Method Detail

getName

public java.lang.String getName()

Get the name of the compontent

getDescription

public java.lang.String getDescription()

Return a description of the component

inverse

public Deprojecter inverse()

Get the inverse transformation

Specified by:

inverse in class Projecter

isInverse

public boolean isInverse(Transformer t)

Is this an inverse of some other transformation?

Specified by:

isInverse in class Transformer

transform

public final void transform(double[] sphere,
                            double[] plane)

Do the transformation

Specified by:

transform in class Transformer

Parameters:

sphere - The input vector.

plane - The output vector, it may be the same as the input vector if the dimensionalities are the same. All transformers are expected to work with aliased inputs and output.

validPosition

public boolean validPosition(double[] plane)

Description copied from class: Projecter

Is this a valid position in the projection plane for this image. This default is appropriate for all projections where the projection plane is infinite.

Overrides:
