The PdfDigitalSignatureElement type exposes the following members.
| Name | Description | |
|---|---|---|
| ActualText |
Gets or sets the exact text represented by this element (the structure element's
/ActualText entry), used when the drawn glyphs do not map to readable text.
(Inherited from PdfPageElement) | |
| AlternateText |
Gets or sets the alternate text describing this element for assistive technology (the
structure element's /Alt entry). Required on figures for PDF/UA conformance.
(Inherited from PdfPageElement) | |
| Artifact |
Gets or sets a value indicating whether this element is an artifact — decorative or layout
content that carries no meaning and is excluded from the logical structure (backgrounds,
rules, running headers). Takes precedence over TagType.
(Inherited from PdfPageElement) | |
| Certificate | Gets the certificate used to create the signature, or null when the element was created with an external signer. | |
| ContactInfo | Gets or sets the contact information. | |
| DigestAlgorithm | Gets or sets the hash algorithm the signature is computed with. | |
| EnableLtv | Gets or sets a value indicating whether the signature is made LTV-enabled (long-term validation). | |
| Location | Gets or sets the location of the signing. | |
| Reason | Gets or sets the reason for the signing. | |
| SignatureBackgroundImage | Gets or sets an image drawn behind the text of the visible signature - a company logo, a seal, a scanned handwritten signature - in place of the default mark. | |
| SignatureBackgroundOpacity | Gets or sets how strongly the background of the visible signature is drawn, from 0 (no background) to 1 (the image's own colours). | |
| TagType |
Gets or sets the structure type used to tag this element in a tagged (accessible) document.
Ignored unless the document's tagged mode (PdfDocument.Tagged) is enabled. Null
(default) leaves the element untagged unless Artifact is set.
