I discivered the colouring features because Jenny Black used them, and they hare in one of the example files. Very nice indeed. But of course I am not satisfied with what I am given :-) Colour scrap by altitude is nice but the abrubt joins can look nasty in the middle of wide, nominally horizontal passage. It works really well in the 'soundriver' area where there are nicely-merging shades of green, but nastily in other some other areas. Some way to graduate the join a bit would make it look a lot nicer. Or apply more detailed colour control to a scrap like 'nearly the same as neighbour scrapname'. Also my users have complained that the colours are 'too random and garish' and I am inclined to agree. They like the depth colouring in Aven, so could we try to use the same gradient colours? Probably what is really needed is a way to specify the colour set/gradient, and proably a way to specify it for individula scraps too. Perhaps I already can? In colour by map there should be some way to allocate colours to maps. This is particularly necessary where you have sloping levels - you would want to make one level one colour but the altitude will vary a lot. Making one level into one map should fix this, but I would want to be able to set the colours for a level. At the moment if you add a new map suddenly the colours will all change round - this would be a problem when doing an update for next year, when users might expect caves (maps) to retain old colours. I think the colouring is a major step forward, but some more detailed control is needed. There are a lot of ways this could be done and input for others is welcome. Also having blue water would make a lot of sense for water areas, streamflow arrows etc. Wookey -- Aleph One Ltd, Bottisham, CAMBRIDGE, CB5 9BA, UK Tel +44 (0) 1223 811679 work: http://www.aleph1.co.uk/ play: http://www.chaos.org.uk/~wookey/

This I have to discuss with MartinB. As far as I know PDF - some gradient colorings are possible, but only for triangles. Not for bezier curves. So in principle, there are two possibilities: 1. Triangulate the outline = huge problem of contrained Delaunay triangulation. All algorithms I have are GNU incompatible, or parts of huge non-standard libraries or both :). In any case - triangulation is also important for 3D (current algorith fails at some cases, especially on non Intel processors :) so this problem must be solved somehow in the future. We will probably leave GPL and come to some other license type (I prefer no licensing at all :)

No, it is in TODO only. When I will fix the bugs, I can start working on it. It should be no problem. User must be able to define own colors for altitudes, maps, surveys, dates and use multiple color gradients (aven like for example). It is in TODO, but nobody was asking for this and my main problem is 3D.

Yes. 100% agree. I will put it higher priority.

This you can do by redefinition of symbols. See "Rabbit-cave" example - extended elevation. There the water should be blue. Simmilar way you can redefine colors of other symbols in layout. S.
