PeachPDF
PeachPDF.PdfGenerateConfig
PdfGenerateConfig.EnableInteractivePdfForms Property
When set to true, PeachPDF emits real, fillable AcroForm fields (text, checkbox,
radio, select) for form elements whose resolved -peachpdf-pdf-form-field value
requests one, instead of the default static box rendering. Defaults to false - an
explicit, informed opt-in, exactly like EnableTaggedPdf.
