KindleComicConverter
=============
KindleComicConverter
KindleComicConverter is a MacOS X AppleScript droplet to convert image folders to a comic-type Mobipocket ebook to take advantage of the new Panel View mode on Amazon's Kindle.
REQUIREMENTS
-------------
- kindlegen in /usr/local/bin/
- [http://www.rarlab.com/download.htm](unrar) and [http://developer.berlios.de/project/showfiles.php?group_id=5373&release_id=18844](rarfile.py) for calibre2ebook.py automatic CBR extracting
USAGE
-------------
Drop a folder over the droplet, after a while you'll get a comic-type .mobi to sideload on your kindle.
The script takes care of calling comic2ebook.py, kindlegen and kindlestrip.py.
For the standalone comic2ebook.py script, please refer to CLI help.
WARNING: at the moment the script does not perform image manipulation. Image optimization and resizing (HD Kindles want 758x1024, non-HD ones 600x800) is up to you.
CREDITS
-------------
