   Parameters:
       input=name
           Name of input raster map

       output=name
           Name for new PNG file (use out=- for stdout)
           Default: .png

       compression=integer
           Compression level of PNG file
           (0 = none, 1 = fastest, 9 = best)
           Options: 0-9
           Default: 6

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.
