sealed class

This class defines a gradient brush that shades from one color at the center of a GraphicsPath to another at each edge of the path . The CenterPoint can be set arbitrarily.

You can define a basic fade by setting the CenterColor , populating the SurroundColors array with one Color value for each of the points defining the path, and setting the Blend object.

Alternatively, you can go for a more complex fade, by setting a ColorBlend object into the InterpolationColors property.

You can also set the bounding Rectangle for the path, and the WrapMode defining how points outside that rectangle should be filled.

The path itself is set in the constructor of the object and cannot be modified subsequently, but you can apply a Transform with the usual array of helper methods , such as RotateTransform() and MultiplyTransform() .
