Stroke Class

Represents a single ink stroke.

A stroke is a set of properties and point data that the digitizer captures that represent the coordinates and properties of a known ink mark. It is the set of data that is captured in a single pen down, up, or move sequence.

Methods

Method	Description
Clip	Removes the portions of the Stroke object that are outside a given rectangle.
Equals	Determines whether two Object instances are equal. Inherited from Object .
Finalize	Allows an Object to attempt to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection. Inherited from Object .
FindIntersections	Finds the points where this Stroke object intersects other Stroke objects within a given Strokes collection.
GetBoundingBox	Returns the bounding Rectangle that contains the Stroke object.
GetFlattenedBezierPoints	Returns the array of actual points that are used to approximate the Bezier representation of a Stroke object.
GetHashCode	Serves as a hash function for a particular type, suitable for use in hashing algorithms and data structures like a hash table. Inherited from Object .
GetPacketData	Returns the packet data associated with one or more points in a Stroke object.
GetPacketDescriptionPropertyMetrics	Returns the metrics for a given packet description type.
GetPacketValuesByProperty	Returns the data for a known packet property from one or more packets in the Stroke object.
GetPoint	Returns the Point structure at the specified index in a Stroke object.
GetPoints	Returns an array of Point structures that make up the Stroke object.
GetRectangleIntersections	Returns an array of Point structures that indicate where a Stroke object intersects a given Rectangle .
GetType	Gets the Type of the current instance. Inherited from Object .
HitTest	Returns a value that indicates whether a Stroke object is either completely inside or intersected by a given circle.
MemberwiseClone	Creates a shallow copy of the current Object . Inherited from Object .
Move	Applies a translation to the ink of the Stroke object.
NearestPoint	Returns the location on the Stroke object nearest to a specified Point .
ReferenceEquals	Determines whether the specified Object instances are the same instance. Inherited from Object .
Rotate	Rotates the Stroke object around a center point.
Scale	Scales the Stroke object in the X and Y dimensions.
ScaleToRectangle	Scales the Stroke object to fit in the specified Rectangle structure.
SetPacketValuesByProperty	Sets the packet values for a particular PacketProperty object within this Stroke object.
SetPoint	Sets the Point structure at the specified index in a Stroke object.
SetPoints	Sets an array of Point structures at the specified indices in a Stroke object.
Shear	Shears the Stroke object by the specified horizontal and vertical factors.
Split	Splits the Stroke object at the specified location on the Stroke object and returns the new Stroke object.
ToString	Returns a String that represents the current Object . Inherited from Object .
Transform	Applies a linear transformation to a Stroke object.

Properties

Property	Description
BezierCusps	Gets an array that contains the indices of the cusps of the Bezier approximation of the Stroke object.
BezierPoints	Gets the array of control points that represent the Bezier approximation of the stroke.
Deleted	Gets a value that indicates whether the Stroke object has been deleted from its parent Ink object.
DrawingAttributes	Gets or sets the drawing attributes to apply to ink as it is drawn.
ExtendedProperties	Gets the collection of application-defined data.
Id	Gets the identifier of the Stroke object.
Ink	Gets the parent Ink object of the Stroke object.
PacketCount	Gets the number of packets received for a Stroke object.
PacketDescription	Gets an array of type Guid that describes the types of packet data stored in the Stroke object.
PacketSize	Gets the size, in bytes, of a packet.
PolylineCusps	Gets an array that contains the indices of the cusps of the Stroke object.
