labelling grids
by Bruce Mutton 22 Apr '08

22 Apr '08

Further to the posting below, I'm just wondering if there are any updates on the ability to label co-ordinate grids with the northings and eastings at the edge of each sheet (map and or atlas). (I have modified the grids to be displayed as continuous lines.)

Unfortunately, not yet. It's somewhere in to-do list. . Martin

User Interface TO DO List Request
by Bruce Mutton 22 Apr '08

22 Apr '08

A few items for consideration for the user interface. COMPILER WINDOW 1. Add 'search & replace', similar to the other windows. (Disrupts work flow to open config files in the text editor each time.) 2. Allow the split pane bar to move up and down the window. The editing area is usually too small. As a compromise, having an upper, middle and lower position would be a great help. ALL THREE WINDOWS 3. Add two buttons (or menu or key combinations), -one to comment out the selected block of text (add # to the start of each line), and -one to uncomment the selected block of text (remove the first non-space or non-tab character from the start of each line, provided it is a #) 4. In the case of the MAP EDITOR the actions would be. -Comment out the selected object, and -Uncomment the selected object This would allow temporary hiding of an object without having to delete it and completely redraw it (or find it's code in the data file and copy it elsewhere for safe keeping) Comments?

cave-list?
by Bruce Mutton 22 Apr '08

22 Apr '08

I noticed an export item 'cave-list', however I get empty output files. I can not find much explanation of this (new?) feature. I have three caves with survey data entered, and a number of scraps, and one cave entered as a scan of a plan view of an old cave map (no survey data, but two dummy stations with co-ordinates entered) Two of the surveyed caves are connected by survey centrelines, and one is not (but will be when finished entering data) One of the stations for each cave contains a line similar to; station N2 "Greenlink Entrance" attr entrance and my thconfig file both for an individual cave, and for the system of all four caves, contains something like; export cave-list -output ../Outputs/Greenlinkcaves.txt\ -location on Alas I always get empty outputs. What data should be entered to obtain output? What information is output? Thanks Bruce PS I like the new look Therion Book, new behaviour of layout-comment, how Therion now tidies up it's temporary files and the warning highlight in the Compiler with the new 2008.04.16 snapshot. Good work!

Surface image obscures cave plan image
by Bruce Mutton 22 Apr '08

22 Apr '08

I've tried to export a pdf with a scanned cave plan image overlying a scanned surface image. I can get one or the other but not both. I can get surveyed and 'scrapped' drawings to overlie scanned surface images. I have used the following statement in my layouts; surface-opacity 10 # tried values from 10 to 70 surface bottom #top/bottom/off What I have found is that the opacity affects both the surface image and the cave plan image, with the effect that the surface always obliterates cave image. I can live with this, but am interested if there is a work around. Bruce

Surface woes
by Bruce Mutton 18 Apr '08

18 Apr '08

Have just had some partial success at adding a surface to my outputs. I have cave data, georeferenced to the same co-ordinate system as that below, that covers at present 1km x 1km in plan, but I expect to add other systems to extend this area. I have cropped a jpg topo map image to an area 3km x 3km I am exporting at 1:1000 to pdf (900mmx1012mm) I have labelled grids at 100m centres on the cave map, so I know from observing the output that the grids and the cave are correctly georeferenced. Trouble is the jpg seems to be "zoomed in" many times too much. My *.th data as follows; survey. surface #Canaan Road South Topo cs EPSG:27200 #NZ Map Grid 1949 bitmap ./Surface/Canaan_South_Topo_NZMG_990210_020240.jpg \ [0 0 2499000 6021000 100 100 2502000 6024000] grid-units meter # grid <origin x> <origin y> <x spacing> <y spacing> <x count> <y count> # grid-flip (none)/vertical/horizontal # [grid data] endsurface . endsurvey I have tried reducing the co-ords to the NE corner of the image, and seem to get a more legible, bur still erroneous, surface image. Makes me suspect I'm exceeding some software limits and there's an unreported error, or that I'm just making a dumb mistake. A possibly related matter, I have had "sketches on" (no quote marks) in my layout since my first (almost) Therion steps last year, and not once have I had my jpg sketches exported to pdf. I expect they should, and I recall that the samples provided seem to do so - I could find no difference between my code and the samples. Any ideas on these two issues? (surfaces most importantly) Also the above code does not produce a 3D lox model. Is that because a surface is either 2D or 3D but not both? It would be nice to have at least a 2D image above my lox model until I can get a grillage of elevations sorted. Regards Bruce

Sketches Export -sketch option missing from th2
by Bruce Mutton 17 Apr '08

17 Apr '08

A while back I asked I have had "sketches on" (no quote marks) in my layout since my first (almost) Therion steps last year, and not once have I had my jpg sketches exported to pdf. I expect they should, and I recall that the samples provided seem to do so - I could find no difference between my code and the samples. Stacho replied Do you have -sketch option specified in your scrap? It does not work automatically. In the scrap toolbar - last list box is background sketches. You need to click insert button below and then click on the appropriate picture. Then this picture should be listed in the "background sketches" listbox. Background images in xtherion are not seen by therion, you need to enable this manually. And I replied with what I now realize is nonsense so I won't repeat it. And now I've given this some more time I still have the problem that sketches are not exported, but I have some insight as to why. . Stacho's response above is consistent with the Therion book pg 20 and 32 explanations, and on studying the morphing sample code that comes with the installation, I think that I have been, and still are, following the instructions for the required actions within the map editor perfectly. (and I can see and trace my sketches as expected) However on studying the text files produced by my map editor efforts, and those in the morphing sample I see that the -sketch option is missing from my *.th2 files. >From the Therion book. sketch <filename> <x> <y> . underlying sketch bitmap specification (lower left corner coordinates). So in theory I could manually add this option using the text editor, but there is a difficulty calculating the x, y co-ordinates. I suppose it could be done by hand or by trial and error, but very time consuming. Am I missing something, or is there something my map editor is not translating correctly? Bruce

Encoding Simpleton
by Bruce Mutton 17 Apr '08

17 Apr '08

All the Windows applications I have do not recognise line feeds the way Xtherion does. They display Therion data files as one continuous stream of characters. I think it's probably as easy as changing the default encoding, but as I only speak one language, my knowledge is deficient in this area. I have no idea what I should change it to, ASCII would seem to be a good choice, but despite the Therion book saying it is supported, it does not appear in the drop down list in XTherion. Is there a way of enabling cross compatibility between Therion data files and Windows plain text editors or say Visual Basic editors in Windows, set up to use English (US, UK or NZ)?

new symbol for therion : a hammer
by Gilbert Fernandes (mailinglist) 16 Apr '08

16 Apr '08

hello, I would like to add a new symbol in my survey. A hammer. In France we use it to show place where we dig. I've wrote the Meta Post code, but I've not test it yet (I must first find the doc I have read on therion building to add a new symbol). Could you add it in the next therion release if my code is correct ? Thanks, code metapost def p_entrance_MY (expr P,R,S,A)= T:=identity aligned A rotated R scaled S shifted P; thfill (u,-.9u)--(-.1u,.3u)--(.2u,.6u)--(-.2u,u)--(.2u,-u)--(.6u,-.2u)--(.1u,-.3u)--(-.9u,-u)--cycle; enddef; initsymbol("p_hammer"); let p_hammer = p_hammer; endcode PS : I sent an drawing of the symbol as a join image

color centerlines by map?
by Jonathan Prouty 14 Apr '08

14 Apr '08

I'm wondering how to make it so that each individual map will have a uniquely colored centerline? This would be very helpful for differentiating between different surveys at a glance. In the following example, I would like to to have clay_splay and clay_center be drawn in different colors. The map that I am selecting in thconfig is clay_main, by the way. <code> map clay_splay -proj plan splay.trip2 splay.trip3 endmap map clay_center -proj plan center.trip2 center.trip3 endmap map clay_main clay_splay clay_center endmap clay_main </code> I've attached a PDF that shows roughly what I have in mind, although the alternating blue and green is not necessary. They can both be the same color, as long as that color isn't the same as the centerline :-). Does there happen to be a metapost wizard out there who might have an idea? Thanks in advance! -- -Jonny ^v^

Splay Survey Legs
by Jonathan Prouty 09 Apr '08

09 Apr '08

Hello All, I was wondering if there is any specific reason why Survex's "splay" flag is not supported in Therion? The only way I can get splay shots to not count towards my total length is by flagging them as surface survey or as duplicate survey, which is inaccurate. Any ideas? -Jonny P.S. I'm using version 0.5.1 on windows.
