Form support in Nutrient

Nutrient supports all form types listed in the PDF specification.

FormField represents a field without its own visual appearance. FormElement represents the visible annotation for one control within a field.

Disabling all form interactions

Call formEditingEnabled(false) to disable all form interactions and modifications:

val builder = PdfActivityConfiguration.Builder(context)
builder.formEditingEnabled(false)

Licensing

PDF Forms requires a separate license component. Without it, your app can’t view or interact with PDF forms. Contact Sales to add the component, or use a trial license to evaluate it.

Signature fields and elements require one of these license conditions:

  • Electronic Signatures or Digital Signatures is included.
  • The original license dates from April 2021 or earlier.

Otherwise, Nutrient hides signature elements but displays other form elements. For signature features, refer to the signatures guide.
