All Implemented Interfaces:

Image, InterpolatedImage

public class InterpolatedRealColorImage

extends RealColorImage

implements InterpolatedImage

An InterpolatedRealColorImage is a RealColorImage that can be accessed at other than integral locations. Supports nearest neighbor, bilinear, and bicubic interpolation.

Field Summary

static int	CUBIC Bicubic constant
protected int	interpolationMethod The interpolation method that will be used.
static int	LINEAR Linear Interpolation constant
static int	NEIGHBOR Nearest neighbor constant
