ABOUT THE ILMBASE LIBRARIES 

----------------------------

Half is a class that encapsulates our 16-bit floating-point format.

IlmThread is a thread abstraction library for use with OpenEXR

and other software packages.  It currently supports pthreads and

Windows threads.

Imath implements 2D and 3D vectors, 3x3 and 4x4 matrices, quaternions

and other useful 2D and 3D math functions.

Iex is an exception-handling library.

If you have questions about using the IlmBase libraries, you may want

to join our developer mailing list.  See http://www.openexr.com for

details.

LICENSE

-------

The IlmBase source code distribution is free software.  See the file

named COPYING (included in this distribution) for details.

BUILDING ILMBASE

----------------

To build IlmBase on GNU/Linux or other UNIX-like systems, do this:

./configure

make

make install

unless you obtained IlmBase directly from git, in which case you

should first read README.git

Please type :

./configure --help

for a list of options in relation to building IlmBase libraries. In 

particular, peruse README.namespaces for information regarding the 

use of namespaces in IlmBase and OpenEXR.

See README.OSX for details on building IlmBase in MacOS X.

Do `make check` to run the IlmBase confidence tests.  They should all

pass; if you find a test that does not pass on your system, please let

us know.

Other UNIX variants haven't been tested, but should be easy to build.

Let us know if you're having problems porting IlmBase to a particular

platform.

All include files needed to use the IlmBase libraries are installed in the 

OpenEXR subdirectory of the install prefix, e.g. /usr/local/include/OpenEXR.

USING ILMBASE IN YOUR APPLICATIONS

----------------------------------

On systems with support for pkg-config, use `pkg-config --cflags

IlmBase` for the C++ flags required to compile against IlmBase

headers; and `pkg-config --libs IlmBase` for the linker flags required

to link against IlmBase libraries.
