RadiusX Property (RectangleGeometry)
Gets or sets the x-radius of the ellipse used to round the corners of the rectangle geometry.
<object RadiusX="Double" .../>
value = object.RadiusX
object.RadiusX = value
The x-radius of the ellipse used to round the corners of the rectangle geometry.
This property is read/write. The default value is 0.
For the rectangle geometry to have rounded corners, both the RadiusX and RadiusY properties must be non-zero.
A value greater than or equal to zero and less than or equal to half the rectangle's width that describes the x-radius of the ellipse is used to round the corners of the rectangle. Values greater than half the rectangle's width are treated as though equal to half the rectangle's width. Negative values are treated as positive values.
The following illustration shows three rectangles with varying degress of rounded corners.
