[GRASS-user] zooming raster before rendering image to png

GRASS GRASS user

Hi, all.

Is it possible to zoom the watershed before rendering into png format. The one that I got is too small to view and use for analysis.

d.mon start=‘cairo’ output=/path/
d.rast map=‘basin_54’
d.mon stop=‘cairo’

Thanks,

d.mon start='cairo' output=/path/

you need to run g.region to set up computational region based on your request.

d.rast map='basin_54'
d.mon stop='cairo'

Thanks Martin for the attention,

please keep discussion on ML.

Even after setting the region to basin produced after running
"r.water.outlet", the rendered image has no change in size.

d.mon start=cairo output='path'
g.region raster=basin_produced_by_r.water.outlet

You set up computation region based on you raster (extent, resolution).

You need to set up extent of your zoom window manully.

g.region n= s= w= e=

Or you cold zoom to your area by `zoom` option (skip all NULL values)
if it's OK for you. See g.region manual for details.
