import groupdocs.signature.domain as gsd

 # Open the document
with gs.Signature(sample_pdf) as signature:
    # Set up text signature options
    options = gso.QrCodeSignOptions("John Smith")
    options.encode_type = gsd.QrCodeTypes.QR
    options.left = 50
    options.top = 200
    options.width = 100
    options.height = 30

    # Sign document and save
    result = signature.sign(output_file_path, options)
```

## Sign with digital signature the PNG file

```py
import groupdocs.signature as gv
