Script that rotates a PNG in Photoshop?

Question

I have the following Photoshop ExtendScript (.jsx) script which rotates the image canvas, but doesn't rotate the contents:
#target photoshop
var doc = app.open(...);       // open the .png file
if (doc.width > doc.height) {  // check if this document is landscape
  doc.rotateCanvas(90);        // rotate the canvas to portrait
  // but how to rotate the contents?
I would like to rotate the entire image, contents included. I've  tried also rotating all the document's layers, and art layers, but  nothing works.

While the code look good it may not work??? You see it does not insure what ruler units is.   So if your ruler units were set to something like persent the if statement would read 
if ( 100% is greater then 100% )  rotate
I have a script like that RotatePortrait.jsx  to rotate portrait to landscape looks like this

Rotate();
function Rotate() {
// validate that a document is open
if (documents.length < 1) {
alert("No Open Document!");
return;
var orig_ruler_units = app.preferences.rulerUnits;
app.preferences.rulerUnits = Units.PIXELS;
// Rotate portrait to landscape orientation
if (activeDocument.height > activeDocument.width) activeDocument.rotateCanvas(90);
// Reset units to original settings
app.preferences.rulerUnits = orig_ruler_units;
