36.59.55 Postscript
Several options may be set in the postscript driver.
Syntax:
set terminal postscript {} {enhanced | noenhanced}
{color | colour | monochrome}
{blacktext | colortext | colourtext}
{solid | dashed} {dashlength | dl }
{linewidth | lw }
{}
{rounded | butt}
{fontfile [add | delete] ""}
{palfuncparam {,}}
{""} {}
where is landscape, portrait, eps or default; enhanced enables enhanced text mode features
(subscripts, superscripts and mixed fonts). See enhanced (p. 127) for more information. Option
color enables color; blacktext forces all text to be written in black even in color mode; solid draws all
plots with solid lines, overriding any dashed patterns; dashlength or dl scales the length of the dashedline
segments by (which is a floating-point number greater than zero); linewidth or lw scales
all linewidths by ; is defaultplex, simplex or duplex ("duplexing" in PostScript
is the ability of the printer to print on both sides of the same page — don’t set this if your printer can’t
do it); rounded sets line caps and line joins to be rounded; butt is the default, butt caps and mitered
joins; "" is the name of a valid PostScript font; and is the size of the font in
PostScript points. In addition to the standard postscript fonts, an oblique version of the Symbol font,
useful for mathematics, is defined. It is called "Symbol-Oblique".
default mode sets all options to their defaults: landscape, monochrome, dashed, dl 1.0, lw 1.0,
defaultplex, noenhanced, "Helvetica" and 14pt. Default size of a PostScript plot is 10 inches wide
and 7 inches high.
palfuncparam is only available if compiled with pm3d support. It controls how set palette functions
are encoded as gradients in the output. Analytic color component functions (set via set palette
functions) are encoded as linear interpolated gradients in the postscript output: The color component
functions are sampled at points and all points are removed from this gradient which can be
removed without changing the resulting colors by more than . For almost every useful
palette you may savely leave the defaults of =2000 and =0.003 untouched.
eps mode generates EPS (Encapsulated PostScript) output, which is just regular PostScript with some
additional lines that allow the file to be imported into a variety of other applications. (The added lines
are PostScript comment lines, so the file may still be printed by itself.) To get EPS output, use the eps
mode and make only one plot per file. In eps mode the whole plot, including the fonts, is reduced to
half of the default size.
Fonts listed by fontfile or fontfile add encapsulate the font definitions of the listed font from a postscript
Type 1 or TrueType font file directly into the gnuplot output postscript file. Thus, the enclosed font
can be used in labels, titles, etc. See the section postscript fontfile (p. 128) for more details. With
fontfile delete a fontfile is deleted from the list of embedded files.
Examples:
set terminal postscript default # old postscript
set terminal postscript enhanced # old enhpost
set terminal postscript landscape 22 # old psbig
set terminal postscript eps 14 # old epsf1
set terminal postscript eps 22 # old epsf2
set size 0.7,1.4; set term post portrait color "Times-Roman" 14
set term post "VAGRoundedBT_Regular" 14 fontfile "bvrr8a.pfa"
Linewidths and pointsizes may be changed with set style line.
The postscript driver supports about 70 distinct pointtypes, selectable through the pointtype option
on plot and set style line.
