Function warp_with

pub fn warp_with<P, F>(
    image: &Image<P>,
    mapping: F,
    interpolation: Interpolation,
    default: P,
) -> Image<P>
where
    F: Fn(f32, f32) -> (f32, f32) + Sync + Send,
    P: Pixel + Send + Sync,
    <P as Pixel>::Subpixel: Send + Sync + ValueInto<f32> + Clamp<f32>,

Warps an image using the provided function to define the pre-image of each output pixel.

Examples

Applying a wave pattern.

use image::{ImageBuffer, Luma};
use imageproc::utils::gray_bench_image;
use imageproc::geometric_transformations::*;

let image = gray_bench_image(300, 300);
let warped = warp_with(
    &image,
    |x, y| (x, y + (x / 30.0).sin()),
    Interpolation::Nearest,
    Luma([0u8])
);
