Expand description

A Dynamic Image

This represents a matrix of pixels which are convertible from and to an RGBA representation. More variants that adhere to these principles may get added in the future, in particular to cover other combinations typically used.

§Usage

This type can act as a converter between specific ImageBuffer instances.

use image::{DynamicImage, GrayImage, RgbImage};

let rgb: RgbImage = RgbImage::new(10, 10);
let luma: GrayImage = DynamicImage::ImageRgb8(rgb).into_luma8();

§Design

There is no goal to provide an all-encompassing type with all possible memory layouts. This would hardly be feasible as a simple enum, due to the sheer number of combinations of channel kinds, channel order, and bit depth. Rather, this type provides an opinionated selection with normalized channel order which can store common pixel values without loss.

Variants (Non-exhaustive)§

This enum is marked as non-exhaustive

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.
