WpfFreehandAnnotation Methods

Defines the parent-child relationship between two visuals.

This method is called by the WpfAnnotationCanvas to ask the annotation for Grip creation.

Called when the annotation grips need to be created.

Calculates the geometry of the annotation with the specified parameters.

Determines whether the calling thread has access to this DispatcherObject.

Clears the local value of a property. The property to be cleared is specified by a DependencyProperty identifier.

Clears the local value of a read-only property. The property to be cleared is specified by a DependencyPropertyKey.

Creates a copy of the anotation.

Derived classes must override this method and return a copy of itself.

Coerces the value of the specified dependency property. This is accomplished by invoking any CoerceValueCallback function specified in property metadata for the dependency property as it exists on the calling DependencyObject.

This method creates an AnnotationData copy of this annotation for serialization.

This method is used to serialize the annotation.

Ends the "create" mode for the annotation.

Determines whether a provided DependencyObject is equivalent to the current DependencyObject.

Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection.

Returns the common ancestor of two visual objects.

Gets a hash code for this DependencyObject.

Creates a specialized enumerator for determining which dependency properties have locally set values on this DependencyObject.

returns the Point objects as an array.

Gets the Type of the current instance.

Returns the current effective value of a dependency property on this instance of a DependencyObject.

Returns the specified Visual in the parent VisualCollection.

This method will determine whether the specified point is on the annotation.

Determines whether a point coordinate value is within the bounds of the visual object.

Determines whether a geometry value is within the bounds of the visual object.

Re-evaluates the effective value for the specified dependency property

Forces the annotation to redraw itself.

Determines whether the visual object is an ancestor of the descendant visual object.

Determines whether the visual object is a descendant of the ancestor visual object.

Creates a shallow copy of the current Object.

Mirrors the annotation in the specified direction.

This method will correct any negative points in the collection.

corrects any negitive points in the collection

Called when the FillProperty has changed.

Called after the annotation has been created.

Called when the FontProperty has changed.

Called when the OutlineProperty has changed.

Called when the Canvas property has changed.

Called when the GripMode property has been changed.

Called when a grip for the annotation has moved.

Called when a MouseDown event has been raised for the annotation.

Called when a MouseMove event has been raised for the annotation.

Called when a MouseUp event has been raised for the annotation.

Raises the PropertyChanged event.

Called when the document has been rotated.

Called when the Selected property has been changed.

Called when the VisualCollection of the visual object is modified.

Called when the parent of the visual object is changed.

Called when a request operation has been raised on the annotation.

Converts a Point in screen coordinates into a Point that represents the current coordinate system of the Visual.

Converts a Point that represents the current coordinate system of the Visual into a Point in screen coordinates.

This method is used to calculate the expected render bounds of an annotation if its rotation was changed.

This method is used to force an event in the annotation.

Returns the local value of a dependency property, if it exists.

This method will remove the annotation from its parent layer.

Removes the parent-child relationship between two visuals.

Call this method to replace the current annotation grips with new grips.

This method will reset the internal Matrix used for mirroring.

This method will update the Point values to fill the provided size.

This method will append a rotation to the annotation's current rotation.

Puts the array of points through a matrix rotation transform

Sets the value of a dependency property without changing its value source.

Call this method to add or update the grip positions.

This method will update the Location and Size properties based on the point values.

Sets the alpha values for the Fill and Outline of the annotation.

Derived class should call this method to indicate that their creation process has completed.

Sets the local value of a dependency property, specified by its dependency property identifier.

Sets the local value of a read-only dependency property, specified by the DependencyPropertyKey identifier of the dependency property.

Returns a value that indicates whether serialization processes should serialize the value for the provided dependency property.

Returns a string that represents the current object.

Returns a transform that can be used to transform coordinates from the Visual to the specified Visual ancestor of the visual object.

Returns a transform that can be used to transform coordinates from the Visual to the specified Visual3D ancestor of the visual object.

Returns a transform that can be used to transform coordinates from the Visual to the specified visual object descendant.

Returns a transform that can be used to transform coordinates from the Visual to the specified visual object.

Enforces that the calling thread has access to this DispatcherObject.
