5.5. [IRAF.DEV]GRAPHCAP

There must be entries in the graphcap file for all graphics terminals, batch plotters, and image displays accessed by IRAF programs. New graphics terminals will need a new entry. The IRAF file gio$doc/gio.hlp contains documentation describing how to prepare graphcap device entries. A printed copy of this [60 page] document is available from the iraf/docs directory in the IRAF network archive. However, once IRAF is up you may find it easier to generate your own copy using help, as follows:

cl> help gio$doc/gio.hlp fi+ | lprint
which will print the document on the default IRAF printer device (use the "device=" hidden parameter to specify a different device). Alternatively, to view the file on the terminal,
cl> phelp gio$doc/gio.hlp fi+
The help pages for the IRAF tasks showcap and stty should also be reviewed as these utilities are useful for generating new graphcap entries. The i/o logging feature of stty is useful for determining exactly what characters your graphcap device entry is generating. The gdevices task is useful for printing summary information about the available graphics devices.
Help preparing new graphcap device entries is available if needed. We ask that new graphcap entries be sent back to us so that we may include them in the master graphcap file for all to benefit.
