.TH HPGL2PS (1L) "25 September 1987"
.SH NAME
hpgl2ps - A HP (Hewlet Packard) plot command filter to PostScript
.SH SYNOPSIS
\fBhpgl2ps\fR
[\fB-amr\fR]
[\fB-l \fIline sizes\fR]
[\fB-s \fIscale\fR]
[\fB-x \fIoffset\fR]
[\fB-y \fIoffset\fR]
[\fIplotfile\fR]
.SH DESCRIPTION
This filter is used to convert the Hewlet Packard Graphic Language (HP-GL)
9873C plotter commands to PostScript. The HP-GL commands are a subset of the
Roland plotter command set (RD-GL).
.PP
The default conditions for \fBhpgl2ps\fR are:
.TP
.B 1.
The plot translation is from ISO A3 (420mm x 297mm) to ISO A4
(297mm x 210mm) on the LaserWriter.
.TP
.B 2.
Line thicknesses are in millimeters and are for lines (pens) 1 to 9:
( 0.1, 0.2, 0.3, 0.4, 0.5, 0.7, 1.0, 1.25, 1.5 )
.TP
.B Note:
If the plotfile is not specified then standard input is assumed.
.SH ARGUMENTS
.TP
.B -a
Draw on an A4 ISO (297mm x 210mm) sheet of paper. This will give an
aproximate 1:1 translation to the LaserWriter.
.TP
\fB-l \fIline sizes\fR
This option allows the default line sizes to be replaced with different
sizes starting from line (pen) one through nine. The new sizes (real or
integer) are entered in a comma seperated string (\fIline size\fR) and
are in millimeters. Only the sizes entered in the string will be
changed with respect to lines (pens) one to nine while nonentered line
(pen) sizes will retain the default sizes.
.sp
In the following example only the first three sizes will be changed.
.sp
eg: hpgl2ps -l 0.4,0.3,1 file | lpr -Plaser1
.TP
.B -m
Enable the manual feed on the LaserWriter (cutoff time 3 minutes).
.TP
.B -r
Rotate plot(s) through 90 degrees. (The plot is made smaller)
.TP
\fB-s\fI scale\fR Scale the plot from 0.1 to 3 times its original
size.
.TP
\fB-x\fI offset\fR Place an X offset (in mm) in the plot.
.TP
\fB-y\fI offset\fR Place an Y offset (in mm) in the plot.
.PP
\fBNote:\fR Offsets are with respect to the 0, 0 (origin) of the HP-GL
/ RD-GL plotting commands, thus if the minimum plotting coordinates are
below either the X and/or Y zero axis then a positive offset is
applied.  Similarly if the minimum plot coordinates are above the X
and/or Y zero axis then a negative offset is applied.

.SH BUGS
Some of the graphics commands are unimplemented and a warning will be
displayed. If this command is vital then it must be written into the code.
.PP
No interactive command is suported.
