GradientBrush.SpreadMethod Property

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.

public GradientSpreadMethod SpreadMethod { get; set; }
/** @property */
public GradientSpreadMethod get_SpreadMethod ()

/** @property */
public void set_SpreadMethod (GradientSpreadMethod value)

public function get SpreadMethod () : GradientSpreadMethod

public function set SpreadMethod (value : GradientSpreadMethod)

<object SpreadMethod="GradientSpreadMethod" .../>

Property Value

The type of spread method used to paint the gradient. The default value is Pad.

The following illustration shows the available spread methods and their effect on LinearGradientBrush and RadialGradientBrush. The red line indicates the gradient space. A LinearGradientBrush defines its gradient space with its StartPoint and EndPoint properties. A RadialGradientBrush defines its gradient space with its Center, RadiusX, and RadiusY properties.

Gradient spread methods


Different GradientSpread settings

The following example applies different SpreadMethod settings to several LinearGradientBrush and RadialGradientBrush objects.
