NAME
       pamseq -	generate PAM image of all possible tuple values, in sequence

SYNOPSIS
       pamseq [-tupletype=tupletype] depth maxval

       All  options  can  be abbreviated to their shortest unique prefix.  You
       may use two hyphens instead of one to designate an option.  You may use
       either  white  space  or	 an equals sign	between	an option name and its
       value.

DESCRIPTION
       This program is part of Netpbm(1).

       pamseq generates	a PAM image of a specified depth and specified	maxval
       that  consists of a single row.	The row	consists of one	tuple of every
       possible	value, in order.

       For a depth of one, the order is	simple:	From 0 to maxval,  going  from
       left to right.  For higher depths, the highest numbered plane goes from
       0 to maxval (going left to right) while all the other planes have value
       0.  Then	the sequence repeats except with the next highest plane	set to
       a value of 1, then 2, etc.

OPTIONS
       -tupletype
	      This is the value	of the "tuple_type" attribute of  the  created
	      PAM image.  It can be any	string up to 255 characters.

USAGE
       To  create a simple ramp	of the values 0..255, for input	to various ma-
       trix calculations, try
	 pamseq	1 255
       (Before pamseq existed, pgmramp was  often  pressed  into  service  for
       this).

       To create a PPM color map of all	the possible colors representable with
       a maxval	of 5, do
	 pamseq	3 5 -tupletype=RGB | pamtopnm

       Again, with a modern program based on the  Netpbm  library,  you	 don't
       need the	pamtopnm because a PAM RGB image is equivalent to a PPM	image.

       You can use such	a color	map with pnmremap(1) to	quantize the colors in
       an image.  With the maxval of 5 given in	the example, you get  a	 color
       map  of	the set	of "web	safe" colors as	defined	by Netscape.  Most web
       browsers	guarantee that they can	produce	at least these 216 colors (215
       plus black).

HISTORY
       pamseq was added	to Netpbm in June 2002.
