of the rectangle bounding the circle, and (0,0) is the upper left-hand side of the rectangle
bounding the circle.
Here’s an example of the GradientOrigin being set to (0.2,0.2):
The SpreadMethod allows you to determine how the gradient repeats. It can be set
to one of three values: Pad is the default, and it means that the gradient fades evenly
between colors, and that the bounding rectangle is filled with the last color on the gradient;
Reflect means that once the gradient is filled, it is reversed to fill in the remainder;
and Repeat means that once the gradient is filled, it is repeated. These are particularly
useful when used in combination with the RadiusX and RadiusY properties.
Here’s an example of a RadialGradientBrush using the Reflect value in the
SpreadMethod:
RadiusX and RadiusY are used to set the desired radius of the gradient. The default
value of this is 0.5, so specifying a value less than this will mean that multiple gradients
will be used in the fill. This is probably best shown by example:
