gdal from within Thuban: strange in German (Re: thuban-1.1.0-4.exe)

[Bernhard Reiter]

I have found something!

gdal behaves faulty when called within Thuban.

My hypothesis now is: 
	Gdal that is not save to the C-library behaving differently.
	within different locales in Windows.

When I set the behaviour of Windows to English (Great Britian),
at two places in the system control and reboot.
Now it works!

My GNU/Linux version with Gdal 1.3.1.0 does not show this behaviour.
We could look for any setlocale calls within Thuban, its libraries and gdal.
Maybe the wrapper should make sure the locale is "C" when calling 
gdal functions.

Didrik,
maybe can you set your locales in Windows to German /Deutsch,
you should also see it fails. This is interesting because then we 
both can work on the fix.



Here are more details:

Windows from within Thuban/Model/layer.py RasterLayer.BoundingBox()
	geotransform= (0, 1, 0, 0, 0, 1)
	rasterlayer.BoundingBox will return: (0, 394, 5002, 0)

GNU/Linux:
geotransform= (-24.550000000000001, 0.002210782287085, 0.0,
66.566666999999995,0.0, -0.0083333350253810001)


Windows, from the command line:

cd c:\programme\thuban\gdal\pymod

c:\python24\python.exe

import gdal, gdalconst
rast = gdal.Open('C:\Programme\Thuban\Data\iceland\island.tif',
gdalconst.GA_ReadOnly)
print rast.GetRasterCount()

is okay!
