It is possible to have whitespace between a command line option and its
parameter.
.
.
.SH DESCRIPTION
.
.B @L_D_PS@
translates the output of
.B @L_TROFF@
to PostScript.
.
It should normally be invoked by using the @L_ROFF@ command
with a
.B \-Tps
option.
.
.if '@DEVICE@'ps' (Actually, this is the default for @T_ROFF@.)
.
If no files are given, the standard input is read.
.
A filename of
.B \-
also causes reading of the standard input.
.
PostScript output is written to the standard output.
.
When
.B @L_D_PS@
is run by
.B @L_ROFF@
options can be passed to
.B @L_D_PS@
using
.BR @L_ROFF@ 's
.B \-P
option.
.
.LP
Note that
.B @L_D_PS@
doesn't produce a valid document structure (conforming to the Document
Structuring Convention) if called with multiple file arguments.
.
To print such concatenated output it is necessary to deactivate DSC
handling in the printing program or previewer.
.
See section
.B FONT INSTALLATION
below for a guide how to install fonts for use with
.BR @L_D_PS@ .
.
.
.SH OPTIONS
.
.TP
.BI \-b n
Provide workarounds for older printers, broken spoolers, and previewers.
.
Normally output at PostScript LanguageLevel\~2 is produced that conforms
to the Document Structuring Conventions version 3.0.
.
Some older printers, spoolers, and previewers can't handle such output.
.
The value of\~\c
.I n
controls what
.B @L_D_PS@
does to make its output acceptable to such programs.
.
A value of\~0 causes @L_D_PS@ not to employ any workarounds.
.
.IP
Add\~1 if no
.B %%Begin\%Document\%Setup
and
.B %%End\%Document\%Setup
comments should be generated;
this is needed for early versions of TranScript that get confused by
anything between the
.B %%End\%Prolog
comment and the first
.B %%Page
comment.
.
.IP
Add\~2 if lines in included files beginning with
.B %!\&
should be stripped out; this is needed for Sun's pageview previewer.
.
.IP
Add\~4 if
.BR %%Page ,
.BR %%Trailer
and
.B %%End\%Prolog
comments should be
stripped out of included files; this is needed for spoolers that
don't understand the
.B %%Begin\%Document
and
.B %%End\%Document
comments.
.
.IP
Add\~8 if the first line of the PostScript output should be
.B %!PS-Adobe-2.0
rather than
.BR %!PS-Adobe-3.0 ;
this is needed when using Sun's Newsprint with a printer that requires
page reversal.
.
.IP
Add\~16 if no media size information should be included in the document
(this is, neither use
.B %%Document\%Media
nor the
.B setpagedevice
PostScript command).
.
This behaviour is needed for older printers which don't understand PostScript
LanguageLevel\~2.
.
It is also necessary if the output is further processed to get an
encapsulated PS (EPS) file \[en] see below.
.
.IP
The default value can be specified by a
.
.RS
.IP
.BI broken\  n
.
.LP
command in the DESC file.
.
Otherwise the default value is\~0.
.RE
.
.TP
.BI \-c n
Print
.I n
copies of each page.
.
.TP
.BI \-F dir
Prepend directory
.IB dir /dev name
to the search path for prologue, font, and device description files;
.I name
is the name of the device, usually
.BR ps .
.
.TP
.BI \-g
Guess the page length.
.
This generates PostScript code that guesses the page length.
.
The guess is correct only if the imageable area is vertically
centered on the page.
.
This option allows you to generate documents that can be printed
both on letter (8.5\[mu]11) paper and on A4 paper without change.
.
.TP
.BI \-I dir
This option may be used to add a directory to the search path for
files on the command line and files named in
.B \[rs]X'ps: import'
and
.B \[rs]X'ps: file'
escapes.
.
The search path is initialized with the current directory.
.
This option may be specified more than once; the directories are then
searched in the order specified (but before the current directory).
.
If you want to make the current directory be read before other directories,
add
.B \-I.\&
at the appropriate place.
.
.IP
No directory search is performed for files with an absolute file name.
.
.TP
.B \-l
Print the document in landscape format.
.
.TP
.B \-m
Turn manual feed on for the document.
.
.TP
.BI \-p paper-size
Set physical dimension of output medium.
.
This overrides the
.BR papersize ,
.BR paperlength ,
and
.B paperwidth
commands in the
.B DESC
file; it accepts the same arguments as the
.B papersize
command.
.
See
.B @L_ROFF@_font (@MAN5EXT@)
for details.
.
.TP
.BI \-P prologue-file
Use the file
.I prologue-file
(in the font path) as the prologue instead of the default prologue file
.BR prologue .
.
This option overrides the environment variable
.SM @U_D_PS@_PROLOGUE.
.
.TP
.BI \-w n
Lines should be drawn using a thickness of
.IR n \~\c
thousandths of an em.
.
If this option is not given, the line thickness defaults to 0.04\~em.
.
.TP
.B \-v
Print the version number.
.
.
.SH USAGE
.
The input to
.B @L_D_PS@
must be in the format output by
.BR @L_TROFF@ (@MAN1EXT@).
.
This is described in
.BR @L_ROFF@_out (@MAN5EXT@).
.
.LP
In addition, the device and font description files for the device used
must meet certain requirements:
.
The resolution must be an integer multiple of\~72 times the
.BR sizescale .
.
The
.B ps
device uses a resolution of 72000 and a sizescale of 1000.
.
.LP
The device description file must contain a valid paper size; see
.BR @L_ROFF@_font (@MAN5EXT@)
for more information.
.
.LP
Each font description file must contain a command
.IP
.BI internalname\  psname
.LP
which says that the PostScript name of the font is
.IR psname .
.
It may also contain a command
.IP
.BI encoding\  enc_file
.LP
which says that
the PostScript font should be reencoded using the encoding described in
.IR enc_file ;
this file should consist of a sequence of lines of the form:
.IP
.I
pschar code
.LP
where
.I pschar
is the PostScript name of the character,
and
.I code
is its position in the encoding expressed as a decimal integer; valid
values are in the range 0 to\~255.
.
Lines starting with
.B #
and blank lines are ignored.
.
The code for each character given in the font file must correspond
to the code for the character in encoding file, or to the code in the default
encoding for the font if the PostScript font is not to be reencoded.
.
This code can be used with the
.B \[rs]N
escape sequence in
.B troff
to select the character,
even if the character does not have a @T_ROFF@ name.
.
Every character in the font file must exist in the PostScript font, and
the widths given in the font file must match the widths used
in the PostScript font.
.
.B @L_D_PS@
assumes that a character with a @T_ROFF@ name of
.B space
is blank (makes no marks on the page);
it can make use of such a character to generate more efficient and
compact PostScript output.
.
.LP
Note that
.B @L_D_PS@
is able to display all glyphs in a PostScript font, not only 256.
.I enc_file
(or the default encoding if no encoding file specified) just defines the
order of glyphs for the first 256 characters; all other glyphs are
accessed with additional encoding vectors which are produced on the fly.
.
.LP
can automatically include the
Downloadable fonts necessary to print the document are automatically
downloaded.
.
Such fonts must be in PFA format.
.
Use
.BR \%@L_PFBTOPS@ (@MAN1EXT@)
to convert a Type\~1 font in PFB format.
.
Any downloadable fonts which should, when required, be included by
.B @L_D_PS@
must be listed in the file
.BR @FONTDIR@/ps/download ;
this should consist of lines of the form
.
.IP
.I
font filename
.
.LP
where
.I font
is the PostScript name of the font,
and
.I filename
is the name of the file containing the font;
lines beginning with
.B #
and blank lines are ignored;
fields may be separated by tabs or spaces;
.I filename
is searched for using the same mechanism that is used
for @T_ROFF@ font metric files.
.
The
.B download
file itself is also searched for using this mechanism;
currently, only the first found file in the font path is used.
.
.LP
If the file containing a downloadable font or imported document
conforms to the Adobe Document Structuring Conventions,
then
.B @L_D_PS@
interprets any comments in the files sufficiently to ensure that its
own output is conforming.
.
It also supplies any needed font resources that are listed in the
.B download
file
as well as any needed file resources.
.
It is also able to handle inter-resource dependencies.
.
For example, suppose that you have a downloadable font called Garamond,
and also a downloadable font called Garamond-Outline
which depends on Garamond
(typically it would be defined to copy Garamond's font dictionary,
and change the PaintType),
then it is necessary for Garamond to appear before Garamond-Outline
in the PostScript document.
.
This is automatically handled
provided that the downloadable font file for Garamond-Outline
indicates its dependence on Garamond by means of
the Document Structuring Conventions,
for example by beginning with the following lines
.
.IP
.B
%!PS-Adobe-3.0 Resource-Font
.br
.B
%%DocumentNeededResources: font Garamond
.br
.B
%%EndComments
.br
.B
%%IncludeResource: font Garamond
.
.LP
In this case both Garamond and Garamond-Outline would need to be listed
in the
.B download
file.
.
A downloadable font should not include its own name in a
.B %%Document\%Supplied\%Resources
comment.
.
.LP
.B %%Document\%Fonts
comments are not interpreted.
.
The
.BR %%Document\%Needed\%Resources ,
.BR %%Document\%Supplied\%Resources ,
.BR %%Include\%Resource ,
.BR %%Begin\%Resource ,
and
.BR %%End\%Resource
comments
(or possibly the old
.BR %%Document\%Needed\%Fonts ,
.BR %%Document\%Supplied\%Fonts ,
.BR %%Include\%Font ,
.BR %%Begin\%Font ,
and
.BR %%End\%Font
comments)
should be used.
.
.LP

There are also some special fonts called
.B S
for the PS Symbol font, and
.BR SS ,
containing slanted lowercase Greek letters taken from PS Symbol.
.
Zapf Dingbats is available as
.BR ZD ,
and a reversed version of ZapfDingbats (with symbols pointing in the opposite
direction) is available as
.BR ZDR ;
most characters in these fonts are unnamed and must be accessed using
.BR \[rs]N .
.
.LP
The default color for
.B \[rs]m
and
.B \[rs]M
is black; for colors defined in the `rgb' color space
.B setrgbcolor
is used, for `cmy' and `cmyk'
.BR setcmykcolor ,
and for `gray'
.BR setgray .
.
Note that
.B setcmykcolor
is a PostScript LanguageLevel\~2 command and thus not available on some
older printers.
.
.LP
Various X\~commands produced using the
.B \[rs]X
escape sequence are understood, of which only commands that begin with a
.B ps:
tag are interpreted.
.
.TP
.BI \[rs]X'ps:\ exec\  code '
This executes the arbitrary PostScript commands in
.IR code .
.
The PostScript currentpoint is set to the position of the
.B \[rs]X
command before executing
.IR code .
.
The origin is at the top left corner of the page,
and y\~coordinates increase down the page.
.
A procedure\~\c
.B u
is defined that converts @T_ROFF@ units
to the coordinate system in effect (provided the user doesn't change the
scale).
.
For example,
.
.RS
.IP
.B
\&.nr x 1i
.br
.B
\[rs]X'ps: exec \[rs]nx u 0 rlineto stroke'
.br
.RE
.

.I code
may make changes to the graphics state,
but any changes persist only to the end of the page.
.
A dictionary containing the definitions specified by the
.B def
and
.B mdef
is on top of the dictionary stack.
.
If your code adds definitions to this dictionary,
you should allocate space for them using
.BI \[rs]X'ps\ mdef \ n '\fR.
.
Any definitions persist only until the end of the page.
.
If you use the
.B \[rs]Y
escape sequence with an argument that names a macro,
.I code
can extend over multiple lines.
.
For example,
.
.RS
.IP
.nf
.ft B
\&.nr x 1i
\&.de y
\&ps: exec
\&\[rs]nx u 0 rlineto
\&stroke
\&..
\&\[rs]Yy
.ft R
.fi
.
.LP
is another way to draw a horizontal line one inch long.
.
Note the single backslash before `nx' \[en] the only reason to use a number
register while defining the macro `y' is to convert a user-specified
dimension `1i' to internal @T_ROFF@ units which are in turn converted to PS
units with the
.B u
procedure.
.
.LP
.B @L_D_PS@
wraps user-specified PostScript code into a dictionary, nothing more.

respectively.

This must be supplied by the user, if necessary.

.BI \[rs]X'ps:\ def\  code '
Place a PostScript definition contained in

There should be at most one definition per

command.
.
Long definitions can be split over several
.B \[rs]X

all the

.
The definitions are placed in a dictionary which is automatically
pushed on the dictionary stack when an

The arguments
.IR llx ,
.IR lly ,
.IR urx ,

.I ury
give the bounding box of the graphic in the default PostScript
coordinate system; they should all be integers;
.I llx
and
.I lly
are the x and y\~coordinates of the lower left
corner of the graphic;
.I urx

are the x and y\~coordinates of the upper right corner of the graphic;
.I width
and
.I height
are integers that give the desired width and height in @T_ROFF@
units of the graphic.
.
.IP
The graphic is scaled so that it has this width and height
and translated so that the lower left corner of the graphic is
located at the position associated with
.B \[rs]X
command.
.
If the height argument is omitted it is scaled uniformly in the
x and y\~directions so that it has the specified width.
.
.IP
Note that the contents of the
.B \[rs]X
command are not interpreted by

so vertical space for the graphic is not automatically added,
and the
.I width

font wrappers and well-formed AFM files that can be fed to
the

Another solution for creating type42 wrappers is to use FontForge,
available from
.UR http://\:fontforge.sf.net
http://\:fontforge.sf.net
.UE .
This font editor can convert most outline font formats.

This section gives a summary of the above explanations; it can serve
as a step-by-step font installation guide.

Convert your font to something @T_ROFF@ understands.
.
This is either a PostScript Type\~1 font in PFA format or a
PostScript Type\~42 font, together with an AFM file.
.
.IP
The very first characters in a PFA file look like this:
.
.RS
.IP
.B %!PS-AdobeFont-1.0:
.RE
.
.IP
A PFB file has this also in the first line, but the string is
preceded with some binary bytes.
.
.IP
The very first characters in a Type\~42 font file look like this:
.
.RS
.IP
.B %!PS-TrueTypeFont
.RE
.
.IP
This is a wrapper format for TrueType fonts.
.
Old PS printers might not support it (this is, they don't have a
built-in TrueType font interpreter).
.
.IP
If your font is in PFB format (such fonts normally have `.pfb' as
the file extension), you might use
.BR \%@L_PFBTOPS@ (@MAN1EXT@)
program to convert it to PFA.
.
For TrueType fonts, try
.B ttftot42
or
.BR fontforge .
For all other font formats use
.B fontforge
which can convert most outline font formats.
.
.LI
Convert the AFM file to a font description file with the
.BR \%@L_AFMTODIT@ (@MAN1EXT@)
program.
.
An example call is
.
.RS
.IP
@L_AFMTODIT@ Foo-Bar-Bold.afm textmap FBB
.RE
.
.IP
which converts the metric file `Foo-Bar-Bold.afm' to the @T_ROFF@
font `FBB'.
.
If you have a font family which comes with normal, bold, italic,
and bold italic faces, it is recommended to use the letters
.BR R ,
.BR B ,
.BR I ,
and
.BR BI ,
respectively, as postfixes in the @T_ROFF@ font names to make the
`.fam' request work.
.
An example is the built-in Times-Roman font: The font family name
is
.BR T ,
and the font names are
.BR TR ,
.BR TB ,
.BR TI ,
and
.BR TBI .
.
.LI
Install both the font description files and the fonts in a
`devps' subdirectory of the font path which @T_ROFF@ can find.
.
See the
.B ENVIRONMENT
section in the
.BR @L_TROFF@ (@MAN1EXT@)
man page which lists the actual value of the font path.
.
Note that @T_ROFF@ doesn't use the AFM files (but it is a good idea to
store them anyway).
.
.LI
Register all fonts which must be downloaded to the printer in the
`devps/download' file.
.
Only the first occurrence of this file in the font path is read.
.
This means that you should copy the default `download' file to the
first directory in your font path and add your fonts there.
.
To continue the above example we assume that the PS font name for
Foo-Bar-Bold.pfa is `XY-Foo-Bar-Bold' (the PS font name is stored in the
.B internalname
field in the `FBB' file), thus the following line should be added to
`download'.
.
.RS
.IP
.B XY-Foo-Bar-Bold Foo-Bar-Bold.pfa
.
.RE

.SH ENVIRONMENT
.

.SM
.B @U_D_PS@_PROLOGUE
If this is set to
.IR foo ,
then
.B @L_D_PS@
uses the file

.BR prologue .
.
The option
.B \-P
overrides this environment variable.
