ABOUT THE OPENEXR_VIEWERS LIBRARIES ---------------------------- exrdisplay: exrdisplay is a simple still image viewer that optionally applies color transforms to OpenEXR images, using ctl as explained in this document: doc/OpenEXRViewers.pdf exrdisplay requires FLTK 1.1 or greater and OpenGL. playexr: playexr is a program that plays back OpenEXR image sequences, optionally with CTL support, applying rendering and display transforms in line with the current discussions at the AMPAS Image Interchange Framework committee (September 2006). The playexr directory contains the source code for the playback program, and two sample CTL transforms (one rendering and one display transform). playexr requires OpenGL, GLUT and the Cg hardware shading language. If you have installed the OpenEXR_CTL package, exrdisplay and playexr will automatically be built with CTL support. If you don't have OpenEXR_CTL, the programs will still work, but CTL support will be disabled. If you have questions about using the OpenEXR_Viewers package, you may want to join our developer mailing list. See http://www.openexr.com for details. LICENSE ------- The OpenEXR_Viewers source code distribution is free software. See the file named COPYING (included in this distribution) for details. BUILDING OPENEXR_VIEWERS ---------------- Building OpenEXR_Viewers requires the OpenEXR library. CTL support in OpenEXR_Viewers requires the OpenEXR_CTL library. If you want to build the 'exrdisplay' image viewer, you'll need FLTK 1.1 or higher. If you want to buyild the playexr image viewer, you'll need GLUT and the Cg hardware shading language. Your OS distribution may already include these libraries, or supply packages for them. That is the preferred way to obtain them for use with OpenEXR. If not, you can obtain the source code for FLTK from: http://www.fltk.org and you can download the NVIDIA Cg SDK from http://developer.nvidia.com. If you're building OpenEXR_VIEWERS on a Windows platform, see README.win32 for instructions. The remainder of this file applies only to GNU/Linux or other UNIX-like systems. After installing the required libraries, to build OpenEXR_Viewers on GNU/Linux or other UNIX-like systems, do this: ./configure make make install unless you obtained OpenEXR_Viewers directly from CVS, in which case you should first read README.CVS. If you have the Nvidia Cg SDK and you want to build support for fragment shaders into exrdisplay, specify the path to the SDK using the "--with-cg-prefix" flag. There are some additional compile-time configuration options available; type `./configure --help` for more information. 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.
