Composing signature with radial gradient brush background
GroupDocs.Signature provides RadialGradientBrush class to specify filling signature background with radial gradients
Here are the steps to use Radial gradient brush 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 RadialGradientBrush
- 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 use Radial gradient brush for signature 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 RadialGradientBrush(Color.LimeGreen, Color.DarkGreen)
},
// 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);
}
