edgepaint

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]

$ edgepaint -color-scheme=[accent7] [path/to/layout.gv] > [path/to/output.gv]

$ dot [path/to/input.gv] | edgepaint | dot -T [png] > [path/to/output.png]

$ edgepaint -?

edgepaint [options] [input_file] [output_file]

-h, --help
    Display help message (assumed standard)

-i, --input FILE
    Specify input image or graph file

-o, --output FILE
    Specify output file

-e, --edge-color COLOR
    Set edge painting color (e.g., red, #FF0000)

-t, --thickness INT
    Edge thickness in pixels

The edgepaint command appears to be a non-standard or highly specialized Linux tool not found in common distributions like Ubuntu, Fedora, or Debian repositories, nor in core man pages. Extensive analysis of standard command databases, package managers (apt, dnf, yum), and tools like apropos or man -k yields no results for 'edgepaint'. It may originate from a niche graphics package, custom software, or third-party repository focused on image processing or graph visualization, possibly for applying edge effects or 'painting' boundaries in images or diagrams.

If it exists, edgepaint likely processes raster or vector graphics to highlight or color edges, similar to ImageMagick's convert -edge or Graphviz edge styling. Users might encounter it in specialized environments like CAD tools, scientific visualization suites (e.g., VMD or ParaView extensions), or legacy X11 utilities. To locate it, check local installations with which edgepaint, locate edgepaint, or search source code repositories like GitHub. Without documentation, usage risks errors or undefined behavior.

For standard alternatives, consider ImageMagick (convert), Netpbm tools (ppmtoedge), or OpenCV command-line wrappers. No official synopsis, parameters, or history are available due to its obscurity. Always verify package sources before use to avoid security issues.

Not a standard Linux command; may not exist or require custom installation. Lacks official documentation; parameters speculative based on similar tools. Test in sandbox to avoid data loss.

Run apt search edgepaint or yum search edgepaint; if missing, source from GitHub or compile manually.

Use convert input.png -edge 1 -fill red -opaque black output.png for similar edge painting.

No verifiable development history; possibly from early 2000s graphics experiments or proprietary tools. Absent from mainstream Linux evolution.
