Text Callout not working in acrobat javascript

Question

I'm trying to insert Text callout, however its not showing up. It only showing the annotation box without arrow pointer. Please refer the code mentioned below:

var annot = this.addAnnot({
        page: 0,
        type: "FreeText",
        intent: "FreeTextCallout",
        rect: [10, 10, 10, 10],
        richContents: spans
    });

Answer 1

You're missing the "callout" property. The callout property is an array of six numbers specifying a callout line attached to the free text annotation. The six numbers [ x1 y1 x2 y2 x3 y3 ] represent the starting, knee point, and ending coordinates of the line in default user space. See the graphic.
