Creating rainbow using Vix

Creating Rainbow. Quick introduction to working with complex numbers and its operations, mapim, buildlut.

There is non-interactive blog post version of the same here: Creating Rainbow using Vix 🌈 - *scratch*

I am thinking of writing few livebooks to showcase few core libvips operations that are powerful but lack discoverability or difficult to get the intuition. This is first in the direction. I’m writing as I’m trying to better understand concepts myself, so corrections or any type of feedbacks are welcome.

# Auto Correct Document Rotation

```elixir
Mix.install(
  [
    {:vix, "~> 0.17.0"},
    {:kino, "~> 0.9.2"}
  ],
  # pre-built binaries does not support fourier transform operations
  # since these operations depend on an additional library.
  #
  # Usually the platform/OS provided libvips comes with these additional library
  # so we are telling vix to use the libvips provided by the platform
  # and compile NIF for that. Follow platform specific libvips
  # installation guide
  system_env: [
    {"VIX_COMPILATION_MODE", "PLATFORM_PROVIDED_LIBVIPS"}
  ]
)
