cutting relies on image variance (not mean) in an area (lots of call to ".var" in the code), contrast enhancement actually makes cutting a bit more difficult: if the gain is 1.1, then the variance is multiplied by 1.21 (=1.1*1.1) and has less chances to pass the threshold.

but there's more to come:
dithering is completely wrong !!! I mean really really wrong.

Take the following script, run it on the attached image (or any other image), and check out the results...
The right way to do it is thus

do gamma decompression and image optimization after crop/resize
if dithering is asked for, first convert to Rec601Luminance (Luminance is linear, Luma is computed on gamma-compressed components), THEN quantize

#!/bin/sh -x
KCC=/Users/devernay/Development/Kindle/kcc

# magicboy.jpg was created by convert 000.jpg -resize 600x800 magicboy.jpg

mkdir magicboy
convert magicboy.jpg magicboy/000original.png

# Rec 601 Luma: combine gamma-compressed RGB components. result is gamma-compressed
convert magicboy/000original.png -set colorspace RGB -colorspace Rec601Luma magicboy/001rec601Luma.png

# Rec 709 Luma: combine gamma-compressed RGB components. result is gamma-compressed
convert magicboy/000original.png -set colorspace RGB -colorspace Rec709Luma magicboy/002rec709Luma.png

#Rec 709 Luminance: RGB components are linearized, then combined. result is linearized (looks darker)
# see http://www.imagemagick.org/script/color-management.php

CONCLUSIONS:

from magicboy-nodithering.epub, we notice that PIL is using Rec601 luminance formula, see Convert.c in PIL:
/* ITU-R Recommendation 601-2 (assuming nonlinear RGB) _/
#define L(rgb)
((INT32) (rgb)[0]_299 + (INT32) (rgb)[1]_587 + (INT32) (rgb)[2]_114)

-> it should really use Rec709 since that's what PNG and JPEG use (sRGB), but that's no big deal.

PIL's palette conversion is completely wrong! the quantized color images don't look like original images or like grayscale images.

-> the image should be converted to grayscale BEFORE quantization

Here's the (kludgy) modified applyImgOptimization function which gives the good result.

def applyImgOptimization(img, isSplit=False, toRight=False):
    img.cropWhiteSpace(10.0)
    if options.cutpagenumbers:
        img.cutPageNumber()
    img.resizeImage(options.upscale, options.stretch, options.black_borders, isSplit, toRight)
    img.optimizeImage(options.gamma)
    if not options.notquantize:
        img.image = img.image.convert('L')    # convert to grayscale
        img.image = img.image.convert("RGB")    # convert back to RGB
        img.quantizeImage()

Add PDF to convertable formats

At the moment Imagemagick with ghostscript support seems to be the only way to extract comics from a PDF.

Virtual Panel View in Landscape mode display too big margins.

Margins there could be smaller.
