Detailed Description

interpolate data values from images

vtkImageInterpolator provides a simple interface for interpolating image data. It provides linear, cubic, and nearest-neighbor interpolation.

Thanks:: Thanks to David Gobbi at the Seaman Family MR Centre and Dept. of Clinical Neurosciences, Foothills Medical Centre, Calgary, for providing this class.

Member Function Documentation

static vtkImageInterpolator* vtkImageInterpolator::New ( )

static

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

Reimplemented from vtkObject.

virtual const char* vtkImageInterpolator::GetClassName ( )

virtual

Reimplemented from vtkAbstractImageInterpolator.

static int vtkImageInterpolator::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 vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkAbstractImageInterpolator.

virtual int vtkImageInterpolator::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 vtkAbstractImageInterpolator.

static vtkImageInterpolator* vtkImageInterpolator::SafeDownCast ( vtkObject * o )

static

Reimplemented from vtkAbstractImageInterpolator.

virtual void vtkImageInterpolator::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 vtkAbstractImageInterpolator.

virtual void vtkImageInterpolator::SetInterpolationMode ( int mode )
