The image color library

Overview

The color package implements types for representing colors in the usual color models.

Types

Cmyk = struct (c int, m int, y int, k int)

Represents a fully opaque color in the CMYK color model, with 8 bit for each dimension.

Gray = struct (g int)

Represents a shade of gray in 8-bit gray scale.

Rgba = struct (r int, g int, b int, a int)

Represents a color in the RGBA color model, with 8 bits for each dimension.

Rgb = struct (r int, g int, b int)

Like Rgba, but every color is fully opaque.

Rgba_64 = struct (r int, g int, b int, a int)

Represents a color in the RGBA color model, with 16 bits for each dimension.

Rgb_64 = struct (r int, g int, b int)

Like Rgba_64, but every color is fully opaque.

YCbCr = struct (y int, cb int, cr int)

Representation of a fully opaque 24-bit Y'CbCr color, having 8 bits each for one luma and two chroma components.

Color = abstract Cmyk/Gray/Rgb/Rgba/Rgb_64/Rgba_64/YCbCr

The abstract type containing the various color types, Rgb, Rgba, Cmyk, etc.

Functions

swatch(c Color)

Returns a string consisting of "█" with control codes so that it'll display the given color.
