Gets or sets the horizontal radius of the outer circle of the radial gradient.
Assembly: System.Windows (in System.Windows.dll)
Dependency property identifier field: RadiusXProperty
When the mapping mode is RelativeToBoundingBox (the default), 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 and RadiusY create a circle that reaches the edge of the bounding box under this mapping mode. If the mapping mode is Absolute, then and RadiusY should be given as a double value in the coordinate system.
