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.

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.

◆ SetPixelScale()

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.
