PROGRAM:

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
