Transparent map-images
by Bruce Mutton 08 Jul '09

08 Jul '09

Hi All Michael and I are putting some large scanned map-images on our therion pdf plots, but near the point where they overlap, one always overwrites the other. We'd rather they be transparent so one map-image can be seen through the other. Will it help if I can figure out how to make the white background of the original scans transparent? Does anyone have any tips for making the white area of a jpg or pdf image transparent? I have access to Adobe Elements, but I'm not very good with it, and although there are instructions for doing this I didn't have much luck comprehending what was required. Regards Bruce

Loch Makefile
by Martin Luethi 14 Jun '09

14 Jun '09

Hi There are some weird settings in the Loch Makefile for the VTK variables. It seems that VTKPATH is used to mean VTKINCLUDEPATH, but also for VTKLIBPATH, which causes problems. Here is a better version (only for target Debian) Best, Martin # PLATFORM DEBIAN CXX = c++ CC = gcc POBJECTS = lxR2P.o VTKPATH = /usr/local VTKINCLUDEPATH = $(VTKPATH)/include/vtk-5.2 VTKLIBPATH = $(VTKPATH)/lib/vtk-5.2 VTKLIBS = -lvtkHybrid -lvtkImaging -lvtkIO -lvtkGraphics -lvtkFiltering -lvtkCommon -lfreetype CXXPFLAGS = -DLXLINUX $(shell wx-config --cxxflags) -Wno-deprecated $(shell freetype-config --cflags) -I$(VTKINCLUDEPATH) CCPFLAGS = -DLXLINUX $(shell wx-config --cflags) LXLIBDIR = linux PLIBS = $(shell wx-config --libs --gl-libs) -L$(VTKLIBPATH) $(VTKLIBS) -lGLU -lpthread -lz LXPLATFORM = LINUX

How to compile without Loch
by Bill Gee 10 Jun '09

10 Jun '09

Hello everyone - I have been struggling for two days trying to get Therion 5.2 (stable) to compile on my brand new CentOS 5.3 system. The dependencies are killing me! CentOS repositories do not include any VTK packages, so I had to build VTK 5.4 from source. That brought its own set of dependencies - I had to compile CMake from source before I could compile VTK! Sheesh!!! This is ridiculous ... Anyhow, the message I am stuck on now comes from "make install" of Therion. It appears to be related to some missing piece of VTK. Can anyone shed some light on how I deal with this? ============== c++ -o loch -Wall lxR2P.o lxTR.o lxOGLFT.o lxSetup.o lxRender.o lxWX.o lxImgIO.o lxLRUD.o lxFile.o lxData.o lxMath.o lxSView.o lxSScene.o lxGUI.o lxGLCo.o lxGLCs.o lxOptDlg.o lxAboutDlg.o img.o -lwx_gtk2u_gl-2.8 -pthread -lwx_gtk2u_richtex t-2.8 -lwx_gtk2u_aui-2.8 -lwx_gtk2u_xrc-2.8 -lwx_gtk2u_qa-2.8 -lwx_gtk2u_html-2. lwx_gtk2u_adv-2.8 -lwx_gtk2u_core-2.8 -lwx_baseu_xml-2.8 -lwx_baseu_net-2.8 - lwx_baseu-2.8 -L/usr/include/vtk-5.0/lib/vtk -lvtkHybrid -lvtkImaging -lvtkIO - lvtkGraphics -lvtkFiltering -lvtkCommon -lfreetype -lpthread -lz -s /usr/bin/ld: cannot find -lvtkHybrid collect2: ld returned 1 exit status make[1]: *** [loch] Error 1 make[1]: Leaving directory `/Installs/therion/loch' make: *** [loch/loch] Error 2 =============== Searching the system for files like "vtkHybrid*" finds vtkHybrid.CMake in the source directory for VTK. I don't find anything else on the system. At the end Therion is not installed. I don't need Loch. Is there a directive for make to tell it to ignore Loch? Thanks - Bill Gee

therion 5.2.9
by Bruce Mutton 02 Jun '09

02 Jun '09

Hi Just tried out 5.2.9 and, while it worked fine, I noticed a few new things; 1. There's now a filter for surveys. What does it filter? Makes no change to my data and nothing in the Therion Book yet. 2. There are a few new warnings in 5.2.9 not present in 5.2.8; Warning: cannot open font map file psfonts.map, and Warning: the turningnumber algorithms do not agree. The current computed value is 0, but the 'connect-the-dots' algorithm returned -1 See the attached log files. Are these of concern? Or suggest something that I should be doing differently? 3. This is probably not a 5.2.9 thing, but does it suggest that my cave has nearly reached Therions ability to create the pdf? PDF statistics: 750 PDF objects out of 1000 (max. 8388607) 7 named destinations out of 1000 (max. 131072) 1967 words of extra memory for PDF output out of 10000 (max. 10000000) Ie 750 objects out of 1000 which maybe signifies three quarters of capacity? The part of the cave processed is about 2% of current surveyed length, and the survey and map structure will be getting much more complex before we are finished. Is there something we should be doing differently so as not to reach 'maximum capacity' before we finish our map? Regards Bruce

Hello, All. XTherion have ability to transparent display the xvi over sketch image. How to bring sketch and xvi to same scale to combine it in XTherion? Now I iterative pick up scale of image in graphic editor, but it is very tedious... PS: Sketches is drawn "in scale", and scaned at 200 or 300 dpi -- WBR, Vasily 31 мая 2009 г.

Bitmap calibration
by mara 12 May '09

12 May '09

Hi, I am having some trouble in calibrating a bitmap image to be used as surface layer. I believe this is quite a basic problem but I havn't find anything in the archives. I need to insert data of 2 different points, so entrance of the cave is 0 0 and I can get the relevant bitmap pixels data from a software like Microsoft Paint. Now, the question is how should I get the data for the second point? I have no knowledge of where the stations are compared to the surface. Sorry but I'm really new to coordinates, GIS and all this stuff....and wonder how to proceed. And also, to make sure the scale is correct I should just export tha map with same scale as the surface map scanned, is this correct or I am missing something? thanks a lot for yr help Best Andrea Arriva Tiscali Mobile!
