NAME
       pamdice - slice a Netpbm image into many horizontally and/or vertically

EXAMPLE
	   $ pamdice myimage.ppm -outstem=myimage_part -width=10 -height=8
	   $ pamundice myimage_part_%1d_%1a.ppm -across=10 -down=8 >myimage.ppm

	   $ pamdice myimage.ppm -outstem=myimage_part -height=12 -voverlap=9

SYNOPSIS
       pamdice

       -outstem=filenamestem

       [-width=width]

       [-height=height]

       [-hoverlap=hoverlap]

       [-voverlap=voverlap]

       [-verbose]

       [filename]

       You  can	 use  the minimum unique abbreviation of the options.  You can
       use two hyphens instead of one.	You can separate an option  name  from
       its value with white space instead of an equals sign.

DESCRIPTION
       This program is part of Netpbm(1).

       pamdice reads a PAM, PBM, PGM, or PPM image as input and splits it hor‐
       izontally and/or vertically into equal size pieces and writes them into
       separate	 files as the same kind of image.  You can optionally make the
       pieces overlap.

       See the -outstem option for information on naming of the output files.

       The -width and -height options determine the size of the output pieces.

       pamundice can rejoin the images.	 For finer control, you can also use

       pnmcat.

       One use for this is to make pieces that take  less  computer  resources
       than  the whole image to process.  For example, you might have an image
       so large that an image editor can't read it all	into  memory  or  pro‐
       cesses  it  very	 slowly.   With pamdice, you can split it into smaller
       pieces, edit one at a time, and then reassemble them.

       Another use for this is to print a large image in  small	 printer-sized
       pieces  that  you can glue together.  ppmglobe does a similar thing; it
       lets you glue the pieces together into a sphere.

       If you want to cut pieces from an image individually, not in a  regular
       grid, use pamcut.

OPTIONS
       -outstem=filenamestem
	      This option determines the names of the output files.  Each out‐
	      put file is named filenamestem_y_x.type  where  filenamestem  is
	      the value of the -outstem option, x and y are the horizontal and
	      vertical locations, respectively, in the input image of the out‐
	      put  image,  zero	 being the leftmost and top, and type is .pbm,
	      .pgm, .ppm, or .pam, depending on the type of image.

       -width=width
	      gives the width in pixels of the output images.	The  rightmost
	      pieces  are smaller than this if the input image is not a multi‐
	      ple of width pixels wide.

       -height=height
	      gives the height in pixels of the	 output	 images.   The	bottom
	      pieces  are smaller than this if the input image is not a multi‐
	      ple of height pixels high.

       -hoverlap=hoverlap
	      gives the horizontal overlap in pixels  between  output  images.
	      Each  image  in  a row will overlap the previous one by hoverlap
	      pixels.  By default, there is no overlap.

	      This option was new in Netpbm 10.23 (July 2004).

       -voverlap=voverlap
	      gives the vertical overlap  in  pixels  between  output  images.
	      Each  row	 of  images  will overlap the previous row by voverlap
	      pixels.  By default, there is no overlap.

	      This option was new in Netpbm 10.23 (July 2004).

       -verbose
	      Print information about the processing to Standard Error.

HISTORY
       pamdice was new in Netpbm 9.25 (March 2002).

       Before Netpbm 10.29 (August 2005), there was a limit of 100  slices  in
       each direction.
