After effect scripting set text bounds

[madhawap70708962]

I'm trying to generate text layers dinamically using a script.It works well.I coudn't find a way to contain the text without overflowing .As you can see in this image text is gone out of the composition view.

I trid to set a width but it doesn't work .Any idea about this.

var textLayer = comp.layers.addText(text);
textLayer.sourceRectAtTime(inPoint, false).width=1000;

This will adjust the font size to fit within a maximum width:

var text = "this is a long text testing scripting";
var comp = app.project.activeItem;
var maxWidth = comp.width;
var textLayer = comp.layers.addText(text);
var w = textLayer.sourceRectAtTime(textLayer.inPoint, false).width;
if (w > maxWidth){
	var sourceText = textLayer.text.sourceText;
	var textDoc = sourceText.value;
	textDoc.fontSize *= maxWidth/w;
	sourceText.setValue(textDoc);
}

You will have to create paragraph text, not line-based text. Otherwise you have to do your own calculations to adjust size or wrap lines around. The text bounding box has nothing to do with this.

You can also apply an expression to the layer scale, which scales the layer down when the source text goes beyond a certain size.

In the Community Library of Automation Blocks we have a tool which creates such expressions:
