Yesterday someone on the list mentioned that samples can have complex values (with either integer or floating point real/imaginary parts), and I wracked my brains but absolutely could not figure out why you'd need that. Pigments are either there or not, in varying amounts; complex values don't make sense for that purpose.

Is this for non-image uses of the TIFF container format, or something?
