## Examples


```cpp
Aspose::Cells::Startup();
//Instantiating a Workbook object
Workbook workbook;
Worksheet worksheet = workbook.GetWorksheets().Get(0);

// Create signature line object
SignatureLine s;
s.SetSigner("Simon Zhao");
s.SetTitle("Development Lead");
s.SetEmail("Simon.Zhao@aspose.com");
s.SetInstructions("Sign to confirm the excel content.");

// Adds a Signature Line to the worksheet.
Picture signatureLine = worksheet.GetShapes().AddSignatureLine(0, 0, s);


//Save the excel file.
workbook.Save("result.xlsx");
Aspose::Cells::Cleanup();
```
