Gradient
========
**Inherits:** :ref:`Resource<class_Resource>` **<** :ref:`Reference<class_Reference>` **<** :ref:`Object<class_Object>`
A color interpolator resource which can be used to generate colors between user-defined color points.
.. rst-class:: classref-introduction-group
Description
-----------
Given a set of colors, this resource will interpolate them in order. This means that if you have color 1, color 2 and color 3, the gradient will interpolate from color 1 to color 2 and from color 2 to color 3. The gradient will initially have 2 colors (black and white), one (black) at gradient lower offset 0 and the other (white) at the gradient higher offset 1.
See also :ref:`Curve<class_Curve>` which supports more complex easing methods, but does not support colors.

Enumerations
------------
.. _enum_Gradient_InterpolationMode:
.. rst-class:: classref-enumeration
enum **InterpolationMode**:
.. _class_Gradient_constant_GRADIENT_INTERPOLATE_LINEAR:
.. rst-class:: classref-enumeration-constant
:ref:`InterpolationMode<enum_Gradient_InterpolationMode>` **GRADIENT_INTERPOLATE_LINEAR** = ``0``
Linear interpolation.
.. _class_Gradient_constant_GRADIENT_INTERPOLATE_CONSTANT:
.. rst-class:: classref-enumeration-constant
:ref:`InterpolationMode<enum_Gradient_InterpolationMode>` **GRADIENT_INTERPOLATE_CONSTANT** = ``1``
Constant interpolation, color changes abruptly at each point and stays uniform between. This might cause visible aliasing when used for a gradient texture in some cases.
.. _class_Gradient_constant_GRADIENT_INTERPOLATE_CUBIC:
.. rst-class:: classref-enumeration-constant
:ref:`InterpolationMode<enum_Gradient_InterpolationMode>` **GRADIENT_INTERPOLATE_CUBIC** = ``2``
Cubic interpolation.
