All Implemented Interfaces:

Operator

public class Mapper

extends SimpleOperator

Mapper applies a transformation (PointMapper) to an entire image.

Field Summary

static int	CUBIC Interpolation method types 3
static int	LINEAR Interpolation method types 2
protected float[]	m_defColor Backgroung color
private int	m_interpMethod Interpolation methods: neighbor, linear or cubic
private PointMapper	m_mapper Pointmapper object for transformation
static int	NEIGHBOR Interpolation method types 1

Constructor Summary

Mapper(PointMapper mapper, int interpolationMethod)
Constructs a Mapper object from a PointMapper object and an interpolation method.

Method Summary

protected Image	apply(ColorImage image) Applies the transformation to image through the PointMapper.
protected Image	apply(GrayImage image) Applies the transformation to image through the PointMapper.
protected Image	apply(RealColorImage image) Applies the transformation to image through the PointMapper.
protected Image	apply(RealGrayImage image) Applies the transformation to image through the PointMapper.
void	setDefaultColor(float[] color) set the color that will be use in apply() when out of bounds of the interpolated image.

Constructor Detail

Mapper

public Mapper(PointMapper mapper,
              int interpolationMethod)
       throws ImageNotSupportedException

Constructs a Mapper object from a PointMapper object and an interpolation method.

Parameters:

interpolationMethod - the way to interpolate (0=NEIGHBOR 1=LINEAR 2=CUBIC)

Method Detail

setDefaultColor

public void setDefaultColor(float[] color)

set the color that will be use in apply() when out of bounds of the interpolated image.

Parameters:

color - color to be used as default color. color will be used to the extent needed by the image type. For example, a GrayImage will return (int)color[0] for the default color, and RealColorImage will use the first three elements of color. If not enough elements are in the array, the last color will be repeated as needed.

apply

protected Image apply(GrayImage image)

Applies the transformation to image through the PointMapper. image is not modified.

Overrides:

apply in class SimpleOperator

Parameters:

image - GrayImage to map.

Returns:

a GrayImage object.

apply

protected Image apply(RealGrayImage image)

Applies the transformation to image through the PointMapper. image is not modified.

Overrides:

apply in class SimpleOperator

Parameters:

image - RealGrayImage to map.

Returns:

RealGrayImage.

apply

protected Image apply(ColorImage image)

Applies the transformation to image through the PointMapper. image is not modified.

Overrides:

apply in class SimpleOperator

Parameters:

image - ColorImage to map.

Returns:

ColorImage.

apply

protected Image apply(RealColorImage image)

Applies the transformation to image through the PointMapper. image is not modified.

Overrides:

apply in class SimpleOperator

Parameters:

image - RealColorImage to map.

Returns:

RealColorImage.
