# edgepaint
> Colorize edges of a graph layout to clarify crossing edges.
> Graphviz filters: `acyclic`, `bcomps`, `comps`, `edgepaint`, `gvcolor`, `gvpack`, `mingle`, `nop`, `sccmap`, `tred`, & `unflatten`.
> More information: <https://graphviz.org/pdf/edgepaint.1.pdf>.
- Colorize edges of one or more graph layouts (that already have layout information) to clarify crossing edges:
`edgepaint {{path/to/layout1.gv}} {{path/to/layout2.gv ...}} > {{path/to/output.gv}}`
- Colorize edges using a color scheme. (See <https://graphviz.org/doc/info/colors.html#brewer>):
`edgepaint -color-scheme={{accent7}} {{path/to/layout.gv}} > {{path/to/output.gv}}`
- Lay out a graph and colorize its edges, then convert to a PNG image:
`dot {{path/to/input.gv}} | edgepaint | dot -T {{png}} > {{path/to/output.png}}`
- Display help:
`edgepaint -?`
