1.6.1 New versions of OpenEXR and CTL are now available. This release fixes a buffer overrun in OpenEXR and a Windows build problem in CTL, and it removes a few unnecessary files from the .tar.gz packages. 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. 1.5.0 * OpenEXR supports a new image compression method, called B44. It has a fixed compression rate of 2.28:1, or 4.57:1 if used in combination with luminance/chroma encoding. B44-compressed images can be uncompressed fast enough to support real-time playback of image sequences. * The new playexr program plays back moving image sequences. Playexr is multi-threaded and utilizes the threading capabilities of the IlmImf library that were introduced in OpenEXR 1.3.0. The program plays back B44-compressed images with fairly high-resolution in real time on commodity hardware. * The playexr program and a new version of the existing exrdisplay image viewer both support color rendering via color transforms written in the new Color Transformation Language or CTL. CTL is not part of OpenEXR; it will be released separately. CTL support in playexr and exrdisplay is optional; the programs can be built and will run without CTL. * In preparation for the release of CTL, OpenEXR has been split into three separate packages: o IlmBase 0.9.0 includes the Half, Iex, Imath and IlmThread libraries o OpenEXR 1.5.0 includes the IlmImf library, programming examples and utility programs such as exrheader or exrenvmap o OpenEXRViewers 0.9.0 includes the playexr and exrdisplay programs * The "Technical Introduction to OpenEXR" document now includes a recommendation for storing CIE XYZ pixel data in OpenEXR files. * A new "OpenEXR Image Viewing Software" document describes the playexr and exrdisplay programs. It briefly explains real-time playback and color rendering, and includes recommendations for testing if other image viewing software displays OpenEXR images correctly. * The OpenEXR sample image set now includes B44-compressed files and files with CIE XYZ pixel data.
