Fits (Flexible Image Transport System) is one solution. It is a standard
which allows floating point data, both single and double precision.

Goto sci.astro.fits for more information.

Perhaps this should be an FAQ?

Use NetCDF. It's available on both the systems you mention,
plus a great many others. Ftp into unidata.ucar.edu and
look in /pub/netcdf

Hello,

	I'm looking for info. on FITS (don't know what the acronynm stands

	is tremendously reducing the RAM requirements for the editing
	of high res. images. 

	Any information at all would be greatly appreciated.

A description of the PCX file format with C source code can be found in 
Practical Image Processing in C by Craig A Lindley.

FITS stands for Functional Interpolation Transformation System.  The
November 1993 issue of Advanced Imaging magazine has an article on a
commercial product called Live Picture, which uses FITS.

This is what I got, I don't know whether HIPS has other meanings :

Greeting:

    HIPS is partially released to public.  This is finally done.
    What is HIPS?  HIPS is a licensed image processing package.  The HIPS
image type covers almost all image formats, and it contributes thousands of
image processing tools.  So, this is exciting news for those people who are
looking for free non-byte grayscale image representation and tools.  Currently,
most common used free image types (formats) are:

	GIF, PICT, PNM (PBM, PGM, PPM), RLE, SunRaster, TIFF, even JPEG.

None of them supports non-byte grayscale image formats, such as

	SHORT, LONG, FLOAT, DOUBLE, COMPLEX and DOUBLE-COMPLEX formats.
Although, TIFF claim it is a flexible format, its new spec. still does not claim
the availability of non-byte grayscale image formats yet.  We knew many people
are looking for a free image software to handle non-byte grayscale formats.
Now, here you are.

    The HIPS public release lets people to freely use HIPS image representation,
but not HIPS image processing tools.  In other words, the public released HIPS
libraries allow you to read and write HIPS images, but you will not be able to
get all of those thousands of image processing software.

    Don't worry. If you feel you do like HIPS, you can either get a license
from Michael Landy ([email-masked]), or use CCS-ECL software in which the
free HIPS is included (CCS also goes with the standard HIPS distribution).

    Complex conversion system - extended C library (CCS-ECL) had its major
structure change.  Its structure is satable now.  Here is the description of
changes made from 1.0 - 1.1 - 1.2

    Release 1.1 - May 93
        The difference from release 1.0 - Ja1-92:
                Auto-Configuration System (ACS)
                JPEG memory management (v4)
                Tools - open to public - including:
                        Image-processing tools
                                3d-tools/
                                3dscale_geom/
                                convert/
                                getobj3d/
                                hips/
                                isobuild/
                                lut/
                                mahe/
                                tools/
                                ...
                        Network (server, RTP, ...)
                        Extended X server - getx
                                movie generater and player
                                image editor
                        3D segmentation and analysis (segal)
                        Virtual (Very) Fast Fourier Transform
    Release 1.2 - Dec. 2, 93
        The difference from release 1.1 - May 93
                Major I/O structure change (final)
                Modified ACS for JPEG v4 and v5
                HIPS partially open to public
                Table interface - completed

    Since CCS release 1.1 had bugs, it is no longer distributed.  Only the
original CCS and release 1.2 are under ~ftp/pub/ccs-ecl directory on

	george.lbl.gov (128.3.196.93) [ anonymous ]

there are:	ccs.tar.Z (orig) : ccs-1.2.tar.Z  and ccs-1.2-tool.tar.Z

There, you also can get free HIPS library  --  ~ftp/pub/hips_pub.tar.Z 
it will be there shortly because Mike (Michael Landy) will set up a ftp site
on his side (anonymous ftp on spoletta.cns.nyu.edu) and post announcement
after it is done.
