split-manga-pages

split-manga-pages is a command line utility written in Python that converts your double-page layout manga (or any images in double page layout) to single-page layout. This can make it much easier to read said manga on small screens, such as those found on mobile devices

Installation

Install from pypi: pip install split_manga_pages
You can then run the script: split_manga_pages -h

Usage

Run the executable from the command line with the appropriate command line arguments

Command line arguments

Argument	Required	Description
-d DIR, --directory DIR	yes	Directory containing the image files
-m, --mode	yes	The mode to be used. See Modes
-nk, --no-keep	no	Don't keep the original double page spreads when using detect mode
-h, --help	no	Show help and options for the script

Modes

Support modes are 'all' and 'detect'.

'all'

Treats all images in the directory as double page spreads. Converts them all to single page layouts, i.e. you get twice as many images as you had, and these are put in a directory called split_manga_pages.

'detect'

Uses the resolutions of the images and some simple statistical analysis to determine which images are single page spreads and which are double page. Then splits only the double page images into single page images, and also keeps the original double page image, so you get the original doble page image followed by the two single page images. Images are placed in the orginal directory.

Example

Mode 'all'

I have a folder called manga containing only double page images with names page001.png, page002.png, etc. I run python3 split_manga_pages.py -d manga -m all, and I get a new folder called split_manga_pages containing files page001part1.png1, page001part2.png, page002part1.png, page002part2.png, etc.

Mode 'detect'

I have a folder called manga containing mostly single page images, but every so often there is a double page spread. For example, there are files page001.png, page002.png, and page003.png. page002 is a double spread, whereas the other two are sinlge spread. I run python3 split_manga_pages.py -d manga -m detect, and now in the manga folder I will find files page001.png, page002.png, page002part1.png, page002part2.png, page003.png.
