Scale layer object height to same as text layer height

[Retsied]

I have 2 layers, 1 is an art layer object, the other is a pure text layer of fixed width. How can I extract the text layer height and use this to set the art layer to the same exact height. I need this to update dynamically, so if I change the texts height, the art layer automatically follows. So copy/paste hard numbers will not work.

I figured I could do this using activeLayer.bounds in some way, but couldn't get this to work.

Any ideas much appreciated, thanks!

My attempt:

doc.activeLayer = doc.artLayers.getByName("TextLayer");

var LB = doc.activeLayer.bounds; 

var textHeight = LB[3].value;

doc.activeLayer = doc.artLayers.getByName("ArtLayer");

doc.activeLayer.resize(undefined, textHeight, AnchorPosition.MIDDLECENTER);

var doc = activeDocument;
var t = doc.artLayers.getByName("TextLayer");
var a = doc.artLayers.getByName("ArtLayer");
var textHeight = t.bounds[3].value - t.bounds[1].value;
var artHeight  = a.bounds[3].value - a.bounds[1].value;
a.resize(undefined, textHeight/artHeight*100, AnchorPosition.MIDDLECENTER);

Thanks for the answer. Could you please describe what this is doing?

• What bound[3]/bound[1] represent?
• Why multiple by 100?

1. Where did you see this?

2 Because you need to specify a percentage

I mean what does bound[3] and bound[1] represent? And why divide the two in the resize function to force the artLayer to the same height as the textLayer?

I ask because I'm trying to do the same exact thing with a different file, with width instead of height and it won't work:

var doc = activeDocument;

var t = doc.activeLayer;

var textWidth = t.bounds[2].value - t.bounds[0].value; 

var bub = doc.artLayers.getByName("My Art Layer");

var a = bub.duplicate();

var artWidth  = a.bounds[2].value - a.bounds[0].value; 

a.resize(textWidth/artWidth*100, undefined, AnchorPosition.MIDDLERIGHT);

Everything is working.

The active layer must be a text layer. And the layer "My Art Layer" should be present and not be empty.

What error occurs?

Hi r-bin, great job! this inspires me in some projects. How do I keep the proportion of the object in that same example written by you? Thank you.

Disregard my question, I have already found an alternative with some changes.

activeDocument.activeLayer = activeDocument.activeLayer;    
var LB = activeDocument.artLayers.getByName("TextLayer").bounds;    
var IB = activeDocument.artLayers.getByName("ArtLayer").bounds;  
var height = LB[3]-LB[1]; dheight = IB[3]-IB[1];       
var porcentage = ((height/dheight)*100); 
app.activeDocument.activeLayer.resize(porcentage, porcentage, AnchorPosition.MIDDLECENTER);
