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

SYNOPSIS
       dvisvgm [ options ] file [.dvi]

       dvisvgm -E [ options ] file [.eps]

DESCRIPTION
       The command-line utility dvisvgm converts DVI files, as generated by
       TeX/LaTeX, to the XML-based scalable vector graphics format SVG. It
       supports the classic DVI format 2 as well as format 3 (created by pTeX
       in vertical mode), and format 5 which is also known as XDV (created by
       XeTeX). Besides the basic DVI commands, dvisvgm also evaluates many
       so-called specials which heavily extend the capabilities of the DVI
       format. For a more detailed overview, see section support of specials
       below.

       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.

       SVG is a vector-based graphics format and therefore dvisvgm tries to
       convert the glyph outlines of all used fonts to scalable path
       descriptions. The fastest way to do that is to extract the path
       information from font files in PFB, TTF, or OTF format. If dvisvgm is
       able to find such a file, it extracts all necessary outline information
       about the glyphs from it.

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

       When running dvisvgm without option --no-fonts, font elements
       (<font>...</font>) are used to embed the font data into the SVG files.
       Unfortunately, only few SVG renderes support these elements yet. Most
       web browsers and vector graphics applications don't evaluate them
       properly so that the text components of the resulting graphics might
       look strange. In order to create more compatible SVG files,
       command-line option --no-fonts can be given to replace the font
       elements by plain graphics paths.

OPTIONS
       -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.

               Note
               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 x 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.

                   Note
                   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
           together with further information about the stored fonts.
           Additionally, outdated and corrupted cache files are removed.

       -j, --clipjoin
           This option tells dvisvgm to compute the intersection of clipping
           paths itself if necessary, and not to delegate this task to the SVG
           renderer. The resulting SVG files are more portable because some
           SVG renderers don't support intersections of clipping paths which
           are defined by clipPath elements that contain a clip-path
           attribute.

       --color
           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 implement 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 (or smaller) than the
           respective TFM values. As a result, this can lead to clipped
           characters at the bounds of the SVG graphics. With option --exact
           given, 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 files but tries to read
           available ones coming with dvips or dvipdfm. If option --fontmap is
           omitted, dvisvgm looks for the default map files ps2pk.map,
           dvipdfm.map, and psfonts.map (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:

           +mapfile
               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.

           -mapfile
               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.

           =mapfile
               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: --fontmap=myfile1.map,+myfile2.map loads myfile1.map
               followed by myfile2.map where all redefinitions of myfile2.map
               are ignored.  --fontmap==myfile1.map,-myfile2.map loads the
               default map file followed by myfile1.map and myfile2.map where
               all redefinitions of myfile1.map replace previous entries.
               Afterwards, all definitions for the fonts given in myfile2.map
               are removed from the font map tree.

               For further information about the map file formats and the mode
               specifiers, see the manuals of dvips and dvipdfm.

       -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 names, while mode 2 sorts
           the lines by the long option names.

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

       --libgs=filename
           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 libgs.so.X (on
           Unix-like systems, where X is the ABI version of the library) 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, --linkmark=style
           Selects the method how to mark hyperlinked areas. The style
           argument can take one of the values none, box, and line, where box
           is the default, i.e. a rectangle is drawn around the linked region
           if option --linkmark is omitted. Style argument line just draws the
           lower edge of the bounding rectangle, and none tells dvisvgm not to
           add any visible objects to hyperlinks. The lines and boxes get the
           current text color selected. In order to apply a different,
           constant color, a colon followed by a color specifier can be
           appended to the style string. A color specifier is either a
           hexadecimal RGB value of the form #RRGGBB, or a dvips color name as
           listed here:
           http://en.wikibooks.org/wiki/LaTeX/Colors#The_68_standard_colors_known_to_dvips

           Moreover, argument style can take a single color specifier to
           highlight the linked region by a frameless box filled with that
           color. An optional second color specifier separated by colon
           selects the frame color.

           Examples: box:red or box:#ff0000 draws red boxes around the linked
           areas.  yellow:blue creates yellow filled rectangles with blue
           frames.

       -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.

       --no-mktexmf
           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 tend to be larger
           but they are 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.

       --no-styles
           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.
           --output=%%f-%%p.

       -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 1.

       -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.

       -R, --relative
           SVG allows to define graphics paths by a sequence of absolute
           and/or relative commands, i.e. each command expects either absolute
           coordinates or coordinates relative to the current drawing
           position. By default, dvisvgm creates paths made up of absolute
           commands. If option --relative is given, relative commands are
           created instead which slightly reduces the size of the SVG files in
           most cases.

       -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 3x3 matrix
               ((m1,m2,m3),(m4,m5,m6),(0,0,1)), where the inner triples denote
               the rows.

                   Note
                   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 units
                   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


               Note
               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.

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

       -Z, --zoom[=factor]
           Multiplies the width and height attributes of the SVG root element
           by argument factor while the coordinate system of the graphic is
           retained. As a result, most SVG viewers zoom the graphics
           accordingly. If a negative zoom factor is given, the width and
           height attributes are omitted.

SUPPORT OF SPECIALS
       dvisvgm supports several sets of special commands that can be used to
       enrich DVI files with additional features, like color, graphics, and
       hyperlinks. The evaluation of special commands is delegated to
       dedicated 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). This section gives an overview of
       the special commands currently supported.

       bgcolor
           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.

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

           dvisvgm:raw text
               Adds an arbitrary sequence of characters to the page section of
               the SVG document. 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 expressions {?x}, {?y},
               and {?color} that expand to the current x or y coordinate and
               the current color, respectively. Furthermore, {?nl} expands to
               a newline character.

           dvisvgm:rawdef text
               This command is similar to dvisvgm:raw, but puts the raw text
               into the <defs> section of the SVG document currently being
               generated.

           dvisvgm:rawset name ... dvisvgm:endrawset
               This pair of specials marks the begin and end of a definition
               of a named raw SVG fragment. All dvisvgm:raw and dvisvgm:rawdef
               specials enclosed by dvisvgm:rawset and dvisvgm:endrawset are
               not evaluated immediately but jointly stored under the given
               name for later use. Once defined, the named fragment can be
               referenced throughout the DVI file by dvisvgm:rawput (see
               below).  dvisvgm:rawset and dvisvgm:endrawset must not be
               nested, i.e. each call of dvisvgm:rawset has to be followed by
               a corresponding call of dvisvgm:endrawset before another
               dvisvgm:rawset may occur. Also, the identifier name must be
               unique throughout the DVI file. Using dvisvgm:rawset multiple
               times together with the same name leads to a warning message.

           dvisvgm:rawput name
               Inserts raw SVG fragments previously stored under the given
               name. dvisvgm distinguishes between fragments that were
               specified with dvisvgm:raw or dvisvgm:rawdef, and handles them
               differently: It inserts all dvisvgm:raw parts every time
               dvisvgm:rawput is called, whereas the dvisvgm:rawdef portions
               go to the <defs> section of the current SVG document only once.

           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}

       em
           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).

       html
           The hyperref specification defines several variants on how to mark
           hyperlinked areas in a DVI file. dvisvgm supports the plain
           HyperTeX special constructs as created with hyperref package option
           hypertex. By default, all linked areas of the document are marked
           by a rectangle. Option --linkmark allows to change this behavior.
           See above for further details. Information on syntax and semantics
           of the HyperTeX specials can be found in the hyperref manual.

       pdf
           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.

       ps
           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 to
           the dvisvgm binary, it is looked up and loaded dynamically during
           runtime. In this case, dvisvgm looks for libgs.so.X on Unix-like
           systems (supported ABI versions: 7,8,9), and for gsdll32.dll or
           gsdll64.dll on Windows. You can override the default file names
           with environment variable LIBGS or the command-line option --libgs.
           The library must be reachable through the ld search path (*nix) or
           the PATH environment variable (Windows). Alternatively, the
           absolute file path can be specified. If the library cannot be
           found, dvisvgm disables the processing of PostScript specials. Use
           option --list-specials to check whether PS support is available,
           i.e. entry ps is present.

           The PostScript handler also recognizes and evaluates bounding box
           data generated by the preview package with option tightpage. If the
           data is present in a DVI file, dvisvgm adapts the bounding box of
           the generated SVG file accordingly, and prints a message showing
           the width, height, and depth of the box in TeX point units.
           Especially, the depth value can be used to vertically align the SVG
           graphics with the baseline of surrounding text in HTML or XSL-FO
           documents, for example.

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

EXAMPLES
           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.

ENVIRONMENT
       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 www.ghostscript.com.

       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 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

       ps   page size messages

       fw   information about the
            files written

       sm   state messages

       tr   messages of the glyph
            tracer

       pi   progress indicator


       Example: er=01:pi=*5 sets the colors of error messages (er) to red (1)
       on black (0), and those of progress indicators (pi) to cyan (5) on
       default background (*).

FILES
       The location of the following files is determined by the kpathsea
       library. To check the actual kpathsea configuration you can use the
