       output=name [required]
           Name for new PNG file (use ’-’ for stdout)

       compression=integer
           Compression level of PNG file

DESCRIPTION

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

       Optionally  the  user  can  choose  to  export  a  World  File  (.wld)  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 redirected to stdout, the world file will be called png_map.wld.
