Composing signature with radial gradient brush background Leave feedback
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.setBrush 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
Signature signature = new Signature("sample.pdf");
TextSignOptions options = new TextSignOptions("John Smith")
// adjust signature appearance brush
// setup background
Background background = new Background();
background.setColor(Color.GREEN);
background.setTransparency(0.5);
background.setBrush(new RadialGradientBrush(Color.GREEN, Color.WHITE));
options.setBackground(background);
// locate signature
options.setWidth(100);
options.setHeight(80);
options.setVerticalAlignment(VerticalAlignment.Center);
options.setHorizontalAlignment(HorizontalAlignment.Center);
Padding padding = new Padding();
padding.setTop(20);
padding.setRight(20);
options.setMargin(padding);
// set alternative signature implementation on document page
options.setSignatureImplementation(TextSignatureImplementation.Image);
// sign document to file
SignResult signResult = signature.sign("signed.pdf", options);
// analyzing result
System.out.print("List of newly created signatures:");
int number = 1;
for(BaseSignature temp : signResult.getSucceeded())
{
System.out.print("Signature #"+ number++ +": Type: "+temp.getSignatureType()+" Id:"+temp.getSignatureId()+
",Location: "+temp.getLeft()+"x"+temp.getTop()+". Size: "+temp.getWidth()+"x"+temp.getHeight());
}
