/*

Convert tif file into inr

To compile :

 g++ -o tiff2inr tiff2inr.cpp -O2 -L/usr/X11R6/lib -lm -lpthread -lX11 -fopenmp -l:libtiff.so.5

 Needs CImg.h

To execute :

 ./tiff2inr img.tif compress

 img : image in .tif

 compress : if 0 then output image is not compressed (img.inr), else the output is img.inr.gz
