From Christophe Loustaunau, "For our application, we need to write tiff file in floats. I have change a little bit the readerWritterTiff :
It check the data type of the image ( img.getDataType() ) and if it's GL_FLOAT :It save the tiff with float values.
Otherwise it does the same thing as before."
