[GRASS-dev] python using grass without starting grass: can we have a wx monitor displaying images?

Hi,

I am starting a recursive process on many images and I would like to display a resulting image for each of the dataset being processed.

The script I am using is a Python script, calling GRASS without grass being run “normally”, and it does process properly, so all is OK.

I am trying like this:
g.run_command(‘d.mon’,start=“wx0”)
g.run_command(‘d.mon’,select=“wx0”)
g.run_command(‘d.rast’,map=toar)

but not display is being launched, though it says “wx0 already selected”…

Am I expecting not available features, or did something wrong?

I wonder if the
g.run_command('d.mon',select="wx0")
is needed at all.

Furthermore, perhaps a DISPLAY redirect is needed (just guessing around)?
