problem with look up table

Post by svumme »

I am trying to import some lut (color look up) through scripts, but for now without success.
I tried to examine the listener and realized that the code for the lut is split into two blocks of charcode.
I can't post all the lut code because it is very long,
however place a piece of the first block below.
/------------------------------------------------------------------------------------------------------------------
var idcolorLookup = stringIDToTypeID( "colorLookup" );
var desc17 = new ActionDescriptor();
var idlookupType = stringIDToTypeID( "lookupType" );
var idcolorLookupType = stringIDToTypeID( "colorLookupType" );
var idthreeDLUT = stringIDToTypeID( "3DLUT" );
desc17.putEnumerated( idlookupType, idcolorLookupType, idthreeDLUT );
var idNm = charIDToTypeID( "Nm " );
desc17.putString( idNm, """C:\Users\svumme\Downloads\lut\lut1.CUBE""" );
var idDthr = charIDToTypeID( "Dthr" );
desc17.putBoolean( idDthr, true );
var idprofile = stringIDToTypeID( "profile" );
desc17.putData( idprofile, String.fromCharCode( 0, 3, 2, 212, 65, 68, 66, 69, 4, 0, 0, 0, 108, 105, 110, 107, 82, 71, 66, 32, 82, 71, 66, 32, 7, 228, 0, 9, 0, 9, 0, 16,

etc etc

converting the first block into charcode I get special characters.Image
while the second block gives me the lut code therefore it is easily understood.

is there anyone who has already had experience with color lookups and can you help me? I would like to be able to generate lut from my panel (and on this I think I can) but then send them as a layer in photoshop (this is my problem)

Bonjour

I am French and I do not know what this "read"
I have often used this function offeryte par Mike Hale- viewtopic.php?p=41984#p41984 :

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 I appreciate the results rgb or hexvalue ......

thanks for the answer, but unfortunately what I'm trying to do is another thing.
I would like to import Lut (look up table). https://www.photoshopessentials.com/pho ... ain%20look.
