Install ilmbase and openexr to default location /usr/local Compile from within MATLAB: mex exrread.cpp -lIlmImf -I/usr/local/include/OpenEXR -L/usr/local/lib mex exrwrite.cpp -lIlmImf -I/usr/local/include/OpenEXR -L/usr/local/lib mex exrinfo.cpp -lIlmImf -I/usr/local/include/OpenEXR -L/usr/local/lib If OpenEXR is installed in another location (such as /sw), try these commands: mex exrread.cpp -lIlmImf -lIex -lImath -lHalf -I/sw/include/OpenEXR -L/sw/lib mex exrwrite.cpp -lIlmImf -lIex -lImath -lHalf -I/sw/include/OpenEXR -L/sw/lib mex exrinfo.cpp -lIlmImf -lIex -lImath -lHalf -I/sw/include/OpenEXR -L/sw/lib -- Usage -- Read image >> im = exrread(filename); Read image and alpha channel >> [im,mask] = exrread(filename); Image can be 1 or 3 channels of floating-point data Mask will be 1.0 if there is no alpha channel in the file Write image >> exrwrite(im,filename) Write image with mask in alpha channel >> exrwrite(im,mask,filename) Image can be 1 or 3 channels Mask must be 1 channel the same size as the image -- Details -- Does not support EXR images with uint16 data or float data All data is returned as MATLAB type double Negative, NaN, or Inf values in Y are set to 0 by exrwrite Negative, NaN, or Inf in RGB or alpha are preserved by exrwrite
