DESCRIPTION

v.out.png exports a GRASS vector map in non-georeferenced Portable Network Graphics (PNG) image format, respecting the current region resolution and bounds. By default it look for a color table, set using v.colors you can also set the attribute table where read the feature color.

Optionally the user can choose to export a World File (.wld) to provide basic georeferencing support using the -w flag.
