GVMAP.SH(1)            DragonFly 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
              layout 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
