A stream declaration allows one to stream image data to a Shadron extension. The stream will commence after clicking the stream icon, which will appear in place of the export icon whenever a stream is available. It must be pressed again in order to stop streaming. If both exports and streams are present in the same script, you can toggle between the two by right-clicking the icon.

The syntax is:

stream <initializer>;

The names and arguments of stream initializers are dependent on individual extensions.
