./graphics/openexr, High dynamic-range (HDR) image file format library and tools

[ CVSweb ] [ Homepage ] [ RSS ] [ Required by ] [ Add to tracker ]

Branch: CURRENT, Version: 2.5.1, Package name: openexr-2.5.1, Maintainer: adam

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.

This release also fixes an improper failure in IlmImfTest when running on ARMv7 \ 
and AAarch64.

Minor release with miscellaneous bug fixes and small features

## Summary

* No more build-time header generation: toFloat.h, eLut.h,
  b44ExpLogTable.h, and dwaLookups.h are now ordinary header files, no
  longer generated on the fly.
* New StdISSTream class, an "input" stringstream version of StdOSStream
* New Matrix22 class in Imath
* Chromaticity comparison operator now includes white (formerly ignored)
* Various cmake fixes
* Bug fixes for various memory leaks
* Bug fixes for various invalid memory accesses
* New checks to detect damaged input files
* OpenEXR_Viewers has been deprecated, removed from the top-level
  cmake build and documentation.
