[Bf-committers] ASC-CDL test suite compliance

[Julien Enche]

Hi,

I've submitted a first version of the DPX/Cineon patch :
http://projects.blender.org/tracker/index.php?func=detail&aid=27397&group_id=9&atid=127
I hope it can be useful. Feel free to report any problems you could
encounter with it.

Julien

>>  * Screenshots of the tested setup.
>>  * Reference DPX's and the .ccc list from the ASC-CDL reference

>>  * Blender's output from the .blend files rendered as DPX

>> OpenImageIO was compiled from a recent trunk.
