- libopenexr-dev: 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.
