Assembly:  System.Windows (in System.Windows.dll)


Public Property RadiusX As Double
public double RadiusX { get; set; }
<RadialGradientBrush RadiusX="double"/>

Property Value

Type: System.Double
The horizontal radius of the outermost circle of the radial gradient. The default value is 0.5.


Dependency property identifier field: RadiusXProperty

When the mapping mode is RelativeToBoundingBox (the default), RadiusX and RadiusY are "logical vectors", where values between 0 and 1 are mapped against the total size of the eventual bounding box where the brush is applied. The 0.5 default values for RadiusX and RadiusY create a circle that reaches the edge of the bounding box under this mapping mode. If the mapping mode is Absolute, then RadiusX and RadiusY should be given as a double value in the coordinate system.
