Font sizes for labels
by Jenny Black 27 Oct '04

27 Oct '04

Thanks for helping with all my other questions, heres another one... I would like to use two different font sizes for labeling passages, ideally in the same font-type. Is it possible to do this in therion? I have tried a few things... I have been using the "label" point symbol for these labels. The thbook suggests that the size of point symbols can be altered with "-scale s" however this doesn't seem to do anything to labels, so presumably it only works for certain point symbols? I tried using the line symbol for labels, but I would like to make the labels horizontal, and even if the line appears horizontal in the Map Editor, it doesnt end up horizontal in the final map (presumably it gets morphed with the passage?). I then tried to use the "remark" point symbol, and this successfully produces a small font size, however, whislt I figured out how to stop it being italic (-text "<rm>Passage Name") it seems to be in a different font type to the other labels produced by the "label" point symbol. Any ideas please? Thanks! Jenny

therion workshop
by Martin Sluka 26 Oct '04

26 Oct '04

Hi, we are preparing the Therion workshop. Date: last weekend of November - 27th and 28t'h. Place: Czech Republic - Moravian Karst - near Brno or Czech Karst - near Prague. Program: Main goal is - each participant should be able to create individualy cave map and other outputs in Therion. For participants: please bring your own computer if possible. To work with therion without one is not very practical. Cave program - it depends on interest. For details contact me, Stacho or Lada Blazek - blazek (att) speleo (ddott) cz Best regards Martin Sluka --

Therion 0.3.4
by Martin Budaj 22 Oct '04

22 Oct '04

Hello everybody, Therion 0.3.4 is available for download. The most important improvements are: - Error messages in Compiler window in XTherion are hyperlinked to data source files - group/endgroup inside centreline command - Windows installation: TeX/MetaPost works even if there is other TeX installation present in the system (it used not to run if there was TeXLive installed) Therion team

Unhelpful metapost error

My, I'm all questions today... When I try to process my survey to produce a PDF plan, metapost appears to not like something, but there's no error message, so I've no idea where to look. I've attached the log, I can send other stuff if that's helpful. This is therion 0.3.3 on Linux, with THUSESVX defined.

scale / base-scale question
by Jenny Black 13 Oct '04

13 Oct '04

Hi, >> How do I make underlying passage look paler than the main passage? > > > It is very simple: Adding in the "break"s within the maps worked well, thank you! Now I have another question to do with scaling... I want to print out the final survey at 1:500 (to be consistent with other caves in the area). However most of the cave passages are between 1 and 2m wide. I have noticed that you use 1:200 for drawing up passages of a similar width, and have therefore the symbol sizes have been designed accordingly. I tried several different combinations of scale and base-scale options, with the following results: 1) scale 1 500 * symbols (water and air flow arrows especially) are disproportionately large for the passage, the arrow heads of the water-flows are often larger than the passages they are in * wall lines seem very thick, and overshadow the smaller passages 2) scale 1 500 base-scale 1 200 * labels are small (but I can change that easily enough with the "fonts_setup" thing described in The Therionbook) * water-flow arrowheads are all wiggly rather than triangular * air-flow arrows and other symbols are great 3) scale 1 200 * symbols look good * but at 1:200, not 1:500, perhaps I could scale it in a graphics package before printing, though this seems like cheating! Any suggestions for how to create the best output? Thanks, Jenny

2 Therion Questions
by Jenny Black 11 Oct '04

11 Oct '04

Hi, I have just started using Therion to draw up some cave found this summer. And I have a couple of things that I wondered if it would be possible to change. I apologise if they are things that I will get used to as I become more familiar with using Therion. When you draw lines there is the little yellow tick mark at the first line-point telling you which side is inside the wall, or down the pit, or whatever. Would it be possible to make the tick mark larger (maybe twice the size?), so it was easier to see? I managed to draw up quite a lot before realising it was there! Also, when you "insert scrap" in the map editor, it places the "scrap" "end scrap" lines wherever you currently are, which will probably be in the middle of the previous scrap you worked on. I don't know if it would be possible for it to check whether this was in the middle of scrap, and if so, automatically insert the new scrap after the current scrap, or above the "end of file" line? Thanks, Jenny

Fixed station symbols
by zillig＠hoki.ibp.fhg.de 04 Oct '04

04 Oct '04

Hi, I´m new to therion and cannot solve this problem: when I try to mark station points as fixed (mark fixed) no special symbols are shown in the map or in legend (still there is the symbol for "temporary station"). Can anyone mail me an example file how it should work? Thanks Wolfgang Zillig

Ah- My build of therion is missing that menu item, which would explain why I was confused. Looks like the Debian build of therion does not have this facility, no doubt due to missing libraries etc. I hadn't realised the model viewer was internal to xtherion. I'll fix that soon. The Therion demo went reasonably well, although it's fair to say that at the moment Tunnel is easier to use. The comparison was very useful to people I think. I had a lot of trouble with therion 'path not connected' type messages when trying to create the demo. We need to work out some much more reliable way of getting error information to users. Currently if you do something wrong with area paths or joins that don't work you effective get an error of 'something is wrong somewhere' which is hopeless if you have just drawn a big chunk of cave. Even when there is a simple error, the error gives the line number; whilst the xtherion viewer shows 'item number' next to each entry - there is no way to relate these. As the whole thing is integrated it could easily show you the offending line - or even put you there in one of the windows.
