Trait image::buffer::ConvertBuffer[−][src]

pub trait ConvertBuffer<T> {
    fn convert(&self) -> T;
}

Provides color conversions for whole image buffers.

Required methods

`fn convert(&self) -> T`[src]

Examples

Convert RGB image to gray image.

use image::buffer::ConvertBuffer;
use image::GrayImage;
 
let image_path = "examples/fractal.png";
let image = image::open(&image_path)
    .expect("Open file failed")
    .to_rgba();
 
let gray_image: GrayImage = image.convert();
