Hi I want to represent a binary (0-1) array in the form of an image. E.g. if A[1,1] = 1, then square [1,1[would be represented as black colored square otherwise it will be represented as white colored square if A[1,1] = 0.

Please tell me what packages to use and how code should be written

```julia
using Images, Random
Gray.(bitrand(10, 10))

```

If you’re using Juno or IJulia, this should just show up as an image. Or you can use ImageView. There are extensive docs at [Home · JuliaImages](https://juliaimages.org/latest/).

Note that in Julia and every other language I know of, true = 1 = white and false = 0 = black.
