Elevation grid
by Vasily Vl. Suhachev 18 Nov '12

Hello Is there a way to make Therion not add one cell of grid at the top and bottom of the extended elevation map? After adding grid with export map -proj extended -layout-grid-size 250 250 250 m I have the following problems 1) large empty space at top and bottom of map 2) problems with old scale of map (Map is too large for PDF format. Try smaller scale!) -- WBR, Vasily

I took a look at Bruce's code, in particular Code to redefine area and point water symbols . This looks like something I'd like to use but how and where do I define the colour eg. if known colour_water_bg: thfill Path withcolor colour_water_bg; else: thfill Path withcolor white; fi; On 16 Nov 2012, at 11:00, therion-request(a)speleo.sk wrote: > Send Therion mailing list submissions to > therion(a)speleo.sk > > To subscribe or unsubscribe via the World Wide Web, visit > http://mailman.speleo.sk/mailman/listinfo/therion > or, via email, send a message with subject or body 'help' to > therion-request(a)speleo.sk > > You can reach the person managing the list at > therion-owner(a)speleo.sk > > When replying, please edit your Subject line so it is more specific > than "Re: Contents of Therion digest..." > > > Today's Topics: > > 1.

Metapost modifications
by Dave Clucas 16 Nov '12

16 Nov '12

In Mulu many of the passages are part filled with sandstone pebbles. I'd like to create a user area and a user symbol based on pebbles where the ellipses are filled with a colour (light brown). Can anybody tell me how to modify the standard definition? Dave Clucas dave(a)daveclucas.com http://daveclucas.com http://mycaves.org

loop misclosure error distribution
by Cepe 14 Nov '12

14 Nov '12

Hi! it is possibile to force Therion to compute one part of a loop and then to compute the remain part keeping the first computed part fixed or, in other words, to distribute the misclosure error only in the second part of the loop? Sorry for my very poor english.

area dimensions
by Bruce 13 Nov '12

13 Nov '12

I notice in the Therion source metapost there is an 'area dimensions'. It seems to be a clone of 'area bedrock', but perhaps there is a more cunning purpose? What is it for and how is it used? Bruce

Debug giving error
by Andrew Atkinson 13 Nov '12

13 Nov '12

5.3.9 on Debian wheezy I have obviously made a mistake when drawing up this elevation, as it is far to large. To try and get a clue I tried debug on It had compiled with debug off but gave an error with debug on (and all as well) **data.mp (mpost.mp (/usr/share/texlive/texmf-dist/metapost/base/plain.mp Preloading the plain mem file, version 1.004)) (./data.mp [4001] [4002] [4003] [4004] [4005] [4006] [4007] [4008] [4009] [4010] [4011] [4012] >> (nan-47.616,nan-3.48695,1,0,0,1) !

Te Reo Terione translation corrections to 5.3.10
by Bruce 13 Nov '12

13 Nov '12

Thanks for adding the Te Reo Maori translation, mi: to Therion Some minor corrections. Two of the entries should have lower case letters for mi: Line 585 & 600 of texts.txt should have a lower case 'p' Also should mention the existence of the Te Reo Maori, and have some credits in the Therion Book translations table for 'map header'. Translated by Kyle Davis, Bruce Mutton Cheers Bruce

Strange loch file
by Martin Sluka 12 Nov '12

12 Nov '12

I received totally fuzzy model .lox file. The reason was simple: two lines type wall were overlapped 1 segment of lines (first one first segment and second one last segment). My mistake, but to find it was quite detective work. m.s.

colour by map
by Andrew Atkinson 12 Nov '12

12 Nov '12

When you have coloured by map, in the header there Therion automatically added a legend of what colours go with each map. Generally I do not find this useful, but cannot find a way to turn it off, without doing a \def\maplayout in code, which seems over the top. Is it possible to turn off the map colour legend without resorting to code. It would be very useful to be able to stitch this off without having to redefine the header! Andrew

transparent colours in custom symbols not any more transparent than standard colours
by Bruce 10 Nov '12

10 Nov '12

Taking inspiration from Martins recent post on transparent colours I thought I might make my custom point water and area water transparent, or at least behave better with 'transparency on' than the standard non-transparent colours. Alas the code compiles without fuss, but the result is identical to the result when using standard (opaque) colour definitions. In my layout I have, in the order called. Define the area and point water def p_water (expr pos,theta,sc,al)= U:=(.425u,.3u); T:=identity aligned al rotated theta scaled sc shifted pos; pickup PenD; p:=fullcircle xscaled (1.2u) yscaled (0.8u) randomized (0.1u) rotated uniformdeviate (-45); %if known colour_water_bg: thfill p withcolor colour_water_bg; else: thfill p withcolor white; fi; if known tr_colour_water_bg: thfill p withtransparentcolor tr_colour_water_bg; else: thfill p withtransparentcolor tr_white; fi; thfill p withpattern pattern_water; %%% withcolor black; %but with failed attempt at black hatch thdraw p; %outline enddef; def a_water (expr Path) = T:=identity; % thclean Path; pickup PenD; % if known colour_water_bg: thfill Path withcolor colour_water_bg; else: thfill Path withcolor white; fi; if known tr_colour_water_bg: thfill Path withtransparentcolor tr_colour_water_bg; else: thfill Path withtransparentcolor tr_white; fi; thfill Path withpattern pattern_water; %%thdraw Path; %outline, not needed as area drawn is defined by line border anyway enddef; Optionally define the colours (the tr_white not needed as it is defined in the default distribution) !color colour_water_bg; %! forces interpretation as metapost colour_water_bg := (0.86,1,1); %light blue def_transparent_rgb(tr_colour_water_bg, 0.86, 1, 1); and then transparency on opacity 50 Everything in these examples is in a single scrap. I have checked that my code is being used by changing the colours, for example from tr_white to tr_black etc and these changes are reflected properly, it's just that they are not transparent. In Adobe Reader it looks like this (below) (the water on the right is definitely not transparent - the rock place bottom is obscured) Adobe also seems to make the colours and line weights different to the others - incorrectly I suspect. If I run this example with transparency off (but still using my custom transparent colours), the result is identical EXCEPT all the colours are much more intense. In Foxit Reader it looks like this (below) with transparency on (Foxit always makes everything transparent when transparency is on, so it is not really a test) So again, no difference whether using transparent colour definitions or non-transparent. When transparency is off, it looks exactly the same as in Adobe. In Evince it looks like this (after about 1 minute to load the modest file-Evince also behaves just like Foxit, but has a problem with hatches extending out into the bounding box as well) So as you can see the viewing software may be masking (a little) what Therion is really trying to do, however it seems to be somewhat like either almost everything is opaque, or almost everything is transparent, and the promise that transparent colours seem to offer some more control cannot be realised? What I would like is something closer to what Adobe is rendering (with the finer line work of Foxit) , but with the 'rock-border place bottom' showing through the water when the water is defined with a transparent colour. I guess when transparency is on, water and sump should always be transparent to underlying objects, but closed rock-borders and the rocks in 'area blocks' should never be. After all that maybe I need to be looking at the rock-border and area blocks definitions? Any ideas why transparent colours make no difference at all? Any ideas how to make the rocks in area blocks and closed rock-borders opaque to any objects (in the same scrap) beneath them without messing up the transparency of other objects? Bruce
