NAME
gvpack - merge and pack disjoint graphs
SYNOPSIS
gvpack [ -nguv? ] [ -mmargin ] [ -array[_flags][n] ] [
-ooutfile ] [ -Gname=value ] [ files ]
DESCRIPTION
gvpack reads in a stream of graphs, combines the graphs into
a single layout, and produces a single graph serving as the
union of the input graphs. The input graphs must be in dot
format, and must have all necessary layout information.
Acceptable input is produced by applying a Graphviz layout
program, such as dot or neato, with no -T flag.
By default, the packing is done at the cluster level. Thus,
parts of one graph will not intrude into any top-level clus-
ters or overlap any nodes or edges of another.
The output of gvpack can be used to produce concrete output
by applying neato -s -n2 with the desired -T flag.
OPTIONS
The following options are supported:
-g Combines the graphs at the graph level. This uses more
space, but prevents parts of one graph from occurring
between parts of another.
-array[_flags][n]
Combines the graphs at the graph level, placing them in
an array. By default, the layout is done in row-major
order. The number of columns used is roughly the square
root of the number of graphs. If the optional integer n
is supplied, this indicates the number of columns to
use.
followed
If optional flags are supplied, these consist of an
underscore
by any of the letters "c", "t", "b", "l", "r" or "u".
If "c" is supplied, the graphs are packed in column-
major order, in which case a final integer specifies
the number of rows. The flags "t", "b", "l", "r" indi-
cate that components are aligned along the top, bottom,
left or right, respectively. The "u" flag indicates
that the insertion order is based on the sortv
attribute attached to each graph.
-Gname=value

User Commands GVPACK(1)
Specifies attributes to be added to the resulting union
graph. For example, this can be used to specify a graph
label.
-mmargin
Packs the graphs allowing a margin of output points
around the parts.
-n Combines the graphs at the node level. Clusters are
ignored in the packing.
-ooutput
Prints output to the file output. If not given, gvpack
uses stdout.
-u Don't pack the graphs. Just combine them into a single
graph.
-v Verbose mode.
-? Prints usage information and exit.
OPERANDS
The following operand is supported:
files Names of files containing 1 or more graphs in dot
format. If no files operand is specified, the stan-
dard input will be used.
RETURN CODES
gvpack returns 0 if there were no problems, and non-zero
otherwise.
EXAMPLES
ccomps -x abc.gv | dot | gvpack | neato -s -n2 -Tps This
pipeline decomposes the graph in abc.gv into its connected
components, lays out each using dot, packs them all together
again, and produces the final drawing in PostScript. Of
course, there is nothing to prevent one from using different
layouts for each component.
BUGS
All the input graphs must be directed or undirected.
An input graph should not have a label, since this will be
used in its layout. Since gvpack ignores root graph labels,
resulting layout may contain some extra space.
gvpack unsets the bounding box attribute of all non-cluster
subgraphs.
