gvmap.sh

GVMAP.SH(1)						      General Commands Manual						       GVMAP.SH(1)

NAME

       gvmap.sh - pipeline for running gvmap

SYNOPSIS

       gvmap.sh [-vV?]	[ options ] [ -o outfile ] [ files ]

DESCRIPTION

       gvmap.sh  takes	as input a graph in DOT format, performs a layout, runs the output through gvmap and renders the output. At some point, it
       is hoped to integrate all of these tasks into gvmap.

OPTIONS

       The following options are supported:

       -a k   The integer k specifies the average number of artificial points added along the bounding box of the labels. Such	artificial  points
	      are  added  to  avoid a country boundary cutting through the boundary box of the labels. Computing time is proportional to k; hence,
	      for large graphs, a small value of k is suggested. If k = -1, a suitable value of k is automatically selected  based  on	the  graph
	      size. By default k = -1.

       -K layout
	      specifies  which	program  should  be use for the initial layout. By default, sfdp is run. Also by default, the layout is passed the
	      flag -Goverlap=prism. This can be overridden using a -g flag.

       -T format
	      specifies the final output format. This works the same way as the -T flag for any Graphviz layout program.

       -N attr=val
	      specifies the setting of a default node attribute during the rendering phase. This works the  same  way  as  the	-N  flag  for  any
	      Graphviz layout program.

       -G attr=val
	      specifies  the setting of a graph attribute during the rendering phase. This works the same way as the -G flag for any Graphviz lay-
	      out program.

       -E attr=val
	      specifies the setting of a default edge attribute during the rendering phase. This works the  same  way  as  the	-E  flag  for  any
	      Graphviz layout program.

       -n attr=val
	      specifies  the  setting of a default node attribute during the layout phase. This works the same way as the -N flag for any Graphviz
	      layout program.

       -g attr=val
	      specifies the setting of a graph attribute during the layout phase. This works the same way as the -G flag for any  Graphviz  layout
	      program.

       -e attr=val
	      specifies  the  setting of a default edge attribute during the layout phase. This works the same way as the -E flag for any Graphviz
	      layout program.

       -A flag
	      specifies a flag to be passed to gvmap. For example, gvmap.sh -Ae -As3 causes gvmap -e -s3 to be run.

       -v     Set verbose mode.

       -V     Print version information and exit.

       -?     Print usage information and exit.

EXAMPLES

       The following invocation creates a map with edges in semi-transparent light gray and nodes laid out using sfdp:

       gvmap.sh -Ae -Ecolor=#55555522 -Tpng foo.gv > foo.png

       It is equivalent to running the pipeline

       sfdp -Goverlap=prism foo.gv | gvmap -e | neato -n2 -Ecolor=#55555522 -Tpng > foo.png
