[GRASS-dev] d.mon x0 (substitution) in wingrass (i.spectral)?

[Helmut Kudrnovsky]

[please keep in mailing list that other can benefit of the solution]

the example in the i.spectral-manual is:
[http://grass.osgeo.org/grass64/manuals/i.spectral.html]

   g.region rast=lsat7_2002_10 -p
   d.mon x0
   d.rast lsat7_2002_40
   i.spectral -i rast=lsat7_2002_10,lsat7_2002_20,lsat7_2002_30,lsat7_2002_40,lsat7_2002_50,lsat7_2002_70

testing this example in osgeo4w-wingrass6.4.3svn, it says "ERROR: No graphic device open (d.mon)",  

AFAIU d.mon x0 isn't available, therefore also " 'd.mon' not yet implemented in the WxGUI".

the d.mon-manual says that other drivers are available, e.g. d.mon start=PNG, but also the message 'd.mon' not yet implemented in the WxGUI".
[http://grass.osgeo.org/grass64/manuals/pngdriver.html]

otherwise in the wx-commandline this works:

d.mon --help

- any idea how to start for example d.mon start=PNG (or other driver working in windows)?
- any idea how i.spectral could work in windows?

best regards
Helmut
