       dvisvgm - converts DVI files to the XML-based SVG format


       dvisvgm [ options ] file [.dvi]

       dvisvgm -E [ options ] file [.eps]


       The command-line utility dvisvgm converts DVI files, as generated by TeX/LaTeX, to the
       XML-based scalable vector graphics format SVG. Since the current SVG standard 1.1 doesn’t
       specify multi-page graphics, dvisvgm creates separate SVG files for each DVI page. Because
       of compatibility reasons, only the first page is converted by default. In order to select
       a different page or arbitrary page sequences, use option -p which is described below.

       dvisvgm should properly convert all pages that are made up of fonts and rules only.
       However, the utility also supports a couple of DVI extensions defined in terms of DVI
       specials. For a more detailed overview, see section support of specials below.

       As SVG is a vector based graphics format, dvisvgm tries to convert the glyph outlines of
       all used fonts into scalable path descriptions. The fastest way to do that is to extract
       the path information from PFB (PostScript Type 1) files. So, if dvisvgm is able to find a
       PFB file for a required font, it will read the necessary information from this file.

       TeX’s main source for font descriptions is Metafont though, which produces bitmap output.
       That’s why not all obtainable TeX fonts are available in PFB format. In these cases,
       dvisvgm tries to vectorize Metafont’s output (GF fonts) by tracing the glyph bitmaps. The
       results are not as perfect as most (manually optimized) PFB outlines but are nonetheless
       really nice in most cases.


       -a, --trace-all=[retrace]
           This option forces dvisvgm to trace not only the actually needed glyphs but all glyphs
           of all bitmap fonts used in the DVI file. Since the tracing results are stored in the
           font cache, all following DVI conversions (without option --trace-all) where these
           fonts are involved, will be much faster. By default, dvisvgm traces only the actually
           needed glyphs, and adds them to the cache. The boolean option retrace determines how
           to handle glyphs already stored in the cache. By default, these glyphs are skipped.
           Setting argument retrace to yes or true forces dvisvgm to trace the corresponding
           bitmaps again.

               This option only takes affect if font caching is active. Thus, --trace-all cannot
               be combined with option --cache=none.

       -b, --bbox=fmt
           Sets the bounding box of the generated graphic to the specified format. The parameter
           fmt takes either one of the format specifiers listed below, or a sequence of four
           comma- or whitespace-separated length values x1, y1, x2 and y2. The latter define two
           diagonal corners of the bounding box. Each length value consists of a floating point
           number and an optional length unit (pt, bp, cm, mm, in, or pc). If the unit is
           omitted, TeX points (pt) are assumed.

           It’s also possible to give only one length value l. In this case, the minimal bounding
           box is computed and enlarged by adding (-l,-l) to the upper left and (l,l) to the
           lower right corner.

           Alternatively, the following format specifiers are supported:

           International DIN/ISO paper sizes
               An, Bn, Cn, Dn, where n is a non-negative integer, e.g. A4 or a4 for DIN/ISO A4
               format (210mm × 297mm).

           North American paper sizes
               invoice, executive, legal, letter, ledger

           Special bounding box sizes

               dvi    page size stored in the DVI file
               min    computes the minimal/tightest
                      bounding box
               none   no bounding box is assigned

       Page orientation
           The default page orientation for DIN/ISO and American paper sizes is portrait, i.e.
           width < height. Appending -landscape or simply -l to the format string switches to
           landscape mode (width > height). For symmetry reasons you can also explicitly add
           -portrait or -p to indicate the default portrait format. Note that these suffixes are
           part of the size string and not separate options. Thus, they must directly follow the
           size specifier without additional blanks. Furthermore, the orientation suffixes can’t
           be used with dvi, min, and none.

               Option -b, --bbox only affects the bounding box and does not transform the page
               content. Hence, if you choose a landscape format, the page won’t be rotated.

       -C, --cache[=dir]
           To speed up the conversion process of bitmap fonts, dvisvgm saves intermediate
           conversion information in cache files. By default, these files are stored in
           $HOME/.dvisvgm/cache. If you prefer a different location, use option --cache to
           overwrite the default. Furthermore, it is also possible to disable the font caching
           mechanism completely with option --cache=none. If argument dir is omitted, dvisvgm
           prints the path of the default cache directory and some information about the stored
           fonts. Additionally, outdated and corrupted cache files are removed.

           Enables colorization of messages printed during the conversion process. The colors can
           be customized via the environment variable DVISVGM_COLORS. See the ENVIRONMENT section
           below for further information.

       -E, --eps
           If this option is given, dvisvgm does not expect a DVI but an EPS input file, and
           tries to convert it to SVG. In order to do so, a single psfile special command is
           created and forwarded to the PostScript special handler. This option is only available
           if dvisvgm was built with PostScript support enabled, and requires Ghostscript to be
           available. See option --libgs for further information.

       -e, --exact
           If this option is given, dvisvgm computes the precise bounding box of each character.
           By default, the values stored in a font’s TFM file are used to determine a glyph’s
           extent. As these values are intended to realize optimal character placements and are
           not designed to represent the exact dimensions, they don’t necessarily correspond with
           the bounds of the visual glyphs. Thus, width and/or height of some glyphs may be
           larger than the respective TFM values. As a result, this can lead to clipped
           characters at the bounds of the SVG graphic. With option --exact, dvisvgm analyzes the
           actual shape of each character and derives a usually tight bounding box.

       -m, --fontmap=filenames
           Loads and evaluates a single or multiple font map files. These files are required to
           resolve font file names and encodings. dvisvgm does not provide its own map file but
           tries to read available ones coming with dvips or dvipdfm. If option --fonrmapm is not
           given, dvisvgm looks for the default map files,, and
           (in this order). Otherwise, the listed files are used. Multiple filenames must be
           separated by commas without leading and/or trailing whitespace. The map files are
           evaluated in the given order. By default, redefined mappings do not replace previous
           ones. However, each filename can be preceded by an optional mode specifier (+, -, or
           =) to change this behavior:

               Only those entries in the given map file that don’t redefine a font mapping are
               applied. That’s also the default mode if no mode specifier is given.

               Ensures that none of the font mappings defined in the given map file are used,
               i.e. previously defined mappings for the specified fonts are removed.

               All mappings defined in the map file are applied. Previously defined settings for
               the same font are replaced.

               If the first filename in the filename sequence is preceded by a mode specifier,
               dvisvgm loads the default font map (see above) and applies the other map files
               afterwards. Otherwise, none of default map files will be loaded automatically.

               Examples:, loads followed by
      where all redefinitions of are ignored.
     , loads the default map file followed by
      and where all redefinitions of replace
               previous entries. Afterwards, all definitions for the fonts given in
               are removed again.

               For further information about the map file formats, see the manuals of dvips and

       -h, --help[=mode]
           Prints a short summary of all available command-line options. The optional mode
           parameter is an integer value between 0 and 2. It selects the display variant of the
           help text. Mode 0 lists all options divided into categories with section headers. This
           is also the default if dvisvgm is called without parameters. Mode 1 lists all options
           ordered by the short option name, while mode 2 sorts the lines by the long option

           Disables the removal of temporary files as created by Metafont (usually .gf, .tfm, and
           .log files).

           This option is only available if the Ghostscript library is not directly linked to
           dvisvgm and if PostScript support was not completely disabled during compilation. In
           this case, dvisvgm tries to load the shared GS library dynamically during runtime. By
           default, it expects the library’s name to be (on Unix-like systems) or
           gsdll32.dll/gsdll64.dll (Windows). Option --libgs can be used to give a different
           name. Alternatively, it’s also possible to set the GS library name by the environment
           variable LIBGS. The latter has less precedence than the command-line option.

       -l, --list-specials
           Prints a list of registered special handlers and exits. Each handler processes a set
           of special statements belonging to the same category. In most cases, the categories
           are identified by the prefix of the special statements. It’s usually a leading word
           separated from the rest of the statement by a colon or a blank, e.g.  color or ps.

       -M, --mag=factor
           Sets the magnification factor applied in conjunction with Metafont calls prior tracing
           the glyphs. The larger this value, the better the tracing results. Nevertheless, large
           magnification values can cause Metafont arithmetic errors due to number overflows. So,
           use this option with care. The default setting usually produces nice results.

           Suppresses the generation of missing font files. If dvisvgm can’t find a font file
           through the kpathsea lookup mechanism, it calls the external tools mktextfm or mktexmf
           by. This option disables these calls.

       -n, --no-fonts[=variant]
           If this option is given, dvisvgm doesn’t create SVG font elements but uses paths
           instead. The resulting SVG files tends to be larger but concurrently more compatible
           with most applications that don’t support SVG fonts yet. The optional argument variant
           selects the method how to substitute fonts by paths. Variant 0 creates path and use
           elements. Variant 1 creates path elements only. Option --no-fonts implies --no-styles.

       -c, --scale=sx[,sy]
           Scales the page content horizontally by sx and vertically by sy. This option is
           equivalent to -TSsx,sy.

       -S, --no-specials[=names]
           Disable processing of special commands embedded in the DVI file. If no further
           parameter is given, all specials are ignored. To selectively disable sets of specials,
           an optional comma-separated list of names can be appended to this option. A name is
           the unique identifier referencing the intended special handler. Option --list-specials
           lists all currently available handlers and their names. All unsupported special
           statements are silently ignored.

           By default, dvisvgm creates CSS styles and class attributes to reference fonts because
           it’s more compact than repeatedly set the complete font information in each text
           element. However, if you prefer direct font references, the default behavior can be
           disabled with option --no-styles.

       -o, --output=pattern
           Sets the name pattern of the output file. Parameter pattern is a string that may
           contain the variables %f and %p.  %f stands for the base name of the DVI file, i.e.
           the DVI filename without suffix, and %p is the current page number. The default
           pattern is %f-%p.svg if the DVI file consists of more than one page, and %f.svg
           otherwise. That means, a DVI file foo.dvi is converted to foo.svg if foo.dvi is a
           single-page document. Otherwise, multiple SVG files foo-01.svg, foo-02.svg, etc. are
           produced. In Windows environments, the percent sign indicates dereferenced environment
           variables, and must therefore be protected by a second percent sign, e.g.

       -p, --page=ranges
           This option sets the pages to be processed. Parameter ranges consists of a
           comma-separated list of single page numbers and/or page ranges. A page range is a pair
           of numbers separated by a hyphen, e.g. 5-12. Thus, a page sequence might look like
           this: 2-4,6,9-12,15. It doesn’t matter if a page is given more than once or if page
           ranges overlap. dvisvgm always extracts the page numbers in ascending order and
           converts them only once. In order to stay compatible with previous versions, the
           default page sequence is 1. dvisvgm therefore converts only the first page and not the
           whole document in case option --page is omitted. Usually, page ranges consist of two
           numbers denoting the first and last page to be converted. If the conversion is to be
           started at page 1, or if it should continue up to the last DVI page, the first or
           second range number can be omitted, respectively. Example: --page=-10 converts all
           pages up to page 10, --page=10- converts all pages starting with page 10. Please
           consider that the page values don’t refer to the page numbers printed on the page.
           Instead, the physical page count is expected, where the first page always gets number

       -d, --precision=digits
           Specifies the maximal number of decimal places applied to floating-point attribute
           values. All attribute values written to the generated SVG file(s) are rounded
           accordingly. The parameter digits allows integer values from 0 to 6, where 0 enables
           the automatic selection of significant decimal places. This is also the default value
           if dvisvgm is called without option --precision.

       -P, --progress[=delay]
           Enables a simple progress indicator shown when time-consuming operations like
           PostScript specials are processed. The indicator doesn’t appear before the given delay
           (in seconds) has elapsed. The default delay value is 0.5 seconds.

       -r, --rotate=angle
           Rotates the page content clockwise by angle degrees around the page center. This
           option is equivalent to -TRangle.

       -s, --stdout
           Don’t write the SVG output to a file but redirect it to stdout.

       -T, --transform=commands
           Applies a sequence of transformations to the SVG content. Each transformation is
           described by a command beginning with a capital letter followed by a list of
           comma-separated parameters. Following transformation commands are supported:

           T tx[,ty]
               Translates (moves) the page in direction of vector (tx,ty). If ty is omitted, ty=0
               is assumed. The expected unit length of tx and ty are TeX points (1pt =
               1/72.27in). However, there are several constants defined to simplify the unit
               conversion (see below).

           S sx[,sy]
               Scales the page horizontally by sx and vertically by sy. If sy is omitted, sy=sx
               is assumed.

           R angle[,x,y]
               Rotates the page clockwise by angle degrees around point (x,y). If the optional
               arguments x and y are omitted, the page will be rotated around its center
               depending on the chosen page format. When option -bnone is given, the rotation
               center is origin (0,0).

           KX angle
               Skews the page along the x-axis by angle degrees. Argument angle can take any
               value except 90+180k, where k is an integer.

           KY angle
               Skews the page along the y-axis by angle degrees. Argument angle can take any
               value except 90+180k, where k is an integer.

           FH [y]
               Mirrors (flips) the page at the horizontal line through point (0,y). Omitting the
               optional argument leads to y=h/2, where h denotes the page height (see pre-defined
               constants below).

           FV [x]
               Mirrors (flips) the page at the vertical line through point (x,0). Omitting the
               optional argument leads to x=w/2, where w denotes the page width (see pre-defined
               constants below).

           M m1,...,m6
               Applies a transformation described by the 3×3 matrix
               ((m1,m2,m3),(m4,m5,m6),(0,0,1)), where the inner triples denote the rows.

                   All transformation commands of option -T, --transform are applied in the order
                   of their appearance. Multiple commands can optionally be separated by spaces.
                   In this case the whole transformation string has to be enclosed in double
                   quotes. All parameters are expressions of floating point type. You can either
                   give plain numbers or arithmetic terms combined by the operators + (addition),
                   - (subtraction), * (multiplication), / (division) or % (modulo) with common
                   associativity and precedence rules. Parentheses may be used as well.

                   Additionally, some pre-defined constants are provided:

                   ux   horizontal position of upper
                        left page corner in TeX point
                   uy   vertical position of upper left
                        page corner in TeX point units

                   h    page height in TeX point units
                        (0 in case of -bnone)
                   w    page width in TeX point units (0
                        in case of -bnone)

                   Furthermore, you can use the length constants pt, mm, cm and in, e.g.  2cm or
                   1.6in. Thus, option -TT1in,0R45 moves the page content 1 inch to the right and
                   rotates it by 45 degrees around the page center afterwards.

                   For single transformations you can also use options -c, -t and -r. Note that
                   the order in which these options are given is not significant, i.e. you can’t
                   use them to describe transformation sequences. They are simply independent
                   shorthand options for common transformations.

       -t, --translate=tx[,ty]
           Translates (moves) the page content in direction of vector (tx,ty). This option is
           equivalent to -TTtx,ty.

       -v, --verbosity=level
           Controls the type of messages printed during a dvisvgm run:

           0   no message output
           1   error messages only
           2   warning messages only
           4   informational messages only

               By adding these values you can combine the categories. The default level is 7,
               i.e. all messages are printed.

       -V, --version[=extended]
           Prints the version of dvisvgm and exits. If the optional argument is set to yes, the
           version numbers of the linked libraries are printed as well.

       -z, --zip[=level]
           Creates a compressed SVG file with suffix .svgz. The optional argument specifies the
           compression level. Valid values are in the range of 1 to 9 (default value is 9).
           Larger values cause better compression results but take more computation time.

               This option cannot be combined with -s, --stdout.


       dvisvgm supports several sets of special commands that can be used to enrich DVI files
       with additional features, like color, graphics or hyperlinks. The evaluation of special
       commands is delegated to various handlers. Each handler is responsible for all special
       statements of the same command set, i.e. commands beginning with the same prefix. To get a
       list of actually provided special handlers, use option --list-specials (see above).

           Special statement for changing the background/page color. Since SVG 1.1 doesn’t
           support background colors, dvisvgm inserts a rectangle of the chosen color into the
           generated SVG document. This rectangle always gets the same size as the selected or
           computed bounding box. This background color command is part of the color special set
           but is handled separately in order to let the user turn it off. For an overview of the
           command syntax, see the documentation of dvips, for instance.

           Statements of this command set provide instructions to change the text/paint color.
           For an overview of the exact syntax, see the documentation of dvips, for instance.

           dvisvgm offers its own small set of specials. The following list gives a brief

           dvisvgm:raw text
               Adds an arbitrary sequence of characters to the SVG output. dvisvgm does not
               perform any validation here, thus the user has to ensure that the resulting SVG is
               still valid. Parameter text may contain the macros {?x}, {?y}, and {?color} that
               are expanded to the current x or y coordinate and the current color, respectively.
               Also, macro {?nl} expands to a newline character.

           dvisvgm:img width height file
               Creates an image element at the current graphic position referencing the given
               file. JPEG, PNG, and SVG images can be used here. However, dvisvgm does not check
               the file format or the file name suffix. The lengths width and height must be
               given as plain floating point numbers in TeX point units (1in = 72.27pt).

           dvisvgm:bbox n[ew] name
               Defines or resets a local bounding box called name. The name may consist of
               letters and digits. While processing a DVI page, dvisvgm continuously updates the
               (global) bounding box of the current page in order to determine the minimal
               rectangle containing all visible page components (characters, images, drawing
               elements etc.) Additionally to the global bounding box, the user can request an
               arbitrary number of named local bounding boxes. Once defined, these boxes are
               updated together with the global bounding box starting with the first character
               that follows the definition. Thus, the local boxes can be used to compute the
               extent of parts of the page. This is useful for scenarios where the generated SVG
               file is post-processed. In conjunction with special dvisvgm:raw, the macro {?bbox
               name} expands to the four values x, y, w, and h (separated by spaces) specifying
               the coordinates of the upper left corner, width, and height of the local box name.
               If box name wasn’t previously defined, all four values equal zero.

           dvisvgm:bbox width height [depth]
               Updates the bounding box of the current page by embedding a virtual rectangle (x,
               y, width, height) where the lower left corner is located at the current DVI
               drawing position (x,y). If the optional parameter depth is specified, dvisvgm
               embeds a second rectangle (x, y, width, -depth). The lengths width, height and
               depth must be given as plain floating point numbers in TeX point units (1in =
               72.27pt). Depending on size and position of the virtual rectangle, this command
               either enlarges the overall bounding box or leaves it as is. It’s not possible to
               reduce its extent. This special should be used in conjunction with dvisvgm:raw in
               order to update the viewport of the page properly.

           dvisvgm:bbox a[bs] x1 y1 x2 y2
               This variant of the bbox special updates the bounding box by embedding a virtual
               rectangle (x1,y1,x2,y2). The points (x1,y1) and (x2,y2) denote two diagonal
               corners of the rectangle given in TeX point units.

           dvisvgm:bbox f[ix] x1 y1 x2 y2
               This variant of the bbox special assigns an absolute (final) bounding box to the
               resulting SVG. After executing this command, dvisvgm doesn’t further alter the
               bounding box coordinates, except this special is called again later. The points
               (x1,y1) and (x2,y2) denote two diagonal corners of the rectangle given in TeX
               point units.

               The following TeX snippet adds two raw SVG elements to the output and updates the
               bounding box accordingly:

                   \special{dvisvgm:raw <circle cx='{?x}' cy='{?y}' r='10' stroke='black' fill='red'/>}
                   \special{dvisvgm:bbox 20 10 10}

                   \special{dvisvgm:raw <path d='M50 200 L10 250 H100 Z' stroke='black' fill='blue'/>}
                   \special{dvisvgm:bbox abs 10 200 100 250}

           These specials were introduced with the emTeX distribution by Eberhard Mattes. They
           provide line drawing statements, instructions for embedding MSP, PCX, and BMP image
           files, as well as two PCL commands. dvisvgm supports only the line drawing statements
           and ignores all other em specials silently. A description of the command syntax can be
           found in the DVI driver documentation coming with emTeX (see CTAN).

           pdfTeX and dvipdfmx introduced several special commands related to the generation of
           PDF files. Currently, only two of them, pdf:mapfile and pdf:mapline are supported by
           dvisvgm. These specials allow modifying the font map tree during the processing of DVI
           files. They are used by CTeX, for example. dvisvgm supports both, the dvips and
           dvipdfm font map format. For further information on the command syntax and semantics,
           see the documentation of \pdfmapfile in the pdfTeX user manual.

           The famous DVI driver dvips introduced its own set of specials in order to embed
           PostScript code into DVI files, which greatly improves the capabilities of DVI
           documents. One aim of dvisvgm is to completely evaluate all PostScript snippets and to
           convert a large amount of it to SVG. However, in contrast to dvips, dvisvgm uses
           floating point arithmetics to compute the precise position of each graphic element,
           i.e. it doesn’t round the coordinates. Therefore, the relative locations of the
           graphic elements may slightly differ from those computed by dvips.

           Since PostScript is a rather complex language, dvisvgm does not try to implement its
           own PostScript interpreter but relies on Ghostscript instead. If the Ghostscript
           library was not linked while building dvisvgm, it is looked up and loaded dynamically
           during runtime. In this case, dvisvgm looks for on Unix-like systems, and for
           gsdll32.dll or gsdll64.dll on Windows. You can override these default file names with
           environment variable LIBGS or the command-line option --libgs. The library must be
           installed and reachable through the ld search path (*nix) or the PATH environment
           variable (Windows). If it cannot be found, the processing of PostScript specials is
           disabled. Use option --list-specials to check whether PS support is available, i.e.
           the entry ps is present.

           The TPIC special set defines instructions for drawing simple geometric objects. Some
           LaTeX packages, like eepic and tplot, use these specials to describe graphics.


           dvisvgm file

       Converts the first page of file.dvi to file.svg.

           dvisvgm -z file

       Converts the first page of file.dvi to file.svgz with default compression level 9.

           dvisvgm -p5 -z3 -ba4-l -onewfile file

       Converts the fifth page of file.dvi to newfile.svgz with compression level 3. The bounding
       box is set to DIN/ISO A4 in landscape format.

           dvisvgm --transform="R20,w/3,2h/5 T1cm,1cm S2,3" file

       Converts the first page of file.dvi to file.svg where three transformations are applied.


       dvisvgm uses the kpathsea library for locating the files that it opens. Hence, the
       environment variables described in the library’s documentation influence the converter.

       If dvisvgm was linked without the Ghostscript library, and if PostScript support has not
       been disabled, the shared Ghostscript library is looked up during runtime via dlopen().
       The environment variable LIBGS can be used to specify path and file name of the library.

       The pre-compiled Windows versions of dvisvgm require a working installation of MiKTeX 2.9
       or above. dvisvgm does not work together with the portable edition of MiKTeX because it
       relies on MiKTeX’s COM interface only accessible in a local installation. To enable the
       evaluation of PostScript specials, the original Ghostscript DLL gsdll32.dll must be
       present and reachable through the search path. 64-bit Windows builds require the 64-bit
       Ghostscript DLL gsdll64.dll. Both DLLs come with the corresponding Ghostscript installers
       available from

       The environment variable DVISVGM_COLORS specifies the colors used to highlight various
       parts of dvisvgm’s message output. It is only evaluated if option --color is given. The
       value of DVISVGM_COLORS is a list of colon-separated entries of the form gg=BF, where gg
       denotes one of the color group indicators listed below, and BF are two hexadecimal digits
       specifying the background (first digit) and foreground/text color (second digit). The
       color color values are defined as follows: 0=black, 1=red, 2=green, 3=yellow, 4=blue,
       5=magenta, 6=cyan, 7=gray, 8=bright red, 9=bright green, A=bright yellow, B=bright blue,
       C=bright magenta, D=bright cyan, E=bright gray, F=white. Depending on the terminal, the
       colors may differ. Rather than changing both the text and background color, it’s also
       possible to change only one of them: An asterisk (*) in place of a hexadecimal digit
       indicates the default text or background color of the terminal.

       All malformed entries in the list are silently ignored.

       er   error messages

       wn   warning messages

       pn   messages about page numbers
