Client Display Library (CDL) V1.6 Released
------------------------------------------

	A new version of the IRAF Client Display Library (CDL) is now
available.  The CDL is a  host interface for C or Fortran programs
allowing them to display images or overlay graphics to display servers
such as XImtool or SAOimage / SAOtng.  High-level procedures allow IRAF or
FITS images to be displayed simply, other routines permit access to all
other server functions (e.g. cursor and image readback, frame selection,
etc).  The library also features a number of functions for doing image
overlay graphics; supported graphics primitives include numerous point
shapes, lines, circles, ellipses, polygons, annular shapes, and text.

	The initial CDL release provided most of the functionality
required for image display or graphic overlay clients, since then a number
of new features have evolved that were needed.  The V1.6 version number
reflects the stop-and-start nature of this work, more work is planned but
a release of the new version is long overdue.  New features include:

        o  Support for the new V2.11 IRAF OIF image format
        o  A prototype SPP language binding
        o  Full ANSI C function prototype support
        o  Support for variable line widths
        o  A selection of "dashed" line styles for polyline/polygon markers
        o  A selection of text fonts including
                ROMAN           FUTURA          TIMES
                GREEK           BOLD
        o  Sub/Superscripting text
        o  In-line font changes
        o  Support for text line widths
        o  A "virtual" display server that may also be used as a 'proxy'
           server providing an image display "tee" functionality
        o  Numerous bug fixes

See the CDL Reference Guide in the 'doc' subdirectory for details on new
features, and the RELEASE-1.6.NOTES file for installation information.
