public class PdfRadialShading extends AbstractPdfShadingBlend
AbstractPdfShading and AbstractPdfShadingBlend classes
and is in charge of Shading Dictionary with radial type, that defines a colour blend that varies between two circles.
This type of shading shall not be used with an Indexed colour space
