# LuaScript

The Lua script to run to draw the overlay.

Specify one of the following:

- the absolute path to the Lua script file.
- the path to the Lua script file, relative to the LuaDirectory.
- a string that matches one of your `AdditionalDataLabels`, (if you use the `AdditionalData` and `AdditionalDataLabels` action parameters to upload the Lua script file as part of the Process action).

TIP: If your script is relatively short, for example a single line, you can set the parameter `LuaLine` instead of `LuaScript`. The `LuaLine` parameter allows you to specify a small amount of Lua code directly in the configuration file, removing the need for a separate script file.

The script must define a function with the name `draw`. The function is passed a `record` from the input track, for example:

    function draw(record)
      drawEllipse(record.FaceResult.face.ellipse, 3, rgb(255,255,255))
    end

For information about the Lua functions that you can use for drawing, see Drawing Functions.
