[Therion] Development 5.4.1+4369eea inverts and recolours altitude legend

Thu Dec 14 20:37:08 CET 2017

Great, thanks for testing it. If it works, then no need for that sample.

Hi Stacho

Therion-setup-dev-e7e9d34 has fixed both problems.  I have double checked,
and if 4369eea is reinstalled the ‘out of order’ colours reappear.

Do you still want a sample for future reference?

Hi Bruce,

I have fixed the altitude coloring in latest commit, but I was not able to
reproduce your strange coloring of scraps. For me it seems to work fine.

Could you please send me some data sample for inspection of this bug?

Thanks, S.

FYI not only are the colours inverted, but they are a bit out of order as
well.

Refer the images.

I have not used any lookup syntax yet, partly as I am keeping my projects
compatible with earlier Therion versions.

These were generated with 5.4.1+ce29e7b

Hi Bruce,

thanks for pointing out this bug. I will check the order of numbers, I have
probably made some mistake when dealing with automatic color scale
generation.

I have rewritten the scale code completely, but I had no time until now to
write the docs. But if you want to try, something like that should now work
in the layout:

lookup altitude -title "Altitude legend"

700 [100 0 0] "700 m a.s.l."

680

660

640

620

600 [0 0 100] "below 600 m"

endlookup

It should generate red -> blue scale with desired values. Also explo-date,
topo-date should now work with addition to maps, scraps. E.g.

export map -layout-color map-fp topo-date

and for example:

lookup topo-date

2010.12.31 [] "2010 and before"

2011.12.31 [] 2011

2012.12.31 [] 2012

- [] "2013 and later"

endlookup

You may specify multiple lookup tables for same criterion using ":"
separator in label

lookup altitude:scale1

600

800

endlookup

and

lookup altitude:scale2

800

750

700

endlookup

and use then "color map-fg altitude:scale1" or "color map-fg
altitude:scale2"

You may use also:

lookup maps

map1 at some_survey [color]

map2 [color]

map3 [color]

endlookup

Same should work with scraps. With maps, also more simple way should work -
you may specify color of a particular map within selection.

select map1 -color [100 0 0]

Also intervals should work:

lookup altitude

[1500 1600] [] "cave floor 1"

[1800 1900] [] "cave floor 2"

endlookup

If you are willing to try, I would appreciate any feedback. Probably there
are a lot of bugs because a lot of use-cases. I was not able to test them
all.

I’ve just noticed that the latest development snapshot 5.4.1+4369eea seems
to have messed with the altitude legend.

You can see from the screenshot below, which shows part of identical
project compilations, one with 9d96803 and then one with 4369eea.

Pretty sure I have not made any other changes that could have caused this
at my end, and I see that some of the intervening commits on github relate
to colour changes.

Neutral (perhaps) changes are that there are more colour bands and the
colours are brighter, in the legend at least, though not in the map.

A negative change is that the altitude range is now upside down.
