Supported PDF form fields on Android
Nutrient supports all form types specified by the PDF specification.
| Type | Field object | Annotation object |
|---|---|---|
| Check, radio, and push buttons | ButtonFormField | ButtonFormElement |
| List and combo boxes | ChoiceFormField | ChoiceFormElement |
| Text | TextFormField | TextFormElement |
| Signatures | SignatureFormField | SignatureFormElement |
We differentiate between field objects and annotation objects; field objects have no visual representation of their own and are represented by FormField, while annotation objects are visual representations of a single control inside a form field and are represented by FormElement.
