This directory contains the Client Display Library (CDL) sources.
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.
This package is made up of several interfaces, specifically
CDL - high-level image display and graphics overlay
IMD - mid-level image display routines
COMM - server communications (currently IIS)
See the Notes file or Reference Guide in the doc subdirectory for more information.
Source for the library itself is in this directory. Documentation
is in the 'doc' subdirectory and demonstration applications can be found in the 'examples' subdirectory. The 'test' subdirectory contains debugging programs used during development; they're not really good examples of programming practice but may serve as demos of how individual functions can be called.
See the RELEASE.NOTES file in this directory, or the Reference
Guide in the 'doc' subdirectory for information on using and installing this library.
