PROGRAM:
NAME
gml2gv,gv2gml - GML-DOT converters
SYNOPSIS
gml2gv [ -?v ] [ -ggname ] [ -ooutfile ] [ files ]
gv2gml [ -? ] [ -ooutfile ] [ files ]
DESCRIPTION
gml2gv converts a graph specified in the GML format to a graph in the GV (formerly DOT)
format. gv2gml converts a graph specified in the GV format to a graph in the GML format.
OPTIONS
The following options are supported:
-v Turns on verbose mode
-? Prints usage information and exits.
-ggname
The string gname is used as the name of the generated graph. If multiple graphs
are generated, subsequent graphs use the name gname appended with an integer.
-ooutfile
Prints output to the file outfile. If not given, gml2gv uses stdout.
OPERANDS
The following operand is supported:
files Names of files containing 1 or more graphs in GML. If no files operand is
specified, the standard input will be used.
RETURN CODES
Return 0 if there were no problems during conversion; and non-zero if any error occurred.
LIMITATIONS
As both the graph and graphics models of GV and GML differ significantly, the conversion
is at best approximate. In particular, it is not clear how multiedges are differentiated
in GML, so multiedges are created in GV with no user-available key. Also, no attribute
information is lost, in that any GML attributes that aren't converted to GV equivalents
are retained as attributes in the output graph.
At present, gv2gml does not support subgraphs and clusters. In addition, there does not
appear to be a standard mechanism for specifying default node and edge attributes in GML,
so any attributes are repeated for every node and edge.
