Can palette shows up color occurence amount

[frankred]

Is there a possibility to get information about the occurence amount of the final colors? My intention is to sort the palette by occurence amount.

i added an option to disable palette sorting, by default it is ordered by highest to lowest occurrence counts: .palette(tuples, noSort). you can get the palette histogram like this, for example:

var pal = quant.palette(false, true);

var palHist = [];
quant.idxi32.forEach(function(i32) {
    palHist.push({color: quant.i32rgb[i32], count: quant.histogram[i32]});
});

console.log(palHist);

or

// called with no arguments (auto-sorted)
var pal = quant.palette();

var palHist = [];
quant.idxi32.forEach(function(i32) {
    palHist.push({color: quant.i32rgb[i32], count: quant.histogram[i32]});
});

// sort it yourself
palHist.sort(function(a,b) {
    return a.count == b.count ? 0 : a.count < b.count ? 1 : -1;
});

console.log(palHist);

Ah ok I didn't know that the color output palette is ordered. Thank you very much!

Edit: I just want to say that the output is not sorted. Here is an example that is in my code:

[
    {
        "color": [
            255,
            255,
            255
        ],
        "count": 630611
    },
    {
        "color": [
            207,
            201,
            188
        ],
        "count": 1170
    },
    {
        "color": [
            30,
            37,
            63
        ],
        "count": 3
    },
    {
        "color": [
            81,
            98,
            118
        ],
        "count": 95290
    }
]

This isn't ordered... but now I know how to order it, thank you...

[leeoniya]

since last commit, it should be ordered by counts if you disable sorting by using quant.palette(false, true) instead of quant.palette()

it will still sort by default if you did not change the way the palette generation is called.

Ok thank you!

[leeoniya]

in your case it may be quant.palette(true, true), if you're wanting ordered tuples.
