[Openexr-devel] CTL not working with exrdisplay

[Brendan Bolles]

Hey all, has anyone gotten CTL working with exrdisplay?  I'm working  
in OS X (Xcode) and have gotten it all compiled and running with CTL  
included and turned on.  Marching through the debugger, I can see  
that the .ctl file is being found and it looks like transforms are  
being applied.  But the view on screen never looks any different -  
nearly the same as when you use no CTL at all (with the -T flag).   
I've been testing with the two included files that seem to work,  
transform_RRT.ctl and transform_EXR_DPX.ctl, but nothing happens with  
either of them.

It gets pretty confusing down deep in all that C++.  Is there  
anything I can look for that would verify that nothing is actually  
happening and try to maybe figure out why?

I'm using all the latest stuff.  Everything appears normal  
otherwise.  Here's what I've got in my shell:


[fnord:mac/build/Release] mrb% ./exrdisplay -C transform_RRT ~/ 
Development/sample_images/openexr-images-1.5.0/Tiles/GoldenGate.exr
