pkdumpimg

program to dump image content to ascii or std out

SYNOPSIS

Usage: pkdumpimg -i input.txt [-o output]

Options: [-of matrix | line] [-b band] [-e vector | -ulx value -uly value -lrx value -lry value]

Advanced options: [-dx value -dy value] [-r resampling] -srcnodata value -dstnodata value

Description

The utility pkdumpimg dumps the content of a raster dataset to (standard) output (screen or filename). The default is to dump the output in matrix format. Use -of line to dump each pixel value on a separate line, preceded by its position (x and y value). You can specify a bounding box to dump with either the extent of an OGR vector dataset or via the options -ulx -uly -lrx and -lry.

Options

• use either -short or --long options (both --long=value and --long value are supported)
• short option -h shows basic options only, long option --help shows all options

  short	long	type	default	description
  i	input	std::string		input image file
  o	output	std::string		Output ascii file (Default is empty: use stdout
  of	oformat	std::string	matrix	Output format (matrix form or list (x,y,z) form. Default is matrix form
  b	band	int		band index to crop
  e	extent	std::string		get boundary from extent from polygons in vector file
  ulx	ulx	double	0	Upper left x value bounding box (in geocoordinates if georef is true)
  uly	uly	double	0	Upper left y value bounding box (in geocoordinates if georef is true)
  lrx	lrx	double	0	Lower left x value bounding box (in geocoordinates if georef is true)
  lry	lry	double	0	Lower left y value bounding box (in geocoordinates if georef is true)
  dx	dx	double	0	Output resolution in x (in meter) (0.0: keep original resolution)
  dy	dy	double	0	Output resolution in y (in meter) (0.0: keep original resolution)
  r	resampling-method	std::string	near	Resampling method (near: nearest neighbour, bilinear: bi-linear interpolation).
  srcnodata	srcnodata	double		set no data value(s) for input image
  dstnodata	dstnodata	short	0	nodata value for output if out of bounds.

  Usage: pkdumpimg -i input.txt [-o output]
