CHAPTER 3: Scripting Illustrator Paths and shapes 32

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:

X As an array of x and y page coordinates.

X 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
