The received line just appears to return a carriage return. When I turn on event viewing I can see an event on the output port but the port itself tells me that none events have occurred. I've got it all being refreshed every frame etc. does anyone have an example?
Would it be possible to add phase and period controls to the gradient image generators to make repeating and animated patterns? For example, give a Make Linear Gradient Image 3 colours but then give it a small period to repeat the 3 colours over and over. Phase would then let you animate the gradient over time with options similar to the Change Wrap Mode node such as mirror, hold, repeat etc.
It would also be great to have interpolation method control between the colours in order to make hard steps.
