Constructor Detail

UndefinedHDU

public UndefinedHDU(Header h,
                    Data d)
             throws FitsException

Build an image HDU using the supplied data.

Parameters:

obj - the data used to build the image.

Throws:

FitsException - if there was a problem with the data.

Method Detail

isHeader

public static boolean isHeader(Header hdr)

isData

public static boolean isData(Object o)

Check if we can use the following object as in an Undefined FITS block. We allow this so long as computeSize can get a size. Note that computeSize may be wrong!

Parameters:

o - The Object being tested.

manufactureData

public Data manufactureData()
                     throws FitsException

Create a Data object to correspond to the header description.

Returns:

An unfilled Data object which can be used to read in the data for this HDU.

Throws:

FitsException - if the image extension could not be created.

manufactureData

public static Data manufactureData(Header hdr)
                            throws FitsException

Throws:

FitsException

manufactureHeader

public static Header manufactureHeader(Data d)
                                throws FitsException

Create a header that describes the given image data.

Parameters:

o - The image to be described.

Throws:

FitsException - if the object does not contain valid image data.

encapsulate

public static Data encapsulate(Object o)
                        throws FitsException

Encapsulate an object as an ImageHDU.

Throws:

FitsException

info

public void info()
