RadiusY (RadialGradientBrush)
Microsoft Silverlight will reach end of support after October 2021. Learn more.
Gets or sets the vertical radius of the outermost circle of a radial gradient.

Property Value
Type: Double
The vertical radius of the outermost circle of a radial gradient.
This property is read/write. The default value is 0.5.
Remarks
The MappingMode property of a RadialGradientBrush determines whether the properties of the brush are interpreted as relative or absolute values. By default, RadiusY is treated as relative, which corresponds to a MappingMode of RelativeToBoundingBox. In this case, the default RadiusY value of 0.5 combined with the default Center value of 0.5,0.5 results in a circle as high as the area where the brush is applied, centered exactly on the middle of that area. A MappingMode of Absolute specifies that the RadiusY value is expressed in device-independent pixels, instead of being relative to the bounding box of the area where the brush is applied.
