SYNOPSIS
[ options ] [ -o outfile ] [ files ]
DESCRIPTIONedgepaint takes as input a graph in DOT format with node position
information (the pos attribute) and colors the edges in a manner making
it easier to tell them apart.
OPTIONS
The following options are supported:
-accuracy=e
accuracy with which to find the maximally different coloring for
each node with regard to its neighbors. Default e = 0.01.
-angle=a
color two edges differently if their incidence angle is less
than a degrees. Default a=15.
-random_seed=s
random seed to use. s must be an integer. If s is negative, we
do |s| iterations with different seeds and pick the best.
-lightness=l1,l2j
only applies for the "lab" color scheme: l1 and l2 must inte‐
gers, with 0 <= l1 <= l2 <=100. By default, we use "0,70"
-share_endpoint
if this option is specified, edges that shares an node are not
considered in conflict if they are close to parallel but are on
the opposite sides of the node (around 180 degree).
-o f write output to file f (default: stdout).
-color_scheme=c
specifies the color scheme. This can be "rgb", "gray", "lab"
(default); or a comma-separated list of RGB colors in hex (e.g.,
"#ff0000,#aabbed,#eeffaa") representing a palette; or a string
specifying a Brewer color scheme (e.g., "accent7"; see
http://www.graphviz.org/content/color-names#brewer).
-v turns on verbose mode.
-? Print usage and exit.
BUGS
At present, edgepaint does not handle graphs with loops or directed
multiedges. So, a graph with edges a -> b and b -> a is acceptable, but
not if it has edges a -> b and a -> b or a -- b and a -- b.
