NAME¶

gml2gv - GML-DOT converter

SYNOPSIS¶

gml2gv [ -? ] [ -ooutfile ] [ files ]

DESCRIPTION¶

gml2gv converts a graph specified in the GML format to a graph in the GV (formerly DOT) format.

OPTIONS¶

The following options are supported:

-?

Prints usage information and exits.

-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.
