Detailed Description

An actor that displays text.

The input text is rendered into a buffer, which in turn is used as a texture applied onto a quad (a vtkImageActor is used under the hood).

Warning
This class is experimental at the moment.
  • The orientation is not optimized, the quad should be oriented, not the text itself when it is rendered in the buffer (we end up with excessively big textures for 45 degrees angles). This will be fixed first.
  • No checking is done at the moment regarding hardware texture size limits.
  • Alignment is not supported (soon).
  • Multiline is not supported.
  • Need to fix angle out of 0<->360

Member Function Documentation

static vtkTextActor3D* vtkTextActor3D::New ( )
static
virtual const char* vtkTextActor3D::GetClassName ( )
virtual

Reimplemented from vtkProp3D.

static int vtkTextActor3D::IsTypeOf ( const char *  type)
static
virtual int vtkTextActor3D::IsA ( const char *  name)
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 vtkProp3D.

static vtkTextActor3D* vtkTextActor3D::SafeDownCast ( vtkObject o)
static
void vtkTextActor3D::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 vtkProp3D.

virtual void vtkTextActor3D::SetInput ( const char *  )
virtual

Set the text string to be displayed.

virtual char* vtkTextActor3D::GetInput ( )
virtual

Set the text string to be displayed.

virtual void vtkTextActor3D::SetTextProperty ( vtkTextProperty p)
virtual

Set/Get the text property.

virtual vtkTextProperty* vtkTextActor3D::GetTextProperty ( )
virtual

Set/Get the text property.

void vtkTextActor3D::ShallowCopy ( vtkProp prop)
virtual

Shallow copy of this text actor. Overloads the virtual vtkProp method.

Reimplemented from vtkProp3D.

virtual double* vtkTextActor3D::GetBounds ( )
virtual

Get the bounds for this Prop3D as (Xmin,Xmax,Ymin,Ymax,Zmin,Zmax). These are the padded-to-power-of-two texture bounds.

Implements vtkProp3D.

int vtkTextActor3D::GetBoundingBox ( int  bbox[4])

Get the Freetype-derived real bounding box for the given vtkTextProperty and text string str. Results are returned in the four element bbox int array. This call can be used for sizing other elements.

virtual void vtkTextActor3D::ReleaseGraphicsResources ( vtkWindow )
virtual

WARNING: INTERNAL METHOD - NOT INTENDED FOR GENERAL USE DO NOT USE THIS METHOD OUTSIDE OF THE RENDERING PROCESS. Release any graphics resources that are being consumed by this actor. The parameter window could be used to determine which graphic resources to release.

Reimplemented from vtkProp.

int vtkTextActor3D::RenderOpaqueGeometry ( vtkViewport viewport)
virtual

WARNING: INTERNAL METHOD - NOT INTENDED FOR GENERAL USE DO NOT USE THIS METHOD OUTSIDE OF THE RENDERING PROCESS. Draw the text actor to the screen.

Reimplemented from vtkProp.
