Using the /imagine command

    client = UserapiAi::Client.new(service: :midjourney)
    result = client.imagine(prompt: "nice girl")
    or
    result = client.imagine(prompt: "nice girl",
                            webhook_url: "https://example.com/imagine/webhook-url",
                            webhook_type: "progress", # or result
                            account_hash: "a7d44910-88a6-4673-acc8-d60ffc3479a6",
                            is_disable_prefilter: false)
    then
    client.status(result)

Examples of other commands with parameters

    result = client.status(hash: "xxx-xxx")
    result = client.variation(hash: "xxx-xxx", choice: 1)
    result = client.upsample(hash: "xxx-xxx", choice: "v6_2x_subtle")

    result = client.upscale(hash: "xxx-xxx", 
                            choice: 1,
                            webhook_url:  "https://example.com/upscale/webhook-url",

Magick Tools

You can split the quad-layout output from Midjourney into 4 separate images.

gem "mini_magick"

    response = client.status result
    if response["status"] == "done"
      local_paths = UserapiAi::Tool.crop result: response["result"] 
      # or UserapiAi::Tool.crop url: "https://example.com/img.png"
      local_paths.each do |path|
           f = File.open(path)
           ...
        end
    end
