NAME
       makepr -	create Primitive Rectangles in an image

SYNOPSIS
       makepr [-options]  in_file  out_file  [ out_file2 ]

DESCRIPTION
       makepr  reads  a	 binary	 image	and creates Primitive Rectangles.  The
       Primitive Rectangle is the rectangle whose width	is a constant  (column
       width).	See references for the detail of Primitive Rectangles.

       The  file format	of in_file is binary pbm(5).  The primitive rectangles
       are written on out_file and out_file2, whose file format	are  d4file(4)
       ordinally.  Each	rectangle is denoted by	a 4-tuple, the position	of the
       left-top	corner,	the width, and the height of the rectangle.

       If the option -image is specified, the rectangle	image  is  written  on
       out_file.  The file format of out_file is binary	pbm(5) in this case.

OPTIONS
       -or    Logical  "OR" of black pixels is used at the creation of rectan-
	      gles.  (This is default.)

       -and   Logical "AND" of black pixels is used at the creation of rectan-
	      gles.

       -reverse
	      Reverse black and	white of the input image.

       -cwid N
	      Set  the	width of Primitive Rectangles to N.  The default value
	      is N=16.

       -image Create image file	instead	of rectangle file.

       -box   Fill the inside of rectangle by black. Use this option with -im-
	      age.

       -vert  Create the vertical Primitive Rectangles instead of normal hori-
	      zontal ones.

       -mvec  Create both horizontal and vertical Primitive Rectangles concur-
	      rently.	Horizontal  and	 vertical  rectangles  are  written on
	      out_file and out_file2 respectively.

       -d8    Create 8-dimensional (8-tuple) file. (This is experimental.)

       -llim N
	      Suppress writing Primitive Rectangles each of  whose  height  is
	      less than	N. The default is N=1.

       -ulim N
	      Suppress	writing	 Primitive  Rectangles each of whose height is
	      more than	N. The default is N=32767.
