    I want to read about various image formats like TIFF/GIFF etc...
    Where can I get them?

The FITS (Flexible Image Transport System) data format.

FITS (Flexible Image Transport System) is a data format designed to
allow convenient exchange of astronomical data between installations
whose standard internal formats and hardware may be different.  The
"Image" in the name comes from the original use of the format to
transport digital images, but it's not just for images any more.

The NOST maintains a file of FITS information available by 
anonymous ftp from nssdca.gsfc.nasa.gov or DECnet copy from NSSDCA, in 
the directory FITS. It includes copies of the current draft NASA Standard 
in flat ASCII, PostScript, and LaTeX, and a list of the current 
extension type (structure) names registered with the IAU FITS Working 
Group.  It also contains, in LaTeX form, the text of the proposal for 
one of these new extension types, IMAGE.  A README. file describes the 
contents of the directory.  There is a further subdirectory, SOFTWARE, 
described by README.FIRST, containing a program in C to read and list 
the headers of a FITS file and another file with information on 
publicly available FITS software packages.

Beware that this is a VMS system, and that files should be gotten with
commands of the form:

	get [.FITS]XTENSION.LIS

One sophisticated general purpose PD FITS software package is FITSIO
by Bill Pence at Goddard Space Flight Center. It is in
/pub/fitsio3/*@tetra.gsfc.nasa.gov. FITSIO is portable to a variety of
OSes. In general, writing images to FITS format is an easy problem.

FITS documents are available from

* Menu:

* NRAO: (FTP:fits.cx.nrao.edu:/FITS/*)*
* ESO: (FTP:ftphost.hq.eso.org:/fits/*)*

* Usenet: (USENET:sci.astro.fits)*

* FitsImaging::
	Viewer for FITS images on X windows.

* FitsIO::
	Fortran subroutine interface for FITS files.
