defmodule Image.Plug.Pipeline.Ops.Tint do

  @moduledoc """

  Single-colour tinted-monochrome operation.



  The image is desaturated and the resulting luminance is scaled

  by the requested tint colour: white pixels become the tint

  colour, black pixels remain black. Maps to imgix's

  `monochrome=<hex>` and ImageKit's `e-monochrome=<hex>`.



  `:color` is normalised to a 3-element `[r, g, b]` 0..255 list

  by the provider parser.
