ABOUT THE OPENEXR LIBRARIES
|
|
----------------------------
|
|
|
|
IlmImf is our "EXR" file format for storing 16-bit FP images. Libraries in
|
|
this package depend on the IlmBase library.
|
|
|
|
See the IlmImfExamples directory for some code that demonstrates how
|
|
to use the IlmImf library to read and write OpenEXR files. The doc
|
|
directory contains some high-level documentation and history about the
|
|
OpenEXR format.
|
|
|
|
If you have questions about using the OpenEXR libraries, you may want
|
|
to join our developer mailing list. See http://www.openexr.com for
|
|
details.

|
LICENSE
|
|
-------
|
|
|
|
The OpenEXR source code distribution is free software. See the file
|
|
named COPYING (included in this distribution) for details.
|
|

|
|
BUILDING OPENEXR
|
|
----------------
|
|
|
|
Building OpenEXR requires the IlmBase and the zlib library.
|
|
|
|
You can obtain the source code for zlib from:
|
|
|
|
http://www.zlib.net
|
|
|
|
If you're building OpenEXR on a Windows platform, see README.win32 for
|
|
instructions on how to build OpenEXR. The remainder of this file
|
|
applies only to GNU/Linux or other UNIX-like systems.
|
|
|
|
After installing the required libraries, to build OpenEXR 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 OpenEXR in MacOS X.
|
|
|
|
Do `make check` to run the OpenEXR 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 OpenEXR to a particular
|
|
platform.
|
|
|
|
All include files needed to use the OpenEXR libraries are installed in the
|
|
OpenEXR subdirectory of the install prefix, e.g. /usr/local/include/OpenEXR.
|
|
|
|
|
|
USING OPENEXR IN YOUR APPLICATIONS
|
|
----------------------------------
|
|
|
|
On systems with support for pkg-config, use `pkg-config --cflags
|
|
OpenEXR` for the C++ flags required to compile against OpenEXR
|
|
headers; and `pkg-config --libs OpenEXR` for the linker flags required
|
|
to link against OpenEXR libraries.
