prismatica 1.0.0

//! Image crate integration.
//!
//! Provides bidirectional conversion between [`Color`](crate::Color)
//! and [`image::Rgb`].
//!
//! # Examples
//!
//! ```ignore
//! use prismatica::crameri::BATLOW;
//!
//! let color = BATLOW.eval(0.5);
//! let pixel: image::Rgb<u8> = color.into();
//! let back: prismatica::Color = pixel.into();
//! assert_eq!(color, back);
//! ```
