.SH NAME
pnmdissect - dissect a portable anymap
.SH SYNOPSIS
.B pnmdissect
.RB [ -adjacency
.IR n ]
.RB [ -minsize
.IR n ]
.RI [ pnmfile ]
.SH DESCRIPTION
Reads a portable anymap as input.
Looks for regions separated by the background color, and writes out
each such region as a separate output file.
.PP
The -adjacency flag specifies how close non-background pixels have to be
to each other in order to be considered part of the same object.
The default is two, meaning they can be separated by one background pixel.
An adjacency of one would mean they would have to be right next to each other.
.PP
The -minsize fiag specifies the minimum size object that will be written out.
Objects smaller than this many pixels in both dimensions will just be
ignored.  The default is 5, so anything smaller than 5x5 is dropped.
