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.
