gropdf(1) General Commands Manual gropdf(1) Name gropdf - groff output driver for Portable Document Format Synopsis gropdf [-delsW] [{-f|--format-options} bit-vector] [-F font-directory] [-I inclusion-directory] [-p paper-format] [--pdfver {1.4|1.7}] [-u [cmap-file]] [-y foundry] [file ...] gropdf --help gropdf -v gropdf --version Description The GNU roff PDF output driver translates the output of troff(1) into Portable Document Format. Normally, gropdf is invoked by groff(1) when the latter is given the "-T pdf" option. (In this installation, ps is the de- fault output device.) Use groff's -P option to pass any options shown above to gropdf. If no file arguments are given, or if file is "-", gropdf reads the standard input stream. It writes to the standard output stream. See section "Font installation" below for a guide to installing fonts for gropdf. Options --help displays a usage message, while -v and --version show version infor- mation; all exit afterward. -d Include debug information as comments within the PDF. Also pro- duces an uncompressed PDF. -e Forces gropdf to embed all fonts (even the 14 base PDF fonts). --format-options bit-vector -f bit-vector Specify advanced options for gropdf. Familiarity with the ISO 32000 PDF standard is helpful. The bit-vector argument is an integer that configures characteristics of the generated PDF. Add the following values to combine them. Value Meaning ------------------------------------------------------------ 1 Subset included Type 1 fonts. 2 Use more compact format for text by including space as a character. Fonts that do not include space as a glyph may conflict with this feature. 4 Compress all data streams. 8 Don't embed font files. (A font required by the document is not embedded; usually not useful.) The default feature combination is 7. To mimic what gropdf from groff 1.23 produced, specify "6" to turn off subsetting. -F dir Prepend directory dir/devname to the search path for font, and de- vice description files; name is the name of the device, usually pdf. -I dir Search the directory dir for files named in \X'pdf: pdfpic' device extension commands. -I may be specified more than once; each dir is searched in the given order. To search the current working di- rectory before others, add "-I ." at the desired place; it is oth- erwise searched last. -l Orient the document in landscape format. -p paper-format Set the physical dimensions of the output medium. This overrides the papersize, paperlength, and paperwidth directives in the DESC file; it accepts the same arguments as the papersize directive. See groff_font(5) for details. --pdfver {1.4|1.7} PDF version 1.7 introduced a more compact object format; this is now the default. If you require the original format (as produced by gropdf 1.23) set the version to 1.4. -s Append a comment line to end of PDF showing statistics, i.e. number of pages in document. Ghostscript's ps2pdf complains about this line if it is included, but works anyway. -u [cmap-file] gropdf normally includes a ToUnicode CMap with any font created us- ing text.enc as the encoding file, this makes it easier to search for words which contain ligatures. You can include your own CMap by specifying a cmap-file or have no CMap at all by omitting the argument. -W Exit with failure status if any warnings are issued. -y foundry Set the foundry to use for selecting fonts of the same name. Usage gropdf's input must be in the format produced by troff(1) and described in groff_out(5). Further, its device and font description files must meet certain requirements. The device resolution must be an integer multiple of 72 times sizescale. By default, gropdf uses a resolution of 72000 and a sizescale of 1000. A valid paper format is mandatory; see groff_font(5). While the PDF standard allows several font file formats (like TrueType), at present gropdf accepts only the same Type 1 Adobe PostScript format as grops(1). Fewer Type 1 fonts are supported natively in PDF documents than the standard 35 fonts supported by grops and PostScript printers, but all are available since gropdf automatically embeds any that aren't specified by the PDF standard. gropdf supports foundries that permit multiple providers to supply the same groff font names. groff's compilation process attempts to locate Type 1 fonts on the system, populates a 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 internalname psname that maps the groff font name (such as "TR") to a PostScript name (such as "Times-Roman"). Lines starting with # 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 \N escape sequence in 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 groff_font(5). gropdf can automatically embed any downloadable fonts necessary to print the document. Any fonts thus required must be listed in the file /usr/ local/share/groff/font/devpdf/download, which should comprise lines of the form foundry font file-name where foundry is the foundry name, or blank for the default foundry; font is the PostScript name of the font, and file-name is the name of the PFA or PFB font file, and can be a pathname (can contain slashes). Any lines be- ginning with # and blank lines are ignored; fields must be separated by tabs (spaces are not allowed); if file-name is not a pathname, it is sought using the same mechanism as that used for font metric files. The download file itself is also sought using this mechanism. Foundry names are usually a single character (such as `U' for the URW foundry) or empty for the de- fault foundry. This default uses the same fonts as Ghostscript uses when it embeds fonts in a PDF file. The default stroke and fill colors are black. Typefaces Styles called R, I, B, and BI mounted at font positions 1 to 4. Text fonts are grouped into families A, BM, C, H, HN, N, P, and T, each having members in each of these styles. AR AvantGarde-Book AI AvantGarde-BookOblique AB AvantGarde-Demi ABI AvantGarde-DemiOblique BMR Bookman-Light BMI Bookman-LightItalic BMB Bookman-Demi BMBI Bookman-DemiItalic CR Courier CI Courier-Oblique CB Courier-Bold CBI Courier-BoldOblique HR Helvetica HI Helvetica-Oblique HB Helvetica-Bold HBI Helvetica-BoldOblique HNR Helvetica-Narrow HNI Helvetica-Narrow-Oblique HNB Helvetica-Narrow-Bold HNBI Helvetica-Narrow-BoldOblique NR NewCenturySchlbk-Roman NI NewCenturySchlbk-Italic NB NewCenturySchlbk-Bold NBI NewCenturySchlbk-BoldItalic PR Palatino-Roman PI Palatino-Italic PB Palatino-Bold PBI Palatino-BoldItalic TR Times-Roman TI Times-Italic TB Times-Bold TBI Times-BoldItalic Another text font is not a member of a family. ZCMI ZapfChancery-MediumItalic Special fonts include S, the PostScript Symbol font; SS, a subset of S with slanted lowercase Greek letters; EURO, which offers a Euro glyph in several styles for use with old devices lacking it; and ZD, Zapf Dingbats. In con- trast to grops, gropdf does not require a reversed variant of it (ZDR); the "hand pointing left" glyph (\[lh]) is available nevertheless, since pdf.tmac defines it using the \X'pdf: xrev' device extension command (see below). Some glyphs in these fonts are unnamed and must be accessed as in- dexed characters, using the \N escape sequence. The fonts corresponding to EURO and SS are unknown to the PDF standard; 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 out- put. Feature service levels and URW font support The traditional PostScript Type 1 fonts are limited in their glyph reper- toire, and the original versions from the Adobe foundry are not free soft- ware. Historically, because their presence was mandated by the PostScript standard, one could expect to find support for them in any conforming de- vice or software PostScript renderer. PostScript ("Level 1") initially standardized 14 typefaces: Times, Helvetica, and Courier each in four styles (which groff groups into "families"); 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 un- less 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 relia- bility of document rendering, and many free software fonts are available with much greater glyph coverage than Adobe's Type 1 fonts for PostScript. gropdf attempts to work in variety of scenarios, and delivers better re- sults when configured with supporting digital font files (for embedding) and font metrics files describing those fonts to the formatter. * Full service is available when gropdf can locate all 35 fonts of the PostScript Level 2 standard on the file system along with their corre- sponding font metrics (AFM) files. The Adobe-compatible unnamed (de- fault) foundry supports up to 256 glyphs in each typeface. Fonts from the URW foundry ("U") are compatible extensions of the Adobe fonts with extended glyph coverage, including support for Cyrillic script. groff's build process uses afmtodit(1) to generate font description files from the URW foundry's AFM files; see section "Files" below. * Intermediate service is available when gropdf can locate all 35 fonts of the PostScript Level 2 standard but not their corresponding font metrics (AFM) files. groff's build process copies the font description files from those for the grops(1) driver, reusing them for gropdf; this re- duces glyph coverage to 256 glyphs maximum from each face, and the "U" foundry is unavailable. * Basic service results when 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 grops font descriptions as described above). Use of the -e option to embed fonts in the generated PDF results in an er- ror. Device extension commands gropdf supports many device extensions, accessed with the groff request device or roff \X escape sequence. First, it understands many of the de- vice extensions supported by grops(1). \X'ps: invis' Suppress output. \X'ps: endinvis' Stop suppressing output. \X'ps: exec gsave currentpoint 2 copy translate n rotate neg exch neg exch translate' where n is the angle of rotation. This is to support the align com- mand in pic(1). \X'ps: exec grestore' Used by pic(1) to restore state after rotation. \X'ps: exec n setlinejoin' where n can be one of the following values. 0 = Miter join 1 = Round join 2 = Bevel join \X'ps: exec n setlinecap' where n can be one of the following values. 0 = Butt cap 1 = Round cap, and 2 = Projecting square cap gropdf also supports a subset of the commands introduced in gpresent's present.tmac. PAUSE BLOCKS BLOCKE These allow you to create presentation PDFs. Many of the other commands are already available in other macro packages. These commands are implemented with groff X commands:- \X'ps: exec %%%%PAUSE' The section before this is treated as a block and is introduced us- ing the current BLOCK transition setting (see "\X'pdf: transition'" below). Equivalently, .pdfpause is available as a macro. \X'ps: exec %%%%BEGINONCE' Any text following this command (up to %%%%ENDONCE) is shown only once, the next %%%%PAUSE will remove it. If producing a non-presen- tation PDF, i.e. ignoring the pauses, see GROPDF_NOSLIDE below, this text is ignored. \X'ps: exec %%%%ENDONCE' This terminates the block defined by %%%%BEGINONCE. This pair of commands is what implements the .BLOCKS Once/.BLOCKE commands in present.tmac. The mom macro package already integrates these extensions, so you can build slides with mom. If you use present.tmac with gropdf there is no need to run the program presentps(1) since the output will already be a presentation PDF. All other ps: tags are silently ignored. gropdf also recognizes a device extension used by the DVI driver. \X'papersize=width,length' Set the page dimensions in centimeters to width by length. If the -l option was specified, these dimensions are swapped. Changes to the paper dimensions should occur prior to the first page, or during page ejection before starting a subsequent one. Caution: the ordering of dimensions differs from that used by paper- size.tmac and troff(1)'s "-d paper" option. \X'pdf: markstart /ANN-definition' \X'pdf: markend' Macros that support PDF features use these extension commands inter- nally to bracket hotspot text (a hyperlink). User documents should call the .pdfhref macro instead. Their application is found in other macro packages (like groff_man(7) or groff_mdoc(7)) that call .pdfhref with a -S argument, then indicate the end of hotspot text with \X'pdf: markend'\m[\*[pdf:curcol]]. \X'pdf: xrev' Toggle the reversal of glyph direction. This feature works by re- versing all following text. Each separate letter is also mirrored. One application is the reversal of glyphs in the Zapf Dingbats font. To restore the normal glyph orientation, repeat the command. gropdf supports several more device extensions using the pdf: tag. The following have counterpart convenience macros that take the same arguments and behave equivalently. .pdfbackground cmd left top right bottom weight .pdfbackground off .pdfbackground footnote bottom \X'pdf: background cmd left top right bottom weight' \X'pdf: background off' \X'pdf: background footnote bottom' Produce a background rectangle on the page. cmd is the command, which can be any of "page|fill|box" in com- bination. Thus, "pagefill" 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). "boxfill", on the other hand, requires the given dimensions to place the box. Including "fill" in the command paints the rectangle with the current fill colour (as with \M[]) and including "box" gives the rectangle a border in the current stroke colour (as with \m[]). cmd may also be "off" on its own, which terminates drawing the current box. If you have specified a page colour with "pagefill", it is always the first box in the stack, and if you specify it again, it replaces the first entry. Be aware that the "pagefill" box renders the page opaque, so tools that "watermark" PDF pages are unlikely to be successful. To return the background to transparent, issue an "off" com- mand with no other boxes open. Finally, cmd may be "footnote" followed by a new value for 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 foot- notes, for instance). (If the value is negative, it is used as an offset from the bottom of the page.) left top right bottom are the coordinates of the box. The top and bottom coordi- nates are the minimum and maximum for the box, since the ac- tual start of the box is groff's drawing position when you issue the command, and the bottom of the box is the point where you turn the box "off". The top and bottom coordi- nates are used only if the box drawing extends onto the next page; ordinarily, they would be set to the header and footer margins. weight provides the line width for the border if "box" is included in the command. An sboxes macro file is also available; see groff_tmac(5). .pdfmarksuspend .pdfmarkrestart \X'pdf: marksuspend' \X'pdf: markrestart' If you use a page location trap to produce a header or footer, or otherwise interrupt a document's text, you need to use these com- mands if a PDF hotspot crosses a trap boundary; otherwise any text output by the trap will be marked as part of the hotspot. To pre- vent this error, place these device extension escape sequences or their corresponding convenience macros .pdfmarksuspend and .pdfmarkrestart at the start and end of the trap macro, respec- tively. .pdfpagename name \X'pdf: pagename name' Assign the current page a name. All documents bear two default names, `top' and `bottom'. .pdfpagenumbering type prefix start \X'pdf: pagenumbering type prefix start' 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 mat- ter, 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. type specifies the numbering system to use. It should be one of "Decimal", "Roman", "roman", "Alpha", or "alpha". This pa- rameter may be abbreviated to the first letter, whose let- tercase determines that used for the numbers where applica- ble. The ordering used by the alphabetic numbering systems is A-Z ... AA-AZ ... ZA-ZZ. type can also be ".", which se- lects no numbering system; you may still provide a prefix. prefix specifies text to precede the page number. For example, to number the pages of an appendix "A-1", "A-2", and so forth, use a prefix of "A-" and a type of "Decimal". start determines the page number. It defaults to 1. .pdfpic file alignment width height line-length \X'pdf: pdfpic file alignment width height line-length' Place an image from file file of desired width and height (if height is missing or zero then it is scaled proportionally). If alignment is -L the drawing is left-aligned. If it is -C or -R a line-length greater than the width of the drawing is required as well. If width is specified as zero then the width is scaled in proportion to the height. If both width and height are non-zero the image is scaled to `best fit'. The availability of other software on the system, such as PerlMag- ick, influences the types of image files gropdf can embed in its output. +-------+------+---------+-------------+--------------------+ | | none | file(1) | identify(1) | Image::Magick(3pm) | +-------+------+---------+-------------+--------------------+ | .pdf | / | / | / | / | +-------+------+---------+-------------+--------------------+ | .jpg | X | / | / | / | +-------+------+---------+-------------+--------------------+ | .jp2 | X | X | / | / | +-------+------+---------+-------------+--------------------+ | other | X | X | X | / | +-------+------+---------+-------------+--------------------+ See groff_tmac(5) for a description of the PDFPIC macro, which pro- vides a convenient high-level interface for inclusion of various graphic file formats. .pdfswitchtopage when name \X'pdf: switchtopage when name' Normally each new page is appended to the end of the document, this command allows following pages to be inserted at a `named' position within the document (see pagename command above). `when' can be ei- ther `after' or `before'. If it is omitted it defaults to `before'. It should be used at the end of the page before you want the switch to happen. This allows pages such as a TOC to be moved to elsewhere in the document, but more esoteric uses are possible. .pdftransition scope mode duration dimension motion direction scale bool \X'pdf: transition scope mode duration dimension motion direction scale bool' Configure the style of page transitions, as used in "slides" (or "foils"). scope can be either SLIDE or BLOCK. SLIDE applies the transition when a new slide is introduced to the screen; BLOCK ap- plies it to the individual blocks making up the slide. mode is the transition type between slides:- Split - Two lines sweep across the screen, revealing the new page. The lines may be either horizontal or vertical and may move inward from the edges of the page or outward from the center, as specified by the dimension and motion entries, re- spectively. Blinds - Multiple lines, evenly spaced across the screen, synchronously sweep in the same direction to reveal the new page. The lines may be either horizontal or vertical, as specified by the dimension entry. Horizontal lines move downward; vertical lines move to the right. Box - A rectangular box sweeps inward from the edges of the page or outward from the center, as specified by the motion entry, revealing the new page. Wipe - A single line sweeps across the screen from one edge to the other in the direction specified by the direction en- try, revealing the new page. Dissolve - The old page dissolves gradually to reveal the new one. Glitter - As Dissolve, except that the effect sweeps across the page in a wide band moving from one side of the screen to the other in the direction specified by the direction entry. R - The new page simply replaces the old one with no special transition effect; the direction entry shall be ignored. Fly - (PDF 1.5) Changes are flown out or in (as specified by motion), in the direction specified by direction, to or from a location that is offscreen except when direction is None. Push - (PDF 1.5) The old page slides off the screen while the new page slides in, pushing the old page out in the direction specified by direction. Cover - (PDF 1.5) The new page slides on to the screen in the direction specified by direction, covering the old page. Uncover - (PDF 1.5) The old page slides off the screen in the direction specified by direction, uncovering the new page in the direction specified by direction. Fade - (PDF 1.5) The new page gradually becomes visible through the old one. duration is the length of the transition in seconds (default 1). dimension (Optional; Split and Blinds transition styles only) The dimension in which the specified transition effect shall occur: H Horizontal, or V Vertical. motion (Optional; Split, Box and Fly transition styles only) The di- rection of motion for the specified transition effect: I Inward from the edges of the page, or O Outward from the center of the page. direction (Optional; Wipe, Glitter, Fly, Cover, Uncover and Push transition styles only) The direction in which the specified transi- tion effect shall moves, expressed in degrees counterclockwise starting from a left-to-right direction. If the value is a number, it shall be one of: 0 = Left to right, 90 = Bottom to top (Wipe only), 180 = Right to left (Wipe only), 270 = Top to bottom, 315 = Top-left to bottom-right (Glitter only) The value can be None, which is relevant only for the Fly transition when the value of scale is not 1.0. scale (Optional; PDF 1.5; Fly transition style only) The starting or ending scale at which the changes shall be drawn. If motion speci- fies an inward transition, the scale of the changes drawn shall progress from scale to 1.0 over the course of the transition. If motion specifies an outward transition, the scale of the changes drawn shall progress from 1.0 to scale over the course of the tran- sition bool (Optional; PDF 1.5; Fly transition style only) If true, the area that shall be flown in is rectangular and opaque. Any of the parameters may be replaced with a "." which signifies the parameter retains its previous value, also any trailing missing pa- rameters are ignored. Note: not all PDF Readers support any or all these transitions. Macros gropdf's support macros in pdf.tmac define the convenience macros described above. Some features have no direct device extension escape sequence coun- terpart. .pdfbookmark [-T tag-name] level text Mark the nearest page location as a bookmark, and optionally a named destination as well. Bookmarks populate the outline pane of the reader. They are organized into a hierarchical tree; each level of the tree is numbered, starting at 1, and named as text in the out- line. Named destinations permit hyperlink-style navigation within the document. Specifying -T followed by tag-name creates a named destination making the page location eligible as a target named by ".pdfhref L ...". .pdfhref L -D dest [-S] [-P prefix-text] [-A suffix-text] [link-text] Create a hotspot link to dest, (the tag-name) which a ".pdfbook- mark ..." or ".pdfhref M ..." call elsewhere in the document should define. (If the document employs forward references, it must be processed twice; see pdfmom(1).) If link-text is omitted the text associated with dest, when it was created, is formatted as the link text. The -P and -A arguments format their successors as text be- fore and after the link text, respectively, without intervening space. Specifying -S prevents pdfhref from "closing" the hotspot, requiring the document (or macro package wrapping pdfhref) to do so itself with "\X'pdf: markend'\m[\*[pdf:curcol]]". .pdfhref M [-E] [-N tag-name] dest Mark the nearest page location as a destination named (the first word of) dest, which should be unique within a document. Specifying -T followed by tag-name overrides this default. Specifying -E for- mats dest as text in the document as well. .pdfhref W -D uri [-S] [-P prefix-text] [-A suffix-text] link-text Create a hotspot link to uri, a World Wide Web Universal Resource Identifier (URI). The -P and -A arguments format their successors as text before and after the link text, respectively, without inter- vening space. Specifying -S prevents pdfhref from "closing" the hotspot, requiring the document (or macro package wrapping pdfhref) to do so itself with "\X'pdf: markend'\m[\*[pdf:curcol]]". .pdfinfo /field content ... Define PDF metadata. field may be one of Title, Author, Subject, Keywords, or another datum supported by the PDF standard or your reader. field must be prefixed with a slash. .pdfnote [-T title] text Create an annotation in the document. Reader support for this fea- ture varies. Some place an icon at the current position on the page; hovering over the icon reveals any title, while clicking on the icon pops up a window containing text. Parameters The following parameters, shown as roff control lines, affect the operation of gropdf. +-------------------------------------------------------------------------+ | Parameter Purpose Default | +-------------------------------------------------------------------------+ | .nr PDFNOTE.WIDTH Set width of annotation 1c | | icon. | | .nr PDFNOTE.HEIGHT Set height of annotation 1c | | icon. | | .ds PDFNOTE.COLOR Set RGB color of annotation 1.00 1.00 0.00 | | icon (RGB) | | .ds PDFNOTE.OPACITY Set opacity of annotation 0.6 | | icon (decimal value in [0, | | 1]). | | .nr PDFOUTLINE.FOLDLEVEL Set depth of visible book- 10000 | | mark hierarchy. | | .nr PDFHREF.VIEW.LEADING Set position adjustment 5p | | when clicking bookmark or | | internal hotspot. | | .nr PDFHREF.LEADING Configure size of increased 2.0p | | clickable area around a | | hotspot. | | .ds PDFHREF.BORDER Configure the border width 0 0 0 | | around a hotspot by speci- | | fying two zeroes followed | | by the desired width in | | points. Do not use a scal- | | ing unit. | | .ds PDFHREF.COLOR Set RGB color of link text. 0.00 0.35 0.60 | +-------------------------------------------------------------------------+ In the foregoing, you can also spell "COLOR" in string names as "COLOUR". Importing PDF graphics If you are importing an image as a PDF file, it must be a single page and the drawing must just fit inside the media size of the PDF file. In inkscape(1) or gimp(1), for example, make sure the canvas size just fits the image. The PDF parser gropdf implements has not been rigorously tested with all applications that produce PDF. If you find a single-page PDF which fails to import properly, try processing it with the pdftk(1) program. pdftk existing-file output new-file You may find that new-file imports successfully. TrueType and other font formats gropdf does not yet support any font formats besides Adobe Type 1 (PFA or PFB). Font installation For your convenience, groff offers install-font.bash, a shell script that interactively assists the configuration of fonts for use with the GNU troff formatter and the gropdf output driver. See section "Files" below. The following is a step-by-step font installation guide for gropdf. * Convert your font to something groff understands. This is a PostScript Type 1 font in PFA or PFB format, together with an AFM file. A PFA file begins as follows. %!PS-AdobeFont-1.0: A PFB file contains this string as well, preceded by some non-printing bytes. In the following steps, we will consider the use of CTAN's BrushScriptX-Italic font in PFA format. * Convert the AFM file to a groff font description file with the afmtodit(1) program. For instance, $ afmtodit BrushScriptX-Italic.afm text.map BSI converts the Adobe Font Metric file BrushScriptX-Italic.afm to the groff font description file BSI. If you have a font family which provides regular upright (roman), bold, italic, and bold-italic styles, (where "italic" may be "oblique" or "slanted"), we recommend using R, B, I, and BI, respectively, as suf- fixes to the groff font family name to enable groff's font family and style selection features. An example is groff's built-in support for Times: the font family name is abbreviated as T, and the groff font names are therefore TR, TB, TI, and TBI. In our example, however, the BrushScriptX font is available in a single style only, italic. * Install the groff font description file(s) in a devpdf subdirectory in the search path that groff uses for device and font file descriptions. See the GROFF_FONT_PATH entry in section "Environment" of troff(1) for the current value of the font search path. While groff doesn't directly use AFM files, it is a good idea to store them alongside its font de- scription files. * Register fonts in the devpdf/download file so they can be located for embedding in PDF files gropdf generates. Only the first download file encountered in the font search path is read. If in doubt, copy the de- fault download file (see section "Files" below) to the first directory in the font search path and add your fonts there. The PostScript font name used by gropdf is stored in the internalname field in the groff font description file. (This name does not necessarily resemble the font's file name.) If the font in our example had originated from a foundry named Z, we would add the following line to download. Z->BrushScriptX-Italic->BrushScriptX-Italic.pfa A tab character, depicted as ->, separates the fields. The default foundry has no name: its field is empty and entries corresponding to it start with a tab character, as will the one in our example. * Test the selection and embedding of the new font. printf "\\f[BSI]Hello, world!\n" | groff -T pdf -P -e >hello.pdf see hello.pdf Exit status 0 gropdf successfully produced a PDF document. 1 gropdf experienced a critical error, or warnings were emitted and the -W option was specified. 2 gropdf could not interpret its command-line arguments. Environment GROFF_FONT_PATH A list of directories in which to seek the selected output device's directory of device and font description files. If, in the download file, the font file has been specified with a full path, no directo- ries are searched. See troff(1) and groff_font(5). GROPDF_NOSLIDE If set and evaluates to a true value (to Perl), gropdf ignores com- mands specific to presentation PDFs, producing a normal PDF instead. GROPDF_OPTIONS gropdf interprets the contents of this environment variable as a space-separated list of command-line options. Explicit command-line options override any settings from this environment variable. SOURCE_DATE_EPOCH A timestamp (expressed as seconds since the Unix epoch) to use as the output creation timestamp in place of the current time. The time is converted to human-readable form using Perl's gmtime() func- tion and recorded in a PDF comment. TZ The time zone to use when converting the current time to human-read- able form; see tzset(3). If SOURCE_DATE_EPOCH is used, it is always converted to human-readable form using UTC. Files /usr/local/share/groff/font/devpdf/DESC describes the pdf output device. /usr/local/share/groff/font/devpdf/F describes the font known as F on device pdf. /usr/local/share/groff/font/devpdf/U-F describes the font from the URW foundry (versus the Adobe default) known as F on device pdf. /usr/local/share/groff/font/devpdf/download lists fonts available for embedding within the PDF document (by analogy to the ps device's downloadable font support). /usr/local/share/groff/font/devpdf/Foundry is a data file used by the groff build system to locate PostScript Type 1 fonts. /usr/local/share/groff/font/devpdf/symbolsl.afm provides metrics for the slanted symbol font known to groff as SS. These data facilitate use of the font with non-groff software. /usr/local/share/groff/font/devpdf/symbolsl.pfb supplies the slanted symbol font known to groff as SS. /usr/local/share/groff/font/devpdf/enc/text.enc describes the encoding scheme used by most PostScript Type 1 fonts; the encoding directive of font description files for the pdf device refers to it. /usr/local/share/groff/font/devpdf/generate/symbolsl.sfd is the source form of the symbolsl.pfb font, in spline font database (SFD) format. /usr/local/share/groff/tmac/pdf.tmac defines macros for use with the pdf output device. It is automati- cally loaded by troffrc when the pdf output device is selected. /usr/local/share/groff/tmac/pdfpic.tmac defines the PDFPIC macro for embedding images in a document; see groff_tmac(5). It is automatically loaded by troffrc. /usr/local/share/doc/groff/examples/install-font.bash This script, contributed by mom macro package author Peter Schaffter and long available at his web site, assists with making TrueType (.ttf), OpenType (.otf), and PostScript Type 1 (.pfa, .pfb) fonts available to groff. Change to its directory and run "bash install-font.bash -H" for a man page-like description of its features and operation. Authors gropdf was written and is maintained by Deri James.
