14 The ncarv_spool file contains definitions for spooled devices to be
15 used by ictrans. Each definition describes a rule used for sending a
16 set of metafile frames to a spooled device.
17 Each entry consists of a line of the form:
19 alias_name : translator_args : filter_chain
21 alias_name an identifier unique to the file. It is the alias
24 by which the definition may be referenced.
25 translator_args translator_args is a list of valid ctrans command
27 line arguments to be passed to ctrans. Metafile
28 frames are translated by ctrans and the output of
29 this translation is made available for further pro‐
30 cessing as specified by the remaining spooler defi‐
31 nition.
32 filter_chain is a set of simple commands separated by the UNIX
34 pipe symbol |. filter_chain may be terminated by
35 the UNIX file redirection symbols > or >> filename.
36 Output from ctrans is made available to the pro‐
37 cesses defined in filter_chain.
38 A pound-sign (#) as the first character indicates a comment line which
40 is ignored by routines that read this file. The order of entries in
41 ncarv_spool is important. If an alias name conflict arises the last
42 definition encountered is given precedence. Any previous definition for
43 the same alias name is discarded.
44
46 The following is an example ncarv_spool file. The first entry describes
47 a device named postscript. When postscript is named as the spooling
48 device, metafile frames are translated by ctrans into the format
49 described by the ps.mono graphcap. The font font1 is used for CGM text
50 elements. The result of this translation will be piped to lpr. The
51 second entry is named dicomed. The dicomed entry specifies that
52 metafile frames will be rasterized at a 1857 by 1183 pixel resolution
53 and output in X11 xwd format. The result of this rasterization is piped
54 to a program x11tonrif which in turn sends its output to a program
55 called rasttg. In the third example the final output is directed to a
56 file called sunfile.

70 If set this variable contains the path to the installed NCAR
71 Graphics libraries. NCARG_LIB overrides NCARG_ROOT.
