Planned support for radio buttons

[scottstarsman]

Is there a plan to support radio buttons in the near future? Thanks

It is not on my list currently, I'm afraid.
It would be another feature, which I need to create myself, because MuPDF has no support for it yet (last time I looked).
There are already quite a few things in this area which I added on top - and, regularly after each new MuPDF version, they cause significant effort to get them going again.

Thanks for your fast reply. Is there some raw data available from the parsed document that I could use to extract this info?

Other than that, this has proven to be the best PDF tools I've used. Thanks for your work!

Thank you!

raw data available from the parsed document

You can walk through a page's annots, fields, links and then inspect their respective object definition, i.e. its xref "source". There always will exist things like annot.xref, field.xref etc. E.g.

>>> for field in page.widgets():
	if field.field_type_string == "RadioButton":
		print(doc.xref_object(field.xref))

Excellent! I'll give that a try and see if I can get those fields. Thanks again for your help.
