Hi,
I have a CELL (integer) layer.
If I write these lines:
map=raster.RasterNumpy("grassmap")
map.open()
map.close()
I obtain:
File "./r.grow.dir.incl4.py", line 310, in <module>
main()
File "./r.grow.dir.incl4.py", line 133, in main
visited.close()
File
"/usr/local/grass-7.0.svn/etc/python/grass/pygrass/raster/__init__.py",
line 664, in close
self._write()
File
"/usr/local/grass-7.0.svn/etc/python/grass/pygrass/raster/__init__.py",
line 607, in _write
self.tofile(self.filename)
ValueError: 160000 requested and 0 written
if i write:
map=raster.RasterNumpy("grassmap")
map.open()
map=map*1.0
map.close()
it works.
Do the numpy raster object is, by default, a float type?
what I miss?
Many thanks
Ivan
