[Openexr-devel] 2.2.0 release plans

[Ed Hanway]

Hi openexr-devel,

 

We've pushed some new commits to the develop branch in preparation for a release at the beginning of August.   The significant new functionality includes:

 

-          A new high performance lossy compression codec contributed by DreamWorks Animation.  This work includes performance improvements to the Huffman decoder that also speed up the PIZ codec.

-          A new IlmImfUtil library intended to make it easier to develop simple utilities for image file manipulation, supporting the myriad of types of OpenEXR structures (deep, subsampled channels, multi-resolution, tiled, arbitrary channels, and so on).

 

Existing APIs are unchanged.

 

Also, while autoconf is still the method of choice to build OpenEXR on *nix platforms, the support for CMake should be up to date at this point and working for Linux, Xcode and Visual Studio.

 

Unless we run into any roadblocks, my plan is to merge to master and cut a 2.2.0 release by SIGGRAPH.  The platforms we've tested in ILM are gcc 4.4, gcc 4.6, OSX Mavericks / Xcode 5.1, and Visual Studio 2010.  We'd appreciate if anyone has the time to verify on other platforms and/or spot any regressions in the next few weeks.

 

-Ed
