ASE.rb

A general purpose library for reading and writing Adobe Swatch Exchange files in Ruby. ASE files can be used across the entire Adobe Creative Suite (Photoshop, Illustrator, etc).

Installation

Add this line to your application's Gemfile:

gem 'ase'

And then execute:

$ bundle

Or install it yourself as:

$ gem install ase

Usage

Writing

doc = ASE.new

palette = ASE::Palette.new('My Colors')
palette.add 'Black', ASE::Color::RGB.new(0, 0, 0)
palette.add 'Red', ASE::Color::RGB.from_hex('#ff0000')
palette.add 'Blue', ASE::Color::CMYK.new(0.92, 0.68, 0.2, 0)
palette.add 'Light Gray', ASE::Color::Gray.new(0.75)

doc << palette
doc.to_file('path/to/file.ase')

Reading

doc = ASE.from_file('path/to/file.ase')

puts doc['My Colors']['Red'].to_a
#=> [255, 0, 0]

puts doc['My Colors'].size
#=> 2

Notes

• If the ASE file does not define a palette, and instead simply lists colors, ASE.rb will use :default as the palette name.
• ASE.rb does not support LAB colors yet.
• Because reading & writing CMYK/LAB colors is dependent on your color profile, the output might be different than what is shown in an Adobe application. Color profile support might be added in the future.
• Gray and Grey are interchangeable in ASE.rb
