OpenEXR
OpenEXR is a high dynamic-range (HDR) image file format
developed by
Industrial Light & Magic for use in computer imaging
applications. The format has 16-bit floating-point color
component values, supports 32-bit unsigned integer and
32-bit floating-point data types, and several lossless compression
methods.
It provides the following tools:
- exrheader, a utility for dumping header information
- exrstdattr, a utility for modifying OpenEXR standard
attributes
- exrmaketiled, for generating tiled and rip/mipmapped images
- exrenvmap, for creating OpenEXR environment maps
- exrmakepreview, for creating preview images for OpenEXR
files
- exrdisplay, a sample application for viewing OpenEXR images
on a display at various exposure settings
- IlmImf, a library that reads and writes OpenEXR images
- Half, a C++ class for manipulating half values as if they
were a built-in C++ data type
- Imath, a math library with support for matrices, 2d- and
3d-transformations, solvers for linear/quadratic/cubic equations, and
more

Features include:
- Higher dynamic range and colour precision than existing 8-
and 10-bit image file formats
- Support for the "half" 16-bit floating-point pixel format
- 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
