net.ivoa.fits.data.ImageData

This class instantiates FITS primary HDU and IMAGE extension data. Essentially these data are a primitive multi-dimensional array.

Starting in version 0.9 of the FITS library, this routine allows users to defer the reading of images if the FITS data is being read from a file. An ImageTiler object is supplied which can return an arbitrary subset of the image as a one dimensional array -- suitable for manipulation by standard Java libraries. A call to the getData() method will still return a multi-dimensional array, but the image data will not be read until the user explicitly requests. it.

  public Data manufactureData() throws FitsException {
    return manufactureData(myHeader);
  }


  public static Data manufactureData(Header hdr) throws FitsException {
    return new ImageData(hdr);
  }

    return h;
  }


  /** Encapsulate an object as an ImageHDU. */
  public static Data encapsulate(Object o) throws FitsException {
    return new ImageData(o);
  }

      throws FitsException {
    ImageHDU ret;
    try {
      ImageTiler tiler = getTiler();
      Object tile = tiler.getTile(offset, size);
      ret = new ImageHDU(this.getHeader(), new ImageData(tile));


      Header retHeader = ret.getHeader();
      for (int i = 0; i < offset.length; i++) {
        retHeader.addValue(Header.NAXIS + (i + 1), size[i], "Axis "
            + (i + 1) + " size");
