- lib64wxPythonGTK2.8 lib64wxPythonGTK2.8-devel wxPythonGTK wxPythonGTK-wxversion
-
- MS-WINDOWS ONLY REQUIREMENTS
-
- Python Extensions for MS-Windows >= Build 210
-
- Get Python Extensions for MS-Windows from:
- http://sourceforge.net/project/platformdownload.php?group_id=78018
- Get NumPy from:
- http://sourceforge.net/project/showfiles.php?group_id=1369&package_id=175103
- 2 - STARTUP WITH GRASS INITIALIZATION
- If you want to launch wxPython GUI automatically, start GRASS with
- `-gui` parameter
- $ grass70 -gui
- 3 - STARTUP FROM GRASS TERMINAL
- Simply run
- $ g.gui wxpython
- from the GRASS terminal.
- You can also specify workspace file to load on startup.
- $ g.gui gui=wxpython workspace=myworkspace.gxw
- 4 - DEBUGGING
- To enable GUI debug messages on given level set WX_DEBUG environment
- variable, e.g.
- $ g.gisenv set="WX_DEBUG=3"
- 5 - CLI Display scripts
- Note: This section is out-dated!
- This is going to be replacement for command line tools like d.rast and
- d.vect.
- Now add directory "scripts" in gui directory to your $PATH. These
- little programs should later go to GRASS Scripts directory or became
- Python scripts or C programs. Now they are only small BASH wrappers
- which can be easily and fast customized.
- $~ export PATH=scripts/:$PATH
- Start GRASS:
- $~ grass70 ~/grassdata/spearfish60/user1
- Use command p.mon (shell script in gui/scripts directory) to start map
- display:
- GRASS> p.mon anything
- After a while, new window should appear. If this is your case, add some
- raster layer to the map display:
- GRASS> p.rast aspect
- What about a bit transparency?
- GRASS> p.rast elevation.dem opacity=0.5
- And try the vector layer too
- GRASS> p.vect roads
- NOTE: only map name is currently supported. No other option will influence
- the map layout
- Alternatively you can use more universal p.cmd:
- GRASS> p.cmd "d.rast map=elevation.dem@PERMANENT catlist=1300-1400 -i"
- You should be able to zoom && pan through the map, once the layers are
- displayed. You should be also able to store the display content as well as
- clear the display and start from scratch.
