Struct pdfium_render::form_field_text::PdfFormTextField

pub struct PdfFormTextField<'a> { /* private fields */ }

Expand description

A single PdfFormField of type PdfFormFieldType::Text. The form field object defines an interactive data entry widget that allows the user to enter data by typing.

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.
