Gradient

A color interpolator resource which can be used to generate colors between user-defined color points.

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 ramp will interpolate from color 1 to color 2 and from color 2 to color 3. The ramp will initially have 2 colors (black and white), one (black) at ramp lower offset 0 and the other (white) at the ramp higher offset 1.

• colors

Gradient’s colors returned as a PoolColorArray.

• offsets

• void add_point ( float offset, color )

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

• Color get_color ( point )

Returns the color of the ramp color at index point.

Returns the offset of the ramp color at index point.

• int get_point_count ( ) const

• interpolate ( float offset )

Returns the interpolated color specified by .

• void remove_point ( point )

Removes the color at the index point.

• void set_color ( int point, color )

Sets the color of the ramp color at index point.
