adding curves adjustment layer with .acv preset

Hi everyone
I've been searching for such script for several hours and found nothing.
here is ScriptingListener output for such task (i have added curves adj layer, clicked "load curves preset" and then opened the .acv file):
Code: Select allvar idMk = charIDToTypeID( "Mk " );
var desc8 = new ActionDescriptor();
var idnull = charIDToTypeID( "null" );
var ref2 = new ActionReference();
var idAdjL = charIDToTypeID( "AdjL" );
ref2.putClass( idAdjL );
desc8.putReference( idnull, ref2 );
var idUsng = charIDToTypeID( "Usng" );
var desc9 = new ActionDescriptor();
var idType = charIDToTypeID( "Type" );
var desc10 = new ActionDescriptor();
var idpresetKind = stringIDToTypeID( "presetKind" );
var idpresetKindType = stringIDToTypeID( "presetKindType" );
var idpresetKindDefault = stringIDToTypeID( "presetKindDefault" );
desc10.putEnumerated( idpresetKind, idpresetKindType, idpresetKindDefault );
var idCrvs = charIDToTypeID( "Crvs" );
desc9.putObject( idType, idCrvs, desc10 );
var idAdjL = charIDToTypeID( "AdjL" );
desc8.putObject( idUsng, idAdjL, desc9 );
executeAction( idMk, desc8, DialogModes.NO );
but running such script only adds curves adjustment layer with no preset

So does anybody know how to load an .acv preset?

Any help would be greatly appreciated.

Please try this (it assumes that a valid curves preset file named test.acv is located on your desktop):
Code: Select allfunction makeCurvesAdjustmentLayerFromAcvFile (acvFilePath)
{
var desc8 = new ActionDescriptor ();
var ref2 = new ActionReference ();
ref2.putClass (stringIDToTypeID ("adjustmentLayer"));
desc8.putReference (stringIDToTypeID ("target"), ref2);
var desc9 = new ActionDescriptor ();
var desc10 = new ActionDescriptor ();
desc10.putEnumerated (stringIDToTypeID ("presetKind"), stringIDToTypeID ("presetKindType"), stringIDToTypeID ("presetKindUserDefined"));
desc10.putPath (stringIDToTypeID ("using"), new File (acvFilePath));
desc9.putObject (stringIDToTypeID ("type"), stringIDToTypeID ("curves"), desc10);
desc8.putObject (stringIDToTypeID ("using"), stringIDToTypeID ("adjustmentLayer"), desc9);
executeAction (stringIDToTypeID ("make"), desc8, DialogModes.NO);
}
makeCurvesAdjustmentLayerFromAcvFile ("~/Desktop/test.acv");

HTH...

Thanks man!!! works like a charm
I can now easily load a bunch of saved curves layers to achieve certain looks.

Can you please suggest me some material/resources to check to be better at managing adjustment layers?
Original photoshop-javascript reference is hard to get information from
I was naive to think that changing "curves" to "huesaturation" and ".acv" to ".ahu" in your function would make the same function for hue/saturation, well, it's not)

It does work, actually, except that the relevant StringID is "hueSaturation" (not "huesaturation").

Please try this (again, it assumes that a valid hue/saturation preset file named test.ahu is located on your desktop):
Code: Select allfunction makeHueSaturationAdjustmentLayerFromAhuFile (ahuFilePath)
{
var desc8 = new ActionDescriptor ();
var ref2 = new ActionReference ();
ref2.putClass (stringIDToTypeID ("adjustmentLayer"));
desc8.putReference (stringIDToTypeID ("target"), ref2);
var desc9 = new ActionDescriptor ();
var desc10 = new ActionDescriptor ();
desc10.putEnumerated (stringIDToTypeID ("presetKind"), stringIDToTypeID ("presetKindType"), stringIDToTypeID ("presetKindUserDefined"));
desc10.putPath (stringIDToTypeID ("using"), new File (ahuFilePath));
desc9.putObject (stringIDToTypeID ("type"), stringIDToTypeID ("hueSaturation"), desc10);
desc8.putObject (stringIDToTypeID ("using"), stringIDToTypeID ("adjustmentLayer"), desc9);
executeAction (stringIDToTypeID ("make"), desc8, DialogModes.NO);
}
makeHueSaturationAdjustmentLayerFromAhuFile ("~/Desktop/test.ahu");

You may want to have a look at my Layer Object Simplified Format, expressed in JSON syntax.

It is mainly used by my script Adjustment & Fill Gallery, which applies on an existing RGB image an effect made of a stack of adjustment layers and fill layers.

Unfortunately, I do realize now that I haven't documented how to handle preset files, except for the hue/saturation adjustment layer. I'll probably do that soon...

HTH...

This is quite interesting stuff!
Thank you for your time and fast reply!
