Detailed Description

a actor that draws 2D data.

Date:

2001/10/11 13:35:59

Revision:

1.33

Thanks:

Thanks to Matt Turek who developed this class.

vtkActor2D is similar to vtkActor, but it is made to be used with two dimensional images and annotation. vtkActor2D has a position but does not use a transformation matrix like vtkActor (see the superclass vtkProp for information on positioning vtkActor2D). vtkActor2D has a reference to a vtkMapper2D object which does the rendering.

Member Function Documentation

void vtkActor2D::PrintSelf (  ostream &    os, vtkIndent    indent )  [virtual]

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 vtkProp. Reimplemented in vtkCaptionActor2D, vtkCubeAxesActor2D, vtkLegendBoxActor, vtkXYPlotActor, vtkAxisActor2D, vtkParallelCoordinatesActor, vtkScalarBarActor, and vtkScaledTextActor.

virtual const char* vtkActor2D::GetClassName (    )  [virtual]

Return the class name as a string. This method is defined in all subclasses of vtkObject with the vtkTypeMacro found in vtkSetGet.h. Reimplemented from vtkProp. Reimplemented in vtkCaptionActor2D, vtkCubeAxesActor2D, vtkLegendBoxActor, vtkXYPlotActor, vtkAxisActor2D, vtkParallelCoordinatesActor, vtkScalarBarActor, and vtkScaledTextActor.

int vtkActor2D::IsTypeOf (  const char *    type )  [static]

Return 1 if this class type 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 vtkProp. Reimplemented in vtkCaptionActor2D, vtkCubeAxesActor2D, vtkLegendBoxActor, vtkXYPlotActor, vtkAxisActor2D, vtkParallelCoordinatesActor, vtkScalarBarActor, and vtkScaledTextActor.

virtual int vtkActor2D::IsA (  const char *    type )  [virtual]

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 vtkProp. Reimplemented in vtkCaptionActor2D, vtkCubeAxesActor2D, vtkLegendBoxActor, vtkXYPlotActor, vtkAxisActor2D, vtkParallelCoordinatesActor, vtkScalarBarActor, and vtkScaledTextActor.

vtkActor2D* vtkActor2D::SafeDownCast (  vtkObject *    o )  [static]

Will cast the supplied object to vtkObject* is this is a safe operation (i.e., a safe downcast); otherwise NULL is returned. This method is defined in all subclasses of vtkObject with the vtkTypeMacro found in vtkSetGet.h. Reimplemented from vtkProp. Reimplemented in vtkCaptionActor2D, vtkCubeAxesActor2D, vtkLegendBoxActor, vtkXYPlotActor, vtkAxisActor2D, vtkParallelCoordinatesActor, vtkScalarBarActor, and vtkScaledTextActor.

vtkActor2D* vtkActor2D::New (    )  [static]

Creates an actor2D with the following defaults: position (0,0) (coordinate system is viewport); at layer 0. Reimplemented from vtkProp. Reimplemented in vtkCaptionActor2D, vtkCubeAxesActor2D, vtkLegendBoxActor, vtkXYPlotActor, vtkAxisActor2D, vtkParallelCoordinatesActor, vtkScalarBarActor, and vtkScaledTextActor.

int vtkActor2D::RenderOverlay (  vtkViewport *    viewport )  [virtual]

int vtkActor2D::RenderOpaqueGeometry (  vtkViewport *    viewport )  [virtual]

Support the standard render methods. Reimplemented from vtkProp. Reimplemented in vtkCaptionActor2D, vtkCubeAxesActor2D, vtkLegendBoxActor, vtkXYPlotActor, vtkAxisActor2D, vtkParallelCoordinatesActor, vtkScalarBarActor, and vtkScaledTextActor.

int vtkActor2D::RenderTranslucentGeometry (  vtkViewport *    viewport )  [virtual]

Support the standard render methods. Reimplemented from vtkProp. Reimplemented in vtkCaptionActor2D, vtkCubeAxesActor2D, vtkLegendBoxActor, vtkXYPlotActor, vtkAxisActor2D, vtkParallelCoordinatesActor, vtkScalarBarActor, and vtkScaledTextActor.

void vtkActor2D::SetMapper (  vtkMapper2D *    mapper )

Set/Get the vtkMapper2D which defines the data to be drawn. Referenced by vtkScaledTextActor::LastOrigin().

virtual vtkMapper2D* vtkActor2D::GetMapper (    )  [virtual]

Set/Get the vtkMapper2D which defines the data to be drawn.

virtual void vtkActor2D::SetLayerNumber (  int    )  [virtual]

Set/Get the layer number in the overlay planes into which to render.

virtual int vtkActor2D::GetLayerNumber (    )  [virtual]

Set/Get the layer number in the overlay planes into which to render.

vtkProperty2D* vtkActor2D::GetProperty (    )

Returns this actor's vtkProperty2D. Creates a property if one doesn't already exist.

virtual void vtkActor2D::SetProperty (  vtkProperty2D *    )  [virtual]

Set this vtkProp's vtkProperty2D.

virtual vtkCoordinate* vtkActor2D::GetPositionCoordinate (    )  [virtual]

Get the PositionCoordinate instance of vtkCoordinate. This is used for for complicated or relative positioning. The position variable controls the lower left corner of the Actor2D

virtual void vtkActor2D::SetPosition (  float    x[2] )  [virtual]

Get the PositionCoordinate instance of vtkCoordinate. This is used for for complicated or relative positioning. The position variable controls the lower left corner of the Actor2D

virtual void vtkActor2D::SetPosition (  float    x, float    y )  [virtual]

virtual float* vtkActor2D::GetPosition (    )  [virtual]

Get the PositionCoordinate instance of vtkCoordinate. This is used for for complicated or relative positioning. The position variable controls the lower left corner of the Actor2D

void vtkActor2D::SetDisplayPosition (  int   , int    )

Set the Prop2D's position in display coordinates.

virtual vtkCoordinate* vtkActor2D::GetPosition2Coordinate (    )  [virtual]

Access the Position2 instance variable. This variable controls the upper right corner of the Actor2D. It is by default relative to Position and in normalized viewport coordinates. Some 2D actor subclasses ignore the position2 variable

virtual void vtkActor2D::SetPosition2 (  float    x[2] )  [virtual]

Access the Position2 instance variable. This variable controls the upper right corner of the Actor2D. It is by default relative to Position and in normalized viewport coordinates. Some 2D actor subclasses ignore the position2 variable

virtual void vtkActor2D::SetPosition2 (  float    x, float    y )  [virtual]
