    resize width of layer to canvas width

    hilukasz Level 1

      I'm having some trouble resizing a layer width to canvas width.


      I know one way that works and it involves creating new document, resizing, then pasting back in. This seems extranious it seems there should be an easier way.

          var width = doc.width;
          var bounds = layer.bounds;
          var height = bounds[3]-bounds[1]; \\get height because I want this the same
          var width = doc.width;
          layer.resize (width, height, AnchorPosition.MIDDLECENTER);


      this seems to fail even though it seems the documentation says it should work? maybe I am misunderstanding.

          I would say either the layer and doc references are not valid or the layer is not visible.

            When dealing with layers the resize is done with percentage, so your

            layer width and height are allways 100% To make it fit the document you need to work out the ratio and then resize.

            This should do what you want....

            function main(){
                if(!documents.length) return;    
                if (activeDocument.activeLayer.isBackgroundLayer) return;
            function fitLayerToDoc(){   
            var strtRulerUnits = app.preferences.rulerUnits; 
            var strtTypeUnits = app.preferences.typeUnits; 
            app.preferences.rulerUnits = Units.PIXELS; 
            app.preferences.typeUnits = TypeUnits.PIXELS;            
            var docWidth = activeDocument.width.value; 
            var LB = activeDocument.activeLayer.bounds;               
            var LWidth = LB[2].value - LB[0].value;                
            var percentageWidth = ((docWidth/LWidth)*100); 
            align( 'AdRg');
            app.preferences.rulerUnits = strtRulerUnits; 
            app.preferences.typeUnits = strtTypeUnits;
            function align(method) { 
               var desc = new ActionDescriptor();
                       var ref = new ActionReference();
                       ref.putEnumerated( charIDToTypeID( "Lyr " ), charIDToTypeID( "Ordn" ), charIDToTypeID( "Trgt" ) ); 
                   desc.putReference( charIDToTypeID( "null" ), ref ); 
                   desc.putEnumerated( charIDToTypeID( "Usng" ), charIDToTypeID( "ADSt" ), charIDToTypeID( method ) );
               executeAction( charIDToTypeID( "Algn" ), desc, DialogModes.NO );

              this seems to work however, for some reason it still leaves out a few px on 3 sides when I use vector shape objects. not sure if this is a glitch, but as vector it seems to work perfect.
