hsvimage and hsvcolor

Go Report Card Go Reference

The Go programming language's standard library provides support for manipulating graphical images represented using RGB, CMYK, YCbCr, and grayscale color models and variations such as 8- vs. 16-bit channels, premultiplied alpha vs. non-premultiplied alpha vs. no alpha, and paletted color. hsvimage augments the Go standard library with support for the HSV (hue, saturation, and value) color model.

Usage

hsvimage provides the following new image types (all of which implement the image.Image interface), color types (all of which implement the color.Color interface, and color models (all of which implement the color.Model interface):

Image Color Color model Description
NHSVA NHSVA NHSVAModel Non-alpha-premultiplied HSV + alpha, 8-bit color channels
NHSVA64 NHSVA64 NHSVA64Model Non-alpha-premultiplied HSV + alpha, 16-bit color channels
NHSVAF64 NHSVAF64 NHSVAF64Model Non-alpha-premultiplied HSV + alpha, 64-bit floating-point color channels

hsvimage and hsvimage/hsvcolor, which are analogous to Go's image and image/color, respectively, can be imported in the usual manner:

import (
	"github.com/spakin/hsvimage"
	"github.com/spakin/hsvimage/hsvcolor"
)

Documentation

See the pkg.go.dev documentation for hsvimage and hsvcolor.
