Parameter Requirements: A PDF Form Template. (Not for use with Word, Excel or PowerPoint templates.)
Parameter Description: Flatten Form fields on the output PDF. This parameter addresses a limitation in the iPhone/iPad PDF Reader which does not display values in PDF form fields. By flattening, the values of the fields are blended into the PDF background and are thus visible on iPads.
Because this parameter flattens field contents, it is not compatible with form fields that contain code such as javascript.
