CHAPTER 2: The Illustrator Scripting Object Model The artwork tree 20

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:

X The current selection, or art objects that the user selected in the document

X All contained art objects, called page items, that make up the artwork tree

X Art objects of particular types, like symbols and text frames

X All layers and the currently active layer

Document properties also tell you about the state of the document itself; for example:

X User settings for the document, such as ruler units

X Whether the document was saved since the last alteration of content

X The path of the associated file

The

document object’s methods allow your scripts to act on the document; for example:

X Save to an Illustrator file or save as the various supported file formats

X Activate or close a document

X 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:

X Whether the layer is visible or locked.

X The layer’s opacity (overall transparency) and z order position (position in the stacking order).

X 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:

X compound path item

X graph item

X group item

X legacy text item
