Constructor Summary

AdjustableVolumeTransform()
create a VolumeTransform that does a null transform between spaces of up to 2 dimensions

AdjustableVolumeTransform(int nax)
create a VolumeTransform that does a null transform between spaces of up to a given number of dimensions

AdjustableVolumeTransform(int inputNaxes, int outputNaxes)
create a VolumeTransform that does a null transform between spaces of a differing number number of dimensions

AdjustableVolumeTransform(Volume in, Volume out)
create the transform that will convert a given input Volume to a given output Volume.

AdjustableVolumeTransform(int inputNaxes, int outputNaxes, double[] trans, double[] scale, int[] order)
create a transform given a translation, scale, and axis order.

Method Summary

Constructor Detail

AdjustableVolumeTransform

public AdjustableVolumeTransform()

create a VolumeTransform that does a null transform between spaces of up to 2 dimensions

AdjustableVolumeTransform

public AdjustableVolumeTransform(int nax)

create a VolumeTransform that does a null transform between spaces of up to a given number of dimensions

AdjustableVolumeTransform

public AdjustableVolumeTransform(int inputNaxes,
                                 int outputNaxes)

create a VolumeTransform that does a null transform between spaces of a differing number number of dimensions

AdjustableVolumeTransform

public AdjustableVolumeTransform(Volume in,
                                 Volume out)

create the transform that will convert a given input Volume to a given output Volume.

AdjustableVolumeTransform

public AdjustableVolumeTransform(int inputNaxes,
                                 int outputNaxes,
                                 double[] trans,
                                 double[] scale,
                                 int[] order)
                          throws java.lang.IllegalArgumentException,
                                 java.lang.ArrayIndexOutOfBoundsException

create a transform given a translation, scale, and axis order. This version is prone to user error (in the specification of the axis order); VolumeTransform(Volume, Volume) should therefore be preferred. The meaning of input and output refers to that of the forward transform.

Parameters:

inputNaxes - the number of axes in the input space

outputNaxes - the number of axes in the input space

trans - the translation vector

scale - the scaling vector

order - the axis reordering

Throws:

java.lang.IllegalArgumentException - if an axis is repeated in the array.

java.lang.ArrayIndexOutOfBoundsException - if an axis index is out of range of [0, naxes-1], where naxes is the maximum of inputNaxes and outputNaxes.
