Problem compiling Therion 6.1.7 on Fedora 38
by Bill Gee 24 Jul '23

24 Jul '23

I gave it a shot today to see if I could duplicate Rodrigo's problem. I got a completely different error: =========================== [bgee@main2 build]$ cmake .. CMake Error at cmake/Dependencies.cmake:8 (find_package): By not providing "Findfmt.cmake" in CMAKE_MODULE_PATH this project has asked CMake to find a package configuration file provided by "fmt", but CMake did not find one. Could not find a package configuration file provided by "fmt" with any of the following names: fmtConfig.cmake fmt-config.cmake Add the installation prefix of "fmt" to CMAKE_PREFIX_PATH or set "fmt_DIR" to a directory containing one of the above files. If "fmt" provides a separate development package or SDK, be sure it has been installed. Call Stack (most recent call first): CMakeLists.txt:18 (include) =============================== This is Fedora 38. The compile of 6.1.6 on Fedora 37 worked correctly for me. 6.1.6 still works after the upgrade to Fedora 38. I did not recompile it. -- =============== Bill Gee

map colour usage description in Therion Book
by Bruce Mutton 10 Jul '23

10 Jul '23

Hello Just now I was having difficulty remembering how to colour a particular map a specific colour, different to the colour scheme applied to most of the maps being output. My first challenge was to figure out that this could only be done via 'select' in a thconfig, and not within the definition of a map. I think that the Therion Book could do with a small edit to clarify usage of 'select map -colour [r g b]'. The Therion book says. 'map' Description: A map is a collection of . Arguments: . . colo[u]r <color> set the map colour; this option overrides the automatic choice when the layout specifies colour map-fg [map]. >From that I had the incorrect impression that specifying a colour when selecting a map for output would always override. What I have found is that this is only sometimes true. Map select colour overrides when. colour map-fg [r g b] colour map-fg scrap colour map-fg map Map select colour does not override when. colour map-fg altitude colour map-fg topo-date colour map-fg explo-date For (sub)maps where there is no date set, the map select colour will be shown, otherwise select map -colour [r g b] has no effect. So I suggest an edit to the Therion Book along the lines of. 'map' Description: A map is a collection of . Arguments: . . colo[u]r <color> set the map colour when selecting a map; this option overrides the specified colour palette when the layout specifies colour map-fg [map], [scrap] or [<colour>]. It has no effect when the layout specifies colour map-fg [altitude]. It has no effect when the layout specifies colour map-fg [topo-date] or [explo-date], for the scraps whose associated surveys have dates assigned. I have not assessed how this plays out with lookups <https://therion.speleo.sk/wiki/examples#colour_palette_scales_-_lookups> , but I imagine they should not have any different impacts to those described above.

Creating GeoTIFF files
by Bill Gee 07 Jul '23

07 Jul '23

A question has come up from one of my caver friends who is very new to cave survey but an old hand at ArcGIS and various other ESRI tools. He earns a living as a GIS expert. He would like to get a georeferenced TIFF (GeoTIFF) which includes GPS coordinates of survey stations. I looked at the KML file produced by Therion and find no references to survey stations. A KML file is really just a long (very long!) list of GPS coordinates, so it probably could include survey stations. So my question for the group: Is there a way to produce a GeoTIFF file which includes survey stations? Related question: Do the ESRI outputs from Therion include survey stations? Thanks! -- =============== Bill Gee

Hi folks, Is there any way to create a multi-line map-comment? An example assuming "\n" does what I want: map-comment "Line one.\nLine two." Would create: Line one. Line two. Thanks! Erik

Transparency and connection issue
by david Le berre 23 Mar '23

23 Mar '23

Dear All New comer on this forum and new user of Therion for 18 months, I'm currently stucked by 2 issues that are certainly obvious for most of you but after lots of trials I dare to ask you!!! 1- Transparency on colour filled areas: Since I have colored some areas and customized some colors as well, I have lost transparency on overlapping cavities. Despite many trials in the layouts no success.I use in my layout for exemple: #clay-orange def a_clay (expr p) = T:=identity; thfill p withcolor (0.96, 0.82, 0.55); enddef; Result it looks better but it is far more difficult to understand some overlapping areas, see hereunder. I guess if I define a special pattern including 50% of colour and 50% of non-colored pixel it could work but I'm not skilled enough to play with metapost.Any ideas to have the transparency back? 2. Connexions lines for offseted scraps:My project covers a 4 kms cave that I have splitted into 4 sub-projects (called networks), I work in each network and gather them to get final export, usually I use connexion point in the scrap. - Network 1 is above Network 2, therefore in the final presentation I offset Network 2 - Network 2 includes itself offseted areas which appear well when I work on export of Network 2 only. When I compile the global project all connexion's doted lines inside network 2 appears then linked to the shadow of the network 2 offseted from the Network 1 instead of staying linked to the Network 2 representation, result is hawfull with dotted lines crossing every where and ending in the shadow area.Any ideas to maintain local connexion dotted line where they were at the beginning? Thanks in advance David
