Thank you for contacting support.

Aspose.PDF for .NET API supports setting axial shading with GradientAxialShading class but currently an exception is being thrown while setting it. Therefore, we have logged a ticket with ID PDFNET-46699 in our issue management system for further investigations and resolution. We will let you know as soon as some update will be available in this regard.

Thank you for your quick response!
