public class LinearCoordinateSystem
extends CoordinateSystem

a description of a world coordinate system made up of any number of simple linear axes.

##

LinearCoordinateSystem(int)
  construct a coordinate system with the specified number of linear axes.
LinearCoordinateSystem(int, Metadata)
  construct a coordinate system with the specified number of axes and described by the specified set of Metadata.
LinearCoordinateSystem(int, Metadata, double[], double[], double[], double[], String[])
  create a LinearCoordinateSystem object specifying all internal data.
LinearCoordinateSystem(Metadata)
  construct a coordinate system described by the specified set of Metadata.

LinearCoordinateSystem

      public LinearCoordinateSystem(int naxes)

  construct a coordinate system with the specified number of linear axes.

LinearCoordinateSystem

      public LinearCoordinateSystem(int naxes,
                                    Metadata md) throws IllegalTransformException

  construct a coordinate system with the specified number of axes and described by the specified set of Metadata. The Metadata is examined to determine the paramters of the system, including which of the axes define the spherical portion of the system.

LinearCoordinateSystem

      public LinearCoordinateSystem(Metadata md) throws IllegalTransformException

  construct a coordinate system described by the specified set of Metadata. The Metadata is examined to determine the paramters of the system, including which of the axes define the spherical portion of the system.

LinearCoordinateSystem

      public LinearCoordinateSystem(int naxes,
                                    Metadata md,
                                    double refpos[],
                                    double refoff[],
                                    double refval[],
                                    double stepsz[],
                                    String names[]) throws IllegalTransformException

  create a LinearCoordinateSystem object specifying all internal data. Missing values in the input array are set to default values.
  Parameters:
    naxes - the maximum number of axes this transform can operate on
    md - metadata describing the coordinate system; data in this list are overridden by the other data given in this constructor
    refpos - the position in the "input" system (the system forward() transforms from) that is equal to the the refval position. Default equals 0.
    refval - the position in the "output" system (the system forward() transforms to) that is equal to the the refpos position. Default equals 0.
    refoff - An extra offset that gets added to the reference position. Default equals 0;
    stepsz - the size of a voxel of the "output" system (the system that forward() transforms to) in units of the "input" system
    names - names to assign to transformed axes. A null element of null array means do not reassign name. These values only affect the behavior of getMetadata();
  Throws: IllegalTransformException
    if the parameters do not define a valid transformation.
