Signature Fields

TX Text Control supports signature fields which can be associated with a digital certificate. A signature field can be positioned such as an image or textframe, either geometrically or as a single character. Geometrically, its position can either be relative to a paragraph to which it is anchored or relative to the complete document. The SignatureField class handles the positioning of the signature field in the document. A signature field acts as a site for a signature image. Such an image can be added, when the document is designed or later when it is digitally signed, using the signature field's Image property. When the document is saved as a .pdf document, each signature field can be associated with a digital certificate using the SaveSettings.SignatureFields property. To associate the certificate a signature field must have a name. It can be specified through the field's constructor or its Name property. Additionally, a signature field can store data of an suggested signer which can be set with the SignatureField.SignerData property. All signature fields in a document are contained in a SignatureFieldCollection. The collection can also be used to add or remove signature fields. It can be obtained through the TextControl.SignatureFields, WPF.TextControl.SignatureFields or ServerTextControl.SignatureFields property. The TextControl.SignatureFieldLayoutDialog and WPF.TextControl.SignatureFieldLayoutDialog methods opens a dialog box, which offers layout settings such as positioning, size and text distances and image saving options, when a signature image exists. A signature field can be saved with the TX Text Control format and the .PDF, .DOCX und .RTF formats. With all other formats the signature image is saved. Events occur, when a signature field is created (SignatureFieldCreated), deleted (SignatureFieldDeleted), selected (SignatureFieldSelected) or deselected (SignatureFieldDeselected).
