To split a Comic / Manga volume into its chapters, run python ExtractChaptersFromVolume.py. If you are on Linux, you may need to replace python with python3

For the extraction to work, the filenames of your volume's images should look something like:

Series Title - c001 (v01) - p000 [optional chapter title] [some other stuff that doesn't matter].png

Series Title - 001x2 [optional chapter title] [some other stuff that doesn't matter].png

Series Title - 001 (v01) - p000 [some other stuff that doesn't matter] [optional chapter title].png

What's important is the c001 (v01) pattern. As long as the filenames follow it, or another commonly used format, your files should parse just fine

If the chapter title is part of an image's filename, and you want it added to the filename of the chapter, use the p / --parse argument to enable parsing, and pass the chapter title's index (which starts at 0) with -i / --index

Only the first file of each chapter will have its title parsed

Examples:

• Series Title - c001 (v01) - p000 [Chapter Title] [sometingelse].jpg To get the chapter title, use -i 0
• Series Title - c002 (v01) - p000 [sometingelse] [Chapter Title].jpg To get the chapter title, use -i 1

A negative index can also be used when there are an inconsistent amount of bracketed text to the left of the title:

• Series Title - c001 (v01) - p000 [sometingelse] [Chapter Title].jpg
• Series Title - c002 (v01) - p000 [sometingelse] [sometingextra] [Chapter Title].jpg To get the chapter title for both, use -i -1

To bulk-add metadata to your chapters, I highly recommend ThePromidius's Manga-Manager and / or my BatchComicTagger, which can also scrape metadata from some Fandom wikis
