How can i detect hi-lights above 250 using JavaScript

[_lmendoza_]

HI everyone

i have an script that deletes alpha channels, paths, layer comps, flat the image, change color mode, set resolution to 300 ppi and so on, but now I need to make a selection or at list detect highlights above 250 in RGB channels and also I need to find a way to change the "color profile" from X profile to "Adobe RGB 1998"

Thanks

Here is some code that might do the job for your highlights..

Hi Paul,

I am looking for a jsx-code to automate the detection of the coordinates of the brightest/darkest pixels in a photoshop file.

Searching the forum I found your answer with a link to ps-scripts.com.

Unfortunately the thread you are referring to is not available any more.

Do you have by chance the code from this thread?

Thanks for any help.

Bonjour

Using the select Color Range function (scrObj)
from Mike Hale :

//Recherche de crame

var blue = new SolidColor();

blue.rgb["hexValue"] =  "ffffff"          // "829fb1"       // "0000ff";

for( var f = 0; f < activeDocument.artLayers.length; f++ ){ activeDocument.activeLayer = activeDocument.artLayers;

   selectColorRange(blue);

function selectColorRange(scObj){

    var desc = new ActionDescriptor();

    desc.putInteger( charIDToTypeID( "Fzns" ), 0 );

        var cDesc = new ActionDescriptor();

        cDesc.putDouble( charIDToTypeID( "Rd  " ), scObj.rgb.red);

        cDesc.putDouble( charIDToTypeID( "Grn " ), scObj.rgb.green);

        cDesc.putDouble( charIDToTypeID( "Bl  " ), scObj.rgb.blue );

    desc.putObject( charIDToTypeID( "Mnm " ), charIDToTypeID( "RGBC" ), cDesc );

    desc.putObject( charIDToTypeID( "Mxm " ), charIDToTypeID( "RGBC" ), cDesc );

   executeAction( charIDToTypeID( "ClrR" ), desc, DialogModes.NO );

}

And what are you going to do with the coordinates of the pixels? There may be a lot of them.

I am just trying to automate photoshop color correction with a curve adjLayer using it's eyedropper tool for white, grey and black values.

To adjust the curves by script I need to know the coordinates of the brightest highlights, 50% grey values and the deepest shadows in the picture.

Manually I would do that using the slider in a threshold adjLayer to detect the brightest resp. darkest values and marking them with the eyedropper tool (I). Jimmy McIntyre has described this procedure in his  "Powerful Color Correction Photoshop Tutorial".

It would be great to do that by script.

I do it with several personal jsx scripts
Under Win 10 and CS5
