Hi all,
WinXP SP2
Grass installed using: WinGRASS-6.4.0SVN-r38537-1-Setup.exe
I am working on creating a simple batch file that takes in a GeoTIFF,
creates a new Location, does some work on the image and then spits out the
final product.
I started by copying the environment setup commands from
$GISBASE\grass64.bat and removed the call to $GISBASE\etc\Init.bat.
I started by adding in a call to
g.proj.exe -pc georef=<path to image> location=test
and verified that a new location named "test" was placed in my $GISDATA
directory, including the PERMANENT folder and the DEFAULT_WIND, PROJ_INFO,
PROJ_UNITS, and WIND files.
Then I added in
r.in.gdal.exe input=<path to image> output=aerial
and verified that it created aerial.red, aerial.green, aerial.blue, and
aerial.4.
When I added the command to create an RGB
r.composite.exe red=aerial.red green=aerial.green blue=aerial.blue levels=1
output=aerial
I got an error telling me to set the region using r.region.
So I added in
r.region map=aerial.red
to set the region based on the size of the red channel.
When I ran this, all of the executables started throwing unhandled
exceptions (stack overflow, divide by zero, etc.) So I started removing
commands in the batch until only the g.proj.exe command remained and I was
still getting unhandled exceptions.
At this point I decided to restart my computer and reinstall GRASS. Now
when I run the batch file, none of the commands do anything. Even
g.proj.exe -help shows nothing in the command window.
Has anyone run into this, or know of a workaround/fix to this issue?
The commands all work in the GUI, so I am not sure why they won't work in a
batch file.
Thanks for your time!
Ben

I have installed GRASS for windows (the latest 6.4 version). Everything
seems to be working fine when I'm using the wxpython gui. When i switch to
the tcltk GUI, none of my data show up. I end up with an empty project even
though I can see that there is data when i use the python gui.
The second probleme is when i try to create a profile I get the following
error:
Traceback (most recent call last):
File "C:\GRASS\Python25\lib\profile.py", line 466, in
OnCreateProfile
File "C:\GRASS\Python25\lib\profile.py", line 393, in
SetGraphStyle
File "C:\Programs\GIS\OSGeo4W\apps\Python25\lib\site-
packages\wx-2.8-msw-unicode\wx\_gdi.py", line 114, in
__init__
TypeError
:
in method 'new_Colour', expected argument 1 of type 'byte'
The funny part is sometime it works fine and sometime I get the above error
off and on on the same Raster file.
Thanks
