.TH CROPMARKS 1 "DWB 3.2"
.SH NAME
.B cropmarks
\- add cropmarks to PostScript files
.SH SYNOPSIS
\*(mBcropmarks\f1
.OP "" options []
.OP "" files []
.SH DESCRIPTION
.B Cropmarks
surrounds PostScript
.I files
with code that centers each page and adds cropmarks to the four
corners.
The results are written on the standard output.
If no
.I files
are specified, or if
.OP \-
is one of the input
.I files,
the standard input is read.
The following
.I options
are understood:
.TP 1.0i
.OP \-d
Disable the device-dependent PostScript code that expands page sizes.
.TP 1.0i
.OP \-h num
Set the height of each page to
.I num
inches.
The default is 11.0 inches.
.TP 1.0i
.OP \-s
Scale pages so cropmarks always show up.
Primarily for debugging and development on devices that don't adjust
page sizes.
.TP 1.0i
.OP \-w num
Set the width of each page to
.I num
inches.
The default is 8.5 inches.
.TP 1.0i
.OP \-L file
Use
.I file
as the PostScript prologue.
.br
The default is
.MR \*(dQ/cropmarks.ps .
.PP
Height and width set with the
.OP \-h
and
.OP \-w
options adjust the size of the image area available on each sheet
of paper.
Neither suggests anything about the orientation of output in that area.
Cropmarks are printed at each corner just outside the image area.
.SH EXAMPLES
.PP
Print text in a 6.5\(mu8.0-inch area centered on each sheet of paper:
.EX
troff -mm \f2file\fP | dpost | cropmarks -w6.5 -h8.0 | \f2spool
.EE
Print landscape text in exactly the same 6.5\(mu8.0-inch area:
.EX
troff -mm \f2file\fP | dpost -pland | cropmarks -w6.5 -h8.0 | \f2spool
.EE
In both examples,
.I spool
is the spooling command used to send PostScript output to a local printer.
.SH WARNINGS
.PP
Device-dependent PostScript code to automatically expand page sizes may
only work on Linotronic 200P typesetters that use 12-inch-wide paper.
Local changes to the printer-dependent code can be made in the
.MW expandpagesize
procedure defined in
.MR \*(dQ/cropmarks.ps .
.PP
The PostScript
.I files
must be reasonably well behaved.
There are no guarantees, particularly if the input
.I files
redefine the
.MW showpage
operator.
.PP
The program is unsupported and may not be included in future releases.
