"""Python interface to the Casacore images module.
A `casacore image <../../casacore/doc/html/group__Images__module.html>`_
represents an astronomical image of arbitrary dimensionality.
Several image formats are recognized:
`casacore paged image <../../casacore/doc/html/classcasa_1_1PagedImage.html>`_
is the native casacore image format stored in a casacore table.
`HDF5 <http://www.hdfgroup.org/HDF5>`_
is the HDF5 format often used in the earth science community.
`FITS <http://heasarc.gsfc.nasa.gov/docs/software/fitsio/fitsio.html>`_
is the well-known astronomical FITS format
`miriad <http://www.atnf.csiro.au/computing/software/miriad>`_
is the format used by the radio-astronomical MIRIAD package.
The following functionality exists:
- get and put data (slices)
- get or put a mask
- get meta data like coordinates and history
- get, put, or search optional image attributes (as used for LOFAR)
- get statistics
- form a subimage
- form an image expression which is treated as an ordinary image
- regrid the image
- write the image to a FITS file
