.SH Description
.\" ====================================================================
.
The GNU
.I roff
PDF output driver translates the output of
.MR \%troff 1
into Portable Document Format.
.
Normally,
.I gropdf
is invoked by
.MR groff 1
when the latter is given the
.RB \[lq] \-T\~pdf \[rq]
option.
.
(In this installation,
.B \%ps
is the default output device.)
.
Use
.IR groff 's
.B \-P
option to pass any options shown above to
.IR gropdf .
.
If no
.I file
arguments are given,
or if
.I file
is \[lq]\-\[rq],
.I gropdf
reads the standard input stream.
.
It writes to the standard output stream.
.

.
.TP
.BI \-F " dir"
Prepend directory
.IR dir /dev name
to the search path for font, and device description files;

is the name of the device, usually
.BR pdf .
.
.
.TP
.BI \-I\~ dir
Search the directory

.
.B \-I
may be specified more than once;
each
.I dir
is searched in the given order.
.
To search the current working directory before others,
add
.RB \[lq] "\-I .\&" \[rq]
at the desired place;
it is otherwise searched last.

.TP
.B \-l
Orient the document in landscape format.
.
.
.TP
.BI \-p " paper-format"
Set the physical dimensions of the output medium.
.
This overrides the
.BR papersize ,
.BR paperlength ,

it accepts the same arguments as the
.B papersize
directive.
.
See
.MR groff_font 5

.SH Usage
.\" ====================================================================
.
.IR gropdf 's
input must be in the format produced by
.MR \%troff 1
and described in
.MR groff_out 5 .
.
Further,
its device and font description files must meet certain requirements.
.
The device
.B resolution
must be an integer multiple of\~72 times
.BR sizescale .
.
By default,
.I gropdf
uses a
.B resolution
of 72000 and a
.B sizescale
of 1000.
.
A valid paper format is mandatory;
see
.MR groff_font 5 .
.
While the PDF standard allows several font file formats
(like TrueType),
at present
.I gropdf
accepts only the same Type\~1 Adobe PostScript format as
.MR grops 1 .
.
Fewer Type\~1 fonts are supported natively in PDF documents than the
standard 35 fonts supported by
.I grops
and PostScript printers, \" XXX: strictly, PostScript Level 2, right?
but all are available since
.I gropdf
automatically embeds any that aren't specified by the PDF standard.
.
.
.P
.I gropdf
supports
.I foundries
that permit multiple providers to supply the same
.I groff
font names.
.
.IR groff 's
compilation process
attempts to locate Type\~1 fonts on the system,
populates a
.I Foundry
file with their locations,
and generates font description files corresponding to them.
.
Font description files can also be added after installation.
Each such file must contain a directive
.RS
.BI internalname\  psname
.RE
that maps the
.I groff
font name
(such as \[lq]TR\[rq])
to a PostScript name
(such as \[lq]Times\-Roman\[rq]).
.
Lines starting with
.B #
and blank lines are ignored.
.
The code for each character given in the font file must correspond
to the code in the default encoding for the font.
.
This code can be used with the
.B \[rs]N
escape sequence in
.I \%troff
to select the character
even if it lacks a special character name.
.
Every character in the font description must exist in the font file,
and the widths given in the description must match those used in the
font file.
.
See
.MR groff_font 5 .

.\" .LP
.\" Note that
.\" .B grops
.\" is able to display all glyphs in a PostScript font, not only 256.
.\" .I enc_file

.\" produces on the fly.
.
.
.P
.I gropdf
can automatically
.I embed
any downloadable fonts necessary to print the document.
.
Any fonts thus required must be listed in the file
.IR /usr/\:\%share/\:\%groff/\:\%1.24.1/\:\%font/\:\%devpdf/\:\%download ,
which should comprise lines of the form
.
.RS
.I "foundry font file-name"
.RE
.
where
.I foundry
is the foundry name, or blank for the default foundry;
.I font
is the PostScript name of the font,
and
.I file-name
is the name of the PFA or PFB font file,
and can be a pathname
(can contain slashes).
.
Any lines beginning with
.B #
and blank lines are ignored;
fields must be separated by tabs
(spaces are
.B not
allowed);
if
.I file-name
is not a pathname,
it is sought using the same mechanism as that used for
font metric files.
.\" XXX: This may be underspecified; do we mean groff font description
.\" files, or AFM files?  Also, gropdf does its own path searches rather
.\" than the stuff in libgroff so I'm not sure what "the same mechanism"
.\" means.  --GBR
.
The
.I download
file itself is also sought using this mechanism.
.
Foundry names are usually a single character
(such as \[oq]U\[cq] for the URW foundry)
or empty for the default foundry.
.
This default uses the same fonts as
.I Ghostscript
uses when it embeds fonts in a PDF file.
.
.

The default stroke and fill colors are black.

Special fonts include
.BR S ,
the PostScript Symbol font;
.BR SS ,
a subset of
.B S
with slanted lowercase Greek letters;
.BR EURO ,
which offers a Euro glyph
in several styles
for use with old devices lacking it;
and
.BR ZD ,
Zapf Dingbats.
.
In contrast to
.IR grops ,
.I gropdf
does not require a reversed variant of it
.RB ( ZDR );
the \[lq]hand pointing left\[rq] glyph
.RB ( \[rs][lh] )
is available nevertheless,
since
.I \%pdf.tmac
defines it using the
.B \[rs]X\[aq]pdf: xrev\[aq]
device extension command
(see below).
.
Some glyphs in these fonts are unnamed and must be accessed
as indexed characters,
using the
.B \[rs]N
escape sequence.
.
.P
The fonts corresponding to
.B EURO
and
.B SS
are unknown to the PDF standard;
.I groff
therefore provides their AFM files
(font metrics)
and PFA or PFB files
so that they can be used with other software
and embedded in PDF output.
.
.
.\" ====================================================================
. SS "Feature service levels and URW font support"
.\" ====================================================================
.
The traditional PostScript Type\~1 fonts
are limited in their glyph repertoire,
and the original versions from the Adobe foundry
are not free software.
.
Historically,
because their presence was mandated by the PostScript standard,
one could expect to find support for them in any conforming device
or software PostScript renderer.
.
PostScript
(\[lq]Level 1\[rq])
initially standardized 14 typefaces:
Times,
Helvetica,
and
Courier
each in four styles
(which
.I groff
groups into \[lq]families\[rq]);
a symbol font;
and a dingbats font.
.
PostScript Level 2 increased the number to 35,
adding the families
Avant Garde,
Bookman,
Helvetica Narrow,
New Century Schoolbook,
and
Palatino;
and a text font in one style,
Zapf Chancery medium italic.
.
A document could be small
because it did not need to embed font resources
unless it had unusual
(for the time)
glyph or typeface requirements.
.
This situation carried over into the early years
of PostScript's successor page description language,
PDF.
.
Nowadays,
it is common
to embed fonts in PDFs,
and authorities widely recommend this practice,
which increases the reliability of document rendering,
and many free software fonts are available
with much greater glyph coverage
than Adobe's Type\~1 fonts for PostScript.
.
.
.P
.I \%gropdf
attempts to work in variety of scenarios,
and delivers better results
when configured with supporting digital font files
(for embedding)
and font metrics files describing those fonts to the formatter.
.
.
.IP \[bu] 3n
.I "Full service"
is available
when
.I \%gropdf
can locate all 35 fonts of the PostScript Level 2 standard
on the file system
along with their corresponding font metrics (AFM) files.
.
The Adobe-compatible unnamed (default) foundry
supports up to 256 glyphs in each typeface.
.
Fonts from the URW foundry
(\[lq]U\[rq])
are compatible extensions of the Adobe fonts
with extended glyph coverage,
including support for Cyrillic script.
.
.IR groff 's
build process uses
.MR afmtodit 1
to generate font description files
from the URW foundry's AFM files;
see section \[lq]Files\[rq] below.
.
.
.IP \[bu]
.I "Intermediate service"
is available
when
.I \%gropdf
can locate all 35 fonts of the PostScript Level 2 standard
but not their corresponding font metrics (AFM) files.
.
.IR groff 's
build process copies the font description files
from those for the
.MR grops 1
driver,
reusing them for
.IR \%gropdf ;
this reduces glyph coverage to 256 glyphs maximum from each face,
and the \[lq]U\[rq] foundry is unavailable.
.
.
.IP \[bu]
.I "Basic service"
results when
.I \%gropdf
cannot locate all 35 fonts of the PostScript Level 2 standard.
.
Only the base 14 fonts of the PDF standard are available,
and only in the sense that the formatter can use their metrics
(copied from
.MR grops
font descriptions
as described above).
.
Use of the
.B \-e
option
to embed fonts in the generated PDF results in an error.

The following have counterpart

that take the same arguments and behave equivalently.

.TQ
.B "\eX\[aq]pdf: background off\[aq]"
.TQ
.BI "\eX\[aq]pdf: background footnote " bottom \[aq]
Produce a background rectangle on the page.
.
.
.RS
.TP 8n \" "bottom" + 2n
.I cmd
is the command,
which can be any of
.RB \[lq] page | fill | box \[rq]
in combination.
.
Thus,
.RB \[lq] pagefill \[rq]
would draw a rectangle which covers the whole current page size
(in which case the rest of the parameters can be omitted because the box
dimensions are taken from the current media size).
.
.RB \[lq] boxfill \[rq],
on the other hand,
requires the given dimensions to place the box.
.
Including
.RB \[lq] fill \[rq]
in the command paints the rectangle with the current fill colour
(as with
.BR \[rs]M[] )
and including
.RB \[lq] box \[rq]
gives the rectangle a border in the current stroke colour
(as with
.BR \[rs]m[] ).
.
.
.IP
.I cmd
may also be
.RB \[lq] off \[rq]
on its own,
which terminates drawing the current box.
.
If you have specified a page colour with
.RB \[lq] pagefill \[rq],
it is always the first box in the stack,
and if you specify it again,
it replaces the first entry.
.
Be aware that the
.RB \[lq]  pagefill \[rq]
box renders the page opaque,
so tools that \[lq]watermark\[rq] PDF pages are unlikely to be
successful.
.
To return the background to transparent,
issue an
.RB \[lq] off \[rq]
command with no other boxes open.
.
.
.IP
Finally,
.I cmd
may be
.RB \[lq] footnote \[rq]
followed by a new value for
.IR bottom ,
which is used for all open boxes on the current page.
This is to allow room for footnote areas that grow while a page is
processed
(to accommodate multiple footnotes,
for instance).
.
(If the value is negative,
it is used as an offset from the bottom of the page.)
.
.
.TP
.I left
.TQ
.I top
.TQ
.I right
.TQ
.I bottom
are the coordinates of the box.
.
The
.I top
and
.I bottom
coordinates are the minimum and maximum for the box,
since the actual start of the box is
.IR groff 's
drawing position when you issue the command,
and the bottom of the box is the point where you turn the box
.RB \[lq] off \[rq].
.
The top and bottom coordinates are used only if the box drawing extends
onto the next page;
ordinarily,
they would be set to the header and footer margins.
.
.
.TP
.I weight
provides the line width for the border if
.RB \[lq] box \[rq]
is included in the command.

Control the page numbering shown in a PDF reader's outline
(which also contains bookmarks).
.
Normally,
the page number associated with each bookmark is its sequence number in
the file,
but this might not match the desired numbering scheme.
.
A document may bear a cover sheet
(which has no page number);
front matter
(possibly including a table of contents)
that uses lowercase roman numerals;
the main matter,
which uses arabic numerals;
and back matter,
which may include appendices that are each prefixed with a letter and
independently numbered.
.
Place this command prior to breaking the page to which the new numbering
scheme is to apply.
.
It then persists until changed again.
.

If you have a font family which provides regular upright (roman),

(where \[lq]italic\[rq] may be \[lq]oblique\[rq] or \[lq]slanted\[rq]),
we recommend using

and
.BR BI ,
respectively,
as suffixes to the
.I groff
font family name to enable
.IR groff 's
font family and style selection features.
.
An example is
.IR groff 's
built-in support for Times:
the font family
name is abbreviated as
.BR T ,
and the
.I groff
font names are therefore
.BR TR ,
.BR TB ,
