Class FitsRectangle

java.lang.Object
  jfits.AbstractFitsShape
      jfits.FitsRectangle

All Implemented Interfaces:

Shape, FitsShape

public class FitsRectangle
extends AbstractFitsShape

This class represents a rectangular section in a fits file. The principal axis is defined to be along the longer side of the rectangle. The ADU value returned in getPrincipal(java.awt.geom.AffineTransform) is the average along the shorter axis.

Constructor Summary

FitsRectangle(Rectangle2D g)

Method Summary

List<Vector2D>	getPrincipal(AffineTransform a) We grab the list of all adus in our bounding rectangle, then define as the principal axis the longer one of the two sides.
boolean	isClosed() We are an open shape.

Method Detail

getPrincipal

public List<Vector2D> getPrincipal(AffineTransform a)
                            throws nom.tam.fits.FitsException

We grab the list of all adus in our bounding rectangle, then define as the principal axis the longer one of the two sides. For each pixel in this direction, we average along the secondary axis and return this average as the y component.

Parameters:

a - How the generic shape is transformed to FITS space.

Throws:

nom.tam.fits.FitsException

isClosed

public boolean isClosed()

We are an open shape.
