Hi there!

We have an API for this coming in version 8.0 (will be released soon), but for now I found a little trick that should work for you.

The `pageInfo` object you pass in contains the width and height of the document, and the `fitText` function uses that width to know how far over to the right it is allowed to expand before it needs to break to the next line. By altering `pageInfo.width` we can trick the function into breaking into a new line before it actually needs to:

```javascript
const freeTextAnnot = new Annotations.FreeTextAnnotation();
freeTextAnnot.X = 100;
freeTextAnnot.Width = 100;
// ... other annot config

const pageInfo = doc.getPageInfo(pageNumber);
pageInfo.width = freeTextAnnot.X + freeTextAnnot.Width;
freeTextAnnot.fitText(pageInfo, pageMatrix, pageRotation);

```

This code will make sure the freeTextAnnot always maintains the width you set it to.

Let me know this goes!

Thanks,  
Logan
