CHAPTER 6: Scripting with VBScript Accessing and referencing objects 57

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.
