They would, but the intention was that - rather than having to manually select all the colours to get the perfect graduation of colours (which you have to do if you use a lookup table), you could get Therion to automatically take the height from a map, since it already knows those heights, and knows exactly how to colour those parts. I had thought about using lookups, but it feels very clunky as an approach, since it means manually specifying the altitudes of the highest and lowest points - manual knowledge of automatically calculated data. With a lookup, you need to know exactly the colours it will have selected for each height that matters. Each time a new piece of passage gets added to the top or bottom of the cave, which then changes all of the automatic colouring within the cave, you will have to re-calculate the lookup colours again for use with your subset maps. With "altitude-relative caveMP@cave" this would all become automatic. _______________________________________________ Therion mailing list [email protected] https://mailman.speleo.sk/listinfo/therion
