Re: Need help cleaning up a script and adding loop

here are some functions to help you scale the last layer to the canvas size

matchLastLayerTocanvas();

 

 

function matchLastLayerTocanvas(){

 

 

 

 

  try{activeDocument.backgroundLayer;var a=0 }catch(e){ var a = 1; };

  // select last art layer::

  while(true){

   ref = new ActionReference();

   ref.putIndex( charIDToTypeID( 'Lyr ' ), a );//refer the layer without selecting it

   try{var desc = executeActionGet(ref);}catch(err){break;}// when the index is bigger there will be an error, the try will stop the wile loop

     var ls = desc.getEnumerationValue(stringIDToTypeID("layerSection"));//get the king( layerSectionStart ) and (layerSectionEnd) are the LayerSets

     // layer SectionContent is a normal layer

     ls = typeIDToStringID(ls);// convert to string

     if(ls == 'layerSectionContent'){// if it's not a LayerSet

        if(!desc.hasKey(stringIDToTypeID("adjustment"))){// and if is not an adjutment layer

      makeActiveByIndex(a);// select the layer

      break;

        }

     }

   a++;

  }

 

 

  var dw = parseFloat(app.activeDocument.width);

  var dh = parseFloat(app.activeDocument.height);

  var lb = app.activeDocument.activeLayer.bounds;

  var lx = parseFloat(lb[0]);

  var ly = parseFloat(lb[1]);

  var lw = parseFloat(lb[2]) - lx;

  var lh = parseFloat(lb[3]) - ly;

 

 

  var resw = (100*dw)/lw;// calculate the procent needed to scale so it will match the doc size

  var resh = (100*dh)/lh;

 

 

  TrnsfWithLeftTopCorner(-lx, -ly, resw, resh);

}

function makeActiveByIndex(idx){

  var idslct = charIDToTypeID( "slct" );

     var desc248 = new ActionDescriptor();

     var idnull = charIDToTypeID( "null" );

         var ref151 = new ActionReference();
