August 3, 2007 - New stable versions of OpenEXR and CTL are now available.
The source code has been tested on Linux, Mac OS X and Windows (Visual Studio
7 and 8). Here's a summary of the changes since the last release:
OpenEXR 1.6.0
- Reduced generational loss in B44- and B44A-compressed images.
- Added B44A compression. This is a variation of B44, but with
a better compression ratio for images with large uniform areas,
such as in an alpha channel.
- Bug fixes.
CTL 1.4.0
- Added new functions to the CTL standard library: 3x3 matrix
support, 1D lookup tables with cubic interpolation.
- Added new ctlversion statement to the language.
- Bug fixes.
OpenEXR_CTL 1.0.0
- Applying CTL transforms to a frame buffer is multi-threaded.
- Bug fixes.
OpenEXR_Viewers 1.0.0
- Implemented new naming conventions for CTL parameters.
IlmBase 1.0.0
- Half now implements "round to nearest even" mode.
