,

To familiarize yourself with this objects, properties, and commands in the scripting references, do the 
following:

●

In the Adobe Photoshop CS3 AppleScript Scripting Reference or in the Photoshop CS3 AppleScript 
Dictionary, look up the 

text-object

 properties and methods. 

●

In the Adobe Photoshop CS3 Visual Basic Scripting Reference, or in the Visual Basic Object Browser 
look up the 

TextItem

 property of the 

ArtLayer

 object. To find the properties and methods you can 

use with a text layer, look up the 

TextItem

 object. 

●

In the Adobe Photoshop CS3 JavaScript Scripting Reference, or in the ExtendScript Object Model 
Viewer, look up the 

textItem

 property of the 

ArtLayer

 object. To find the properties and methods 

you can use with a text layer, look up the 

TextItem

 object. 

You use a 

Selection

 object to allow your scripts to act only on a specific, selected section of your 

document or a layer within a document. For example, you can apply effects to a selection or copy the 
current selection to the clipboard. 

The 

Selection

 object is a property of the 

Document

 object. Look up the following for more information:

●

In the Adobe Photoshop CS3 AppleScript Scripting Reference or in the Photoshop CS3 AppleScript 
Dictionary, look up the command 

select

. Also, look up the 

selection

 property of the 

Document

 

object, and the 

selection-object

.

●

In the Adobe Photoshop CS3 Visual Basic Scripting Reference, or in the Visual Basic Object Browser, look 
up 

Selection

 as a property of the 

Document

 object. Also, look up the 

Select

 as a method of the 

Selection

 object.

●

In the Adobe Photoshop CS3 JavaScript Scripting Reference, or in the ExtendScript Object Model Viewer, 
look up 

selection

 as a property of the 

Document

 object. Also, look up the 

select

 as a method of the 

Selection

 object.

You cannot create a new 

Selection

 object. The property 

selection

 

(Selection/selection)

 on 

the 

Document

 object contains a pre-existing selection object for the document. Use the 

select

 

(Select/select)

 command to specify the area for the selection.

To create a selection, you use the 

select/Select/select()

 command of the 

Selection

 object.

You define a selection by specifying the coordinates on the screen that describe the selection’s corners. 
Since your document is a 2-dimensional object, you specify coordinates using the x-and y-axes as follows:

●

You use the x-axis to specify the horizontal position on the canvas.

●

You use the y-axis to specify the vertical position on the canvas. 

The origin point in Photoshop CS3, that is, x-axis = 0 and y-axis = 0, is the upper left corner of the screen. 
The opposite corner, the lower right, is the extreme point of the canvas. For example, if your canvas is 1000 
x 1000 pixels, then the coordinate for the lower right corner is x-axis = 1000 and y-axis = 1000.

You specify coordinate points that describe the shape you want to select as an array, which then becomes 
the argument or parameter value for the 

select/Select/select()

 command.
