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.

Use apply_orientation if you want to flip the image in-place instead.

pub fn rotate270(&self) -> DynamicImage

Rotate this image 270 degrees clockwise.

pub fn apply_orientation(&mut self, orientation: Orientation)

Rotates and/or flips the image as indicated by Orientation.

This can be used to apply Exif orientation to an image, e.g. to correctly display a photo taken by a smartphone camera:

use image::{DynamicImage, ImageReader, ImageDecoder};

let mut decoder = ImageReader::open("file.jpg")?.into_decoder()?;
let orientation = decoder.orientation()?;
let mut image = DynamicImage::from_decoder(decoder)?;
image.apply_orientation(orientation);

Note that for some orientations cannot be efficiently applied in-place. In that case this function will make a copy of the image internally.

If this matters to you, please see the documentation on the variants of Orientation to learn which orientations can and cannot be applied without copying.

pub fn write_to<W>( &self, w: &mut W, format: ImageFormat ) -> Result<(), ImageError>
where W: Write + Seek,

Encode this image and write it to w.

Assumes the writer is buffered. In most cases, you should wrap your writer in a BufWriter for best performance.

Encode this image with the provided encoder.

pub fn save<Q>(&self, path: Q) -> Result<(), ImageError>
where Q: AsRef<Path>,

Saves the buffer to a file at the specified path in the specified format.
