Tiling Images

We can repeatedly draw one image to fill another image. This can be done by tile. In the following example, we use image resize.jpg, which was created in previous tutorials, as a pattern to draw on another image, my_image.jpg. For ease of demonstration, the content of my_image.jpg will be ignored and completely replaced. We only use the dimension of my_image.jpg.

use image::imageops;

fn main() {
    let mut img1 = image::open("my_image.jpg").unwrap();
    let img2 = image::open("resize.jpg").unwrap();

    imageops::tile(&mut img1, &img2);
    
    img1.save("tile.jpg").unwrap();
}
