# 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"}
  ]
)
