//! Traits for converting between color spaces. //! //! # Deriving //! //! `FromColorUnclamped` can be derived in a mostly automatic way. //! The default minimum requirement is to implement `FromColorUnclamped<Xyz>`, but it can //! also be customized to make use of generics and have other manual implementations. //! //! It is also recommended to derive or implement [`WithAlpha`](crate::WithAlpha), //! to be able to convert between all `Alpha` wrapped color types. //! //! ## Configuration Attributes //! //! The derives can be configured using one or more `#[palette(...)]` attributes. //! They can be attached to either the item itself, or to the fields. //! //! ``` //! # use palette::rgb::{RgbStandard, RgbSpace}; //! # use palette::convert::FromColorUnclamped; //! # use palette::{Xyz, Component, FloatComponent}; //! # //! #[palette( //! component = "T", //! rgb_standard = "S", //! white_point = "<S::Space as RgbSpace>::WhitePoint", //! )] //! #[derive(FromColorUnclamped)] //! #[repr(C)] //! struct ExampleType<S: RgbStandard, T: Component> { //! // ... //! #[palette(alpha)] //! alpha: T, //! standard: std::marker::PhantomData<S>, //! } //! //! # impl<S, T> FromColorUnclamped<Xyz<<S::Space as RgbSpace>::WhitePoint, T>> for ExampleType<S, T> //! # where //! # S: RgbStandard, //! # T: FloatComponent //! # { //! # fn from_color_unclamped(color: Xyz<<S::Space as RgbSpace>::WhitePoint, T>) -> Self { //! # ExampleType {alpha: T::max_intensity(), standard: std::marker::PhantomData} //! # } //! # } //! # //! # impl<S, T> FromColorUnclamped<ExampleType<S, T>> for Xyz<<S::Space as RgbSpace>::WhitePoint, T> //! # where //! # S: RgbStandard, //! # T: FloatComponent //! # { //! # fn from_color_unclamped(color: ExampleType<S, T>) -> Self { //! # Xyz::default() //! # } //! # } //! ``` //! //! ### Item Attributes //! //! * `skip_derives(Luma, Rgb)`: No conversion derives will be implemented for these colors. //! They are instead to be implemented manually, and serve as the basis for the automatic //! implementations. //! //! * `white_point = "some::white_point::Type"`: Sets the white //! point type that should be used when deriving. The default is `D65`, but it //! may be any other type, including type parameters. //! //! * `component = "some::component::Type"`: Sets the color //! component type that should be used when deriving. The default is `f32`, but //! it may be any other type, including type parameters. //! //! * `rgb_standard = "some::rgb_standard::Type"`: Sets the RGB standard //! type that should be used when deriving. The default is to either use `Srgb` //! or a best effort to convert between standards, but sometimes it has to be set //! to a specific type. This also accepts type parameters. //! //! ## Field Attributes //! //! * `alpha`: Specifies field as the color's transparency value. //! //! ## Examples //! //! Minimum requirements implementation: //! //! ```rust //! use palette::convert::FromColorUnclamped; //! use palette::{Srgb, Xyz, IntoColor}; //! //! /// A custom version of Xyz that stores integer values from 0 to 100. //! #[derive(PartialEq, Debug, FromColorUnclamped)] //! struct Xyz100 { //! x: u8, //! y: u8, //! z: u8, //! } //! //! // We have to implement at least one "manual" conversion. The default //! // is to and from `Xyz`, but it can be customized with `skip_derives(...)`. //! impl FromColorUnclamped<Xyz> for Xyz100 { //! fn from_color_unclamped(color: Xyz) -> Xyz100 { //! Xyz100 { //! x: (color.x * 100.0) as u8, //! y: (color.y * 100.0) as u8, //! z: (color.z * 100.0) as u8, //! } //! } //! } //! //! impl FromColorUnclamped<Xyz100> for Xyz { //! fn from_color_unclamped(color: Xyz100) -> Xyz { //!
