Paletter

Paletter is a CLI app and library to extract a color palette from an image through clustering (k-Means)

Example output:

Installation

To install paletter just use:

$ go get -u -v github.com/Baldomo/paletter

To install the CLI app use:

$ go install -v github.com/Baldomo/paletter/cmd/paletter

Usage (CLI)

Usage: paletter [OPTIONS] <IMAGE>
Flags:
  -colors int
        Number of colors to extract from the image (default 7)
  -html
        Output an html page
  -out string
        Set output file name/path
  -png
        Output a png image (default true)

The CLI app outputs png images of resolution dependent on the source image (see genimage.go for calculations), with the extracted palette ordered by lightness from left to right

Notes

• Paletter uses the CIE L*a*b* color space both for the simplicity of its representation and it being device-indipendent
• The k-Means implementation included in paletter is the naive one (muesli/kmeans)
