Coloris (beta)

go get bitbucket.org/briiC/coloris

Process image to get most used colors.
And return color names that are closest to original colors.
By default skips Black, White and true Gray (#808080) color.

Can be used different color palettes for final color list:

• Palette_ColorNames3
• Palette_ColorNames12 – default
• Palette_ColorNames26
• Palette_ColorNamesMAX – very slow for now

Example

#!go

    // Collect colors
    clist := coloris.AllColors("path/to/image.jpg", nil)

    // Print color info
    for _, c := range clist {
        // c.Name       - closest color name
        // c.NameHex    - closest color hex code
        // c.Count      - color pixel count
        // c.Percents   - color usage in image

        fmt.Println(c.Name, c.Percents) // Blue 20%

    }

Also can use these functions

#!go

    // Get only top 3 colors
    clist := coloris.TopColors("path/to/image.jpg", 3, nil)

    // Get 3 least used colors
    clist := coloris.TopColors("path/to/image.jpg", -3, nil)

    // ONE most used color
    clr := coloris.DominantColor("path/to/image.jpg", nil)

Bugs & TODO’s

• Using Palette_ColorNamesMAX is too slow
