Character Style Inherits Path Style

The CharacterStyle object inherits all properties of PathStyle, which means you can style a text range with all the same properties as you would use to style a path.

var position = new Point(100, 100);
var textItem = new PointText(position);
textItem.content = 'Roses are red.rViolets are blue.';

var redWord = textItem.range.words[2];
redWord.characterStyle.fillColor = '#ff0000';

var blueWord = textItem.range.words[5];
blueWord.characterStyle.fillColor = '#8F00FF';

Changing the Font of a Text Range

You can access the fonts installed on your computer through the app.fonts property. When you access app.fonts by font name, it returns an array of font weight objects which are also accessible by name.

You can change the font of a text range by passing a font family or font weight to its textRange.characterStyle.font property:

var position = new Point(100, 100);
var textItem = new PointText(position);
textItem.content = 'Helvetica and Times';

// The first word:
var hRange = textItem.range.words[0];
hRange.characterStyle.font = app.fonts['Helvetica']['Regular'];

// The third word:
var tRange = textItem.range.words[2];
tRange.characterStyle.font  = app.fonts['Times'];

Font Size

You can change the font size of a text range through its textRange.fontSize property:

var position = new Point(100, 100);
var textItem = new PointText(position);
textItem.content = 'LittlerandrLarge';

var littleRange = textItem.range.words[0];
littleRange.characterStyle.fontSize = 5;

var largeRange = textItem.range.words[2];
largeRange.characterStyle.fontSize = 15;
