Convert Adobe Photoshop curves files into polynoms, for further use with image processing libraries (ImageMagick, Javascript canvas, etc.)

gem install curver

Or in Gemfile :

gem 'curver'

acv = Curver.new('path/example.acv')
acv.polynoms

You can specify the polynom_degree, the max_value that you want, or the polynom_precision. By default :

Curver.polynom_degree    = 6
Curver.max_value         = 255 
Curver.polynom_precision = 3   

255 is the max_value used for ImageMagick. For canvas image processing, max_value of 1 is more convenient.
