A Julia package to generate color palettes from images.

## Installation 

To install this package and its dependencies, open the Julia REPL and run 

```julia-repl

julia> ]add ColorQuantization

```

## Examples

To extract a color palette from an image, call `quantize` with a [quantization method][docs-methods] of your choice.

```julia

using ColorQuantization

using TestImages

img = testimage("peppers")

quantize(img, KMeansQuantization(256))  # quantize to 256 colors

quantize(img, UniformQuantization(8))   # quantize to an 8x8x8 grid

```

The generated color schemes can be [viewed in the documentation][docs-getting-started].

## Related packages

[ColorSchemeTools.jl](https://github.com/JuliaGraphics/ColorSchemeTools.jl) provides `extract` to generate weighted colorschemes from images using K-means clustering.
