DESCRIPTION

       r.out.png exports a GRASS raster map in non-georeferenced PNG image format, respecting the
       current region resolution and bounds.

       Optionally  the  user  can  choose  to export a World File to provide basic georeferencing
       support. When used with the transparency flag this can create images useful for KML,  TMS,
       or  WMS  overlays.  (e.g.  for use in Google Earth or as OpenLayers tiles) If output is to
       stdout, the world file will be called png_map.wld.
