    pub maps: Vec<(String, BTreeMap<u32, RGBA32>)>,
}

A color interpolator that interpolates between colors in the RGB Color Space.

Fields

points: usize

margin_left: u32

The number of pixels to add to the left of the gradient.

margin_right: u32

The number of pixels to add to the right of the gradient.

margin_top: u32

The number of pixels to add to the top of the gradient.

margin_bottom: u32

The number of pixels to add to the bottom of the gradient.

maps: Vec<(String, BTreeMap<u32, RGBA32>)>

The gradient maps.
