Write TIFF float images using CImg

Question

Hi! 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.

Answer 1

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 img(..);

img.save_tiff("file_float.tiff");
