HPGL2PS((1L)) HPGL2PS((1L)) 21 July 1989 NAME hpgl2ps - A HP (Hewlet Packard) plot command filter to PostScript SYNOPSIS hpgl2ps [-AB43mr] [-l line sizes] [-s scale] [-x offset] [-y off_ [-h font height multiplier] [-w font width multiplier] [plotfile] DESCRIPTION This filter is used to convert Hewlet Packard Graphic Language (HP-GL) 7550A plotter commands to PostScript. The HP-GL commands are a subset of the Roland plotter command set (RD-GL). The default conditions for hpgl2ps are: A. The plot translation is from an ANSI A (8.5 x 11inch) plot to ANSI A paper on the LaserWriter. See below for other paper sizes. B. 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 ) C. The default font is Helvetica, 14 point on the Laserwriter. D. The default font height and width multipliers are 1.2 and 3.6 respectively. Note: If the plotfile is not specified then standard input is assumed. ARGUMENTS -A Draw for an ANSI A (11 x 8.5inch) plot. -B Draw for an ANSI B (17 x 11inch) plot. -4 Draw for an A4 ISO (297mm x 210mm) plot. This will give an aproximate 1:1 translation to the LaserWriter. -3 Draw for an A3 ISO (420mm x 297mm) plot. -l line sizes 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 (line size) 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. In the following example only the first three sizes will be changed. - 1 - Formatted: March 6, 1996 HPGL2PS((1L)) HPGL2PS((1L)) 21 July 1989 eg: hpgl2ps -l 0.4,0.3,1 file | lpr -Plaser1 -m Enable the manual feed on the LaserWriter (cutoff time 3 minutes). -r Rotate plot(s) through 90 degrees. (The plot is made smaller) -s scale Scale the plot from 0.1 to 3 times its original size. -w relative font width multiplier When the SR command exists in the HP-GL file, the size of characters is scaled to be a proportion of the paper dimensions. The HP7550 plotter character sizes are larger than the scaling suggests. The default value of the font width multiplier scales the characters in the postscript file to appear roughly the same width as the original. Setting to 1.0 reverts to the original scaling. -w relative font height multiplier When the SR command exists in the HP-GL file, the size of characters is scaled to be a proportion of the paper dimensions. The HP7550 plotter character sizes are larger than the scaling suggests. The default value of the font height multiplier scales the characters in the postscript file to appear roughly the same width as the original. Setting to 1.0 reverts to the original scaling. -x offset Place an X offset (in mm) in the plot. -y offset Place an Y offset (in mm) in the plot. Note: 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.
