Script support in Adobe Illustrator CS4

Illustrator scripting supports VBScript and JavaScript scripts for Windows, and AppleScript and JavaScript 
scripts for Mac OS.

N

OTE

: 

Also, Adobe scripting-enabled applications, including Illustrator, support ExtendScript, Adobe’s 

extended implementation of ECMA JavaScript. ExtendScript files are distinguished by the 

.jsx

 extension. 

Giving your JavaScript files a 

.jsx

 extension allows you to take advantage of ExtendScript features and 

tools.

ExtendScript features

ExtendScript offers all standard JavaScript features, plus a development and debugging environment, the 
ExtendScript Toolkit (ESTK). The ESTK is installed with all scriptable Adobe applications.

The ESTK includes an Object Model Viewer that contains complete documentation of the methods and 
properties of JavaScript objects.

For information on accessing the ESTK and the Object Model Viewer, see 

“Viewing the JavaScript object 

model” on page 8

.

ExtendScript tools

ExtendScript also provides various tools and utilities, including the following:

➤

A localization utility

➤

Tools that allow you to combine scripts and direct them to particular applications

➤

Platform-independent file and folder representation

➤

Tools for building user interfaces to your scripts

➤

A messaging framework that allows you to send and receive scripts and data among 
scripting-enabled Adobe applications

For details of these and other features, see 

JavaScript Tools Guide

.

Script file extensions

For a file to be recognized by Adobe Illustrator CS4 as a valid script file, the file must have the correct file 
name extension:
