Stroke Class
Represents a collection of points that correspond to a stylus-down, move, and stylus-up sequence.
Namespace: System.Windows.Ink
Assembly: System.Windows (in System.Windows.dll)
The Stroke type exposes the following members.
| Name | Description | |
|---|---|---|
![]() ![]() | Stroke() | Initializes a new instance of the Stroke class. |
![]() ![]() | Stroke(StylusPointCollection) | Initializes a new instance of the Stroke class with the specified StylusPointCollection. |
| Name | Description | |
|---|---|---|
![]() ![]() | Dispatcher | Gets the Dispatcher this object is associated with. (Inherited from DependencyObject.) |
![]() ![]() | DrawingAttributes | Gets or sets the properties of the stroke, such as Height, Width, Color, or OutlineColor. |
![]() ![]() | StylusPoints | Gets or sets the stylus points of the Stroke. |
| Name | Description | |
|---|---|---|
![]() ![]() | CheckAccess | Determines whether the calling thread has access to this object. (Inherited from DependencyObject.) |
![]() ![]() | ClearValue | Clears the local value of a dependency property. (Inherited from DependencyObject.) |
![]() ![]() | Equals(Object) | Determines whether the specified Object is equal to the current Object. (Inherited from Object.) |
![]() ![]() | Finalize | Allows an object to try to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection. (Inherited from Object.) |
![]() ![]() | GetAnimationBaseValue | Returns any base value established for a Silverlight dependency property, which would apply in cases where an animation is not active. (Inherited from DependencyObject.) |
![]() ![]() | GetBounds | Retrieves the bounding box for the Stroke object. |
![]() ![]() | GetHashCode | Serves as a hash function for a particular type. (Inherited from Object.) |
![]() ![]() | GetType | Gets the Type of the current instance. (Inherited from Object.) |
![]() ![]() | GetValue | Returns the current effective value of a dependency property from a DependencyObject. (Inherited from DependencyObject.) |
![]() ![]() | HitTest | Indicates whether a specified StylusPointCollection intersects with a Stroke object. |
![]() ![]() | MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
![]() ![]() | 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.) |
![]() ![]() | ToString | Returns a string that represents the current object. (Inherited from Object.) |
A Stroke is the data object that is collected from a pointing device, such as a tablet pen or a mouse. The Stroke can be created and manipulated programmatically, and can be represented visually on an ink-enabled element, such as the InkPresenter. A Stroke contains information about both its position and appearance. The StylusPoints property is a collection of StylusPoint objects that specifies the geometry of the Stroke. The DrawingAttributes property specifies a stroke's appearance.
The following code example shows how can create a static stroke using XAML.
<Canvas> <InkPresenter x:Name="MyIP" Height="100" Width="200" Background="Transparent"> <InkPresenter.Strokes> <StrokeCollection> <Stroke> <Stroke.DrawingAttributes> <DrawingAttributes Color="Red" OutlineColor="Black" Width="5" Height="5"/> </Stroke.DrawingAttributes> <Stroke.StylusPoints> <StylusPoint X="50" Y="50"/> <StylusPoint X="55" Y="55"/> <StylusPoint X="60" Y="60"/> <StylusPoint X="65" Y="65"/> <StylusPoint X="70" Y="70"/> <StylusPoint X="75" Y="75"/> </Stroke.StylusPoints> </Stroke> </StrokeCollection> </InkPresenter.Strokes> </InkPresenter> </Canvas>
