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,l2j
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 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.
