DESCRIPTION
r.out.png exports a GRASS GIS raster map in non-georeferenced Portable
Network Graphics (PNG) image format, respecting the current region res-
olution 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 std-
out, the world file will be called png_map.wld.
EXAMPLE
The example is based on the North Carolina sample data location.
Export of the soil map to PNG format with world file:
g.region raster=soils_Kfactor -p
# export PNG file with additional world file
r.out.png input=soils_Kfactor output=soils_Kfactor -w
# verify
gdalinfo soils_Kfactor.png
