Use this function to draw the visual appearance onto the page it is associated with. The form field will then be removed from the document and only it's appearance will remain - it will no longer be an interactive field.
If the field is flattened successfully the field index of subsequent form fields will be decreased by 1.
From version 9.11 this function no longer updates the form field's appearance stream before flattening. To update the appearance stream before flattening, use the UpdateAndFlattenFormField function or call UpdateAppearanceStream followed by a call to this function.
