NAME
edgepaint - edge coloring to disambiguate crossing edges
SYNOPSIS
[ options ] [ -o outfile ] [ files ]
DESCRIPTION
edgepaint 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,l2
Only applies for the "lab" color scheme: l1 and l2 must
integers, with 0 <= l1 <= l2 <=100. By default, we use "0,70".
--share_endpoint
If this option is specified, edges that share a 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
https://graphviz.org/doc/info/colors.html#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. Ports are
ignored in this analysis, so having a.x -> b and a.y -> b is also not
supported.
