Instance Method Summary

• #<<(stop : GradientStop)

  Adds a stop to the gradient given a GradientStop.

• #==(other : Gradient)

  Checks whether or not this gradient is equal to another based on its low-level C counterpart.

  Adds a stop to the gradient.

• #add_stop(offset : Float64, color : RGBA64)

  Adds a stop to the gradient.

• #add_stop(stop : GradientStop)

  Adds a stop to the gradient given a GradientStop.

• #extend_mode

  Fetch this gradient's extend mode.

• #extend_mode=(extend_mode : ExtendMode)

  Set this gradient's extend mode.

• #finalize

  Called when Crystal's garbage collector collects this instance.

• #index_of(offset : Float64) : Int32
