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

[salithan73779666]

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?

Hi

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

Thanks a lot Dave

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.

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); }

    }

In a video animation how do you tie that to the  timeline where the layer may be be being transformed with rotation,  and how do you get the scaling factors?

[salithan73779666]

Thanks, r-bin.

On CC2017 it works.

On CC2014 and CC2015 it doesn't.

I am looking for a solution Photoshop 2014CC onwards.

You can add a rectangular linked vector mask with zero density to the original layer, not an objectively smart object, with dimensions as  the layer. Then, after any transformation or rotation, you can calculate the angles and dimensions using 4 points of the vector mask.
I'm not sure that it will be convenient for you.

ps. hope you understand my poor english )

The script fails in CC 2014 in followind statement for smartObjectMore does not seem to exist in CC 2014.

d = d.getObjectValue(stringIDToTypeID("smartObjectMore"));

[Jarda Bereza]

smartObjectMore was added in 2015.5

[Sahil28330276lxz8]

Hello, thanks for answer. I just want to know how can we use this inside a loop, iterating through all the layers instead of just Trgt. 

[Sahil28330276lxz8]

I have been looking for a solution to get the rotation of all the layers. This code actually worked but it targets the active layer only. I want to iterate through all the layers and get their rotation angle.  

[Pu28469533tdu3]

angle  is got but how can get scale?  any one know?thanks

[Pu28469533tdu3]

perfect solution!

var smartLayerBounds = getSmartObjectBounds(_layer);//get bound

openSmartObject(_layer);

var smartTargetLayerSourceBounds = getOpenSmartSourceBounds(_layer)

var scale = getScale(smartLayerBounds, smartTargetLayerSourceBounds);

What if the Smart Object has been rotated? 

[wckdtall]

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.

[c.pfaffenbichler]

What do you mean by »record« exactly? 

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

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 //////

var c = theDesc.count;

What do you mean by »record« exactly? 

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.

[c.pfaffenbichler]

You can get that information so I do not understand what the problem is. 

What is the actual scenario in which you need to assess or utilize that information? 

[wckdtall]

I'm just trying to understand how to obtain some of these more obscure items on my own. It can help to understand how to edit code and what it is doing. I don't generally like AM, because it's not intuitive to use, but we're forced to since it has more functionality. AM and Extendscript can be a mystery, even with the documentation people have created.

Doesn't seem like there's a way to obtain it with scripting listener, forums are always a great help though.

[c.pfaffenbichler]

Did you even try the code I posted with a Smart Object selected? 

If you need to get the values from any of those keys you can progress from »smartObjectMore«. 

[Nick Combs]

I found the atan conversion of rad to deg causes 180 to be read as 0. There might also be other complications I haven't discovered yet, but for now this additional line is fixing the issue:

if( points[0][1] > points[1][1] ) angle = ( angle + 180 ) % 360

The idea is to compare the y values of the two corners to detect if it's upside down.

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.
