[ZOO-Discuss] python gdal numpy array question

[niels hoffmann]

zootribe,

I've got a question about some raster processing using python.
The code below works when I run it standalone, but not if I run it as a
zoo-service.
Does anybody have a clue why not?
<==========>
driver=gdal.GetDriverByName('GTiff')
driver.Register()
ds=gdal.Open(filename, GA_ReadOnly)

cols=ds.RasterXSize
rows=ds.RasterYSize
rain_factor=0.85

r2arr=ds.GetRasterBand(1).ReadAsArray(0,0,cols, rows).astype(float)
r2rainfactor=dot(rain_factor,r2arr)
outputs["Result"]["value"]=str(r2rainfactor[100,100])
<=========>
TRACE : 'NotImplementedType' object is unsubscriptable
TRACE : <type 'exceptions.TypeError'>
Unable to run your python process properly

So I'm trying to do a numpy scalar*array multiplication with the dot
operator, this seems to be working standalone, but not in CGI?

Cheers, Niels
