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.
