[GRASS-dev] Re: gis.m: how to create high-resolution graphics file ?

[Joel Pitt]

Correct me if I'm wrong but isn't that the function of the res parameter?
I think res=4 outputs a png at 4 times the current display size.

d.out.png --help
Description:
 Saves active display monitor to PNG file in home directory
Usage:
 d.out.png output=string [res=value]
Parameters:
  output   Name of PNG file
     res   Resolution of output file (single=1, double=2, quad=4)
           default: 2
