Re: [Openexr-devel] Vector-of-float to vector-of-half conversion?
Yes, I have some SSE code that converts four floats in parallel. I can dig it out if anyone is interested... J.

[Openexr-devel] Determining version of OpenEXR library
Hi all, Sure this is somewhere, but having trouble finding it: how do I determine the OpenEXR library version that I'm building against? The particular situation here is that my code is built against various versions of OpenEXR, and wants to use some calls (e.g. isTiledOpenExrFile) that are only available in later versions. Thanks. -- James Bowman http://www.excamera.com/sphinx/articles-openexr.html ___ Openexr-devel mailing list Openexr-devel@nongnu.org http://lists.nongnu.org/mailman/listinfo/openexr-devel

Hi, I'd like to add your binding to openSUSE, but I did not find the license of it. OpenEXR is under the 3 clause BSD [1], so I expect that you'd like to use the same. Can you add the license to the upstream tarball (or on the homepage [2])?
