Abstract:	The Client Display Library is a new interface that allows host (non-IRAF) C or \fortran\/ programs to display images or draw into the graphics overlay using the XImtool image server and image viewers which emulate the XImtool client protocol such as SAOtng, SAOimage, and IPAC Skyview. The CDL provides most of the algorithms and functionality found in standard IRAF tasks such as DISPLAY and TVMARK, but provides these in library form for use in host level user programs, much as the IMFORT library provides access to IRAF images on disk. High-level procedures allow simple display of IRAF and FITS images, automatic image scaling, and a wide variety of graphics markers and scalable text. The IIS protocol used is easily replaced allowing the library to be ported for use with other display servers.
