Visual Basic (Declaration)
Public Property Center As Point
Dim instance As RadialGradientBrush
Dim value As Point
value = instance.Center
instance.Center = value
public Point Center { get; set; }
public:
property Point Center {
Point get ();
void set (Point value);

XAML Property Element Usage
<object>
<object.Center>
<Point .../>
</object.Center>

<object Center="Point" .../>
The default central point location of the gradient circle is (0.5, 0.5).
This example shows how to use the RadialGradientBrush class to paint an area with a radial gradient.
The following example uses a RadialGradientBrush to paint a rectangle with a radial gradient that transitions from yellow to red to blue to lime green.

The examples in this topic
use
the default coordinate system for setting
control points
. The default coordinate system is relative to a bounding box: 0 indicates 0 percent of the bounding box
,
and 1 indicates 100 percent of the bounding box. You can change this coordinate system by setting the
MappingMode property to the value Absolute. An absolute coordinate system is not relative to a bounding box. Values are interpreted directly in local space.
