"\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

Therion 5.4.1 Windows Installer incomplete installs
by Bruce Mutton 16 Oct '17

16 Oct '17

Things are getting weirder. Usually I have just installed one version of Therion over top of whatever version I have installed, but wonder if this might be contributing to issues I have here. After I have installed 5.4.1 over top of 5.4.0. If I open a thconfig file, with Help About I get 5.4.1 reported, as below If I then open a .th2 drawing file, I get 5.4.0 reported, as below So with two instances of XTherion open at the same time, each is reporting a different version. Same thing happens installing 5.4.1 88c8a06 over top of 5.4.1. The drawing editor still reports 5.4.0 Perhaps a harmless bug/omission or something odd with the installer? Initial drawing suggests the drawing editor is behaving like 5.4.1 (triangular survey stations).

A while back I reported problems with beta versions of Therion related to 'loop-closure survex'. They were fixed in 5.4.0 Now using 5.4.1 those projects/thconfigs that crashed before now seem to be OK, but I have now found another project/thconfig that crashes with 5.4.1 but not with 5.4.0 5.4.1 runs OK with 'loop-closure therion' but gets killed by Windows 10 when I use 'loop-closure survex'. Am still using survex 1.2.27. I have attached the log file with 'loop-closure survex'. Not sure if it is related, but I notice that if I install 5.4.1 'Install Only for Me' it will not overwrite a previously installed 5.4.0, even though the installer does not report any errors or problems to the user. Ie it fails even though it looks like it has worked just fine. To get 5.4.1 to overwrite 5.4.0 I need to "Install for all users". Bruce

Therion] Therion 5.4.1 Windows Installer incomplete installs
by Bruce Mutton 16 Oct '17

16 Oct '17

Just following up on what I think is a serious problem with the 5.4.0 and 5.4.1 Windows Installers (as described below). I think the Windows installers should be taken offline until they can cleanly install in all likely situations. Either that all provide explicit information on the download page as to the limitations and how to fix the problems the installers are likely to cause.

I will stick to “all users” Therion installs from now on, as that puts the files in a location where I am used to looking for them. If the installer ever handles uninstalls, then the .ini files should be preserved.

The former requires admin privileges, and the later can be used by a limited user. Older installer versions used Program files by default, and the new files would always overwrite the older ones. But if you had an older version in Program Files, and installed the new one for the current user in his AppData folder, you would end up with two sets of files. And with conflicting file type associations. You could try uninstalling and manually deleting the Therion install folder. Cleaning the registry entries requires using Registry Editor and deleting a set of keys, if you are comfortable doing that. The keys are these (after the text "Subkey". HKLM is HKEY_LOCAL_MACHINE and HKCU is HKEY_CURRENT_USER) https://github.com/therion/therion-batteries/blob/master/therion.iss#L60-L1… I suppose a better solution would be if I can make the installer uninstall any previous version before installing. This should prevent such an issue. Vladimir On Mon, May 29, 2017 at 1:12 PM, Bruce Mutton via Therion <therion(a)speleo.sk <mailto:therion@speleo.sk> > wrote: Things are getting weirder.

Import a scrap into another scrap (or th2-file)
by torstein finnesand 11 Oct '17

11 Oct '17

Hi fellows, Sometimes I realize that two scraps should have been one (for instance scrap A in A.th2 should have been a part of scrap B in B.th2), in particular when it's difficult to join them. It's easy to insert the xvi file into the scrap B file. But I have to draw it again. Is there any workaround here? Torstein Finnesand Norway

Bug of symbol for point passage-height in legend?
by Torsten Schnitter 01 Aug '17

01 Aug '17

Hi I observed a strange behavior of "point passage-height" or better let's say of it's symbol size in legend. Using scale and base-scale in layout with different numbers the size of the symbol is changing in size and shouldn't. Other symbols like e.g. water flow don't behave like this. They don't change their size in legend when changing base-scale. For example: scale 1 500 base-scale 1 1500 The size of the symbol in legend is way to big and therefore doesn't fit into it's box anymore. Is there any solution for this problem? Thanks, Torsten

Missing fonts when compiling a map
by Bill Gee 25 Jul '17

25 Jul '17

Hello everyone - A week ago I upgraded to Fedora 26. Today is the first chance I have had to run Therion. When compiling a map, it produces two lines about missing fonts. See the messages below. The compile otherwise runs to completion and the map renders correctly in Okular. I have Googled on these font names, but nothing turns up. Where should I look to see if they are installed? Where do they come from? Should I be concerned about it?? Thanks! -- Bill Gee BOINC Statistics therion 5.4.1 (2017-04-18) initialization file: /etc/therion.ini reading ... done checking optional fonts csr10 csti10 csbx10 csss10 csssi10 ...

How to frame a box?
by Torsten Schnitter 19 Jul '17

19 Jul '17

Hi I'm wondering if it's possible to draw a frame around e.g. a legendbox or any other box? (I'm not talking about the frame around all the map which you can get with e.g. \framethickness=1mm) In layout I'm using code like this: \def\maplayout{ ... \legendbox{0}{0}{NE}{\legendsymbols} \legendbox{0}{0}{NE}{\the\legendcontent} ... } Is it possible in any way to draw a frame around such a box? Or does anyone have any code to get a framed box on the map? Thanks for your help. cheers, Torsten
