"\legendbox" "\loadpicture" and absolute paths
by rowena 14 Mar '21

14 Mar '21

Hello, I am using the "\loadpicture" capability in "\legendbox" constructs to include map sections, elevations, etc. It all works nicely on my PC where I am using relative paths to the pdf files. My club has a desire to archive the map data for posterity - ie if my pc dies or I go walkabout, the map data should still be available so that others can add to the maps as they are extended. I would prefer to have the images included using relative pathnames, rather than absolute pathnames, so that future explorers can download the map data and extend it, without having to duplicate my file hierarchy. How can I include relative paths in the \loadpicture functionality? Thanks, Rowena

Scale dependant error when using area fills
by Tom Foord 20 Jan '19

20 Jan '19

Hi all I'm having some problems compiling a project which includes debris area fills. Depending on the exact symbol fill that I use, I am getting strange scale-dependant errors which seem to cause the compiler to loop endlessly until I force it to stop. I originally noticed the problem when using a custom area fill that I made by modifying the standard a_debris_AUT symbol fill. I've attached my modified metapost definition in the attached text file 'a_debris_WUG.txt'. The error occurs for any scale between 1:2000 and 1:4483 (outside of this range the project compiles fine). See attached output log 'Output log - a_debris_WUG.txt'. As you can see, the file seems to loop over and over again. Initially I thought this problem was specific to my custom fill, but then I noticed that I also get a similar error when using the standard a_debris_AUT fill, however this time the error only occurs when the scale is set to exactly 1:2000 (any other scale seems to be fine). See attached output log 'Output log - a_debris_AUT.txt'. Can anyone help with this problem? Thanks Tom

Hi, I slowly learning how to generate maps with therion, but can't figure out how to display the survey shots in the map editor. I am using distoX2 with topodroid during surveys and then exporting the data to therion. Any help would be appreciated. Best regards, Þórir Már

DXF output
by Ben Cooper 03 Nov '17

03 Nov '17

I'm struggling to output a DXF format map and model from Therion. I've found that the map export does not load into two different DXF viewers, both giving no errors but showing nothing. The model output works, but is 100-times too small (ie the default unit appears to be cm rather than m). Can anyone provide any advice what I might be doing wrong? Many thanks, Ben

Therion 5.4.1 Windows Installer incomplete installs
by Bruce Mutton 24 Oct '17

24 Oct '17

Just a reminder, As far as I know, the current installation files mess up your Windows registry and both the installation folders if you have an existing installation in the ‘all users’ area and then you install over that with ‘only for me’. If you have a previous installation on a Windows machine, and you want to keep all your customised settings (ie without uninstalling the existing installation first), select 'Install for all users', and NOT 'Install only for me'. Otherwise you'll need to manually hack the registry to unpick the carnage. I posted about this on 30May2017, but for some reason it does not show up in the Mail Archive. I’ll post it again in parallel with this message. I’ll put my vote in again for the simple tried and true ‘install for all users’. Aside from the big issues (registry carnage), you know your installation files and settings will always be in C:\Program Files… Bruce From: Therion [mailto:therion-bounces@speleo.sk] On Behalf Of Michal Danko via Therion Sent: Monday, 16 October 2017 8:33 PM To: List for Therion users <therion(a)speleo.sk> Cc: Michal Danko <michal.danko(a)gmail.com> Subject: Re: [Therion] Therion] Therion 5.4.1 Windows Installer incomplete installs Hi all, any news about installer without admin rights?

I think it was that way in the old installer too. But there are also global Start menu shortcuts and registry entries that go into HKEY_LOCAL_MACHINE. For those the installer needs admin rights. If it doesn't have them, it comes down again to the All users vs Current user problem.

If this was done then users wanting to install without admin privileges could choose a location they have write permissions for.

I don’t think I would use a ‘non-installed’ version. The installer is compact, quick, easy and has proved versatile and reliable over at least 10 years.

Since I did the installer changes, here is that comes to mind: 1) I could try to make it more intelligent and to detect if there is an existing install location (all users or current user) and to install in the same one without the "All/Current user" prompt. This will probably not prevent all possible problems though. 2) Another solution would be to revert those changes and keep only the "All users" option, which requires admin privileges. This is how the older installers worked and always installed in Program Files. In addition to that, there could be a portable edition of Therion, which is distributed as a ZIP file and the user would only need to extract it in a folder. There would be no association to the TH, TH2 and THCONFIG file extensions of course. Currently the code reads the install location from the Win registry, but it could be made to search for files in the current folder. Does anyone have an opinion on what would be most useful? Would you use the portable option, or the "Current user" installer? Vladimir

<symbol-set>s missing from in the Therion Book
by Felix Ossig-Bonanno 24 Oct '17

24 Oct '17

I have just started learning Therion, and after drawing up my first survey I got some feedback. The main point was to use local symbols. So I set about trying to convert my survey to use the NSS standard. Reading the Therion Book <https://therion.speleo.sk/downloads/thbook.pdf> it seemed like it wasn't supported, as it is not mentioned on page 51 (along with some other standards that are actually supported). Searching some more I found that it was listed in https://therion.speleo.sk/wiki/_media/therion_symbols_20130407_.pdf along with several other <symbol-set>s not mentioned in the Therion Book. I wasn't sure if if these should be added, and thought i'd send this to make ppl aware. Regards, Felix

Exporting 3d models
by Graham Mullan 21 Oct '17

21 Oct '17

Is there any plan to allow the export of lox models in pdf format, so that they can be manipulated in Adobe Acrobat Reader? This would allow 3d models to be viewed more widely, by users who otherwise have no need to download & install Therion. Graham graham.mullan(a)coly.org.uk

Full Date to PDF Map
by Felix Ossig-Bonanno 19 Oct '17

19 Oct '17

Hi, I am very new to Therion. I have spent the last 2 days learning it and have completed the Footleg tutorial (http://wscc.darkgem.com/footleg/therion/) and am currently in the process of drawing up a small extension I surveyed a few days ago. I wanted to add the full date to the survey (at the moment it only shows the year), but short of just using the "map-comment" command, I haven't been able to work out how to do this. I'm sure it must be pretty straight forward, so hopefully this is easy to answer. If anyone has a good place for me to continue learning (on from the Footleg tutorial) that would also be cool, as I can see my self wanting to change how the maps look in other ways in the future (maybe the north arrow for example, specifying what kind of north it is representing). Thanks, Felix
