IXRRadialGradientBrush (Windows Embedded CE 6.0)

1/6/2010

This class represents a brush that paints an area with a radial gradient. A focal point defines the beginning of the gradient, and an ellipse defines the endpoints of the gradient.

Syntax

class IXRRadialGradientBrush : public IXRGradientBrush

Methods

Method	Description
IXRRadialGradientBrush::GetCenter	Retrieves the center of the outer ellipse of this radial gradient.
IXRRadialGradientBrush::GetGradientOrigin	Retrieves the location of the focal point where the radial gradient begins.
IXRRadialGradientBrush::GetRadiusX	Retrieves the horizontal radius of the outer ellipse of this radial gradient.
IXRRadialGradientBrush::GetRadiusY	Retrieves the vertical radius of the outer ellipse of this radial gradient.
IXRRadialGradientBrush::SetCenter	Sets the center of the outer ellipse of this radial gradient.
IXRRadialGradientBrush::SetGradientOrigin	Sets the location of the focal point where the radial gradient begins.
IXRRadialGradientBrush::SetRadiusX	Sets the horizontal radius of the outer ellipse of this radial gradient.
IXRRadialGradientBrush::SetRadiusY	Sets the vertical radius of the outer ellipse of this radial gradient.

Remarks

The IXRRadialGradientBrush object resembles the IXRLinearGradientBrush object. However, the linear gradient has a starting point and an endpoint that define the gradient vector, whereas the radial gradient has a focal point that defines the starting point and an ellipse that defines the endpoints. In other words, a gradient stop at 1 defines the color at the ellipse circumference. A gradient stop at 0 defines the color at the focal point.

When you set identical RadiusX and RadiusY values, the shape of the outer ellipse of this radial gradient is a circle.

You can also define a radial gradient brush in Microsoft Silverlight 2 XAML. For information about the differences between XAML in Silverlight for Windows Embedded and Silverlight 2, see Differences Between Silverlight for the Web and Silverlight for Windows Embedded. For more information about how to define this element in the source XAML for your application, see this Microsoft Web site.
