Tankobon lets you batch rename, resize and change colorspace for manga scans in order to make them optimal for consumptions on ebook readers.

Just call the binary like this:

tankobon recipe

where recipe is a text file defining some options.

Tankobon uses recipe files to define what kind of actions you want the script to perform for you. Here is an example of a recipe file:

files = <<-FILES
Eden - It's An Endless World! v03 (2006) (case-DCP).zip
Eden - It's An Endless World! v04 (2006) (case-DCP).zip
FILES
.split("\n").each {|s| s.strip!}

with_base '~/Downloads/Eden/', files
sanitize
convert

Takes the listed files in the directory and sanitizes and converts them with the default sanitizer and converter.

You can choose a different converter by passing it to the convert method, you need to pass a Tankobon::Converter subclass. See lib/tankobon/converter.rb for the default KindleDXConverter implementation. A smart approach is inlining an anonymous subclass. For example:

convert Class.new(Tankobon::Converter) do
  def width; 824; end
  def height; 1200; end
  def format; "png"; end
  def colorspace; "RGB"; end
end
