Detailed Description

create a leader with optional label and arrows

vtkLeaderActor2D creates a leader with an optional label and arrows. (A leader is typically used to indicate distance between points.) vtkLeaderActor2D is a type of vtkActor2D; that is, it is drawn on the overlay plane and is not occluded by 3D geometry. To use this class, you typically specify two points defining the start and end points of the line (x-y definition using vtkCoordinate class), whether to place arrows on one or both end points, and whether to label the leader. Also, this class has a special feature that allows curved leaders to be created by specifying a radius.

Use the vtkLeaderActor2D uses its superclass vtkActor2D instance variables Position and Position2 vtkCoordinates to place an instance of vtkLeaderActor2D (i.e., these two data members represent the start and end points of the leader). Using these vtkCoordinates you can specify the position of the leader in a variety of coordinate systems.

To control the appearance of the actor, use the superclasses vtkActor2D::vtkProperty2D and the vtkTextProperty objects associated with this actor.

Return 1 if this class is the same type of (or a subclass of) the named class.

Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkActor2D.

◆ PrintSelf()

void vtkLeaderActor2D::PrintSelf ( ostream &  os,
vtkIndent  indent 
)
overridevirtual

Methods invoked by print to print information about the object including superclasses.

Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.

Reimplemented from vtkObject.

◆ New()

static vtkLeaderActor2D* vtkLeaderActor2D::New ( )
static

Instantiate object.

◆ SetRadius()

virtual void vtkLeaderActor2D::SetRadius ( double  )
virtual

Set/Get a radius which can be used to curve the leader.

If a radius is specified whose absolute value is greater than one half the distance between the two points defined by the superclasses' Position and Position2 ivars, then the leader will be curved. A positive radius will produce a curve such that the center is to the right of the line from Position and Position2; a negative radius will produce a curve in the opposite sense. By default, the radius is set to zero and thus there is no curvature. Note that the radius is expresses as a multiple of the distance between (Position,Position2); this avoids issues relative to coordinate system transformations.

◆ GetRadius()

virtual double vtkLeaderActor2D::GetRadius ( )

◆ SetLabel()

virtual void vtkLeaderActor2D::SetLabel ( const char *  )

◆ SetAutoLabel()

virtual void vtkLeaderActor2D::SetAutoLabel ( vtkTypeBool  )
virtual

Enable auto-labelling.

In this mode, the label is automatically updated based on distance (in world coordinates) between the two end points; or if a curved leader is being generated, the angle in degrees between the two points.

◆ GetAutoLabel()

◆ AutoLabelOn()

virtual void vtkLeaderActor2D::AutoLabelOn ( )
virtual

◆ AutoLabelOff()

virtual void vtkLeaderActor2D::AutoLabelOff ( )
virtual

◆ SetLabelFormat()

virtual void vtkLeaderActor2D::SetLabelFormat ( const char *  )
virtual

Specify the format to use for auto-labelling.

◆ GetLabelFormat()

virtual char* vtkLeaderActor2D::GetLabelFormat ( )
virtual

◆ GetLength()

virtual double vtkLeaderActor2D::GetLength ( )
virtual

Obtain the length of the leader if the leader is not curved, otherwise obtain the angle that the leader circumscribes.

◆ GetAngle()

virtual double vtkLeaderActor2D::GetAngle ( )
virtual

◆ RenderOverlay()

int vtkLeaderActor2D::RenderOverlay ( vtkViewport viewport)
overridevirtual

Methods required by vtkProp and vtkActor2D superclasses.

Reimplemented from vtkProp.

◆ RenderOpaqueGeometry()

int vtkLeaderActor2D::RenderOpaqueGeometry ( vtkViewport )
overridevirtual

WARNING: INTERNAL METHOD - NOT INTENDED FOR GENERAL USE DO NOT USE THESE METHODS OUTSIDE OF THE RENDERING PROCESS All concrete subclasses must be able to render themselves.

There are four key render methods in vtk and they correspond to four different points in the rendering cycle. Any given prop may implement one or more of these methods. The first method is intended for rendering all opaque geometry. The second method is intended for rendering all translucent polygonal geometry. The third one is intended for rendering all translucent volumetric geometry. Most of the volume rendering mappers draw their results during this third method. The last method is to render any 2D annotation or overlays. Each of these methods return an integer value indicating whether or not this render method was applied to this data.

Does this prop have some translucent polygonal geometry?

Reimplemented from vtkProp.

◆ ReleaseGraphicsResources()

WARNING: INTERNAL METHOD - NOT INTENDED FOR GENERAL USE Release any graphics resources that are being consumed by this actor.

The parameter window could be used to determine which graphic resources to release.
