What is scripting?
A script is a series of commands that tells Illustrator to perform one or more tasks. These tasks can be

Graphic design is a field characterized by creativity, but aspects of the work are anything but creative. In
fact, you probably notice that the time you spend placing and replacing images, correcting errors in text,
and preparing files for printing at an image-setting service provider often reduces the time you have
available for doing creative work.
With a small investment of time and effort, you can learn to write short, simple scripts that perform
repetitive tasks for you. As your scripting skills grow, you can move on to more complex scripts.
Scripting also can enhance your creativity, by quickly performing tasks you might not have time to try. For
example, you could write a script to systematically create a series of objects, modifying the new objects’
position, stroke, and fill properties along the way. You also could write a script that accesses built-in
transformation matrix functions to stretch, scale, and distort a series of objects. Without scripting, you
would likely miss out on the creative potential of such labor-intensive techniques.
What about actions?
Both actions and scripts are ways of automating repetitive tasks, but they work very differently:
➤
Actions use a program’s user interface to do their work. As an action runs, menu choices are executed,
objects are selected, and recorded paths are created. Scripts do not use a program’s user interface to
perform tasks, and scripts can execute faster than actions.
➤
Actions have very limited facilities for getting and responding to information. You cannot add
conditional logic to an action; therefore, actions cannot make decisions based on the current
situation, like changing the stroke type of rectangles but not ellipses. Scripts can get information and
make decisions and calculations based on the information they receive from Illustrator.
➤
A script can execute an action, but actions cannot execute scripts.

Script support in Adobe Illustrator CS4
Illustrator scripting supports VBScript and JavaScript scripts for Windows, and AppleScript and JavaScript
scripts for Mac OS.
NOTE: 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:
Script type
File type

Platforms
AppleScript
compiled script
OSAS file
.scpt
Mac OS

CHAPTER 1: Introduction
Viewing sample scripts
8
Viewing sample scripts
Adobe provides sample scripts for many objects, properties, and methods in the Illustrator CS4 DOM. You
can view script samples in two locations:
➤
In the /Scripting/Sample Scripts folder in your Illustrator CS4 installation directory
➤
In the Adobe Illustrator CS4 scripting reference for your scripting language, located in the
/Scripting/Documentation folder in your Illustrator CS4 installation directory
Viewing the object model
Each of the supported scripting languages provides a facility for viewing the scripting objects defined by
Illustrator, with reference details.
Viewing the JavaScript object model
To view the JavaScript object model for Illustrator, follow these steps:
1. Start the ESTK.
In a default Adobe installation, the ESTK is in the following location:
➣
Windows:
system drive\Program Files\Adobe\Adobe Utilities\ExtendScript Toolkit CS4
➣
Mac OS:
system drive:Applications:Utilities:Adobe Utilities:ExtendScript Toolkit CS4
2. In the ESTK, choose Help > Object Model Viewer.
3. In the Object Model Viewer window, select Adobe Illustrator CS4 Type Library from the Browser
drop-down list.
Several extended sample scripts are available in the /Scripting/Sample Scripts folder in your Illustrator
CS4 installation directory.
You also can view script samples and information about individual classes, objects, properties, methods,
and parameters in Adobe Illustrator CS4 Scripting Reference: JavaScript, located in the
/Scripting/Documentation folder in your Illustrator CS4 installation directory.
Viewing the AppleScript object model
Apple provides a Script Editor with all Mac OS systems. You can use Script Editor to view the AppleScript
dictionary that describes Illustrator objects and commands.
For details of how to use Script Editor, see Script Editor Help.
1. Start Script Editor.
NOTE: In a default Mac OS installation, Script Editor is in Applications:AppleScript:Script
Editor. If you cannot find the Script Editor application, you must reinstall it from your Mac OS system
CD.
CHAPTER 1: Introduction
Executing scripts

2. Choose File > Open Dictionary. Script Editor displays an Open Dictionary dialog.
3. In the Open Dictionary dialog, find and select Adobe Illustrator CS4, and click Open.
Script Editor displays a list of the Illustrator objects and commands, which include the properties and
elements associated with each object and the parameters for each command.
Several extended sample scripts are in the :Scripting:Sample Scripts folder in your Illustrator CS4
installation directory.
You also can view script samples and information about individual classes, objects, properties, methods
and parameters in Adobe Illustrator CS4 Scripting Reference: AppleScript, located in the
:Scripting:Documentation folder in your Illustrator CS4 installation directory.
Viewing the VBScript object model
VBScript provides a type library you can use to view Illustrator object properties and methods. This
procedure explains how to view the type library through any Microsoft Office program. Your VBScript
editor probably provides access to the library. For information see your editor’s Help.
1. In any Microsoft Office application, choose Tools > Macro > Visual Basic Editor.
2. In the Visual Basic Editor, choose Tools > References.
3. In the dialog that appears, select the check box for Adobe Illustrator CS4 Type Library, and click OK.
4. Choose View > Object Browser, to display the Object Browser window.
5. Choose “Illustrator” from the list of open libraries in the top-left pull-down menu of the Object
Browser window.
Several extended sample scripts are in the /Scripting/Sample Scripts folder in your Illustrator CS4
installation directory.
You also can view script samples and information about individual classes, objects, properties, methods,
and parameters in Adobe Illustrator CS4 Scripting Reference: VBScript, located in the
/Scripting/Documentation folder in your Illustrator CS4 installation directory.
Executing scripts
The Illustrator interface includes a Scripts menu (File > Scripts) that provides quick and easy access to your
scripts.
Scripts can be listed directly as menu items that run when you select them. See “Installing scripts in the
Scripts menu” on page 10.
You can navigate from the menu to any script in your file system and then run the script. See “Executing
scripts from the Other Scripts menu item” on page 10.
You also can have JavaScript scripts with a .jsx extension start automatically when you launch the
application. For information, see “Startup scripts (.jsx scripts only)” on page 10.
CHAPTER 1: Introduction
Executing scripts
10
Installing scripts in the Scripts menu
To include a script in the Scripts menu (File > Scripts), save the script in the Scripts folder, located in the
/Illustrator CS4/Presets folder in your Illustrator CS4 installation directory. The script’s filename,
minus the file extension, appears in the Scripts menu.
Scripts that you add to the Scripts folder while Illustrator is running do not appear in the Scripts menu until
the next time you launch Illustrator.
Any number of scripts can be installed in the Scripts menu. If you have many scripts, use subfolders in the
Scripts folder to help organize the scripts in the Scripts menu. Each subfolder is displayed as a separate
submenu containing the scripts in that subfolder.
Executing scripts from the Other Scripts menu item
The Other Scripts item at the end of the Scripts menu (File > Scripts > Other Scripts) allows you to execute
scripts that are not installed in the Scripts folder.
Selecting Other Scripts displays a Browse dialog, which you use to navigate to a script file. When you select
the file, the script is executed.
Only files that are of one of the supported file types are displayed in the browse dialog. For details, see
“Script support in Adobe Illustrator CS4” on page 7.
Startup scripts (.jsx scripts only)
JavaScript scripts with a .jsx file extension can be installed in one of two folders, so the scripts run
automatically when you launch Illustrator and each time you run a script. The folders are:
➤
An application-specific startup scripts folder, which contains scripts for Illustrator CS4
➤
A general startup scripts folder, which contains scripts that run automatically when you start any
Creative Suite 4 application
Application-specific startup scripts folder
You must place application-specific startup scripts in a folder named Startup Scripts, which you create
in the Illustrator installation directory.
For example, when Illustrator CS4 is installed to its default location, you would create the
Startup Scripts folder at the following location:
➤
Windows:
C:\Program Files\Adobe\Adobe Illustrator CS4\Startup Scripts\
➤
Mac OS:
/Applications/Adobe Illustrator CS4/Startup Scripts/
JavaScript scripts with a .jsx extension placed in the Startup Scripts folder run automatically when:
➤
The application is launched.
➤
Any JavaScript file is selected from the Scripts menu (File > Scripts).
CHAPTER 1: Introduction
Changes since CS3
11
General startup scripts folder
The general startup scripts folder contains scripts that run automatically when you start any Creative
Suite 4 application. You create the folder in the following location:
➤
Windows:
Program Files/Common Files/Adobe/Startup Scripts CS4/Illustrator
➤
Mac OS:
:Library:Application Support:Adobe:Startup Scripts CS4:Illustrator
If a script in the general startup folder is meant to be executed only by Illustrator, the script must include
the ExtendScript #target directive (#target illustrator) or code like the following:
if( BridgeTalk.appName == "illustrator" ) {
//continue executing script
}
For details, see JavaScript Tools Guide.

Known issues
➤
Scripts that create, save, and close many Illustrator files should periodically quit and relaunch
Illustrator. The recommended maximum number of files to process before quitting and relaunching
Illustrator is:
➣
Windows
500 files
➣
Mac OS
1000 files
For more information on quitting and relaunching Illustrator, see “Launching and activating
Illustrator” on page 25 and “Quitting Illustrator” on page 26.
➤
The “An Illustrator error occurred: 1346458189 (“PARM”)” alert may be popped when badly written
scripts are repeatedly run in Illustrator from the ESTK.
Scripters need to be very careful about variable initialization and namespace conflict when pushing a
batch of Illustrator scripts repeatedly for execution in Illustrator via the ESTK in one Illustrator session.
Each script run is executed within the same persistent ExtendScript engine within Illustrator.
The ESTK debugger uses BridgeTalk to communicate with Illustrator. A single global, persistent,
ExtendScript engine inside Illustrator handles all BridgeTalk communications. The net effect is that the
state of the ExtendScript engine is cumulative to all scripts that ran previously. Issues with script code
that may cause this problem are:
➣
Reading uninitialized variables.
➣
Global namespace conflicts, such as when two globals from different scripts are clobbering each
other.
2
The Illustrator Scripting Object Model
A good understanding of the Illustrator object model will improve your scripting abilities. The following
figure shows the containment hierarchy of the object model, starting with the application object. Note
that the layer and group item classes can contain nested objects of the same class which can, in turn,
contain additional nested objects.
In addition to this application-specific object model, JavaScript provides certain utility objects, such as the
File and Folder objects, which give you operating-system-independent access to the file system. For
details, see JavaScript Tools Guide.
17
CHAPTER 2: The Illustrator Scripting Object Model
Object-naming conventions
18
Object-naming conventions
There is one object model for the Illustrator scripting interface, but actual object names vary slightly in the
different scripting languages:
➤
AppleScript names are lower case, and individual words are separated by a space; for example:
graphic style
➤
VBScript names are capitalized, and additional words in the name are indicated by uppercase initial
letters; for example:
GraphicStyle
➤
JavaScript names begin with lowercase letters, and additional words in the name are indicated by
uppercase initial letters; for example:
graphicStyle
This chapter uses generic object and property names, but you can easily apply these conventions to
determine the corresponding language-specific names.
Throughout this document, names of properties, methods, and object are in a monospaced font.
Top-level (containing) objects
Use these objects to access global information about the Illustrator application or an individual document.
Application
The properties of the application object give your script access to global values, such as:
➤
User preferences, which a user sets interactively in the Illustrator application by using the
Preferences dialog (Edit > Preferences).
➤
System information like installed fonts (the text fonts property) and printers (the printer list
property).
Also, there are properties that provide application-specific information and higher-level information
about any open documents:
➤
Application information like the installation path, version, and whether Illustrator is visible.
➤
The current active document; that is, the art canvas that is displayed and accepting user input.
➤
All open documents.
The application object’s methods or commands allow your script to perform application-wide actions;
for example:
➤
Open files
➤
Undo and redo transactions
➤
Quit Illustrator
CHAPTER 2: The Illustrator Scripting Object Model
The artwork tree
19
Document
The document object, which your scripts can create or access through the application object, represents
an art canvas or loaded Illustrator file. The document object’s properties give you access to the document’s
content; for example:
➤
The current selection, or art objects that the user selected in the document
➤
All contained art objects, called page items, that make up the artwork tree
➤
Art objects of particular types, like symbols and text frames
➤
All layers and the currently active layer
Document properties also tell you about the state of the document itself; for example:
➤
User settings for the document, such as ruler units
➤
Whether the document was saved since the last alteration of content
➤
The path of the associated file
The document object’s methods allow your scripts to act on the document; for example:
➤
Save to an Illustrator file or save as the various supported file formats
➤
Activate or close a document
➤
Print the document. Your scripts can select a printer by referencing a print options object, or they
can reference available printers through the application object’s printer list property.
Layer
The layer object provides access to the contents, or artwork tree, of a specific layer. You access the layer
object through the document object. The layer object properties provide access to, or information about,
the layer, such as:
➤
Whether the layer is visible or locked.
➤
The layer’s opacity (overall transparency) and z order position (position in the stacking order).
➤
Art-creation preferences for the layer, like artwork knockout and blending mode.
The artwork tree
The content of an Illustrator document is called the artwork tree. Artwork is represented by the following
objects:
➤
compound path item
➤
graph item
➤
group item
➤
legacy text item
CHAPTER 2: The Illustrator Scripting Object Model
➤
mesh item
➤
non native item
➤
path item
➤
placed item
➤
plugin item
➤
raster item
➤
symbol item (see “Dynamic objects” on page 24)
➤
text frame
The artwork tree
20
Your scripts can access and manipulate art objects through collections in the document and layer objects.
There are two types of art-object collections:
➤
Collection objects that correspond to each individual artwork object type, such as the graph items
object or the mesh items object.
➤
The page items object, which includes art objects of all types.
Also, you can use the group item object to reference a grouped set of art items.
You can create new art objects using the make command (AppleScript) or add method of an artwork item
collection object. For example, to create a new path item object:
AppleScript
set myPathItem to make new path item in current document
JavaScript
var myPathItem = activeDocument.pathItems.add();
VBScript
Set myPathItem = appRef.ActiveDocument.PathItems.Add()
The following artwork collections do not allow the creation of new objects using the make command or
add method:
➤
graph items object
➤
mesh items object
➤
plugin items object
➤
legacy text items object
For details on creating objects of these types, see the Adobe Illustrator CS4 Scripting Reference for your
language.
Art styles
Your script can apply a graphic style to artwork using the graphic style object. To apply a graphic style,
use the graphic styles property of the document object to access the apply to method of the graphic
style object.
Similarly, the brush object allows you to specify the brush to apply to artwork. You access any brush
through the brushes collection object, which is a property of the document object.
CHAPTER 2: The Illustrator Scripting Object Model
Text objects
21
Color objects
Your script can apply a color, pattern or gradient to a path item object, using the fill color or
stroke color properties:
➤
Scripts can define new color swatches using the make command or add method of the swatches
object. Your script also can create a new spot color, using the make command or add property of the
spots object.
➤
You can define the attributes of an ink object using the ink info object, which is an ink object
property. You access ink objects through the ink list property of the document object.
The following objects allow you to create colors within defined color spaces:
➤
The RGB color object, using the range 0.0 to 255.0 for the each of the three individual color values.
➤
The CMYK color object, using the percentage values 0.0 through 100.0 for each of the four individual
color values.
➤
The grayscale color or LAB color objects, using the same range and number of values that you use
in the Illustrator application.
Text objects
When you type content in an Illustrator document, the type automatically becomes a text frame object
and, at the same time, a story object.
To observe this, open a new document in Illustrator and use the horizontal text tool to type some text,
then use the vertical text tool to type more text. Finally, create a rectangle and type some text inside it.
Now run the following JavaScript script:
var myDoc = app.activeDocument
alert("There are " + myDoc.textFrames.length + " text frames.")
alert("There are " + myDoc.stories.length + " stories.")
Text frames
There are three types of text frames:
➤
point
➤
area
➤
path
CHAPTER 2: The Illustrator Scripting Object Model
Text objects
22
To create a specific kind of text frame, use the kind property of the text frames object in AppleScript. The
JavaScript and VBScript text frames objects contain specific methods for creating area text frames and
path text frames.
As in the Illustrator application, you can thread area or path text frames.
To thread existing text frames, use the next frame or previous frame property of the text frame object.
Threaded frames make a single story object.
For information on creating or threading text frames, see the chapter in this manual for your scripting
language.
Text geometry
While the three kinds of text frames have common characteristics, like orientation, each has
type-specific qualities, as reflected in the text frame object’s properties. For example:
➤
An area text frame can have rows and columns, which you access through the row count and
column count properties.
➤
Path text has start T value and end T value properties that indicate where on the path the text
begins and ends.
➤
Area and path text frames are associated with a text path object, which is specified using the
text frame object’s text path property. The text path defines the text frame’s position and
orientation (horizontal or vertical) on the artboard (while the text frame object’s orientation
property defines the orientation of text within the text frame).
The text path property is not valid for point text, because point-text position and orientation are
defined completely by the properties of the text frame itself.
NOTE: A text path is not the same as a path art item. Text paths are associated with path art items that can
be accessed and manipulated to modify the appearance of the associated text frame.
Objects that represent text content
Within a text frame or story, the actual text content can be accessed as any of the following objects:
➤
characters
➤
words
➤
paragraphs
➤
lines
A line object is all the characters that fit on one line in a text frame or story object. All text-art items
have at least one line of text, defined as a line object. Text art can have multiple text lines, if the text
contains hard line breaks or its characters flow to a new line because they do not fit in the width of the text
art. Text objects are accessed and identified by collections within the text frame and story objects; for
example, textFrame("My Text Frame").paragraphs or story("My Story").paragraphs.
CHAPTER 2: The Illustrator Scripting Object Model
Text objects
23
Both text frame and story objects have insertion point and text selection properties. The text
frame object’s properties also include the defining features of the text frame, such as:
➤
The frame width, height, and position
➤
Whether the frame is hidden or locked
➤
Whether the text is editable
NOTE: A line object cannot be created in a script. Your script can create character, paragraph, and word
objects.
Text ranges
The various text objects within a text frame or story also are represented collectively by the text range
object. For example, a character is a text range with a length of 1, and a word is a text range that has a
space before it.
You can set the content of a text range object by passing a string using the contents property.
Text styles
Text-style elements, like font, capitalization, and justification, are represented by paragraph
attribute and character attribute objects. These attribute objects are properties of the paragraph
style and character style objects. The paragraph style and character style objects have apply to
and remove methods that allow your script to assign or remove attributes in a specific paragraph,
character, or text range.
You can change the display properties of a text range by applying an appropriate style or providing local
overrides of attributes at the text or paragraph levels:
➤
character style objects apply to sets of one or more characters. They control character features like
font, alignment, leading, language, and capitalization, which are properties of the
character attribute object.
➤
paragraph style objects apply to paragraphs. They control paragraph features like first line
indent, left indent, and right indent, which are properties of the paragraph attribute object.
CHAPTER 2: The Illustrator Scripting Object Model
Dynamic objects
24
Dynamic objects
By creating dynamic objects, you can create data-driven graphics. In the Illustrator application, you use the
Variables panel to create or edit variables like graph data, linked file, text string, and visibility, or variables
whose type is not specified. In scripting, you use the variable object to represent this type of variable.
The variable object’s kind property indicates the type of dynamic data that a variable object holds.
variable objects are document-level objects; you create them in a document object.
NOTE: Do not confuse variable objects with scripting variables. For details on Illustrator variables,
dynamic objects, and data-driven graphics, see Illustrator Help.
Datasets, which collect variables and their associated dynamic data into one object, are represented in
scripting by the dataset object. The dataset object provides methods to update and delete dataset
objects in your scripts.
Symbols
In Illustrator, symbols are art items that are stored in the Symbols panel. Your scripts can create, delete, and
duplicate symbol objects. When you create symbol objects in your script, Illustrator adds them to the
Symbols panel for the target document.
A symbol item is an instance of a symbol object in a document. Each symbol item is linked to its symbol
definition, so changing the definition of a symbol updates all instances of the symbol.
Your script can create, delete, and duplicate symbol items. Symbol items are Illustrator art items; therefore,
they can be treated in the same way as other art items or page items. You can rotate, resize, select, lock,
hide, and perform other operations on symbol items.
Transformations
The matrix object provides access to the power of geometric-transformation matrices. Transformation
matrices in Illustrator store the settings of an operation that scales, rotates, or moves (translates) an object
on a page. There are advantages to using matrices:
➤
By storing transformation values in a matrix object, you can use the values repeatedly on different
objects in your script.
➤
By concatenating rotation, translation, and/or scaling matrices and applying the resulting matrix, you
can perform many geometric transformations with only one script statement.
➤
You can invert matrix values.
➤
You can compare the values of two matrices.
The application object. has commands or methods to create, get, invert, compare, or concatenate
matrices.
The command or method used to apply a matrix is the transform command, which belongs to any type
of object on which transformations can be performed.

Scripting Illustrator
This chapter is an overview of how to use scripting objects to program Illustrator CS4. Specific examples
for the supported scripting languages are in succeeding chapters.
Launching and quitting Illustrator from a script
Your scripts can control the activation and termination of Illustrator.
Launching and activating Illustrator
AppleScript
In AppleScript, you use a tell statement to target Illustrator. The activate command activates Illustrator
if it is not already active.
tell application "Adobe Illustrator"
activate
end tell
JavaScript
Typically, you run JavaScript scripts from the application’s Scripts menu (File > Scripts) or start-up folder, so
there is no need to launch Illustrator from your script.
Information on launching Illustrator in JavaScript is beyond the scope of this guide. For details, search for
“interapplication messaging” or “JavaScript messaging framework” in JavaScript Tools Guide.
VBScript
In VBScript, there are several ways to create an instance of Illustrator:
➤
CreateObject launches Illustrator as an invisible application if it is not already running. If Illustrator is
launched as an invisible application you must manually activate the application to make it visible:
Set appRef = CreateObject("Illustrator.Application")
If you have multiple versions of Illustrator installed on the same machine and use the CreateObject
method to obtain an application reference, using "Illustrator.Application" creates a reference
to the latest Illustrator version. To specifically target an earlier version, use a version identifier at the
end of the string:
For Illustrator 10, use "Illustrator.Application.1"
For Illustrator CS, use "Illustrator.Application.2"
For Illustrator CS2, use "Illustrator.Application.3"
For Illustrator CS3, use "Illustrator.Application.4"
For Illustrator CS4, use "Illustrator.Application.CS4"
25
CHAPTER 3: Scripting Illustrator
➤
Working with objects
26
Use the New operator if you added a reference to the Illustrator type library to the project. For example,
the following line creates a new reference to the Application object:
Set appRef = New Illustrator.Application
Quitting Illustrator
AppleScript
Use the quit command:
tell application "Adobe Illustrator"
quit
end tell
JavaScript
Use the app.quit() method:
app.quit()
VBScript
Use the Application object’s Quit method:
Set appRef = CreateObject("Illustrator.Application")
appRef.Quit
Working with objects
Getting the frontmost document or layer
To refer to the selected document, use the application object’s current document property in
AppleScript or the active document property in JavaScript or VBScript. Similarly, you can use the
document object’s current layer or active layer property to refer to the selected layer.
There are other types of “active” or “current” object properties, like active dataset or active view. For
details, see the Adobe Illustrator CS4 Scripting Reference for your language.
Creating new objects
Several objects (besides the application object itself ) cannot be obtained from containers or parent
objects. Your script must create these objects directly.

The file and folder objects are Adobe ExtendScript devices designed to provide platform-independent
access to the underlying file system. For information on using these objects, see JavaScript Tools Guide.
For information on creating an object explicitly, see the chapter for your scripting language.
Collection objects
Most collection objects must be obtained from a container. For example, a path items collection object
can be contained by a document object or a layer object; to obtain an object in a path items collection,
refer to either containing of these objects. For example, see the language-specific sections below.
AppleScript
To refer to a path items object in a document:
path item 1 in document 1
To refer to a path items object in a layer:
path item 1 in layer 1 in document 1
JavaScript
To refer to a path items object in a document:
documents[0].pathItems[1]
To refer to a path items object in a layer:
documents[0].layers[0].pathItems[0]
CHAPTER 3: Scripting Illustrator
Working with objects
28
VBScript
To refer to a path items object in a document:
Documents(1).PathItems(1)
To refer to a path items object in a layer:
Documents(1).Layers(1).PathItems(1)
For more examples of collection-item containers, see the document object Elements table in Adobe
Illustrator CS4 Scripting Reference: AppleScript or the Properties table in Adobe Illustrator CS4 Scripting
Reference: JavaScript or Adobe Illustrator CS4 Scripting Reference: VBScript. A diagram of the Illustrator CS4
object model is in “The Illustrator Scripting Object Model” on page 17.
Selected objects
Sometimes, you want to write scripts that act on the currently selected object or objects. For example, you
might want to apply formatting to selected text or change a selected path’s shape.
Selecting text
To select text, use the select command or method of the text range object.
Selecting art items
You can select an art object (like graph items, mesh items, raster items, and symbol items) by setting its
selected property to true. (In AppleScript, selected is a property of the page items object.)
Referring to selected art items
To refer to all currently selected objects in a document, use the document object’s selection property. To
work with the objects in the selection array, you must determine their type, so you will know which
properties and methods or commands you can use with them. In JavaScript and VBScript, each artwork
object type has a read-only typename property that you can use to determine the object’s type. In
AppleScript, use the class property.
Notes on renaming objects stored in the application’s panels
Several objects can be renamed; that is, their name property is writeable. The following types of objects can
be sorted alphabetically in the corresponding Illustrator panel. If a script modifies the name of such an
object, references to that object by index can become invalid.
Brush
Gradient
Graphic Style
Pattern
Swatch
Symbol
Variable
CHAPTER 3: Scripting Illustrator
Measurement units
29
Measurement units
Illustrator uses points as the unit of measurement for almost all distances. One inch equals 72 points. The
exception is values for properties like kerning, tracking, and the aki properties (used for Japanese text
composition), which use em units. (See “Em space units” on page 29.)
Illustrator uses points when communicating with your scripts regardless of the current ruler units. If your
script depends on adding, subtracting, multiplying, or dividing specific measurement values for units
other than points, it must perform any unit conversions needed to represent your measurements as
points. For example, to use inches for coordinates or measurement units, you must multiply all inch values
by 72 when entering the values in your script.
The following table shows conversion formulas for various units of measurement:
Unit
Conversion formula
centimeters
28.346 points = 1 centimeter
inches
72 points = 1 inch
millimeters
2.834645 points = 1 millimeter
picas
12 points = 1 pica
Qs
0.709 point = 1 Q (1 Q equals 0.23 millimeter)
JavaScript provides the UnitValue object type, which offers unit-conversion utilities. For details, see
JavaScript Tools Guide.
Em space units
Values that use em units instead of points are measured in thousandths of an em.
An em is proportional to the current font size. For example, in a 6-point font, 1 em equals 6 points; in a
10-point font, 1 em equals 10 points. In a 10-point font, a kerning value of 20 em units is equivalent to:
(20 units x 10 points) / 1000 units/em = 0.2 points
Page-item positioning and dimensions
Illustrator uses simple, two-dimensional geometry in the form of points to record the position of
page item objects in a document. Every page item object in a document has a position property that
defines a fixed point as a pair of page coordinates in the format [x, y]. The fixed point is the top-left corner
of the object’s bounding box.
For information on the types of objects that comprise the page items collection, see “The artwork tree” on
page 19.
A point is designated by a pair of coordinates:
➤
The horizontal position, x
➤
The vertical position, y
CHAPTER 3: Scripting Illustrator
Page-item positioning and dimensions
30
You can see these coordinates in the Info panel when you select or create an object in Illustrator.
The default ruler origin point (0, 0) for coordinate numbering in Illustrator is the lower-left corner of the
document. (ruler origin is a property of the document object) On the horizontal axis, coordinates to the
right of the ruler’s zero point are positive numbers. On the vertical axis, coordinates above the zero point
are positive.
The default page origin property of a document object defines the lower-left corner of the printable
region of the document as a fixed point.
Also, each page item object has width and height properties. The maximum value allowed for the width
or height of a page item is 16348 points.
Art item bounds
Every page item object has three properties that use fixed rectangles to describe the object’s overall
extent:
➤
The geometric bounds of a page item are the rectangular dimensions of the object’s bounding box,
excluding stroke width.
➤
The visible bounds of a page item are the dimensions of the object, including any stroke widths.
➤
The control bounds define the rectangular dimensions of the object, including in and out control
points.
The following figure illustrates these properties, using JavaScript naming conventions.
CHAPTER 3: Scripting Illustrator
Paths and shapes
31
Paths and shapes
Paths are represented in the Illustrator DOM by the path item object. Path items include all artwork that
contains paths, such as rectangles, ellipses, and polygons, as well as freeform paths.
A freeform path consists of a series of path points. A path point can be specified in two ways:
➤
As an array of x and y page coordinates.
➤
As a path point object, which defines an anchor point and two direction points or handles that define
the path segment’s curve:
For details, samples, and information on creating shapes, see the chapter for your scripting language.
User-interaction levels
When user feedback is required, an application typically presents a dialog. This is called user interaction. It
is useful and expected when you are directly interacting with the application; however, when a script is
interacting with an application, a dialog brings the execution of the script to a halt until the dialog is
dismissed. This can be a serious problem in an automation environment, where there is no one present to
deal with dialogs.
The application object contains a user interaction level property that allows you to control the level
of interaction allowed during script execution. You can suppress interaction in an automation
environment or allow some interaction where scripts are being used in a more interactive fashion.
AppleScript
Using AppleScript, it is possible to send commands from one machine to another, so additional types of
interaction are possible. In AppleScript:, there are four possible values for the user interaction level
property:
Property Value
Result
never interact
No interaction is allowed.
interact with self
Interact only with scripts executed from the Scripts menu (File > Scripts).
interact with local
Interact with scripts executed on the local machine (including self ).
interact with all
Interact with all scripts.
CHAPTER 3: Scripting Illustrator
Printing Illustrator documents
32
The four values allow you to control interaction based on the source of the script commands. For example,
if the application is acting as a server for remote users, it would be difficult for a remote user to dismiss a
dialog, but it would be no problem for someone sitting in front of the machine. In this case, an interaction
level of interact with local would prevent dialogs from halting remote scripts but would allow dialogs to be
presented for local scripts.
JavaScript
In JavaScript, there are two possible values for the app.userInteractionLevel property:
Property Value
Result
DISPLAYALERTS
Interaction is allowed.
DONTDISPLAYALERTS
No interaction is allowed.
VBScript
In VBScript, there are two possible values for the UserInteractionLevel property of the Application
object:
Property Value
Result
aiDisplayAlerts
Interaction is allowed.
aiDontDisplayAlerts
No interaction is allowed.
Printing Illustrator documents
Using the print options scripting feature, you can capture and automate parts of your print workflow.
Scripting exposes the full capabilities of Illustrator printing, some of which may not be accessible through
the application’s user interface.
Illustrator supports at most one print session at a time, because of limits in the current printing
architecture.
The document object’s print command or method takes one optional parameter, which allows you to
specify a print options object.
The print options object allows you to define print settings like PPD, PostScript options, paper options,
and color-management options. The print options object also has a print preset property, which
allows you to specify a preset to define your print job.
When defining the properties of a print options object, you can find out which printers, PPDs, print
presets, and other items are available by using the application object’s read-only “list” properties, such
as the printer list, PPD file list, and print presets list properties.

Scripting with AppleScript
This chapter uses script examples and explanations to help you to become familiar with Illustrator
scripting using AppleScript.
For more information
Several extended sample scripts are in the :Scripting:Sample Scripts folder in your Illustrator CS4
installation directory.
For information about individual classes, objects, properties, commands, and parameters, as well as script
samples that demonstrate how to use many of these items, see Adobe Illustrator CS4 Scripting Reference:
AppleScript, in the :Scripting:Documentation folder in your Illustrator CS4 installation directory. You
also can view the Illustrator CS4 dictionary from the Script Editor application;see “Viewing the AppleScript
object model” on page 8.
If you do not understand the concepts and terms used in this chapter, read Adobe Introduction to Scripting.
Your first Illustrator script
The traditional first project in any programming language is displaying the message “Hello World!” In this
example, you create a new Illustrator document, then add a text frame containing this message. Follow
these steps:
1. Open Script Editor.
In a default Mac OS installation, Script Editor is in Applications:AppleScript:Script Editor. If you
cannot find the Script Editor application, you must reinstall it from your Mac OS system CD.
2. Enter the following script.
--Send the following commands to Illustrator
tell application "Adobe Illustrator"
--Create a new document
set docRef to make new document
--Create a new text frame with the string "Hello World"
set textRef to make new text frame in docRef
with properties {contents: "Hello World!", position:{200, 200}}
end tell
3. In the Script Editor toolbar, click Run.
TIP: To add the script to the Illustrator Scripts menu (File > Scripts), save the script in the Scripts folder. The
script will appear on the menu the next time you start Illustrator. For details, see “Installing scripts in the
Scripts menu” on page 10.
33
CHAPTER 4: Scripting with AppleScript
Object references
34
Adding features to “Hello World”
Next, we create a new script that makes changes to the Illustrator document you created with your first
script. Our second script demonstrates how to:
➤
Get the active document.
➤
Get the width of the active document.
➤
Resize the text frame to match the document’s width.
If you already closed the Illustrator document, run your first script again to create a new document.
Follow these steps:
1. In Script Editor, choose File > New to create a new script.
2. Enter the following code:
tell application "Adobe Illustrator"
-- current document is always the active document
set docRef to the current document
set docWidth to the width of docRef
-- resize the text frame to match the page width
set width of text frame 1 of docRef to docWidth
-- alternatively, one can reference the item directly, as follows:
set width of text frame 1 of current document to docWidth
end tell
3. Run the script.
Object references
In AppleScript, Illustrator returns object references by index position or name. For example, this is a
reference to the first path in layer 2:
path item 1 of layer 2 of document 1
An object’s index position may change when other objects are created or deleted. For example, when a
new path item is created on layer 2, the new path item becomes path item 1 of layer 2 of document 1.
This new object displaces the original path item, forcing the original to index position 2; therefore, any
references made to path item 1 of layer 2 of document 1 refer to the new object. This method of
applying index numbers assures that lowest index number refers to the object that was worked on most
recently.
Consider the following sample script:
-- Make 2 new objects and try to select both
tell application "Adobe Illustrator"
set newDocument to make new document
set rectPath to make new rectangle in newDocument
set starPath to make new star in newDocument
set selection of newDocument to {rectPath, starPath}
end tell
This script does not select both the rectangle and the star, as intended; instead, it selects only the star. Try
running the script with the Event Log window open, to observe the references returned from Illustrator for
CHAPTER 4: Scripting with AppleScript
Object references
35
each consecutive make command. (Choose Event Log at the bottom of the Script Editor window.) Notice
that both commands return the same object reference: path item 1 of layer 1 of document 1; therefore,
the last line resolves to:
set selection of document 1 to {path item 1 of layer 1 of document 1,
path item 1 of layer 1 of document 1}
A better approach is to reference the objects by name:
tell application "Adobe Illustrator"
set newDocument to make new document
make new rectangle in newDocument with properties {name:"rectangle"}
make new star in newDocument with properties {name:"star"}
set selection of newDocument to
{path item "rectangle" of newDocument,
path item "star" of newDocument}
end tell
This example illustrates the need to uniquely identify objects in AppleScript scripts. We recommend that
you assign names or variables to objects you need to access at a later time, as there is no guarantee you
are accessing the objects you expect when accessing them by index.
Obtaining objects from documents and layers
This script references an object as part of a document:
-- Get reference for first page item of document 1
tell application "Adobe Illustrator"
set pageItemRef to page item 1 of document 1
end tell
In the following script, the pageItemRef variable does not necessarily refer to the same object as in the
previous script, because this script includes a reference to a layer:
-- Get reference for first page item of layer 1 of document 1
tell application "Adobe Illustrator"
set pageItemRef to page item 1 of layer 1 of document 1
end tell
Creating new objects
To create a new object in AppleScript, use the make command.
Working with selections
When the user makes a selection in a document, the selected objects are stored in the document’s
selection property. To access all selected objects in the active document:
tell application "Adobe Illustrator"
set myDoc to current document
set selectedObjects to selection of myDoc
end tell
CHAPTER 4: Scripting with AppleScript
Working with text frames
36
Depending on what is selected, the selection property value can be an array of any type of art objects.
To get or manipulate the properties of the selected art items, you must retrieve the individual items in the
array. To find out an object’s type, use the class property.
The following sample gets the first object in the array, then displays the object’s type:
tell application "Adobe Illustrator"
set myDoc to current document
set selectedObjects to selection of myDoc
set topObject to item 1 of selectedObjects
display dialog (class of topObject)
end tell
The first object in a selection array is the selected object that was last added to the page, not the last object
selected.
Selecting artwork objects
To select an art object, the object’s selected property.
Working with text frames
To create a text frame of a specific type in AppleScript, use the kind property of the text frame object:
set myRect to make new rectangle in current document with properties
{position:{100, 700}, height:100, width:100}
set myAreaText to make new text frame in current document with properties
{kind:point text,contents:"Text Frame 1"}
Threaded frames
As in the Illustrator application, you can thread area text frames or path text frames.
To thread existing text frames, use the next frame or previous frame property of the text frame object.
When copying the following script to your script editor, place the value of the contents property on one
line. The long-line character (¬) is not valid within a string value.
tell application "Adobe Illustrator"
make new document
make new rectangle in current document with properties
{position:{100, 500}, height:100, width:100}
make new text frame in current document with properties
{kind:area text, text path:the result, name:"tf1",
contents:"This is two text frames linked together as one story, with
text flowing from the first to the last. First frame content. "}
make new rectangle in current document with properties
{position:{300, 700}, height:100, width:100}
make new text frame in current document with properties
{kind:area text, text path:the result, name:"tf2",
contents:"Second frame content." }
--use the next frame property to thread the frames
set next frame of text frame "tf1" of current document to
text frame "tf2" of current document
redraw
end tell
CHAPTER 4: Scripting with AppleScript
Creating paths and shapes
37
Threaded frames make one story object
Threaded frames make a single story object. To observe this, run the following AppleScript after running
the script in “Threaded frames” on page 36.
display dialog ("There are " & (count(text frames of current document)) & " text frames.")
display dialog("There are " & (count(stories of current document)) & " stories.")
Creating paths and shapes
This section explains how to create items that contain paths.
Paths
To create line or a freeform path, specify a series of path points, as a series of x-y coordinates or path point
objects.
Using x-y coordinates limits the path to straight segments. To created a curved path, you must create
path point objects. A path can comprise a combination of page coordinates and path point objects.
Specifying a series of x-y coordinates
To specify a path using page-coordinate pairs, use the entire path property of the path items object.
The following script specifies three pairs of x-y coordinates, to create a path with three points:
tell application "Adobe Illustrator"
set docRef to make new document
-- set stroked to true so we can see the path
set lineRef to make new path item in docRef with properties {stroked:true}
set entire path of lineRef to {{220, 475},{200, 300},{375, 300}}
end tell
Using path point objects
To create a path point object, you must define three values for the point.
➤
A fixed anchor point, which is the point on the path.
➤
A pair of direction points—left direction and right direction—which allow you to control the
path segment’s curve.
You define each property as an array of page coordinates in the format [x, y]:
➤
If all three properties of a path point object have the same coordinates, and the properties of the next
path point in the line are equal to each other, you create a straight-line segment.
➤
If two or more properties in a path point object have different values, the segment connected to the
point is curved.
To create a path or add points to an existing path using path point objects, create a path item object,
then add the path points as child objects in the path item:
CHAPTER 4: Scripting with AppleScript
Creating paths and shapes
38
tell application "Adobe Illustrator"
set docRef to make new document
-- set stroked to true so we can see the path
set lineRef to make new path item in docRef with properties {stroked:true}
--giving the direction points the same value as the
--anchor point creates a straight line segment
set newPoint to make new path point of lineRef with properties
{anchor:{220, 475},left direction:{220, 475},right direction:{220, 475},
point type:corner}
set newPoint2 to make new path point of lineRef with properties
{anchor:{375, 300},left direction:{375, 300},right direction:{375, 300},
point type:corner}
--giving the direction points the different values
--creates a curve
set newPoint3 to make new path point of lineRef with properties
{anchor:{220, 300},left direction:{180, 260},right direction:{240, 320},
point type:corner}
end tell
Combining path point types
The following script sample creates a path with three points, by combining the entire path property with a
path point object:
tell application "Adobe Illustrator"
set docRef to make new document
-- set stroked to true so we can see the path
set lineRef to make new path item in docRef with properties {stroked:true}
set entire path of lineRef to {{220, 475},{375, 300}}
set newPoint to make new path point of lineRef with properties
{anchor:{220, 300},left direction:{180, 260},right direction:{240, 320},
point type:corner}
end tell
Shapes
To create a shape, you use the object that corresponds to the shape’s name (like ellipse, rectangle, or
polygon), and use the object’s properties to specify the shape’s position, size, and other information like
the number of sides in a polygon.
Remember:
➤
The scripting engine processes all measurements and page coordinates as points. For details, see
“Measurement units” on page 29.
➤
x and y coordinates are measured from the bottom-left corner of the document, as indicated in the
Info panel in the Illustrator application. For details, see “Page-item positioning and dimensions” on
page 29.
CHAPTER 4: Scripting with AppleScript
Creating paths and shapes
39
Write-once access
Properties for path-item shapes use the “write-once” access status, which indicates that the property is
writeable only when the object is created. For existing path-item objects, the properties are read-only
properties whose values cannot be changed.
Creating a rectangle
Consider the following sample:
tell application "Adobe Illustrator"
set docRef to make new document
set rectRef to make new rectangle in docRef with properties
{bounds:{288, 360, 72, 144}}
end tell
The sample creates a rectangle with these properties:
➤
The top-right corner of the of the rectangle is inset 4 inches (288 points) from the bottom of the page
and 5 inches (360 points) from the left edge of the page.
➤
The lower-left corner of the rectangle is inset 1 inch (72 points) from the left edge of the page and
2 inches (144 points) from the bottom of the page.
Creating a polygon
Consider the following sample:
tell application "Adobe Illustrator"
set docRef to make new document
set pathRef to make new polygon in docRef with properties
{center point:{144, 288},sides:7,radius:72.0}
end tell
The sample creates a polygon with these properties:
➤
The center point of the object is inset is 2 inches (144 points) on the horizontal axis and 4 inches
(288 points) on the vertical axis.
➤
The polygon has 7 sides.
➤
The length of the radius from the center point to each corner is 1 inch (72 points).

Scripting with JavaScript
This chapter uses script examples and explanations to help you to become familiar with Illustrator
scripting using JavaScript.
For more information
Several extended sample scripts are in the /Scripting/Sample Scripts folder in your Illustrator CS4
installation directory.
For information about individual classes, objects, properties, methods, and parameters, as well as script
samples that demonstrate how to use many of these items, see Adobe Illustrator CS4 Scripting Reference:
JavaScript, in the /Scripting/Documentation folder in your Illustrator CS4 installation directory. You also
can use the Illustrator dictionary, which you access from the Object Model Viewer in the ESTK. For
information on using the ExtendScript Toolkit and the Object Model Viewer, see “Viewing the JavaScript
object model” on page 8 or JavaScript Tools Guide.
If you do not understand the concepts and terms used in this chapter, read Adobe Introduction to Scripting.
Your first Illustrator script
The traditional first project in any programming language is displaying the message “Hello World!” In this
example, you create a new Illustrator document, then add a text frame containing this message. Follow
these steps:
1. Using any text editor (including Adobe InDesign® or the ESTK), enter the following text:
//Hello World!
var myDocument = app.documents.add();
//Create a new text frame and assign it to the variable "myTextFrame"
var myTextFrame = myDocument.textFrames.add();
// Set the contents and position of the text frame
myTextFrame.position = [200,200];
myTextFrame.contents = "Hello World!"
For information on locating the ExtendScript Toolkit, see “Viewing the JavaScript object model” on
page 8.
2. To test the script, do either of the following:
➣
If you are using the ESTK, select Adobe Illustrator CS4 from the drop-down list in the upper-left
corner, select Yes to start Illustrator, then choose Debug > Run in the ESTK to run the script.
➣
If you are using a different text editor than the ESTK, save the file as text-only in a folder of your
choice, using the file extension .jsx, then start Illustrator. In Illustrator, choose File > Scripts >
Other Scripts, and navigate to and run your script file.
TIP: To add the script to the Illustrator Scripts menu (File > Scripts), save the script in the Scripts folder. The
script will appear on the menu the next time you start Illustrator. For details, see “Installing scripts in the
Scripts menu” on page 10.

CHAPTER 5: Scripting with JavaScript
Working with methods in JavaScript
41
Adding features to “Hello World”
Next, we create a new script that makes changes to the Illustrator document you created with your first
script. Our second script demonstrates how to:
➤
Get the active document.
➤
Get the width of the active document.
➤
Resize the text frame to match the document’s width.
If you already closed the Illustrator document, run your first script again to create a new document, before
proceeding with this exercise.
Follow these steps:
1. Choose File > New in your text editor, to create a new script.
2. Enter the following code:
var docRef = app.activeDocument;
var docWidth = docRef.width
var frameRef = docRef.textFrames[0]
frameRef.width = docWidth
3. Run the script.
Working with methods in JavaScript
When you work with methods that have multiple parameters, you may omit optional parameters at the
end of the parameter list, but you may not omit parameters in the middle of the list. If you do not want to
specify a particular parameter in the middle of the list, you must insert the value undefined to use the
parameter’s default value. For example, the following definition describes the rotate() method for an art
object.
rotate
(angle
[,changePositions]
[,changeFillPatterns]
[,changeFillGradients]
[,changeStrokePattern]
[,rotateAbout])
In the definition, taken from Adobe Illustrator CS4 Scripting Reference: JavaScript, optional parameters are
enclosed in square brackets ([]).
To rotate the object 30 degrees and change the fillGradients, you would use the following script
statement:
myObject.rotate(30, undefined, undefined, true);
You need to specify undefined for the changePositions and changeFillPatterns parameters. You do
not have to specify anything for the two optional parameters following changeFillGradients, since they
are at the end of the parameter list.
CHAPTER 5: Scripting with JavaScript
Accessing and referencing objects
42
Accessing and referencing objects
When you write a script, you must first decide which file, or document, the script should act on. Through
the application object, the script can create a new document, open an existing document, or act on a
document that is already open.
The script can create new objects in the document, operate on objects that the user selected, or operate
on objects in one of the object collections. The following sections illustrate various techniques for
accessing, referencing, and manipulating Illustrator objects.
Referencing the application object
To obtain a reference to a specific object, you need to navigate the containment hierarchy. Because all
JavaScript scripts are executed from within the Illustrator application, however, a specific reference to the
application object is not required. For example, to assign the active document in Illustrator to the
variable frontMostDocument, you could reference the activeDocument property of the application
object, as follows:
var frontMostDocument = activeDocument;
It is permissible to use the application object in a reference. To reference the application object, use
the app global variable. The following two statements appear identical to the JavaScript engine:
var frontMostDocument = activeDocument;
var frontMostDocument = app.activeDocument;
Accessing objects in collections
All open documents, as well as the objects in a document, are collected into collection objects for the
object type. A collection object contains an array of the objects that you can access by index or name. The
collection object takes the plural form of the object name. For example, the collection object for the
document object is documents.
The following script sample gets all graphic style objects in the graphic styles collection; that is, it
gets all graphic styles available to the active document:
var myStyles = app.activeDocument.graphicStyles;
All numeric collection references in JavaScript are zero-based: the first object in the collection has the
index [0].
As a rule, JavaScript index numbers do not shift when you add an object to a collection. There is one
exception: documents[0] is always the active or frontmost document.
To access the first style in a graphic styles collection, you can use the variable declared in the previous
script sample, or you can use the containment hierarchy to refer to the collection:
➤
Using the myStyles variable:
var firstStyle = myStyles[0];
➤
Using the containment hierarchy:
var firstStyle = app.activeDocument.graphicStyles[0];
CHAPTER 5: Scripting with JavaScript
Accessing and referencing objects
43
The following statements assign the name of the first graphic style in the collection to a variable. You can
use these statements interchangeably.
var styleName = myStyles[0].name
var styleName = firstStyle.name
var styleName = app.activeDocument.graphicStyles[0].name
To get the total number of objects in a collection, use the length property:
alert ( myStyles.length );
The index of the last graphic style in the collection is myStyles.length-1 (-1 because the collection
starts the index count at 0 and the length property counts from 1):
var lastStyle = myStyles[ myStyles.length - 1 ];
Note that an expression representing the index value is enclosed in square brackets ([]) as well as quotes.
If you know the name of an object, you can access the object in the collections using the name surrounded
by square brackets; for example:
var getStyle = myStyles[Ice Type];
Each element in the collection is an object of the desired type, and you can access its properties through
the collection. For example, to get an object’s name, use the name property:
var styleName = app.activeDocument.graphicStyles[0].name;
To apply lastStyle to the first pageItem in the document, use its applyTo() method:
lastStyle.applyTo( app.activeDocument.pageItems[0] );
Creating new objects
You can use a script to create new objects. To create objects that are available from collection objects, or
containers, use the container object’s add() method:
var myDoc = app.documents.add()
var myLayer = myDoc.layers.add()
Some object types are not available from containers. To create an object of this type, define a variable,
then use the new operator with an object constructor to assign an object as the value. For example, to
create a new CMYKColor object using the variable name myColor:
var myColor = new CMYKColor()
CHAPTER 5: Scripting with JavaScript
Working with text frames
44
Working with selections
When the user makes a selection in a document, the selected objects are stored in the document’s
selection property. To access all selected objects in the active document:
var selectedObjects = app.activeDocument.selection;
The selection property value can be an array of any type of art objects, depending on what types of
objects are selected. To get or manipulate the properties of the selected art items, you must retrieve the
individual items in the array. To find out an object’s type, use the typename property.
The following sample gets the first object in the array, then displays the object’s type:
var topObject = app.activeDocument.selection[0];
alert(topObject.typename)
The first object in a selection array is the selected object that was last added to the page, not the last object
selected.
Selecting artwork objects
To select an art object, use the object’s selected property.
Working with text frames
To create a text frame of a specific type in JavaScript, use the textFrames method whose name
corresponds to the text frame’s type; for example:
var rectRef = docRef.pathItems.rectangle(700, 50, 100, 100);
//use the areaText method to create the text frame
var areaTextRef = docRef.textFrames.areaText(rectRef);
Threaded frames
As in the Illustrator application, you can thread area text frames or path text frames.
To thread existing text frames, use the nextFrame or previousFrame property of the text frame object.
When copying the following script to the ESTK, place the value of the contents property on one line.
var
var
var
var
var
myDoc = documents.add();
myPathItem1 = myDoc.pathItems.rectangle(244, 64, 82, 76);
myTextFrame1 = myDoc.textFrames.areaText(myPathItem1);
myPathItem2 = myDoc.pathItems.rectangle(144, 144, 42, 116);
myTextFrame2 = myDoc.textFrames.areaText(myPathItem2);
// use the nextFrame property to thread the text frames
myTextFrame1.nextFrame = myTextFrame2;
var sText = "This is two text frames linked together as one story, with text
flowing from the first to the last. This is two text frames linked together as one
story, with text flowing from the first to the last. This is two text frames linked
together as one story. ";
myTextFrame1.contents = sText;
redraw();
CHAPTER 5: Scripting with JavaScript
Creating paths and shapes
45
Threaded frames make a single story object
Threaded frames make a single story object. To observe this, run the following JavaScript after running
the script in “Threaded frames” on page 44.
var myDoc = app.activeDocument
alert("There are " + myDoc.textFrames.length + " text frames.")
alert("There are " + myDoc.stories.length + " stories.")
Creating paths and shapes
This section explains how to create items that contain paths.
Paths
To create a freeform path, specify a series of path points, as a series of x-y coordinates or pathPoint
objects.
Using x-y coordinates limits the path to straight segments. To created a curved path, you must create
pathPoint objects. Your path can comprise a combination of page coordinates and pathPoint objects.
Specifying a series of x-y coordinates
To specify a path using page coordinate pairs, use the setEntirePath() method of the pathItems object.
The following script specifies three pairs of x-y coordinates, to create a path with three points:
var myDoc = app.activeDocument;
var myLine = myDoc.pathItems.add();
//set stroked to true so we can see the path
myLine.stroked = true;
myLine.setEntirePath([[220, 475], [375, 300], [200, 300]]);
Using pathPoint objects
When you create a pathPoint object, you define three values for the point:
➤
A fixed anchor point, which is the point on the path.
➤
A pair of direction points—left direction and right direction—which allow you to control the
path segment’s curve.
You define each property as an array of page coordinates in the format [x, y].
➤
If all three properties of a pathPoint object have the same coordinates, and the properties of the next
pathPoint in the line are equal to each other, you create a straight-line segment.
➤
If two or more properties in a pathPoint object hold different values, the segment connected to the
point is curved.
To create a path or add points to an existing path using pathPoint objects, create a pathItem object, then
add the path points as child objects in the pathItem:
CHAPTER 5: Scripting with JavaScript
Creating paths and shapes
46
var myDoc = app.activeDocument;
var myLine = myDoc.pathItems.add();
//set stroked to true so we can see the path
myLine.stroked = true;
var newPoint = myLine.pathPoints.add();
newPoint.anchor = [220, 475];
//giving the direction points the same value as the
//anchor point creates a straight line segment
newPoint.leftDirection = newPoint.anchor;
newPoint.rightDirection = newPoint.anchor;
newPoint.pointType = PointType.CORNER;
var newPoint1 = myLine.pathPoints.add();
newPoint1.anchor = [375, 300];
newPoint1.leftDirection = newPoint1.anchor;
newPoint1.rightDirection = newPoint1.anchor;
newPoint1.pointType = PointType.CORNER;
var newPoint2 = myLine.pathPoints.add();
newPoint2.anchor = [220, 300];
//giving the direction points different values
//than the anchor point creates a curve
newPoint2.leftDirection =[180, 260];
newPoint2.rightDirection = [240, 320];
newPoint2.pointType = PointType.CORNER;
Combining path point types
The following script sample creates a path with three points:
var myDoc = app.activeDocument;
var myLine = myDoc.pathItems.add();
myLine.stroked = true;
myLine.setEntirePath( [[220, 475], [375, 300]]);
// Append another point to the line
var newPoint = myDoc.myLine.pathPoints.add();
newPoint.anchor = [220, 300];
newPoint.leftDirection = newPoint.anchor;
newPoint.rightDirection = newPoint.anchor;
newPoint.pointType = PointType.CORNER;
Shapes
To create a shape, use the pathItems method that corresponds to the shape’s name (like ellipse,
rectangle, or polygon), and use the parameters to specify shape’s position, size, and other information
like the number of sides in a polygon.
Remember:
➤
All measurements and page coordinates are processed as points by the scripting engine. For details,
see “Measurement units” on page 29.
➤
x and y coordinates are measured from the bottom-left corner of the document, as indicated in the
Info panel in the Illustrator application. For details, see “Page-item positioning and dimensions” on
page 29.
CHAPTER 5: Scripting with JavaScript
Creating paths and shapes
47
Creating a rectangle
Consider the following sample
var myDocument = app.documents.add()
var artLayer = myDocument.layers.add()
var rect = artLayer.pathItems.rectangle( 144, 144, 72, 216 );
The sample uses the pathItems object’s rectangle() method to create a rectangle with these properties:
➤
The top of the rectangle is 2 inches (144 points) from the bottom edge of the page.
➤
The left edge is 2 inches (144 points) from the left edge of the page.
➤
The rectangle is 1 inch (72 points) wide and 3 inches (216 points) long.
Creating a polygon
Consider the following sample:
var myDocument = app.documents.add()
var artLayer = myDocument.layers.add()
var poly = artLayer.pathItems.polygon( 144, 288, 72.0, 7 );
The sample uses the polygon() method to create a polygon with these properties:
➤
The center point of the object is inset is 2 inches (144 points) on the horizontal axis and 4 inches (288
points) on the vertical axis.
➤
The length of the radius from the center point to each corner is 1 inch (72 points).
➤
The polygon has 7 sides.

Scripting with VBScript
This chapter uses script examples and explanations to help you to become familiar with Illustrator
scripting using VBScript.
For more information
Several extended sample scripts are in the /Scripting/Sample Scripts folder in your Illustrator CS4
installation directory.
For information about individual classes, objects, properties, methods, and parameters, as well as script
samples that demonstrate how to use many of these items, see Adobe Illustrator CS Scripting Reference:
VBScript, in the /Scripting/Documentation folder in your Illustrator CS4 installation directory. You also
can view the Illustrator CS4 type library from most VBScript editors or any Microsoft Office application; see
“Viewing the VBScript object model” on page 9.
If you do not understand the concepts and terms used in this chapter, read Adobe Introduction to Scripting.
Your first Illustrator script
The traditional first project in any programming language is displaying the message “Hello World!” Follow
these steps:
1. Start any text editor (for example, Notepad).
2. Type the following code:
Rem Hello World
Set appRef = CreateObject("Illustrator.Application")
Rem Create a new document and assign it to a variable
Set documentRef = appRef.Documents.Add
Rem Create a new text frame item and assign it to a variable
Set sampleText = documentRef.TextFrames.Add
Rem Set the contents and position of the TextFrame
sampleText.Position = Array(200, 200)
sampleText.Contents = "Hello World!"
3. Save the file as text-only in a folder of your choice, using the file extension .vbs.
4. To test the script, do one of the following:
➣
Double-click the file.
➣
Start Illustrator, choose File > Scripts > Other Scripts, and navigate to and run your script file.
TIP: To add the script to the Illustrator Scripts menu (File > Scripts), save the script in the Scripts folder. The
script will appear on the menu the next time you start Illustrator. For details, see “Installing scripts in the
Scripts menu” on page 10. In general, when you launch a VBScript script from the Scripts menu, any
msgBox dialogs will not display correctly.
48
CHAPTER 6: Scripting with VBScript
Accessing and referencing objects
49
Adding features to “Hello World”
Next, we create a new script that makes changes to the Illustrator document you created with your first
script. The second script demonstrates how to:
➤
Get the active document.
➤
Get the width of the active document.
➤
Resize the text frame item to match the document’s width.
If you closed the Illustrator document without saving it, run your first script again to create a new
document.
Follow these steps:
1. Copy the following script into your text editor, and save the file.
Set appRef = CreateObject("Illustrator.Application")
'Get the active document
Set documentRef = appRef.ActiveDocument
Set sampleText = documentRef.TextFrames(1)
' Resize the TextFrame item to match the document width
sampleText.Width = documentRef.Width
sampleText.Left = 0
2. Run the script.
Accessing and referencing objects
When you write a script, you must first decide which file, or Document, the script should act on. Through
the Application object, the script can create a new document, open an existing document, or act on a
document that is already open.
The script can create new objects in the document, operate on objects that the user selected, or operate
on objects in one of the object collections. The following sections illustrate techniques for accessing,
referencing, and manipulating Illustrator objects.
Obtaining objects from collections
Generally, to obtain a reference to a specific object, you can navigate the containment hierarchy. For
example, to use the myPath variable to store a reference to the first PathItem in the second layer of the
active document:
Set myPath = appRef.ActiveDocument.Layers(2).PathItems(1)
The following scripts demonstrate how to reference an object as part of a document:
Set documentRef = appRef.ActiveDocument
Set pageItemRef = documentRef.PageItems(1)
CHAPTER 6: Scripting with VBScript
Accessing and referencing objects
50
In the script below, the variable pageItemRef will not necessarily refer to the same object as the above
script, since this script includes a reference to a layer:
Set documentRef = appRef.ActiveDocument
Set pageItemRef = documentRef.Layers(1).PageItems(1)
VBScript indexes start at 1 for object collections; however, VBScript allows you to specify whether array
indexes start at 1 or 0. For information on specifying the index start number for arrays, see any VBScript
textbook or tutorial.
Creating new objects
You can use a script to create new objects. To create objects that are available from collection objects, use
the collection object’s Add method:
Set myDoc = appRef.Documents.Add()
Set myLayer = myDoc.Layers.Add()
Some collection objects do not have an Add method. To create an object of this type, define a variable and
use the CreateObject method. For example, the following code creates a new CMYKColor object using
the variable name newColor:
Set newColor = CreateObject ("Illustrator.CMYKColor")
Working with selections
When the user makes a selection in a document, the selected objects are stored in the document’s
selection property. To access all selected objects in the active document:
Set appRef = CreateObject ("Illustrator.Application")
Set documentRef = appRef.ActiveDocument
selectedObjects = documentRef.Selection
Depending on what is selected, the selection property value can be an array of any type of art objects. To
get or manipulate the properties of the selected art items, you must retrieve the individual items in the
array. To find out an object’s type, use the typename property.
The following sample gets the first object in the array, then displays the object’s type:
Set appRef = CreateObject ("Illustrator.Application")
Set documentRef = appRef.ActiveDocument
selectedObjects = documentRef.Selection
Set topObject = selectedObjects(0)
MsgBox(topObject.Typename)
The MsgBox method does not display a dialog when the script is run from the Illustrator Scripts menu
(File > Scripts).
The first object in a selection array is the selected object that was last added to the page, not the last object
selected.
Selecting artwork objects
To select an artwork object, use the object’s Selected property.
CHAPTER 6: Scripting with VBScript
Working with text frames
51
Working with text frames
To create a text frame of a specific type in VBScript, use the TextFrames method that corresponds to the
type of frame you want to create:
Set rectRef = docRef.PathItems.Rectangle(700, 50, 100, 100)
' Use the AreaText method to create the text frame
Set areaTextRef = docRef.TextFrames.AreaText(rectRef)
Threaded frames
As in the Illustrator application, you can thread area path frames or path text frames.
To thread existing text frames, use the NextFrame or PreviousFrame property of the TextFrames object.
When copying the following script to a script or text editor, place the value of the Contents property on
one line. The long-line continuation character (_) is not valid when enclosed in a string.
Set
Set
Set
Set
appRef = CreateObject("Illustrator.Application")
myDoc = appRef.Documents.Add
myPathItem1 = myDoc.PathItems.Rectangle(244, 64, 82, 76)
myTextFrame1 = myDoc.TextFrames.AreaText(myPathItem1)
myTextFrame1.Contents = "This is two text frames linked together as one story, with
text flowing from the first to the last."
Set myPathItem2 = myDoc.PathItems.Rectangle(144, 144, 42, 116)
Set myTextFrame2 = myDoc.TextFrames.AreaText(myPathItem2)
'Use the NextFrame property to thread the frames
myTextFrame1.NextFrame = myTextFrame2
appRef.Redraw()
Threaded frames make a single story object
Threaded frames make a single story object. To observe this, run the following VBScript after running the
script in “Threaded frames” on page 51.
Set myDoc = appRef.ActiveDocument
myMsg = "alert(""There are " & CStr(myDoc.TextFrames.Count) & " text frames. "")"
appRef.DoJavaScript myMsg
myMsg = "alert(""There are " & CStr(myDoc.Stories.Count) & " storiess. "")"
appRef.DoJavaScript myMsg
Creating paths and shapes
This section explains how to create items that contain paths.
Paths
To create a freeform path, specify a series of path points, as a series of either x-y coordinates or PathPoint
objects.
CHAPTER 6: Scripting with VBScript
Creating paths and shapes
52
Using x-y coordinates limits the path to straight segments. To created a curved path, you must create
PathPoint objects. Your path can comprise a combination of page coordinates and PathPoint objects.
Specifying a series of x-y coordinates
To specify a path using page-coordinate pairs, use the SetEntirePath() method of the PathItems
object. The following script specifies three pairs of x-y coordinates, to create a path with three points:
Set appRef = CreateObject ("Illustrator.Application")
Set firstPath = appRef.ActiveDocument.PathItems.Add
firstPath.Stroked = True
firstPath.SetEntirePath(Array(Array(220, 475),Array(375, 300),Array(200, 300)))
Using path point objects
To create a PathPoint object, you must define three values for the point:
➤
A fixed anchor point, which is the point on the path.
➤
A pair of direction points—left direction and right direction—which allow you to control the
path segment’s curve.
You define each property as an array of page coordinates in the format (Array (x,y)).
➤
If all three properties of a PathPoint object have the same coordinates, and the properties of the next
PathPoint in the line are equal to each other, you create a straight-line segment.
➤
If two or more properties in a PathPoint object hold different values, the segment connected to the
point is curved.
To create a path or add points to an existing path using PathPoint objects, create a PathItem object, then
add the path points as child objects in the PathItem:
Set appRef = CreateObject ("Illustrator.Application")
Set firstPath = appRef.ActiveDocument.PathItems.Add
firstPath.Stroked = true
Set newPoint = firstPath.PathPoints.Add
'Using identical coordinates creates a straight segment
newPoint.Anchor = Array(75, 300)
newPoint.LeftDirection = Array(75, 300)
newPoint.RightDirection = Array(75, 300)
Set newPoint2 = firstPath.PathPoints.Add
newPoint2.Anchor = Array(175, 250)
newPoint2.LeftDirection = Array(175, 250)
newPoint2.RightDirection = Array(175, 250)
Set newPoint3 = firstPath.PathPoints.Add
'Using different coordinates creates a curve
newPoint3.Anchor = Array(275, 290)
newPoint3.LeftDirection = Array(135, 150)
newPoint3.RightDirection = Array(155, 150)
CHAPTER 6: Scripting with VBScript
Creating paths and shapes
53
Combining path-point types
The following script sample creates a path with three points:
Set appRef = CreateObject("Illustrator.Application")
Set myDoc = appRef.ActiveDocument
Set myLine = myDoc.PathItems.Add
myLine.Stroked = True
myLine.SetEntirePath( Array( Array(320, 475), Array(375, 300)))
' Append another point to the line
Set newPoint = myLine.PathPoints.Add
'Using identical coordinates creates a straight segment
newPoint.Anchor = Array(220, 300)
newPoint.LeftDirection = Array(220, 300)
newPoint.RightDirection = Array(220, 300)
Shapes
To create a shape, use the PathItems method that corresponds to the shape’s name (like ellipse,
rectangle, or polygon), and use parameters to specify the shape’s position, size, and other characteristics
like the number of sides in a polygon.
Remember:
➤
The scripting engine processes all measurements and page coordinates as points. For details, see
“Measurement units” on page 29.
➤
x and y coordinates are measured from the bottom-left corner of the document, as indicated in the
Info panel in the Illustrator application. For details, see “Page-item positioning and dimensions” on
page 29.
Creating a rectangle
Consider the following sample:
Set appRef = CreateObject("Illustrator.Application")
Set frontDocument = appRef.ActiveDocument
' Create a new rectangle with
' top = 144, left side = 144, width = 72, height = 144
Set newRectangle = frontDocument.PathItems.Rectangle(144,144,72,144)
The sample creates a rectangle with these properties:
➤
The top of the rectangle is 2 inches (144 points) from the bottom edge of the page.
➤
The left edge is 2 inches (144 points) from the left edge of the page.
➤
The rectangle is 1 inch (72 points) wide and 2 inches (144 points) long.
CHAPTER 6: Scripting with VBScript
Working with enumeration values

Creating a polygon
Consider the following sample:
Set appRef = CreateObject("Illustrator.Application")
Set frontDocument = appRef.ActiveDocument
' Create a new polygon with
' top = 144, left side = 288, width = 72, height = 144
Set newPolygon = frontDocument.PathItems.Polygon(144,288,72,7)
The sample creates a polygon with these properties:
➤
The center point of the object is inset 2 inches (144 points) on the horizontal axis and 4 inches
(288 points) on the vertical axis.
➤
The length of the radius from the center point to each corner is 1 inch (72 points).
➤
The polygon has 7 sides.
Working with enumeration values
Properties that use enumeration values in VBScript use a numeral rather than a text value. For example,
the Orientation property of the TextFrame object specifies whether text content in the text frame is
horizontal or vertical. The property uses the aiTextOrientation enumeration, which has two possible
values, aiHorizontal and aiVertical.
To find the numeral values of enumerations, use either of the following:
➤
The object browser in your scripting editor environment. See “Viewing the VBScript object model” on
page 9.
➤
The Adobe Illustrator CS4 Scripting Reference: VBScript, which lists the numeral values directly after the
constant value in the “Enumerations” chapter at the end of the book. The following example is from
that table:
Enumeration type
AiTextOrientation
Values
aiHorizontal = 0
aiVertical = 1
What it means
The orientation of text in a text frame
The following sample specifies vertical text orientation:
Set appRef = CreateObject ("Illustrator.Application")
Set docRef = appRef.Documents.Add
Set textRef = docRef.TextFrames.Add
textRef.Contents = "This is some text content."
textRef.Left = 50
textRef.Top = 700
textRef.Orientation = 1
Generally, it is considered good scripting practice to place the text value in a comment following the
numeral value, as in the following sample statement:
textRef.Orientation = 1 ' aiVertical
