OpenEXR is a high dynamic-range (HDR) image file format developed by Industrial Light & Magic for use in computer imaging applications. OpenEXR is used by ILM on all motion pictures currently in production. The first movies to employ OpenEXR were Harry Potter and the Sorcerers Stone, Men in Black II, Gangs of New York, and Signs. Since then, OpenEXR has become ILM's main image file format. OpenEXR's features include: * Higher dynamic range and color precision than existing 8- and 10-bit image file formats. * Support for 16-bit floating-point, 32-bit floating-point, and 32-bit integer pixels. The 16-bit floating-point format, called "half", is compatible with the half data type in NVIDIA's Cg graphics language and is supported natively on their new GeForce FX and Quadro FX 3D graphics solutions. * Multiple lossless image compression algorithms. Some of the included codecs can achieve 2:1 lossless compression ratios on images with film grain. * Extensibility. New compression codecs and image types can easily be added by extending the C++ classes included in the OpenEXR software distribution. New image attributes (strings, vectors, integers, etc.) can be added to OpenEXR image headers without affecting backward compatibility with existing OpenEXR applications. 2005-01-17 14:20:11 +01:00
Update to 1.6.1: 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. 2007-11-30 22:52:17 +01:00			`SHA1 (openexr-1.6.1.tar.gz) = b3650e6542f0e09daadb2d467425530bc8eec333`
