Detailed Description

represents an image (data & properties) in a rendered scene.

vtkImageActor is used to render an image in a 3D scene. The image is placed at the origin of the image, and its size is controlled by the image dimensions and image spacing. The orientation of the image is orthogonal to one of the x-y-z axes depending on which plane the image is defined in. vtkImageActor duplicates the functionality of combinations of other VTK classes in a convenient, single class.

Member Function Documentation

float* vtkImageActor::GetBounds   [virtual]
 

Get the bounds of this image actor. Either copy the bounds into a user provided array or return a pointer to an array. In either case the boudns is expressed as a 6-vector (xmin,xmax, ymin,ymax, zmin,zmax).

Reimplemented from vtkProp.

virtual const char* vtkImageActor::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 vtkMesaImageActor.

virtual int vtkImageActor::GetInterpolate   [virtual]
 

Turn on/off linear interpolation of the image when rendering.

int vtkImageActor::GetSliceNumber  
 

Return a slice number computed from the display extent.

virtual int vtkImageActor::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 vtkMesaImageActor.

int vtkImageActor::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 vtkMesaImageActor.

vtkImageActor* vtkImageActor::New   [static]
 

Instantiate the image actor.

Reimplemented from vtkProp.

Reimplemented in vtkMesaImageActor.

void vtkImageActor::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.

int vtkImageActor::RenderOpaqueGeometry vtkViewport   viewport [virtual]
 

WARNING: INTERNAL METHOD - NOT INTENDED FOR GENERAL USE DO NOT USE THIS METHOD OUTSIDE OF THE RENDERING PROCESS Support the standard render methods. int RenderTranslucentGeometry(vtkViewport *viewport);

Reimplemented from vtkProp.

vtkImageActor* vtkImageActor::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 vtkMesaImageActor.

void vtkImageActor::SetDisplayExtent int    extent[6]
 

The image extent is generally set explicitly, but if not set it will be determined from the input image data.

virtual void vtkImageActor::SetInput vtkImageData   [virtual]
 

Set/Get the image data input for the image actor.
