Expand description

A Dynamic Image

This represents amatrix ofpixels which areconvertible from and to anRGBArepresentation. More variants that adhere to these principles may get added in the future, inparticular to cover other combinations typically used.

§Usage

This type can act as a converter between specificImageBuffer instances.

useimage::{DynamicImage, GrayImage, RgbImage};letrgb: RgbImage = RgbImage::new(10,10);letluma: GrayImage = DynamicImage::ImageRgb8(rgb).into_luma8();

§Design

There is no goal to provide an all-encompassing type with all possible memory layouts. Thiswould hardly be feasible as a simple enum, due to the sheer number of combinations of channelkinds, channel order, and bit depth. Rather, this type provides an opinionated selection withnormalized 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.

useimage::{DynamicImage, ImageReader, ImageDecoder};letmutdecoder = ImageReader::open("file.jpg")?.into_decoder()?;letorientation = decoder.orientation()?;letmutimage = 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.

Encode this image with the provided encoder.

Source

pub fnsave<Q>(&self, path: Q) ->ImageResult<()>
