DESCRIPTION

54       r.out.png exports a GRASS raster map in non-georeferenced Portable Net‐
55       work Graphics (PNG) image format, respecting the current region resolu‐
56       tion 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.
