<brief_description>
A color transition.
</brief_description>
<description>
This resource describes a color transition by defining a set of colored points and how to interpolate between them.
See also [Curve] which supports more complex easing methods, but does not support colors.

<methods>
<method name="add_point">
<return type="void" />
<param index="0" name="offset" type="float" />
<param index="1" name="color" type="Color" />
<description>
Adds the specified color to the gradient, with the specified offset.
</description>
</method>
<method name="get_color">
<return type="Color" />
<param index="0" name="point" type="int" />
<description>
Returns the color of the gradient color at index [param point].
</description>
</method>
<method name="get_offset">
<return type="float" />
<param index="0" name="point" type="int" />
<description>
Returns the offset of the gradient color at index [param point].
</description>
</method>
<method name="get_point_count" qualifiers="const">
<return type="int" />
<description>
Returns the number of colors in the gradient.
</description>
</method>
<method name="remove_point">
<return type="void" />
<param index="0" name="point" type="int" />
<description>
Removes the color at index [param point].
</description>
</method>
<method name="reverse">
<return type="void" />
<description>
Reverses/mirrors the gradient.
[b]Note:[/b] This method mirrors all points around the middle of the gradient, which may produce unexpected results when [member interpolation_mode] is set to [constant GRADIENT_INTERPOLATE_CONSTANT].
</description>
</method>
<method name="sample">
<return type="Color" />
<param index="0" name="offset" type="float" />
<description>
Returns the interpolated color specified by [param offset].
</description>
</method>
<method name="set_color">
<return type="void" />
<param index="0" name="point" type="int" />
<param index="1" name="color" type="Color" />
<description>
Sets the color of the gradient color at index [param point].
</description>
</method>
<method name="set_offset">
<return type="void" />
<param index="0" name="point" type="int" />
<param index="1" name="offset" type="float" />
<description>
Sets the offset for the gradient color at index [param point].

<member name="colors" type="PackedColorArray" setter="set_colors" getter="get_colors" default="PackedColorArray(0, 0, 0, 1, 1, 1, 1, 1)">
Gradient's colors returned as a [PackedColorArray].
[b]Note:[/b] This property returns a copy, modifying the return value does not update the gradient. To update the gradient use [method set_color] method (for updating colors individually) or assign to this property directly (for bulk-updating all colors at once).
</member>
<member name="interpolation_color_space" type="int" setter="set_interpolation_color_space" getter="get_interpolation_color_space" enum="Gradient.ColorSpace" default="0">
The color space used to interpolate between points of the gradient. It does not affect the returned colors, which will always be in sRGB space. See [enum ColorSpace] for available modes.
[b]Note:[/b] This setting has no effect when [member interpolation_mode] is set to [constant GRADIENT_INTERPOLATE_CONSTANT].
</member>
<member name="interpolation_mode" type="int" setter="set_interpolation_mode" getter="get_interpolation_mode" enum="Gradient.InterpolationMode" default="0">
The algorithm used to interpolate between points of the gradient. See [enum InterpolationMode] for available modes.
</member>
<member name="offsets" type="PackedFloat32Array" setter="set_offsets" getter="get_offsets" default="PackedFloat32Array(0, 1)">
Gradient's offsets returned as a [PackedFloat32Array].
[b]Note:[/b] This property returns a copy, modifying the return value does not update the gradient. To update the gradient use [method set_offset] method (for updating offsets individually) or assign to this property directly (for bulk-updating all offsets at once).

<constants>
<constant name="GRADIENT_INTERPOLATE_LINEAR" value="0" enum="InterpolationMode">
Linear interpolation.
</constant>
<constant name="GRADIENT_INTERPOLATE_CONSTANT" value="1" enum="InterpolationMode">
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.
</constant>
<constant name="GRADIENT_INTERPOLATE_CUBIC" value="2" enum="InterpolationMode">
Cubic interpolation.
</constant>
<constant name="GRADIENT_COLOR_SPACE_SRGB" value="0" enum="ColorSpace">
sRGB color space.
</constant>
<constant name="GRADIENT_COLOR_SPACE_LINEAR_SRGB" value="1" enum="ColorSpace">
Linear sRGB color space.
</constant>
<constant name="GRADIENT_COLOR_SPACE_OKLAB" value="2" enum="ColorSpace">
[url=https://bottosson.github.io/posts/oklab/]Oklab[/url] color space. This color space provides a smooth and uniform-looking transition between colors.
