v0.2.0

NEW .opacity Method

Added an .opacity method to set the opacity of a color. (credit @matildasmeds)

'red'.paint.opacity(0.3).to_rgb #=> 'rgba(255, 0, 0, 0.3)'

v0.1.0 - 2016-05-26

Dynamic Custom Palettes

You can generate custom palettes on the fly without predefining them now. The old way of defining them with a name via Chroma.define_palette still works too.

# New dynamic way
'red'.paint.custom_palette do
  spin 60
  spin 180
end

#=> [red, yellow, cyan]

v0.0.1 - 2015-01-14

Method Changes:

  • Renamed options for analogous palette method.
    • :results -> :size
    • :slices -> :slice_by
  • Renamed option for monochromatic palette method.
    • :results -> :size

Miscellaneous Changes:

  • Add remaining specs for public API.
  • Add "transparent" as color name for Chroma.paint.
  • Minor API doc example fixes.
  • Add public API usage examples to README.

[v0.0.1.alpha.3] - 2015-01-13

Bug Fixes:

  • Fix bug where Color#complement didn't return a color of the same format.
  • Fix bug where palettes did not have the same format as the seed color. (#16)
  • Fix bug where the helper method bound01 was not always producing accurate results for percentages due to integer division.
  • Fix bug where a Color created from an rgba string (e.g. 'rgba(255, 0, 0, 0.5).paint') was not serializing to an rgba string from to_s. (#17)

Method Changes:

  • Add Color#format method to return @format instance variable.
  • Change arguments for analogous and monochromatic to option arguments.
  • Add ability to output palette as an array of color format strings via the :as option. (#10)
  • On Color rename greyscale to grayscale and alias greyscale back to grayscale.

Miscellaneous Changes:

  • Introduced custom errors and replaced raise calls with them.
  • Added API doc headers. (#4)

[v0.0.1.alpha.2] - 2015-01-13

Bug Fixes:

  • Fixed bug with number of arguments passed to generator classes in RgbGenerator. (#1)
  • Make FromHexStringValues.from_hex8 take alpha as second parameter instead of last. Fixes incorrect color generation from hex8. (#6)
  • Ensure that string serialization rounds the alpha value where applicable. (#7)
  • Fix bug where to_s and inspect would return <unknown> instead of using hex if the format was :name and the named color could not be found. (#2)
  • Fix bug where Color equality wasn't implemented. (#12)
  • Fix bug where passing in an instance of Hsl or Hsv to Color.new caused their values to get changed. (#11)
  • Fix bug with Color equality being off due to floating point math. (#13)
  • Fix bug where Color instances generated from hsla and hsva strings had the wrong alpha value. (#15)

Method Changes:

  • Add optional hex_for_unknown parameter to Color::Serializers#to_name. If true, it allows to_name to default to hex string if name is not found instead of returning '<unknown>'. (#2)
  • Add missing conversion methods to converters (a12244f0d81c9480490cfb8a472993f54dd9fbd2)
  • Add equality (eql? and ==) methods to Color class and ColorModes classes. (#12, #13)
  • Add Chroma.define_palette for defining custom palettes. (#9)
  • Add Color#paint method for returning itself. (#14)
  • Tweak Color serialization method names. Switched to this naming primarily to drop the *_s on the string serialization methods.
    • to_hsv -> hsv
    • to_hsv_s -> to_hsv
    • to_hsl -> hsl
    • to_hsl_s -> to_hsl
    • to_hex -> to_basic_hex (made private)
    • to_hex_s -> to_hex
    • to_hex8 -> to_basic_hex8 (made private)
    • to_hex8_s -> to_hex8
    • to_rgb -> rgb (moved attr_reader to serializers and made public)
    • to_rgb_s -> to_rgb
    • Removed to_name_s alias

[v0.0.1.alpha.1] - 2015-01-11

  • Initial release
