SetFormFieldIcon
Form fields
Description
Sets the icon of a button form field. To create an icon: add a new page to the document, set the size and draw images or text onto the page, and then capture the page using the CapturePage function. For a "down" or "rollover" icon to be displayed correctly the form field's hightlight mode must be set to "push", see the SetFormFieldHighlightMode function.
