gvmap.sh - pipeline for running gvmap
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
