[GRASS-dev] gis.m - resolution change not adapted in map display

Hi,

in my grass 6.2 version changing resolution of a map with the gis.m is
not adapted to the map display. The region is changed (written in the output of
gis.m) but in the map display old values remain.

do others have the same problem?

example:

start working in gis.m:

- display a map (e.g: geology,spearfish)
- change region to res=200
- click on redraw in the mao display

kind regards,
  Otto

Have you tried to "zoom to the current region" ?
Which display mode are you using ?

Otto,

This is exactly how it is supposed to work. Changing the display region does
not automatically change the computational region, and changing the
computational region (via g.region) does not automatically change the
display. These are independent. Also, each display has its own independent
display region.

If you want the display to match a new computational region, select the
option from the zoom pulldown on the display you want to match (set display
to match current region). If you want the computational region to match any
open display, select the option from the zoom pulldown (set region to match
display).

Hope this helps explain.

Michael

Ahh, I was just a little confused because it is diffrent from using
the command line:

g.region res=200 and redraw with d.erase ; d.rast geology ...

but of course it works as you described with "zoom to the current region".

thanks a lot
Otto
