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:

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 SolidBrush(Color.LIGHT_GRAY));
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());
}
