NAME

SYNOPSIS

DESCRIPTION

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 rectangles. (This is default.)

-and

Logical "AND" of black pixels is used at the creation of rectangles.

-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 -image.

-vert

Create the vertical Primitive Rectangles instead of normal horizontal ones.

-mvec

Create both horizontal and vertical Primitive Rectangles concurrently. 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.
