SYNOPSIS¶
r.out.png
r.out.png --help
r.out.png [-tw] input=name
output=name [compression=integer]
[--overwrite] [--help] [--verbose] [--quiet]
[--ui]
Flags:¶
Parameters:¶
- input=name [required]
-
Name of input raster map - output=name [required]
-
Name for new PNG file (use ’-’ for stdout) - 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 GIS 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.
EXAMPLE¶
The example is based on the North Carolina sample data.
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
