gvmap.sh - Man Page

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

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.

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.

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
