-callback 

The parent process is contacted after each relayout by the X11 event ClientMessage (Unix) or by Windows interprocess communication routines. Communication between the parent process and aiSee doesn't work unless aiSee was started with the option -x11msg (Unix) or -ddemsg (Windows).

-canim

Animates the crossing reduction heuristics, see animation after relayout.

-cedges

The edges are anchored at the nodes so that they point to the center of the nodes. Port sharing is switched off and the edge arrow head style free is used.

-cmax Int

Sets the maximum number of iterations of the crossing reduction phase. A reduction of this value causes the layout process to be speeded up. The default value is infinite meaning that the method is iterated as long as any improvement is possible. The corresponding GDL graph attribute is cmax.

-cmin Int

Sets the minimum number of iterations that are performed for reducing crossings using crossing weights. The normal method stops when two consecutive checks no longer cause the number of crossings to be reduced. However, this number of crossings might be a local minimum, meaning the number of crossing might decrease even more after some more iterations. The corresponding GDL graph attribute is cmin.

-color

The output file contains a colored graph. This option is useful for PostScript or SVG output only, see -psoutput and -svgoutput.

-d Algorithm

Specifies the Algorithm to be used for graph layout. The default value is normal. The corresponding GDL graph attribute is layout_algorithm. For the available algorithms, see also GDL in a Nutshell.

-ddemsg

Enables interprocess communication in a client-server fashion with an application program via a DDE channel. Useful for the Windows version of aiSee only. Unix users please see -x11msg.

-display H:D 

Specifies the X11 server (Host:Display) to be contacted. This option is useful for Unix versions of aiSee only.

-edgepoly

Used in combination with -gdloutput. Forces bent edges to be output in one go in the GDL output, i.e., no dummy nodes for the bent points are introduced.

-epanim

Animates the positioning heuristics (extended mode), see animation after relayout.

-error Int 

Stops aiSee after Int errors while parsing the specification. The default value is 16.
