- : I want to know with libtiff the LAB encodage of the TIFF ie CIELAB, ICCLab ou JPEG Fax
It's D65 CIELAB.
- : I want to know the bits number per LAB channel by libtiff
- : I want to get the RAW LAB channels values of a pixel with libtiff
It's usually 8 or 16 bits unsigned, with L 0 - 100 and ab +/- 128 all scaled to 0 - 255 or 0 - 65535 in the obvious way.
