development files for the OpenEXR image library
OpenEXR is a high dynamic-range (HDR) image file format developed by Industrial Light & Magic for use in computer imaging applications. . OpenEXR's 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. . This package contains the header files required if you wish to compile/develop applications that use OpenEXR libraries.
