Expand description

Fill the image with a linear vertical gradient

This function assumes a linear color space.

§Examples

use image::{Rgba, RgbaImage, Pixel};

let mut img = RgbaImage::new(100, 100);
let start = Rgba::from_slice(&[0, 128, 0, 0]);
let end = Rgba::from_slice(&[255, 255, 255, 255]);

image::imageops::vertical_gradient(&mut img, start, end);
img.save("vertical_gradient.png").unwrap();
