goart
Generate art on the command line.

This command-line utility, goart, began as a fork of the companion source code to the book, "Generative Art in Go.", which intended to introduce novice and experienced programmers to algorithmic art. It did just that for me, and I decided to convert the code into a command-line utility and being modifying the code to do even more.

$ goart --help
Generates art using a source image as the starting point.

        The resulting image can be further manipulated with flags to this
        command.

Usage:
  goart generate FILE [flags]

Flags:
  -A, --alpha-increase float               the step of transparency increase at each iteration (default 0.06)
  -H, --height int                         height of the generated image (default 2000)
  -h, --help                               help for generate
  -a, --initial-alpha float                beginning stroke transparency (default 0.1)
  -K, --keep-source-dimensions             generate a new image with the same dimensions as the source image (default true)
  -M, --max-edge int                       maximum stroke will be a n-edge polygon (4 is a square) (default 4)
  -m, --min-edge int                       minimum stroke will be a n-edge polygon (3 is a triangle) (default 3)
  -z, --random                             generates a new image using a random one pulled from source.unsplash.com
  -t, --stroke-inversion-threshold float   the minimum stroke size (default 0.05)
  -j, --stroke-jitter float                deviation of the colored stroke from its projected position in the original image (default 0.1)
  -r, --stroke-ratio float                 size of the initial stroke compared to that of the final result (default 0.75)
  -R, --stroke-reduction float             the initial stroke size gets minimized by this amount on each iteration (default 0.002)
  -T, --total-cycles int                   Copy any discovered k8s squashfs images from SRC to DEST (default 5000)
  -W, --width int                          width of the generated image (default 2000)

Global Flags:
      --config string   config file (default is $HOME/.goart.yaml)
      --viper           use Viper for configuration (default true)
