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.
