GradientBrush Class

Microsoft Silverlight will reach end of support after October 2021. Learn more.

An abstract class that describes a gradient, composed of gradient stops. Classes that derive from GradientBrush describe different ways of interpreting gradient stops.

Properties

	Name	Description
	ColorInterpolationMode	Gets or sets a ColorInterpolationMode enumeration value that specifies how the gradient's colors are interpolated.
	Dispatcher	Gets the Dispatcher this object is associated with. (Inherited from DependencyObject.)
	GradientStops	Gets or sets the brush's gradient stops.
	MappingMode	Gets or sets a BrushMappingMode enumeration value that specifies whether the positioning coordinates of the gradient brush are absolute or relative to the output area.
	Opacity	Gets or sets the degree of opacity of a Brush. (Inherited from Brush.)
	RelativeTransform	Gets or sets the transformation that is applied to the brush using relative coordinates. (Inherited from Brush.)
	SpreadMethod	Gets or sets the type of spread method that specifies how to draw a gradient that starts or ends inside the bounds of the object to be painted.
	Transform	Gets or sets the transformation that is applied to the brush. (Inherited from Brush.)

Methods

	Name	Description
	CheckAccess	Determines whether the calling thread has access to this object. (Inherited from DependencyObject.)
	ClearValue	Clears the local value of a dependency property. (Inherited from DependencyObject.)
	Equals(Object)	Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
	Finalize	Allows an object to try to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection. (Inherited from Object.)
	GetAnimationBaseValue	Returns any base value established for a Silverlight dependency property, which would apply in cases where an animation is not active. (Inherited from DependencyObject.)
	GetHashCode	Serves as a hash function for a particular type. (Inherited from Object.)
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	GetValue	Returns the current effective value of a dependency property from a DependencyObject. (Inherited from DependencyObject.)
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	ReadLocalValue	Returns the local value of a dependency property, if a local value is set. (Inherited from DependencyObject.)
	SetValue	Sets the local value of a dependency property on a DependencyObject. (Inherited from DependencyObject.)
	ToString	Returns a string that represents the current object. (Inherited from Object.)
