Syntax


public sealed class LinearGradientBrush : GradientBrush

XAML Implicit Collection Usage


<LinearGradientBrush ...>
  oneOrMoreGradientStops
</LinearGradientBrush

XAML Values

oneOrMoreGradientStops: One or more GradientStop object elements. Object elements defined here become members of the collection when code accesses the GradientStops property at run time.

Members

The LinearGradientBrush class has these types of members:

Constructors
Methods
Properties

Constructors

The LinearGradientBrush class has these constructors.

Constructor	Description
LinearGradientBrush()	Initializes a new instance of the LinearGradientBrush class.
LinearGradientBrush(GradientStopCollection, Double)	Initializes a new instance of the LinearGradientBrush class that has the specified GradientStopCollection and angle.

Methods

The LinearGradientBrush class has these methods. It also inherits methods from the Object class.

Method	Description
ClearValue	Clears the local value of a dependency property. (Inherited from DependencyObject)
GetAnimationBaseValue	Returns any base value established for a dependency property, which would apply in cases where an animation is not active. (Inherited from DependencyObject)
GetValue	Returns the current effective value of a dependency property from a DependencyObject. (Inherited from DependencyObject)
ReadLocalValue	Returns the local value of a dependency property, if a local value is set. (Inherited from DependencyObject)
SetValue	Sets the local value of a dependency property on a DependencyObject. (Inherited from DependencyObject)

Properties

The LinearGradientBrush class has these properties.

Property	Access type	Description
ColorInterpolationMode	Read/write	Gets or sets a ColorInterpolationMode enumeration value that specifies how the gradient's colors are interpolated. (Inherited from GradientBrush)
Dispatcher	Read-only	Gets the CoreDispatcher that this object is associated with. (Inherited from DependencyObject)
EndPoint	Read/write	Gets or sets the ending two-dimensional coordinates of the linear gradient.
EndPointProperty	Read-only	Identifies the EndPoint dependency property.
GradientStops	Read/write	Gets or sets the brush's gradient stops. (Inherited from GradientBrush)
MappingMode	Read/write	Gets or sets a BrushMappingMode enumeration value that specifies whether the positioning coordinates of the gradient brush are absolute or relative to the output area. (Inherited from GradientBrush)
Opacity	Read/write	Gets or sets the degree of opacity of a Brush. (Inherited from Brush)
RelativeTransform	Read/write	Gets or sets the transformation that is applied to the brush using relative coordinates. (Inherited from Brush)
SpreadMethod	Read/write	Gets or sets the type of spread method that specifies how to draw a gradient that starts or ends inside the bounds of the object to be painted. (Inherited from GradientBrush)
StartPoint	Read/write	Gets or sets the starting two-dimensional coordinates of the linear gradient.
StartPointProperty	Read-only	Identifies the StartPoint dependency property.
Transform	Read/write	Gets or sets the transformation that is applied to the brush. (Inherited from Brush)

Examples

This example creates a linear gradient with four colors and uses it to paint a Rectangle.

XAML


<StackPanel>
  <!-- This rectangle is painted with a vertical linear gradient. -->
  <Rectangle Width="200" Height="100">
    <Rectangle.Fill>
      <LinearGradientBrush StartPoint="0.5,0" EndPoint="0.5,1">
        <GradientStop Color="Yellow" Offset="0.0" />
        <GradientStop Color="Red" Offset="0.25" />
        <GradientStop Color="Blue" Offset="0.75" />
        <GradientStop Color="LimeGreen" Offset="1.0" />
      </LinearGradientBrush>
    </Rectangle.Fill>
  </Rectangle>
</StackPanel>

This illustration shows the resulting gradient. The gradient axis is marked with a dashed line and the gradient stops are marked with circles.
