 Photoshop CS3 Scripting Basics     17

appRef.Preferences.RulerUnits = originalRulerUnits

2. Save file as a text file with a 

.vbs

 file name extension.

3. Double-click the file in Windows Explorer to run the script. 

The script opens Photoshop CS3.

Follow these steps to create and run a JavaScript that displays the text Hello World! in a Photoshop CS3 
document. 

Because you will be actually using Photoshop CS3 to run your JavaScripts, it is not necessary to include 
code that opens Photoshop CS3 at the beginning of the script. 

Adobe has created the Extend Script scripting language to augment JavaScript for use with 
Photoshop CS3. You can use the Extend Script command 

#target

 to target the Photoshop CS3 

application and create the ability to open JavaScripts that manipulate Photoshop CS3 from 
anywhere in your file system. See the “Script UI” chapter of the JavaScript Tools Guide for more 
information.

1. Type the following script. 

Entering comments is optional.

// Hello Word Script
// Remember current unit settings and then set units to
// the value expected by this script
var originalUnit = preferences.rulerUnits
preferences.rulerUnits = Units.INCHES

// Create a new 2x4 inch document and assign it to a variable
var docRef = app.documents.add( 2, 4 )

// Create a new art layer containing text
var artLayerRef = docRef.artLayers.add()
artLayerRef.kind = LayerKind.TEXT

// Set the contents of the text layer.
var textItemRef = artLayerRef.textItem
textItemRef.contents = "Hello, World"

// Release references
docRef = null
artLayerRef = null
textItemRef = null

// Restore original ruler unit setting
app.preferences.rulerUnits = originalUnit

2. Save file as a text file with a 

.jsx 

file name extension in the Presets/Scripts folder in your Adobe 

Photoshop CS3 directory.

You must place your JavaScripts in the Presets/Scripts folder in order to make the scripts 
accessible from the File > Scripts menu in Photoshop CS3. The scripts do not appear on the File 
> Scripts menu until you restart the application.
