```csharp
SignatureImage signatureImage = new(@"Images\alex-smith-signature.svg", 0);
SignatureField approval = new(new System.Drawing.Size(3000, 1000), "ApproverSignature", 10) { Image = signatureImage };
textControl.SignatureFields.Add(approval, FrameInsertionMode.AsCharacter);

signatureImage.ExportFileName = @"Exports\alex-smith-signature.svg";
if (!string.IsNullOrWhiteSpace(signatureImage.ExportFileName))
{
    Console.WriteLine($"Export File Name: {signatureImage.ExportFileName}");
}
```

```vbnet
Dim signatureImage As New SignatureImage("Images\alex-smith-signature.svg", 0)
Dim approval As New SignatureField(New System.Drawing.Size(3000, 1000), "ApproverSignature", 10) With { .Image = signatureImage }
textControl.SignatureFields.Add(approval, FrameInsertionMode.AsCharacter)

signatureImage.ExportFileName = "Exports\alex-smith-signature.svg"
If Not String.IsNullOrWhiteSpace(signatureImage.ExportFileName) Then
