Member Function Documentation

static vtkRayCastImageDisplayHelper* vtkRayCastImageDisplayHelper::New (  )  [static]

Create an object with Debug turned off, modified time initialized to zero, and reference counting on.

Reimplemented from vtkObject.

Reimplemented in vtkMesaRayCastImageDisplayHelper, and vtkOpenGLRayCastImageDisplayHelper.

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

static int vtkRayCastImageDisplayHelper::IsTypeOf ( const char *  name  )  [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 vtkTypeRevisionMacro found in vtkSetGet.h.

Reimplemented from vtkObject.

Reimplemented in vtkMesaRayCastImageDisplayHelper, and vtkOpenGLRayCastImageDisplayHelper.

virtual int vtkRayCastImageDisplayHelper::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 vtkTypeRevisionMacro found in vtkSetGet.h.

Reimplemented from vtkObject.

Reimplemented in vtkMesaRayCastImageDisplayHelper, and vtkOpenGLRayCastImageDisplayHelper.

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

virtual void vtkRayCastImageDisplayHelper::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 vtkObject.

Reimplemented in vtkMesaRayCastImageDisplayHelper, and vtkOpenGLRayCastImageDisplayHelper.

virtual void vtkRayCastImageDisplayHelper::SetPixelScale ( float   )  [virtual]

Set / Get the pixel scale to be applied to the image before display. Can be set to scale the incoming pixel values - for example the fixed point mapper uses the unsigned short API but with 15 bit values so needs a scale of 2.0.

Set / Get the pixel scale to be applied to the image before display. Can be set to scale the incoming pixel values - for example the fixed point mapper uses the unsigned short API but with 15 bit values so needs a scale of 2.0.
