Write TIFF float images using CImg

I'm using CImg and I have noticed that I cant write TIFF images with float data. CImg wrotes them as 1byte/per pixel integer images.

¿Does anyone know if it is possible to write float images? Or, do you know other lib to do it.

CImg has probably one of the best tiff support of all image processing libraires out there, and is perfect to read/write float-valued multi-spectral images. But, you have to link your code with the libtiff library to allow it, by defining the macro 'cimg_use_tiff' as a compilation variable :

 #define cimg_use_tiff
 #include "CImg.h"

 ..

 CImg<float> img(..);
 img.save_tiff("file_float.tiff");
