Projector actor: publishing Input and Output parameters separately

[eight]

I have a super wide movie frame, which I'd like to pan horizontally, to show just a portion of the frame at each point in time. I hoped to be able to do this by publishing an X offset of the input in the projector actor and then animating it using Envelope actor, however, it seems that this offset controls the projector's output, regardless of from where I am publishing it –– input or output control of the IzzyMap. Am I missing something, or this is a feature request?

Thanks.

 You could also use a Composite rectangle IzzyMap Slice and publish the x offset of each corner of the input separately, but then you have to do math to keep the image centered.

 I believe this is working in this configuration, unless I miss understand. 

My input is 3000px by 1080px In IzzyMap, 

I move my rect to the far left and select each right side corner, and enter 1920 (this creates my 1920x1080 output selection) 

I right click the Rect slice, and publish the Offset X 

Then on the Projector, I can move my view from the left edge to the right edge. (-1 thru 1)
