#magick_color_stop(offset, color) ⇒ Compass::Magick::Types::ColorStop

Creates a new Types::ColorStop instance.

Parameters:

  • offset (Sass::Script::Number) —

    The color stop offset, 0-100.

  • color (Sass::Script::Color) —

    The color at the offset.

Returns:

  • (Compass::Magick::Types::ColorStop) —

    A type that is used when constructing gradients to control color stops.
