LibTiff Mailing List

I see the following in tiff.h:

#define     PHOTOMETRIC_LOGL		32844	/* CIE Log2(L) */
#define     PHOTOMETRIC_LOGLUV	32845	/* CIE Log2(L) (u',v') */

I also see that there are TestImages of these off the libtiff web site.

However, I can't find any definition of these in the TIFF 6.0 or TIFF 7.0
specs. What is the definition of the data and how would I convert to RGB?

Thanks,

Michael
