private AffineTransform	last Cache last requests for speedup.

Constructor Summary

Constructor Detail

AbstractFitsShape

protected AbstractFitsShape(Shape like)

Constructs a new abstract fits shape specifiying the generic shape.

AbstractFitsShape

protected AbstractFitsShape(nom.tam.fits.Fits fits,
                            Shape like)
                     throws nom.tam.fits.FitsException

Constructs a new abstract fits shape specifiying the fits object and the generic shape. Always uses the first image HDU found in the image. If that is not the intended behaviour, either use the constructor with the ImageHDU specified, or register the image hdu later.

Throws:

nom.tam.fits.FitsException

AbstractFitsShape

protected AbstractFitsShape(nom.tam.fits.ImageHDU fits,
                            Shape like)
                     throws nom.tam.fits.FitsException

Constructs a new abstract fits shape specifiying the fits object and the generic shape. Always uses the first image HDU found in the image. If that is not the intended behaviour, either use the constructor with the ImageHDU specified, or register the image hdu later.

Throws:

nom.tam.fits.FitsException

registerFits

public void registerFits(nom.tam.fits.Fits i)
                  throws nom.tam.fits.FitsException

Registers a fits object. This method scans for the first valid image HDU and uses this as the base. If this behaviour is not intended, use the image-hdu specific method.

Specified by:

registerFits in interface FitsShape

Throws:

nom.tam.fits.FitsException

registerFits

public void registerFits(nom.tam.fits.ImageHDU i)
                  throws nom.tam.fits.FitsException

Registers the image data to this shape.

Specified by:

registerFits in interface FitsShape

Throws:

nom.tam.fits.FitsException

See Also:

FitsShape.registerFits(Fits)

getStatistic

public Statistic getStatistic(AffineTransform at)
                       throws nom.tam.fits.FitsException

Generates the statistic out of the specified transform.

Specified by:

getStatistic in interface FitsShape

Parameters:

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

Throws:

nom.tam.fits.FitsException

getAdus

public List<Vector3D> getAdus(AffineTransform at)
                       throws nom.tam.fits.FitsException

Transforms the generic shape to match the FITS geometry, then greps all underlying adus whose central coordinate (image+0.5, FITS convention -0.5) lies within the shape.

Specified by:

getAdus in interface FitsShape

Parameters:

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

Throws:

nom.tam.fits.FitsException

getFitsShape

protected Shape getFitsShape(AffineTransform at)

We use the user-supplied transform to get a true shape that can be applied to ther underlying fits. If no transform was specified, we use the generic shape as-is, which is probably not what you want.
