Nearest Neighbour transform script crash

[Ghoul Fool]

DO NOT TRY THIS AT HOME!

In trying to script a transform that uses wither bicubic automatic or neares tneighbour transforms I managed to crash Photoshop with a script:

It creates a new document, with a new layer and then transforms it down 90% by either bicubic automatic (works fine) or Nearest Neighbour - Crash!

// USE THIS SCRIPT AT YOUR OWN RISK
// SAVE AND CLOSE ALL PHOTOSHOP DOCUMENTS
// YOU HAVE BEEN WARNED!!!

displayDialogs = DialogModes.ERROR; // OFF

var docRef = app.documents.add(20, 20, 72, "temp");
srcDoc = app.activeDocument;

duplicate_layer("temp");


transform_by_type("Nrst") // THIS WILL CRASH PHOTOSHOP


function transform_by_type(transformtype)
{

  // =======================================================
  var idTrnf = charIDToTypeID( "Trnf" );
  var desc5623 = new ActionDescriptor();
  var idnull = charIDToTypeID( "null" );
  var ref1379 = new ActionReference();
  var idLyr = charIDToTypeID( "Lyr " );
  var idOrdn = charIDToTypeID( "Ordn" );
  var idTrgt = charIDToTypeID( "Trgt" );
  ref1379.putEnumerated( idLyr, idOrdn, idTrgt );
  desc5623.putReference( idnull, ref1379 );
  var idFTcs = charIDToTypeID( "FTcs" );
  var idQCSt = charIDToTypeID( "QCSt" );
  var idQcsa = charIDToTypeID( "Qcsa" );
  desc5623.putEnumerated( idFTcs, idQCSt, idQcsa );
  var idOfst = charIDToTypeID( "Ofst" );
  var desc5624 = new ActionDescriptor();
  var idHrzn = charIDToTypeID( "Hrzn" );
  var idPxl = charIDToTypeID( "#Pxl" );
  desc5624.putUnitDouble( idHrzn, idPxl, -0.000000 );
  var idVrtc = charIDToTypeID( "Vrtc" );
  var idPxl = charIDToTypeID( "#Pxl" );
  desc5624.putUnitDouble( idVrtc, idPxl, -0.000000 );
  var idOfst = charIDToTypeID( "Ofst" );
  desc5623.putObject( idOfst, idOfst, desc5624 );
  var idWdth = charIDToTypeID( "Wdth" );
  var idPrc = charIDToTypeID( "#Prc" );
  desc5623.putUnitDouble( idWdth, idPrc, 90.000000 );
  var idHght = charIDToTypeID( "Hght" );
  var idPrc = charIDToTypeID( "#Prc" );
  desc5623.putUnitDouble( idHght, idPrc, 90.000000 );
  var idIntr = charIDToTypeID( "Intr" );
  var idIntp = charIDToTypeID( "Intp" );

  var idTransform = stringIDToTypeID( transformtype );
  desc5623.putEnumerated( idIntr, idIntp, idTransform );
  executeAction( idTrnf, desc5623, DialogModes.NO );

}


// function DUPLICATE LAYER (str)
// --------------------------------------------------------
function duplicate_layer(str)
{

  // duplicate layer normaly
  // =======================================================
  var id1572 = charIDToTypeID( "Dplc" );
  var desc350 = new ActionDescriptor();
  var id1573 = charIDToTypeID( "null" );
  var ref184 = new ActionReference();
  var id1574 = charIDToTypeID( "Lyr " );
  var id1575 = charIDToTypeID( "Ordn" );
  var id1576 = charIDToTypeID( "Trgt" );
  ref184.putEnumerated( id1574, id1575, id1576 );
  desc350.putReference( id1573, ref184 );
  var id1577 = charIDToTypeID( "Nm  " );
  desc350.putString( id1577, str );         // layer name here
  var id1578 = charIDToTypeID( "Vrsn" );
  desc350.putInteger( id1578, 2 );
  executeAction( id1572, desc350, DialogModes.NO );
}

But the function works fine with 

transform_by_type("bicubicAutomatic");

Thought someone else out to know.

I've stabilised it with an if /else:

  if (transformtype == "nn") // avoids passing string directly to stringIDToTypeID
  {
    var idNrst = charIDToTypeID( "Nrst" );
    desc5623.putEnumerated( idIntr, idIntp, idNrst );
  }
  else
  {
    var idbicubicAutomatic = stringIDToTypeID( "bicubicAutomatic" );
    desc5623.putEnumerated( idIntr, idIntp, idbicubicAutomatic  );
  }
