Composing signature with solid brush background

GroupDocs.Signature provides SolidBrush class to specify solid filling signature background for Text and Stamp signature types

Here are the steps to add Text signature into document with GroupDocs.Signature:

  • Create new instance of Signature class and pass source document path or stream as a constructor parameter.

  • Instantiate the SignOptions object with all required additional options and setup Background.Brush property with instance of SolidBrush

  • Call Sign method of Signature class instance and pass SignOptions to it. 

  • Analyze SignResult result to check newly created signatures if needed. 

This example shows how to add Text signature with solid brush background. See SignResult

using (Signature signature = new Signature("sample.pdf"))
    TextSignOptions options = new TextSignOptions("John Smith")
        // adjust signature appearance brush
        // setup background
        Background = new Background()
            Color = Color.LimeGreen,
            Transparency = 0.5,
            Brush = new SolidBrush(Color.LimeGreen)
        // locate signature
        Width = 100,
        Height = 80,
        VerticalAlignment = Domain.VerticalAlignment.Center,
        HorizontalAlignment = Domain.HorizontalAlignment.Center,
        Margin = new Padding() { Top = 20, Right = 20 },
        // set alternative signature implementation on document page
        SignatureImplementation = TextSignatureImplementation.Image
    // sign document to file
    signature.Sign("signed.pdf", options);
