LuaScript
The Lua script to run to draw on the source images or video frames.
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 theAdditionalDataandAdditionalDataLabelsaction 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.FaceResultAndImage.face.ellipse, 3, rgb(255,255,255)) end
For information about the Lua functions that you can use for drawing, see Drawing Functions.
