Class Uimage

com.c3d.image.Uimage

public abstract class Uimage

implements com.c3d.structured.Subscriptable

TeX The class Uimage\footnote{\copyright Turing Institute, 1998} is an abstract class to support operations on 2 dimensional arrays of objects.

Field Summary

int	height TeX The number of pixels high and wide that the image occupies.
int	planes TeX The number of pixels high and wide that the image occupies.
java.util.Hashtable	properties TeX required by image consumer but not used
int	width TeX The number of pixels high and wide that the image occupies.

Constructor Summary

Uimage()

Method Summary

int	arity()
double	cardinality()
boolean	lessthan(com.c3d.util.atomic.Universal b) TeX one image less than another if all pixels less than corresponding ones, thus it can be implemented by injecting $<$ between the elements of a and b, and then applying $\times/$ to the result
abstract com.c3d.util.atomic.Universal	pixel(int x, int y, int plane)
void	setProperties(java.util.Hashtable props)
abstract Uimage	subImage(int x, int y, int dx, int dy)
com.c3d.util.atomic.Universal	subscript(com.c3d.util.atomic.Universal I) TeX Subscription by a number returns the Ith data element of the image.

Field Detail

height

public int height

TeX The number of pixels high and wide that the image occupies.

width

public int width

TeX The number of pixels high and wide that the image occupies.

planes

public int planes

TeX The number of pixels high and wide that the image occupies.

public java.util.Hashtable properties

TeX required by image consumer but not used

Constructor Detail

Uimage

public Uimage()

Method Detail

pixel

public abstract com.c3d.util.atomic.Universal pixel(int x,
                                                    int y,
                                                    int plane)

subImage

public abstract Uimage subImage(int x,
                                int y,
                                int dx,
                                int dy)

setProperties

public void setProperties(java.util.Hashtable props)

subscript

public com.c3d.util.atomic.Universal subscript(com.c3d.util.atomic.Universal I)

TeX Subscription by a number returns the Ith data element of the image. Subscription by a 3tuple returns the pixel at position [plane,x,y]. All other case raise an array bounds exception.

Specified by:

subscript in interface com.c3d.structured.Subscriptable

arity

public int arity()

Specified by:

arity in interface com.c3d.structured.Subscriptable

cardinality

public double cardinality()

lessthan

public boolean lessthan(com.c3d.util.atomic.Universal b)

TeX one image less than another if all pixels less than corresponding ones, thus it can be implemented by injecting $<$ between the elements of a and b, and then applying $\times/$ to the result
