## SignatureLineOptions class


Allows to specify options for signature line being inserted. Used in [DocumentBuilder](../documentbuilder/). To learn more, visit the [Work with Digital Signatures](https://docs.aspose.com/words/cpp/working-with-digital-signatures/) documentation article.

```cpp
class SignatureLineOptions : public System::Object
```

## Methods

| [set_ShowDate](./set_showdate/)(bool) | Setter for [Aspose::Words::SignatureLineOptions::get_ShowDate](./get_showdate/). |
| [set_Signer](./set_signer/)(const System::String\&) | Sets suggested signer of the signature line. Default value for this property is **empty string**. |
| [set_SignerTitle](./set_signertitle/)(const System::String\&) | Sets suggested signer's title. Default value for this property is **empty string**. |
| [SignatureLineOptions](./signaturelineoptions/)() |  |
| static [Type](./type/)() |  |

## Examples



Shows how to sign a document with a personal certificate and a signature line. 
```cpp
auto doc = System::MakeObject<Aspose::Words::Document>();
auto builder = System::MakeObject<Aspose::Words::DocumentBuilder>(doc);

auto signatureLineOptions = System::MakeObject<Aspose::Words::SignatureLineOptions>();
signatureLineOptions->set_Signer(u"vderyushev");
signatureLineOptions->set_SignerTitle(u"QA");
signatureLineOptions->set_Email(u"vderyushev@aspose.com");
signatureLineOptions->set_ShowDate(true);
signatureLineOptions->set_DefaultInstructions(false);
signatureLineOptions->set_Instructions(u"Please sign here.");
signatureLineOptions->set_AllowComments(true);

System::SharedPtr<Aspose::Words::Drawing::SignatureLine> signatureLine = builder->InsertSignatureLine(signatureLineOptions)->get_SignatureLine();
signatureLine->set_ProviderId(System::Guid::Parse(u"CF5A7BB4-8F3C-4756-9DF6-BEF7F13259A2"));

ASSERT_FALSE(signatureLine->get_IsSigned());
ASSERT_FALSE(signatureLine->get_IsValid());

doc->Save(get_ArtifactsDir() + u"DocumentBuilder.SignatureLineProviderId.docx");

auto signOptions = System::MakeObject<Aspose::Words::DigitalSignatures::SignOptions>();
signOptions->set_SignatureLineId(signatureLine->get_Id());
signOptions->set_ProviderId(signatureLine->get_ProviderId());
signOptions->set_Comments(u"Document was signed by vderyushev");
signOptions->set_SignTime(System::DateTime::get_Now());

System::SharedPtr<Aspose::Words::DigitalSignatures::CertificateHolder> certHolder = CertificateHolder::Create(get_MyDir() + u"morzal.pfx", u"aw");

DigitalSignatureUtil::Sign(get_ArtifactsDir() + u"DocumentBuilder.SignatureLineProviderId.docx", get_ArtifactsDir() + u"DocumentBuilder.SignatureLineProviderId.Signed.docx", certHolder, signOptions);

// Re-open our saved document, and verify that the "IsSigned" and "IsValid" properties both equal "true",
// indicating that the signature line contains a signature.
doc = System::MakeObject<Aspose::Words::Document>(System::String(get_ArtifactsDir() + u"DocumentBuilder.SignatureLineProviderId.Signed.docx"));
auto shape = System::ExplicitCast<Aspose::Words::Drawing::Shape>(doc->GetChild(NodeType::Shape, 0, true));
signatureLine = shape->get_SignatureLine();

ASSERT_TRUE(signatureLine->get_IsSigned());
ASSERT_TRUE(signatureLine->get_IsValid());
```
