[Openexr-devel] Unit scale for Z values

Hi all,

Is there any mechanism in place, or planned, or rejected(!), for adjusting (deep) Z values to match a unit scale? In environments where you interchange deep EXR2's between packages which are working in different unit scales (eg. Maya in decimeters and Houdini in meters) you would want to convert to the unit scale to the hosted application upon read. I'd imagine you'd do this be comparing it to a unit-scale stored in metadata.

Regards,
Jason
