Hum - I suspect something is amiss here: if it's 8-bit, it's unlikely to be
RGB (unless it's a dismal 3:3:2 range). Besides, temperature is a single
dimension, so monochrome would make sense - or is it that you're getting an
indexed colour image which is mapping greyscale values to a coloured
palette? If you're lucky, the range of temperatures directly corresponds to
colour index, which would allow you to simply ignore the palette itself and
use index values directly.

I suspect you're far better off working with this data in a raw binary
format, especially to store it in Valentina. I'd suggest building a binary
object and storing it in a blob. In RB this could just be an array, but in
Director you might be able to use imaging lingo.
