Please help me to iterate through the layers and find their colors

Dear experts

I have attached a PSD herewith.

I want to iterate through the layers and find the colors of them.

The layers can be either SOLID FILL layers or NORMAL layers which are rasterized from the COLOR FILL layers. So they have only one color, that is a known factor. Moreover the layers can be like a border, the inside part can be transparent, like layer 4.

Getting the colors from the SOLID FILL layers is very easy, but for NORMAL layers we need to check the average color or the most prominent color.

We have the code for picking up the most prominent color from a document from my earlier post -
https://community.adobe.com/t5/photoshop-ecosystem-discussions/adobe-script-selecting-the-most-prominent-color-from-a-psd-layer/m-p/14056020#M751617

 

But the above mentioned code is for picking up the most prominent color from the whole document, and not from a layer. Hence I am not able to use this code for my purpose. I have spent a lot of time to modify the above code for my purpose, it is now looping through all the layers, but it's a nasty code; it needs a lot of modification. But since it's AM code, it's beyound my knowledge 🙂 Also it's not working properly. For the 4th layer, it is showing that the most prominent color is the white, because it's flattening the layers. So I need to delete the background layer. Then it would give me the most prominent color. I tried to delete the background layers, but I am not able to. How can I delete the background layer from the temp file colors.raw??? My code -

const DE_THRESHOLD = 15, RESIZE_TO = 35;

for (var x=0; x<app.activeDocument.layerSets.length; x++) {
    var layerSet = app.activeDocument.layerSets[x];
    if (layerSet.name=="Images" || layerSet.name=="Images_1" || layerSet.name=="Images_2") {
        for (var layerIndex = 0; layerIndex < layerSet.layers.length; layerIndex++) {
            var layer = layerSet.layers[layerIndex];
            app.activeDocument.activeLayer = layer;
            var bounds = layer.bounds;
            var width = bounds[2].value - bounds[0].value;
            var height = bounds[3].value - bounds[1].value;
            app.documents.add( width, height, 300, "temp",NewDocumentMode.RGB, DocumentFill.WHITE,1.0, BitsPerChannelType.EIGHT, "Adobe RGB (1998)" );

So can you please modify this code so that it can currectly pickup the colors in all the cases?

Thanks in advance...

Correct answer c.pfaffenbichler

 

 

app.activeDocument = app.documents[0];

 

 

seems like a problematic way to address an image. 

How do you know documents[0] is the relevant open image? 

 

Your primary complaint (»for each layer I am duplicating the layer into a new document and processing the same logic that is applicable for a whole document«) seems a bit strange to me – if you want to get the values for each Layer then what else do you expect to do than process each Layer individually? 

 

And it still seems somewhat unclear what you are doing with this Script – you are setting the Foreground Color repeatedly so what is the point? 

I inserted an alert but otherwise this might run slightly faster. (updated the code 2023-09-08)

Hi

I have now corrected the code, it's now processing each layer and correctly determining the layer color.

But as you can see, for each layer I am duplicating the layer into a new document and processing the same logic that is applicable for a whole document. So this is not a very good piece of code!

Can we do it in a nicer way?

app.activeDocument = app.documents[0];

 

 

seems like a problematic way to address an image. 

How do you know documents[0] is the relevant open image? 

 

Your primary complaint (»for each layer I am duplicating the layer into a new document and processing the same logic that is applicable for a whole document«) seems a bit strange to me – if you want to get the values for each Layer then what else do you expect to do than process each Layer individually? 

 

And it still seems somewhat unclear what you are doing with this Script – you are setting the Foreground Color repeatedly so what is the point? 

I inserted an alert but otherwise this might run slightly faster. (updated the code 2023-09-08)

    Hi @c.pfaffenbichler 

    Thanks a lot for your generous help, much thankful!

    My program logic is that I need to check the colors of each layer, and if they are not white or grey or black i.e. if the red, green and blue values are not the same, then change their colors. Hence I need to check the colors of all the layers in a loop.

    I have check many sample codes posted in this forum with the following lines -

    var apl = new AM('application'),
doc = new AM('document'),
lr = new AM('layer'),

    For example, this one -
    Solved: Re: Script that updates (Copy/Paste) masks on mul... - Adobe Support Community - 12313689


    So I was thinking instead of duplicating each layer as a new document, if we can directly process each layer without creating a new document, the code would run much faster. So our processEachLayer() function should be changed. But anyway, since this code is working fine, I finally gave up after trying for three days!

     

    Thanks again for your time and eagerness to solve this issue. I am really really thankful!

    Have a nice day.
