OpenEXR for Matlab

Note

This is a modified mirror repository for the OpenEXR-Bindings from HDRITools - High Dynamic Range Image Tools. The original code is either incompatible or hard to compile with the latest versions of OpenEXR and mex, so we modified and cleaned-up their code to be hassle-free compatible with the latest versions of MATLAB, Xcode and the OpenEXR-Library. The bindings were tested with OSx 10.9+, MATLAB 2014a 8.3.0+, Xcode 5+ and OpenEXR 2.0.0+.

The original code can be obtained at https://bitbucket.org/edgarv/hdritools/. The original copyright remains to Jinwei Gu and Edgar Velazquez-Armendariz.

What is it?

OpenEXR is a popular high dynamic range image fileformat mainly used by the film industry. This repository provides an interface for reading and writing OpenEXR files within MATLAB.

Install

First, make sure you have setup up mex. Otherwise run

mex -setup

inside of MATLAB.

Install the latest version of the OpenEXR-Library, e.g. via Homebrew

brew install openexr

Run make.m inside of MATLAB to compile the bindings. If you install OpenEXR without Homebrew make sure the paths inside of make.m point to your OpenEXR installation.

Ceveats

You may also need to update ~/.matlab/YOUR_MATLAB_VERSION/mexopts.sh (e.g. in case you get a xcodebuild error, saying a SDK can not be located). Just change all occurances of e.g. macosx10.8 to your version e.g. macosx10.10 (3 occurances, comments excluded). If you are still getting errors, make sure you have the correct version of XCode installed or install the SDK for your system (http://www.mathworks.com/matlabcentral/answers/243868-mex-can-t-find-compiler-after-xcode-7-update-r2015b)

Usage

exrread
>> image = exrread('my_image.exr');
>> size(image)
ans =

        1080        1920           3

>> max(image(:))
ans =

    2.9297

>> min(a(:))
ans =

    0.3069
exrwrite
>> a = 100 * rand(300,300,3);
>> size(a)
ans =

   300   300     3

>> exrwrite(a, 'a.exr');
