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
