Description
-----------

Given a set of colors, this node will interpolate them in order, meaning, that if you have color 1, color 2 and color3, the ramp will interpolate (generate the colors between two colors) from color 1 to color 2 and from color 2 to color 3. Initially the ramp will have 2 colors (black and white), one (black) at ramp lower offset offset 0 and the other (white) at the ramp higher offset 1.

Member Function Description
---------------------------

.. _class_Gradient_add_point:

- void  **add_point**  **(** :ref:`float<class_float>` offset, :ref:`Color<class_color>` color  **)**

Adds the specified color to the end of the ramp, with the specified offset

.. _class_Gradient_get_color:

- :ref:`Color<class_color>`  **get_color**  **(** :ref:`int<class_int>` point  **)** const

Returns the color of the ramp color at index *point*

.. _class_Gradient_get_colors:

- :ref:`PoolColorArray<class_poolcolorarray>`  **get_colors**  **(** **)** const

Returns the colors in the ramp

.. _class_Gradient_get_offset:

- :ref:`float<class_float>`  **get_offset**  **(** :ref:`int<class_int>` point  **)** const

Returns the offset of the ramp color at index *point*

.. _class_Gradient_get_offsets:

- :ref:`PoolRealArray<class_poolrealarray>`  **get_offsets**  **(** **)** const

Returns the offsets for the colors in this ramp

.. _class_Gradient_get_point_count:

- :ref:`int<class_int>`  **get_point_count**  **(** **)** const

Returns the number of colors in the ramp

.. _class_Gradient_interpolate:

- :ref:`Color<class_color>`  **interpolate**  **(** :ref:`float<class_float>` offset  **)**

Returns the interpolated color specified by *offset*

.. _class_Gradient_remove_point:

- void  **remove_point**  **(** :ref:`int<class_int>` offset  **)**

Removes the color at the index *offset*

.. _class_Gradient_set_color:

- void  **set_color**  **(** :ref:`int<class_int>` point, :ref:`Color<class_color>` color  **)**

Sets the color of the ramp color at index *point*

.. _class_Gradient_set_colors:

- void  **set_colors**  **(** :ref:`PoolColorArray<class_poolcolorarray>` colors  **)**

Sets the colors for the specified amount of elements. Calling this function with a different number of elements than previously defined causes the ramp to resize its colors and offsets array to accommodate the new elements.

.. _class_Gradient_set_offset:

- void  **set_offset**  **(** :ref:`int<class_int>` point, :ref:`float<class_float>` offset  **)**

Sets the offset for the ramp color at index *point*

.. _class_Gradient_set_offsets:

- void  **set_offsets**  **(** :ref:`PoolRealArray<class_poolrealarray>` offsets  **)**

Sets the offset for the specified amount of elements. Calling this function with a different number of elements than previously defined causes the ramp to resize its colors and offsets array to accommodate the new elements, all new colors will be black by default.
