How can I retrieve the transform information on a layer

I am trying to retrieve the transformation information on a layer through script (for a smart object if it matters).

I've been able to do it if there is a text layer attached, but I need to be able to do it with just the smart object.

This is what I have so far:

var idnull = charIDToTypeID("null");
var layerReference = new ActionReference();
layerReference.putEnumerated(charIDToTypeID("Lyr "), charIDToTypeID("Ordn"), charIDToTypeID("Trgt"));
var layerDescriptor = new ActionDescriptor();
layerDescriptor.putReference(idnull, layerReference);
layerDescriptor.putEnumerated(charIDToTypeID("FTcs"), charIDToTypeID("QCSt"), charIDToTypeID("Qcsa"));
var transformDescriptor = app.executeAction(charIDToTypeID("Trnf"), layerDescriptor, DialogModes.NO);
var offset= transformDescriptor.getObjectValue(charIDToTypeID("Ofst"));
var horizontalOffset = offset.getUnitDoubleValue(charIDToTypeID("Hrzn"));
var verticalOffset = offset.getUnitDoubleValue(charIDToTypeID("Vrtc"));

However, horizontalOffset and verticalOffset are both returned as zero.

Thanks in advance, Mark.

I'd really just like to pull out the existing transformations applied to the layer.

I’m confident that information is not stored with the Layer, not even with a Smart Object, because the Layer’s position at some previous time is generally irrelevant.

Rotation, Scale, Skew, … are different for a Smart Object naturally – unfortunately they can not be directly retrieved as fas as I know.

And Type Layers are special cases anyhow.

However, if I open the free transform tool on the smart object, the current transformations (e.g., x, y, rotational angle, scale, etc) are all available, so they must be stored somewhere associated with that smart object.

Basically I need to replace the smart object with the layers in the smart object and transform them in such a way that they match the transformations applied to the smart object. I want to actually extract the layers, and not just edit the linked SO.

if I open the free transform tool on the smart object, the current transformations (e.g., x, y, rotational angle, scale, etc)

But x and y are not related to the offset of a previous transformation, but the current position.

And as I already mentioned this information is not Script-accessible to the best of my knowledge (and others have tried, too).

I think you are going about this less than ideally, especially as Warps, perspectival transformations etc. might be difficult to evaluate.

One can use "New Smart Object via Copy" instead, open the SO and hide all but one Layer, save, rasterize, repeat for the next Layer etc.

I even attempted a Script on that basis once, but Groups, Layer Masks on Groups and Adjustment Layers, Clipping Masks etc. proved a bit difficult to handle …

in any case, it seems its worth pointing out that once scaled, bitmap pixels are gone - so rescaling back to the original size is not loss-less

thanks

Well examples show using a smartObject, not even sure what you mean by "Bitmap pixels are gone"???

from cc 2015, we can get 4 points coordinates of smartobject layer

1. then we can calculate the angle

2. we can calculate the size of current smartobject layer, we can also get the original size of smartobject by action manager, so "current size/original size" is the scale

There are problem with that script's function getSmartObjectScale getgetSmartObjectScaleSmartObjectScale getSmartObjectScale getSmartObjectScale.

function getSmartObjectScale (layer) {
    if (layer.kind != LayerKind.SMARTOBJECT) {alert("layer is not smart object!"); return null;}
     var originalActiveLayer = app.activeDocument.activeLayer;
     app.activeDocument.activeLayer = layer;
     //获取智能对象当前尺寸
     var originalSize = getSmartObjectSize (layer);
    //进入智能对象编辑页面，获取智能对象原尺寸
    var idplacedLayerEditContents = stringIDToTypeID( "placedLayerEditContents" );
    var desc1900 = new ActionDescriptor();
    executeAction( idplacedLayerEditContents, desc1900, DialogModes.NO );//进入对象编辑页面
    //获取文档大小
    var width = app.activeDocument.width.value;
    var height = app.activeDocument.height.value;
    app.activeDocument.close (SaveOptions.DONOTSAVECHANGES);
    app.activeDocument.activeLayer = originalActiveLayer;
    
    return {"width": originalSize.width/width, "height": originalSize.height/height};
}

All smart object layers are not the same. There are different type of objects. That script function opens the active layer object "placedLayerEditContents" that is a problem. All object will not be opened by Photoshop. A placed image file may not open in Photoshop. My test document had a Placed RAW file when the script function open the object I was then in ACR when I click OK the function closed the current document in Photoshop and there was no open Document in Photoshop. Likewise with a vector smart object layer a placed .svg file the SVG was opend in Internet Eplorer on my machine and when I closed IE the function close the current document and nothing was open in Photoshop.

When my smart object layer was a placed Jpeg file the function getSmartObjectScale would only get the scale correct when the Documents DPI and the Jpeg same the same DPI.

I added thie alert to your script so you can see the scale isn not correct.

alert("scale " + scale.width + " " + scale.height + "\n"

+ "size " + size.width + " " + size.height + "\n"

+ "corners " + corners + "\n"

+ "bounds " + bounds + "\n"

+ "angle " + angle);

Here is a screen capture shows the Placed jpeg place transform in the tool option bar then I ran your script and then an other script like your that rounds values gets the scaling right and it works with all object types for it does not open the objects. Vector Smart Opbects have not size. Devision by 0 is infinity so theat script shows infinity as yje scale value not what the Place transfom shows. Photoshop must set some size for Places .svg and .ai files. I was unable to figure out how Photoshop handled placed vector files like .svg and .ai files.

A Placed SVG file Follows

Thanks for your reply!

PS can not open svg smart object layer. But we can export the original svg file by action manager. Then open it again by ps. So we can get its size.

var idplacedLayerExportContents = stringIDToTypeID( "placedLayerExportContents" );

var desc3027 = new ActionDescriptor();

var idnull = charIDToTypeID( "null" );

desc3027.putPath( idnull, new File( "/Users/admin/xxx.svg" ) );

executeAction( idplacedLayerExportContents, desc3027, DialogModes.NO );

Have you been able to do it? Using what r-bin posted for a smart object layer if it is rectangular you should be able to get the object's width and height scaling and angle of rotation, If it been distorted with some perspective or warp I think it very hard or impossible to deal with. Even it is rectangular I do not know if it would be easy to determine if it has been flipped vertically or horizontally.

Photoshop also does some scaling when the object resolution is not the same as the document resolution. I have been able to figured exactly what Photoshop does whet there is a resolution mismatch. After I place in image in a script I always the smart object layers associated transform to 100% width and height. so I know the object size using layer bounds. and know it the object is it full size and work from there. I know I can resized it the way I need to then.

By look at the four corners x y in order you can tell if the layer has been flipped. However the layer can be flipped horizontally or vertically also be rotated and the object and documents can have different resolutions. Telling what is what is complex.

Here an Smart Object image layer with no rotation straight up portrait and not flipped, then flipped horizontally, then flipped vertically, and then flipped horizontally and vertically. Screen Capture shows the Smart object layers Transform setting in the tool option bar. Also screen captures that show Information a script can retrieved using the action manager code r-bin posted for retrieving the objects dour corners and some of the additional smart object information available. By comparing the x,y corner points positions relative to each other in order one would be able to figure out if any flipping was done. However as shown in my previous append throwing in rotation may make it much harder rotation 90, 180, 270 may look like flipping or 180 may look lo 0 and 270 look like 90.

Hi. Have read many threads about this. But haven't find any solution. So do you have any luck with your issue?

I have a smartObject which is flipped horizontally. And I need get a current width value. If it have "-" smartObject is flipped.

Can anyone help me with this?

Thanks in advance.

If you are using CC 2018, r-bin posted some action manager code the can get the four corners of your smart object layer. For me he also posted more code about other smart object information can be retrieved. You may want to search for those threads. I just hack at javascript I do not know it.

From the four corners you can determine if the Object has been rotated or not. You can get the length of the sides and the slopes of the side to see it the are parallel and see if they form a rectangle. Some of the information about the information retrieved about the Smart included it actual size. So you may be able to calculate and scaling done if the smart object is still a rectangle. I did not go ther far.

Here is a hack I did using his code. It will give you the four side and their slopes. The script only used his code for the objects four corners the other code he posted is not in this hack.

Oh man, I know your frustration.
I'm having the similar woes. However, I'm not looking to apply the information to another layer, but just read the data, for use in other ways.
I also, didnt expect to run into this problem, as when CTRL+T is used on a smart object, the relative scale and angle are visible in the "INFO" window. I figured it was an easy win to get the transforms. I was wrong.
I find myself lost in TypeID's and unclear class structures for smartObjects. I just havent found any good reference for "getting" the property value, only ways of setting it, sadly.

If you or anyone else are successful, I'd be very interested in a solution also, likewise, if I stumble into it, I'll post it.

I've made a script that somehow took the informations from the Smart Layer's transforms,

you can check this post: Need help cleaning up a script and adding loop, there is a reply there explaining what the script is doing, till now is the only way I found to get these values without reading the binary of the psd.

thanx it worked for me!!

Under which circumstances exactly does this provide the result you intend (what does "attached text layer" mean)? Could you post a screenshot with the Layers Panel visible?

Once a Layer has been moved that information may be in the History but as far as I can tell no space is wasted on storing that information with the Layer itself.

Sorry, here's some clarification. If I use code found here How to extract layer rotation (transform) in jsx photoshop script? - Stack Overflow for retrieving the transform of the text layer "PixelSquid Diving Helmet" it will work. What I'm trying to do is get the transform that's applied to the layer DivingHelmet.H03, basically the data that is available:

I'd like the information on the existing transformations applied to the object, not trying to apply a new transformation to it.

Thanks again,

Mark

I’m confident that information is not stored with the Layer, not even with a Smart Object, because the Layer’s position at some previous time is generally irrelevant.

Rotation, Scale, Skew, … are different for a Smart Object naturally – unfortunately they can not be directly retrieved as fas as I know.

And Type Layers are special cases anyhow.

if I open the free transform tool on the smart object, the current transformations (e.g., x, y, rotational angle, scale, etc)

But x and y are not related to the offset of a previous transformation, but the current position.

And as I already mentioned this information is not Script-accessible to the best of my knowledge (and others have tried, too).

Basically I need to replace the smart object with the layers in the smart object and transform them in such a way that they match the transformations applied to the smart object. I want to actually extract the layers, and not just edit the linked SO.

I think you are going about this less than ideally, especially as Warps, perspectival transformations etc. might be difficult to evaluate.

One can use "New Smart Object via Copy" instead, open the SO and hide all but one Layer, save, rasterize, repeat for the next Layer etc.

I even attempted a Script on that basis once, but Groups, Layer Masks on Groups and Adjustment Layers, Clipping Masks etc. proved a bit difficult to handle …
