AcroForm RTF formatting support
Hi. How should I set value to AcroForm field with RTF formatting enabled? As I understand from the source code - this is not supported yet?
No, RTF formatting is not supported yet as this will need an HTML parser, among other things.
How could RTF formatting work, in theory? One must provide an HTML value (so it's not actually RTF markup, but HTML markup?) to field_value= and HexaPDF must parse it and draw an appropriate appearance with PDF objects? So it is some kind of a limited converter of HTML to PDF?
Yes, kinda like that. But the specification of the value is part of Adobe's XFA specification.
