ACES (based on OpenEXR) uses unsignedLong. Was this an ACES special only? Lars

It would be nice to revisit the exif discussion as well.

A time stamp is just one that can't fit into 32 bits. The others probably fit into 32 bits for the near future, but it would be wise to allow for 64-bit integers just in case. Looking at how IntAttribute, DoubleAttribute, etc., are implemented, it seems like an easy addition, and I think it would be useful to others.

We need 64-bit integers for some quantities like timestamps, and commercial tools like Nuke or RV don't understand our private implementation of an attribute that contains a long int. -- Dick Hadsell 203-992-6320 Fax: 203-992-6001 Reply-to: [email protected]<mailto:[email protected]> Blue Sky Studios http://www.blueskystudios.com<http://www.blueskystudios.com/> 1 American Lane, Greenwich, CT 06831-2560 _______________________________________________ Openexr-devel mailing list [email protected]<mailto:[email protected]> https://lists.nongnu.org/mailman/listinfo/openexr-devel _______________________________________________ Openexr-devel mailing list [email protected]<mailto:[email protected]> https://lists.nongnu.org/mailman/listinfo/openexr-devel
