Defined in:
lib/spritely/options.rb

Overview

Provides a simpler method of querying a particular image’s options. Rather than each ‘Image` needing to know how to parse the keyword arguments passed into the `spritely-map` function, this simplifies and de-duplicates the passed option keys.

$application-sprite: spritely-map("application/*.png",
  $arrow-repeat: true,
  $arrow-spacing: 10px,
  $another-image-position: right,
  $spacing: 5px
);

The options passed in above will be easily accessible via an instance of this class.

options['arrow'] => {repeat: true, spacing: 10}
options['another-image'] => {position: 'right', spacing: 5}
