[GRASS-user] r.import extent=region ignored

[Veronica Andreo]

Hello Thomas,

If the map you are importing has the same projection than the location,
then extent parameter is ignored. It is not a bug, but how the module
works. It is written in the 'Notes' section, I think. The extent parameter
works only when map and target location have different reference systems.

Best,
Vero

Hello,

Using GRASS 7.2.1svn r70842 (Linux 64bit from today's binary snapshot) and
it seems the extent=region parameter of the r.import is just ignored. Tried
from GUI, then from command line, first with multi band virtual raster,
then with single JPEG2000 file (as in the example below), with and without
the -n option. Is it a known bug, or does it work for someone, perhaps in
some other version, or with other input formats? I tried to look in trac,
but did not see anything. I am aware how I can clip the rasters after
import, but it seemed one of the fine new features which would make the
daily use a little more comfortable...
