Introduction
About this reference
This reference section describes the objects and commands in Illustrator’s JavaScript
type library. All of the classes in the type library are presented alphabetically. The
chapter concludes with a list of all of the constants in the Illustrator type library.
Each class listing includes the following:
• Properties of the class, including value type, read-only status, and
an explanation.
(cid:127) Methods for the class. Constants and value types needed by the
method are shown in bold face. Required terms are shown in
plain face. All items surrounded by brackets [ ] are optional.
(cid:127) Notes to explain special issues.
(cid:127) Script examples.
About the script examples
Many of these examples do not show the most efficient way to construct a JavaScript
statement, but they are written to be easy to read and understand. Error checking code,
for example, is brief in most of the examples—the point is to show you how to address
and work with the Illustrator objects. Many of the examples may be combined to make
scripts with greater functionality.
Illustrator’s object model
A good understanding of Illustrator’s object model will improve your scripting
abilities. This diagram shows the containment hierarchy of the object model, starting
with the Application object. It is useful to note that all text classes as well as the Layer
and GroupItem classes can contain additional objects of the same class which can, in
turn, contain additional nested objects.

Referencing and Creating Objects in JavaScript
As the object model diagram shows, all objects are arranged in a hierarchy. To obtain a reference to
a specific object you need to navigate the hierarchy. For example, to store a reference to the first
path item in the second layer of the active document in the variable pathRef you would write:
pathRef = activeDocument.layers[1].pathItems[0];
Note: All array references in JavaScript are zero-based. That is, the first element of an array is
index [0].
You can refer to objects in a collection by index number ( [ i ] ) or by name. For example, you can
refer to the "Black" swatch as:
activeDocument.swatches[4] or
activeDocument.swatches["Black"]
The following collection objects do not have names. You can only reference them by index.
(cid:127) Characters
(cid:127) GradientStops
(cid:127) Paragraphs
(cid:127) PathPoints
(cid:127) TextLines
(cid:127) Words
Since all JavaScript scripts are executed from within the Illustrator application, a specific reference
to the application object is not required. For example, to assign the active document in Illustrator
to the variable frontMostDocument, you would reference the activeDocument property of the
application object as follows:
frontMostDocument = activeDocument;
There are a number of objects that cannot be obtained by using the hierarchy shown in the object
model diagram. These objects must created explicitly by defining a variable, using the new object
constructor, and assigning objects or values to them.
For example, to create the new CMYKColor object, newCMYKColor, you would write:
var newCMYKcolor = new CMYKColor();

(cid:127) CMYKColor
(cid:127) Color
(cid:127) EPSSaveOptions
(cid:127) ExportOptionsFlash
(cid:127) ExportOptionsGIF
(cid:127) ExportOptionsJPEG

(cid:127) PatternColor
(cid:127) PDFOpenOptions
(cid:127) PDFSaveOptions

(cid:127) SpotColor
The following example demonstrates how to create a new SaveOptionsEPS object, assign values to
it, and save it to a file named \temp\sample.eps.
// Create an EPS-save option object
var fileSpec = new File("//temp/sample.eps");
var type = ExportType.EPS
var newSaveOptions = new SaveOptionsEPS();
// Set the options to define how the EPS document is saved by Illustrator
newSaveOptions.embedAllFonts = true;
newSaveOptions.compatibility = Compatibility.ILLUSTRATOR7;
newSaveOptions.preview = EPSPreview.COLORTIFF;
// Save the active document
activeDocument.saveAs(fileSpec, type, newSaveOptions);
