I think this add-on might be what you need: TROIKATRONIX : ISADORA - DX – Rotate Canvas

It uses Matte to create a new canvas at the required 'rotated' dimensions, and then drops the image into this new canvas.

Could you DM me the User Actor and/or patch so I can take a look?

Hi all,

I would like to use TouchOSC (new version) to run a show from a couple of iPads. 
In my ideal world the interface that I'm building would show the Q number, the name of the current scene, and the Q number and name of the next scene.

Just wondering if anyone has already built something like this, to save me reinventing the wheel :-)

Thanks

Mark (no...)
