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
