Thanks Hans. I know the example patch already and I have [pix_rtx] working fine inasfar as I can get it to do what the example patch already shows. I think my question is more about data flow and Gem. My patch and [pix_rtx} are just an example of a more basic misunderstanding I believe I have which has not been cleared up despite many hours of work in Gem.
Could somebody explain to me my [pix_rtx] in my example patch appears to be processed before the rotation instead of after? -John On Tue, Mar 24, 2009 at 9:33 PM, Hans-Christoph Steiner <h...@eds.org>wrote: > > I think this is an appropriate place to discuss gem.
