Is there any way to retrieve angle and scale information of smart object?

I need to retrieve scale and rotation information changes of a smart object in a video animation using a script.

How can I do this?

Correct answer r-bin

on CC2018 it works, on CS6 do not.

function get_smart_object_corners() returns array from 4 corner-points (x,y) of smart object in pixels (value with floating point)

you can caclulate angle and vertical or horisontal dimentions.

))

Code example:

////////////////////////////////////////////////////////////////////////////////////////////

var points = get_smart_object_corners();

var w = points[0][0] - points[1][0];

var h = points[0][1] - points[1][1];

var angle = Math.atan(h/w) * 180.0 / Math.PI;

alert ("Angle is " + angle.toFixed(3) + "°");

////////////////////////////////////////////////////////////////////////////////////////////

function get_smart_object_corners()

    {

    try

        {

        var r = new ActionReference();

        r.putEnumerated( charIDToTypeID( "Lyr " ), charIDToTypeID( "Ordn" ), charIDToTypeID( "Trgt" ) );

        var d;

        try { d = executeActionGet(r); } catch (e) { alert(e); return; }

        try { d = d.getObjectValue(stringIDToTypeID("smartObjectMore"));    } catch (e) { alert(e); return; }

        try { d = d.getList(stringIDToTypeID("transform"));                 } catch (e) { alert(e); return; }

        var ret = [[d.getDouble(0),d.getDouble(1)],

                   [d.getDouble(2),d.getDouble(3)],

                   [d.getDouble(4),d.getDouble(5)],

                   [d.getDouble(6),d.getDouble(7)]];

        return ret;

        }

    catch (e) { alert(e); }

    }

Hi.. check my script "Undeform" Magic scripts for Photoshop

I solved reading most of deformations. Btw rotation and skew are similar. You can rotate object if you apply 2x skew. If you find the way how to solve perspective, please let me know.

      Thanks for the solve! Out of curiosity, are you able to record "smartObjectMore" with scripting listener? Just wondering where this info is stored and how it was found.

        What do you mean by »record« exactly? 

        It is certainly possible to get the values from an existing Smart Object. 

        // based on code by michael l hale;
// 2024, use it at your own risk;
if (app.documents.length > 0) {
var ref = new ActionReference();
ref.putEnumerated( charIDToTypeID("Lyr "), charIDToTypeID("Ordn"), charIDToTypeID("Trgt") ); 
var layerDesc = executeActionGet(ref);
var soDesc = layerDesc.getObjectValue(stringIDToTypeID('smartObject'));
var soMoreDesc = layerDesc.getObjectValue(stringIDToTypeID('smartObjectMore'));
var transform = soMoreDesc.getList(stringIDToTypeID("transform"));
checkDesc2(soMoreDesc)
};
////// based on code by michael l hale //////
function checkDesc2 (theDesc) {
var c = theDesc.count;
var str = '';
for(var i=0;i<c;i++){ //enumerate descriptor's keys
	str = str + 'Key '+i+' = '+typeIDToStringID(theDesc.getKey(i))+': '+theDesc.getType(theDesc.getKey(i))+'\n'+getValues (theDesc, i)+'\n';
	};
alert("desc\n\n"+str);
};
////// check //////
function getValues (theDesc, theNumber) {
switch (theDesc.getType(theDesc.getKey(theNumber))) {
case DescValueType.ALIASTYPE:
return theDesc.getPath(theDesc.getKey(theNumber));
break;
case DescValueType.BOOLEANTYPE:
return theDesc.getBoolean(theDesc.getKey(theNumber));
break;
case DescValueType.CLASSTYPE:
return theDesc.getClass(theDesc.getKey(theNumber));
break;
case DescValueType.DOUBLETYPE:
return theDesc.getDouble(theDesc.getKey(theNumber));
break;
case DescValueType.ENUMERATEDTYPE:
return (typeIDToStringID(theDesc.getEnumerationValue(theDesc.getKey(theNumber)))+"_"+typeIDToStringID(theDesc.getEnumerationType(theDesc.getKey(theNumber))));
break;
case DescValueType.INTEGERTYPE:
return theDesc.getInteger(theDesc.getKey(theNumber));
break;
case DescValueType.LISTTYPE:
return theDesc.getList(theDesc.getKey(theNumber));
break;
case DescValueType.OBJECTTYPE:
return (theDesc.getObjectValue(theDesc.getKey(theNumber))+"_"+typeIDToStringID(theDesc.getObjectType(theDesc.getKey(theNumber))));
break;
case DescValueType.REFERENCETYPE:
return theDesc.getReference(theDesc.getKey(theNumber));
break;
case DescValueType.STRINGTYPE:
return theDesc.getString(theDesc.getKey(theNumber));
break;

        Record/log through scripting listener. Sorry, I meant to specify that. I'm trying to understand how you'd find that through AM, if undocumented and not logged/recorded. It seems to only be informational, so photoshop doesn't find it necessary to place in an AM script.

        Hi

        I've moved your post to the Photoshop Scripting forum where you are more likely to get an answer to your question

          I do not believe it is possible the get the smart Object layer associated transform settings with a Photoshop Script.   You can see the values in Photoshop Tool Option Bar when you Place in an image or you target a smart object layer and use Ctrl+T free transform.  The tool option bar will display the smart object layers current transform settings.
