PdfFormSignatureField

Struct PdfFormSignatureField 

Source
pub struct PdfFormSignatureField<'a> { /* private fields */ }
Expand description

A single PdfFormField of type PdfFormFieldType::Signature. The form field object defines an interactive data entry widget that allows the user to draw a signature.

Form fields in Pdfium are wrapped inside page annotations of type PdfPageAnnotationType::Widget or PdfPageAnnotationType::XfaWidget. User-specified values can be retrieved directly from each form field object by unwrapping the form field from the annotation, or in bulk from the PdfForm::field_values() function.
