Function fade 

pub fn fade(
    img1: &PhotonImage,
    img2: &PhotonImage,
    start_x: i32,
    end_x: i32,
    start_y: i32,
    end_y: i32,
) -> PhotonImage

Fades one image into another.

For horizontal fading, set both start_y and end_y to the same value. For vertical fading, set both start_x and end_x to the same value. Otherwise, axial fading is applied.

Arguments

• img1 - Image to fade from. Must be the same size as img2.
• img2 - Image to fade to. Must be the same size as img1.
• start_x - Column where the fading begins.
• end_x - Column where the fading ends.
• start_y - Row where the fading begins.
• end_y - Row where the fading ends.

Example

use photon_rs::multiple::fade;
use photon_rs::native::open_image;

let img1 = open_image("img1.jpg").expect("File should open");
let img2 = open_image("img2.jpg").expect("File should open");
let _faded_img = fade(&img1, &img2, 0, 100, 0, 100);
