Layer scale factor

[Luis Morcillo]

Let's say I create a text layer with 50pt font size, then I transform the layer to make it bigger. Is there a variable that saves the scale factor?

Thanks in advance.

I just tested in Photoshop CC and there the result of scaling a Type Layer seems to be a Type Layer with the correspondingly larger/smaller type size. (edited)

Thanks! That's right, and I'd like to know if there's a scale value inside the layer, accessible through scripting.

I'll explain the problem a bit: in CC, when you do what I explain in the opening post, you can see in the interface a bigger value for the text size, but when you get "layer.textItem.size" through scripting, the size is the original one, not the one you see in the interface (the bigger). That didn't happen in CS5.

So I was thinking if it might be possible to calculate the new text size of the layer with that original text size * the layer scale factor (in case there's a variable that has that value).

Does this help?

if (app.documents.length > 0) {

if (app.activeDocument.activeLayer.kind == LayerKind.TEXT) {

var ref = new ActionReference();

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

var layerDesc = executeActionGet(ref);

var textDesc = layerDesc.getObjectValue(stringIDToTypeID('textKey'));

checkDesc2 (textDesc.getObjectValue(stringIDToTypeID("transform")));

}

Please note I edited the code, I had omitted a line.

There seems to be a problem with

textDesc.getObjectValue(stringIDToTypeID("transform"))

[c.pfaffenbichler]

Has the Layer been transformed at all?

Otherwise there would be no need for the key, I guess; either using hasKey() or wrapping it in a try-clause should work.

[JJMack]

Understood I'll just put it in a try

[c.pfaffenbichler]

I should have thought of that …

Note that CC2014 works differently from CC2012 and I've not found a reliable way for CS6. This is the code I have for getting the paragraph text box extents.

getTextExtentsCC2014: function (text_item) { 



        app.activeDocument.activeLayer = text_item.parent
        var ref = new ActionReference()
        ref.putEnumerated( charIDToTypeID("Lyr "), charIDToTypeID("Ordn"), charIDToTypeID("Trgt") )
        var action = executeActionGet(ref) 
        var textKey = action.getObjectValue(stringIDToTypeID('textKey'))
        var bounds = textKey.getObjectValue(stringIDToTypeID('bounds'))
        var width = bounds.getUnitDoubleValue (stringIDToTypeID('right'))
        var height = bounds.getUnitDoubleValue (stringIDToTypeID('bottom')) 
        var x_scale = 1
        var y_scale = 1
        if (textKey.hasKey(stringIDToTypeID('transform'))) {  
            var transform = textKey.getObjectValue(stringIDToTypeID('transform'))
            x_scale = transform.getUnitDoubleValue (stringIDToTypeID('xx'))
            y_scale = transform.getUnitDoubleValue (stringIDToTypeID('yy'))
        } 
        x_scale *= width / text_item.width
        y_scale *= height / text_item.height
        return { 
            x:Math.round(text_item.position[0]), 
            y:Math.round(text_item.position[1]), 
            width:Math.round(width*x_scale), 
            height:Math.round(height*y_scale) }




},

            }




},

Thanks for the replies. I'll give it a go during the week
