[GRASS-dev] g.region b>t fixed (?)

[Martin Landa]

Hi all,

I have tried to fix b > t g.region bug. Do you think that -p|-p3 flag
should also print information about number of cells/3dcells. It may be
useful information -- from user point of view...

Current behaviour:

GRASS 6.1.cvs (spearfish60):~ >
g.region -d

g.region res3=100 b=100 t=0 -p3
...
tbres:      -inf
...
depths:     0

g.region -p3
ERROR: region for current mapset is invalid
       line 15: <depths: 0>
       run "g.region"

or

g.region -d

g.region t=100 b=0 tbres=500 -p3
...
tbres:      inf
...
depths:     0
...

g.region -p3
ERROR: region for current mapset is invalid
       line 15: <depths: 0>
       run "g.region"

After patching

g.region -d

g.region res3=100 b=100 t=0 -p3
ERROR: Invalid region: Top must be larger than Bottom

g.region -p3
...
top:        1.00000000
bottom:     0.00000000
...
tbres:      1
...
depths:     1
cells:      302418
3dcells:    302418

g.region -d

g.region t=100 b=0 tbres=500 -p3
...
top:        100.00000000
bottom:     0.00000000
...
tbres:      100
...
depths:     1
cells:      302418
3dcells:    302418

If you find the patch useful, please commit it to CVS, thanks.

Best regards, Martin
