Reading Hex Codes on each layer of a Photoshop Document?

I have this script (modified a bit) from @jazz-y  that allows me to read all the hex codes in a document into an array which is great. I was wondering if there was a way to push the hexes into their own arrays based off the layers?

 

 

const DE_CIE76 = 0; //color difference: 0-255
const THRESHOLD = 0; //color pixels threshold

var s2t = stringIDToTypeID,
    t2s = typeIDToStringID,
    colorsObj = {},
    colorsArr = [];
(r = new ActionReference()).putProperty(s2t('property'), p = s2t('mode'));
r.putEnumerated(s2t('document'), s2t('ordinal'), s2t('targetEnum'));
if (t2s(executeActionGet(r).getEnumerationValue(p)) == 'RGBColor') {
    var f = new File(Folder.temp + '/colors.raw');
    (d = new ActionDescriptor()).putBoolean(s2t("channelsInterleaved"), true);
    d.putBoolean(s2t('copy'), true);
    (d1 = new ActionDescriptor()).putObject(s2t("as"), s2t("rawFormat"), d);
    d1.putPath(s2t("in"), f);
    executeAction(s2t("save"), d1, DialogModes.NO);
    f.open('r');
    f.encoding = "BINARY";
    doForcedProgress('Reading colors', 'readColors(f.read(), colorsObj)');
    f.close();
    f.remove();
    for (var a in colorsObj) if (colorsObj[a] > THRESHOLD) colorsArr.push({hex: a });
    if (DE_CIE76) doForcedProgress('Filtering colors by dE = ' + DE_CIE76, 'filterByDE(colorsArr)');
}
        
function readColors(s, colorsObj) {
    for (var i = 0; i < s.length; i += 3) {
        var cur = toHex(s, i, 3)
        updateProgress(i, s.length)
        if (colorsObj[cur]) colorsObj[cur]++; else colorsObj[cur] = 1;
    }
}
function filterByDE(c) {
    for (var i = 0; i < c.length; i++) {
        updateProgress(i, c.length)
        if (c[i] == null) continue;
        var cA = new SolidColor;
        cA.rgb.hexValue = c[i].hex;
        for (var x = i + 1; x < c.length; x++) {
            if (c[x] == null || c[i] == null) continue;
            var cB = new SolidColor;
            cB.rgb.hexValue = c[x].hex;
            if (deltaE(cA, cB) <= 10) {
                if (c[i].pixels > c[x].pixels) {
                    c[i].pixels += c[x].pixels
                    c[x] = null
                } else {
                    c[x].pixels += c[i].pixels
                    c[i] = null
                }
            }
        }
    }
}
function toHex(s, from, bits) {
    var h = '';
    for (var i = from; i < from + bits; i++) h += (('0' + s.charCodeAt(i).toString(16)).slice(-2));
    return h
}
function deltaE(a, b) {
    return Math.sqrt(Math.pow(b.lab.l - a.lab.l, 2) + Math.pow(b.lab.a - a.lab.a, 2) + Math.pow(b.lab.b - a.lab.b, 2))
}

 

Here is my example document:

Zee333_1-1690396026552.png

 

In this example I have four layers named Corgi, Tennis Racquet, Runner, and Bowling Ball and Pin as well as a background layer. The current code generates a list of hex codes which I put in a note. I can shift the background color into it's own array so that my note reads

"Background: Hex1

Hex2

Hex3

Hex4

etc."

But what I really want is a note like this:

"Background: Hex1

Layer 1

Hex2

Hex3

Layer 2

Hex2

Hex4

etc."

I understand that in this code to read the colors a temporary raw file is made and read, ignoring all the layers. Is there a way to read the colors layer by layer or somehow sort the colors after the colors are read?

I really appreciate any help anyone can offer!

You can hide all and show each Layer in turn and run the opration once per Layer.

As far as I can tell the Raw has no transparency, so a background would be introduced and change the quantity of the white pixels.

Thanks, @r-bin ! 

 

Then the OP should be able to run the operation on each Layer in turn and get meaningul quantities.

I think I could add the property the way 

d.putBoolean(s2t("channelsInterleaved"), true); is scripted but I can't find the magic words

ok thanks I figured it out!

Zee333_1-1709136008022.png

 

Unfortunately it didn't stop white being pushed to all layers and came with a host of weird values

Zee333_0-1709135975318.png

so I guess I'm back to leaving transparency off and figuring out why white is being auto pushed to each layer's array.

Thanks for helping me fing it though!

I doubt I will be able to solve the problem, but could you post the code you are using at current?

Could you use a »greenscreen«, a color that will never be used in the illustration, for a background and remove that from the results?

Unfortunately I'm still pretty new at scripting so not yet, I am trying though. I have a script that hides all layers and shows them one at a time but I'm having trouble getting the color reading to work in the context of a plugin or my layer cycling script to work outside the context of a plugin (I don't understand how the color reading code works very well)

const app = require("photoshop").app;
const activeLayers = app.activeDocument.activeLayers;

function circulateLayers() {
    activeLayers.visible = false
//sets all selected layers to hidden
    activeLayers.forEach(layer => {
  //shows one layer at a time
      layer.visible = true; 
  
     //Needs to read document colors and push them into an array named after the layer
     const DE_CIE76 = 0; //color difference: 0-255
     const THRESHOLD = 0; //color pixels threshold
//Modified Color Reading Code

        var s2t = stringIDToTypeID,
            t2s = typeIDToStringID,
            colorsObj = {},
            colorsArr = [],
            tempArr = [];
        (r = new ActionReference()).putProperty(s2t('property'), p = s2t('mode'));
        r.putEnumerated(s2t('document'), s2t('ordinal'), s2t('targetEnum'));
        if (t2s(executeActionGet(r).getEnumerationValue(p)) == 'RGBColor') {
            var f = new File(Folder.temp + '/colors.raw');
            (d = new ActionDescriptor()).putBoolean(s2t("channelsInterleaved"), true);
            d.putBoolean(s2t('copy'), true);
            (d1 = new ActionDescriptor()).putObject(s2t("as"), s2t("rawFormat"), d);
            d1.putPath(s2t("in"), f);
            executeAction(s2t("save"), d1, DialogModes.NO);
            f.open('r');
            f.encoding = "BINARY";
            doForcedProgress('Reading colors', 'readColors(f.read(), colorsObj)');
            f.close();
            f.remove();
            for (var a in colorsObj) if (colorsObj[a] > THRESHOLD) tempArr.push({hex: a });
            if (DE_CIE76) doForcedProgress('Filtering colors by dE = ' + DE_CIE76, 'filterByDE(colorsArr)');
            }
            colorsArr.concat(tempArr);
     
    layer.visible = false; 
    console.log("Here I Go!") 
})
console.log(activeLayers.length)
     activeLayers.forEach(layer => {
      layer.visible = true; 
      console.log("Here I Am Again!") 
     })
 
    }

    function readColors(s, colorsObj) {
      for (var i = 0; i < s.length; i += 3) {
          var cur = toHex(s, i, 3)
          updateProgress(i, s.length)
          if (colorsObj[cur]) colorsObj[cur]++; else colorsObj[cur] = 1;
      }
    }
    function toHex(s, from, bits) {
      var hex = '';
      for (var i = from; i < from + bits; i++) h += (('0' + s.charCodeAt(i).toString(16)).slice(-2));

 Here is what I have so far. Right now, it stops at  

activeLayers.forEach(layer => { because the code I wrote for this I wrote in a plugin and it doesn't work when I just run it as a script. Any documentation on how scripting for photoshop differs as straight script vs script in a plugin would be helpful to me. I know it's messy and incomplete but that's where I'm at, thanks for checking in!
