The desired layout information may be stored in the TP entry of the appearance characteristics dictionary:
| Key | Type | Value |
|---|---|---|
| TP | integer | (Optional; pushbutton fields only) A code indicating where to position the text of the widget annotation’s caption relative to its icon: 0 No icon; caption only 1 No caption; icon only 2 Caption below the icon 3 Caption above the icon 4 Caption to the right of the icon 5 Caption to the left of the icon 6 Caption overlaid directly on the icon Default value: 0. |
(ISO 32000-1, Table 189 – Entries in an appearance characteristics dictionary)
Thus, you may want to try setting the TP entry of the PDAppearanceCharacteristicsDictionary fieldAppearance in the referenced code to 1.
