DESCRIPTION

54       r.out.png  exports a GRASS GIS raster map in non-georeferenced Portable
55       Network Graphics (PNG) image format, respecting the current region res‐
56       olution and bounds.
57
58       Optionally the user can choose to export a World File (.wld) to provide
59       basic georeferencing support. When used with the transparency flag this
60       can  create  images useful for KML, TMS, or WMS overlays. (e.g. for use
61       in Google Earth or as OpenLayers tiles) If output is redirected to std‐
62       out, the world file will be called png_map.wld.
63

EXAMPLE

65       The example is based on the North Carolina sample data location.
66
67       Export of the soil map to PNG format with world file:
68       g.region raster=soils_Kfactor -p
69       # export PNG file with additional world file
70       r.out.png input=soils_Kfactor output=soils_Kfactor -w
71       # verify
72       gdalinfo soils_Kfactor.png
