I've created https://issues.apache.org/jira/browse/PDFBOX-2841 =
<https://issues.apache.org/jira/browse/PDFBOX-2841> to handle that.

- getOptions() returns the export values of the radio button group so =
that's not what you are looking for (and we might rename that method to =
better reflect it's intention)
- you could use getWidgets() to get the individual radio buttons and =
from there for each individual widget =
widget.getAppearance().getNormalAppearance() gives you the dictionary to =
get the values from.
