-landscape

Selects landscape orientation for export of graphs to PostScript. See also -portrait.

-latelabels

Controls the moment when edge labels are drawn. With this option, the graph is first partitioned and then edge labels are introduced. Otherwise, the algorithm first creates labels and then partitions the graph, which yields a more compact layout but may result in more crossings. The corresponding GDL graph attribute is late_edge_labels.

-linseg

Switches linear segment layout on. This layout favors straight long vertical edges. The corresponding GDL graph attribute is linear_segments. See also -linsegmax and -nolinseg.

-linsegmax Int

Specifies the maximum length of a vertical linear edge segment, i.e. maximum number of levels a linear segment crosses without any bending. The default value is infinite.

-lm Float Unit 

Sets the left margin of the output to Float Units. No right margin may be specified otherwise this option doesn't work. The graph is centered on the page by default. This option is useful only if the graph fits on the page. For the available Units, see -width.

-multi F1 ... FN 

Reads the files F1 ... FN one after another to display a sequence of graphs. The first graph is visualized and displayed. To see the next graph in the sequence, the user must choose Next File from the File menu.

-manhattan

Switches Manhattan Layout on, meaning that all edges consist of horizontal or vertical line segments. Vertical edge segments might be shared by several edges, while horizontal edge segments are never shared. This results in aesthetic layouts for flowcharts and looks nice for trees, tree-like graphs, and data structs. The corresponding GDL graph attribute is manhattan_edges. If Manhattan Layout is used, the priority phase and straight phase are also used by default, meaning that this option implies -prio -straight. These phases can be explicitly switched off by using -noprio and -nostraight.

-maxspect

Scales a graph so that the entire graph fits into the aiSee browser window. The corresponding GDL specification is scaling: maxspect.

-median

Uses median center for calculating the weights during crossing reduction. The corresponding GDL specification is crossing_weight: median. See also -bary, -barymedian, and -medianbary.

-medianbary 

Uses a combination of barycenter and mediancenter weights during crossing reduction, with the mediancenter having priority. The corresponding GDL specification is crossing_weight: medianbary. See also -bary, -barymedian, and -median.
