  short	long	type	default	description
  i	input	std::string		Input image file
  m	mask	std::string		All pixels in the mask band with a value other than zero will be considered suitable for collection as polygons. Use input file as mask to remove background polygon!
  o	output	std::string		Output vector file
  f	f	std::string	SQLite	Output OGR file format
  b	band	int	0	the band to be used from input file
  nodata	nodata	double		Disgard this nodata value when creating polygons.
  n	name	std::string	DN	the field name of the output layer
