Remarks

Use this class to describe the colors in a LinearGradientBrush or RadialGradientBrush.

Note that this class does not provide an opacity property; to make a GradientStop semi-transparent, set its GradientStop.Color property with a transparent Color.

Freezable Features

A GradientStop is a type of Freezable object and therefore can be frozen to improve performance. For information about Freezable features, such as freezing and cloning, see the Freezable Objects Overview.
