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

2: The Illustrator Scripting Object Model

Text objects

Color objects

Your script can apply a color, pattern or gradient to a

path

item

object, using the

fill

color

strokecolor

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

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

➤
