NAME

6       edgepaint - edge coloring to disambiguate crossing edges
7

SYNOPSIS

9       [ options ] [ -o outfile ] [ files ]
10

DESCRIPTION

12       edgepaint  takes  as input a graph in DOT format with node position in‐
13       formation (the pos attribute) and colors the edges in a  manner  making
14       it easier to tell them apart.
15

OPTIONS

17       The following options are supported:
18
19       -accuracy=e
20              accuracy with which to find the maximally different coloring for
21              each node with regard to its neighbors. Default e = 0.01.
22
23       -angle=a
24              color two edges differently if their  incidence  angle  is  less
25              than a degrees. Default a=15.
26
27       -random_seed=s
28              random  seed  to use. s must be an integer. If s is negative, we
29              do |s| iterations with different seeds and pick the best.
30
31       -lightness=l1,l2j
32              only applies for the "lab" color scheme: l1 and  l2  must  inte‐
33              gers, with 0 <= l1 <= l2 <=100. By default, we use "0,70"
34
35       -share_endpoint
36              if  this  option is specified, edges that shares an node are not
37              considered in conflict if they are close to parallel but are  on
38              the opposite sides of the node (around 180 degree).
39
40       -o f   write output to file f (default: stdout).
41
42       -color_scheme=c
43              specifies  the  color  scheme.  This can be "rgb", "gray", "lab"
44              (default); or a comma-separated list of RGB colors in hex (e.g.,
45              "#ff0000,#aabbed,#eeffaa")  representing  a palette; or a string
46              specifying  a  Brewer  color  scheme   (e.g.,   "accent7";   see
47              https://www.graphviz.org/doc/info/colors.html#brewer).
48
49       -v     turns on verbose mode.
50
51       -?     Print usage and exit.
52
53

BUGS

55       At  present,  edgepaint  does  not handle graphs with loops or directed
56       multiedges. So, a graph with edges a -> b and b -> a is acceptable, but
57       not  if  it has edges a -> b and a -> b or a -- b and a -- b. Ports are
58       ignored in this analysis, so having a.x -> b and a.y -> b is  also  not
59       supported.
