Since the current SVG standard 1\&.1 doesn\(cqt specify multi\-page graphics, \fBdvisvgm\fR 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 \fB\-p\fR which is described below\&. -.sp -\fBdvisvgm\fR 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 \fIDVI specials\fR\&. For a more detailed overview, see section \fBsupport of specials\fR below\&. -.sp -As SVG is a vector based graphics format, \fBdvisvgm\fR 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 \fBdvisvgm\fR is able to find a PFB file for a required font, it will read the necessary information from it\&. -.sp -TeX\(cqs main source for font descriptions is Metafont though, which produces bitmap output\&. That\(cqs why not all obtainable TeX fonts are available in PFB format\&. In these cases \fBdvisvgm\fR tries to vectorize Metafont\(cqs 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\&. -.SH "OPTIONS" -.PP -\fB\-a, \-\-trace\-all\fR=[\fIretrace\fR] -.RS 4 -This option forces dvisvgm to trace not just 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 -\fB\-\-trace\-all\fR) 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 -\fIretrace\fR -determines how to handle glyphs that are already stored in the cache\&. By default, these glyphs are skipped\&. Setting argument -\fIretrace\fR -to -\fIyes\fR -or -\fItrue\fR -forces dvisvgm to trace the corresponding bitmaps again\&. -.if n \{\ -.sp -.\} -.RS 4 -.it 1 an-trap -.nr an-no-space-flag 1 -.nr an-break-flag 1 -.br -.ps +1 -\fBNote\fR -.ps -1 -.br -This option only takes affect if font caching is active\&.

The parameter -\fIfmt\fR -takes either one of the format specifiers listed below or a sequence of four comma\- or whitespace\-separated length values -\fIx1\fR, -\fIy1\fR, -\fIx2\fR -and -\fIy2\fR\&. 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\&. -.sp -It\(cqs also possible to give only one length value -\fIl\fR\&. In this case the minimal bounding box is computed and enlarged by adding (\-\fIl\fR,\-\fIl\fR) to the upper left and (\fIl\fR,\fIl\fR) to the lower right corner\&. -.sp -Alternatively, the following format specifiers are supported: -.PP -\fBInternational DIN/ISO paper sizes\fR -.RS 4 -A\fIn\fR, B\fIn\fR, C\fIn\fR, D\fIn\fR, where -\fIn\fR -is a non\-negative integer, e\&.g\&.

By default, these files are stored in $HOME/\&.dvisvgm\&. If you prefer a different location use option -\fB\-\-cache\fR -to overwrite the default\&. Furthermore, it is also possible to disable the font caching mechanism completely with option -\fB\-\-cache=none\fR\&. If argument -\fIdir\fR -is omitted, dvisvgm prints the path of the default cache directory and some information about the stored fonts\&. -.RE -.PP -\fB\-\-color\fR -.RS 4 -Enables colorization of messages printed during the conversion process\&. -.RE -.PP -\fB\-e, \-\-exact\fR -.RS 4 -If this option is given, dvisvgm computes the precise bounding box of each character\&. By default, the values stored in the font\(cqs TFM file are used to determine a glyph\(cqs extent\&. As these values are intended to realize optimal character placements and are not designed to represent the exact dimensions, they don\(cqt necessarily correspond with the bounds of the visual glyphs\&. Thus, the 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 -\fB\-\-exact\fR, dvisvgm analyzes the actual shape of each character and derives a usually tight bounding box\&. -.RE -.PP -\fB\-h, \-\-help\fR -.RS 4 -Prints a short summary of all available command\-line options\&. -.RE -.PP -\fB\-\-libgs=filename\fR -.RS 4 -This option is only available if the Ghostscript library is not directly linked to dvisvgm and PostScript support was not completely disabled\&. In this case, dvisvgm tries to load the shared GS library dynamically during runtime\&. By default, it expects the library\(cqs name to be libgs\&.so (Linux) or gsdll32\&.dll (Windows)\&. Option -\fB\-\-libgs\fR -can be used to give a different name\&. Alternatively, the GS library name can also be set by the environment variable -\fBLIBGS\fR\&. The latter has a less precedence than the command\-line option\&. -.RE -.PP -\fB\-l, \-\-list\-specials\fR -.RS 4 -Prints a list of registered special handlers and exits\&. Each handler processes a set of special statements belonging to the same category\&. The categories are identified by the prefix of the special statements\&. It\(cqs usually a leading word separated from the rest of the statement by a colon or a blank, e\&.g\&. -\fIcolor\fR -or -\fIps\fR\&. -.RE -.PP -\fB\-\-keep\fR -.RS 4 -Disables the removal of temporary files as created by Metafont (usually \&.gf, \&.tfm, and \&.log files)\&. -.RE -.PP -\fB\-m, \-\-map\-file\fR=\fIfile\fR -.RS 4 -Sets the map file that is used to look up font names and encodings\&. -\fBdvisvgm\fR -does not provide its own map file but tries to use available ones coming with -\fBdvips\fR -or -\fBdvipdfm\fR\&.

Without further options, the file specified by option -\fB\-m\fR -will be used instead of the default maps\&. If you want -\fBdvisgvm\fR -to load the given file additionally to the default maps, add a leading -\fI+\fR -to the file/path, e\&.g\&. -\-\-map\-file=+myfonts\&.map\&. For further information about the file format see the manuals of -\fBdvips\fR -and -\fBdvipdfm\fR\&. -.RE -.PP -\fB\-M, \-\-mag\fR=\fIfactor\fR -.RS 4 -Sets the maginfication factor used for 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\&. -.RE -.PP -\fB\-n, \-\-no\-fonts\fR -.RS 4 -If this option is given, -\fBdvisvgm\fR -doesn\(cqt create font elements but uses paths instead\&. The resulting SVG file is usually bigger but concurrently more compatible with most applications that don\(cqt support SVG fonts yet\&. This option implies -\fB\-\-no\-styles\fR\&. -.RE -.PP -\fB\-S, \-\-no\-specials\fR[=\fInames\fR] -.RS 4 -Disable processing of special commands that are 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 -\fIname\fR -is a unique identifier referencing a special handler\&. Option -\fB\-\-list\-specials\fR -lists all currently available handlers and their names\&. All unsupported special statements are silently ignored\&. -.RE -.PP -\fB\-\-no\-styles\fR -.RS 4 -By default, -\fBdvisvgm\fR -uses CSS styles and class attributes to reference fonts because it\(cqs 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 -\fB\-\-no\-styles\fR\&. -.RE -.PP -\fB\-\-no\-mktexmf\fR -.RS 4 -Suppresses the generation of missing font files\&. If -\fBdvisvgm\fR -can\(cqt find a font file through the kpathsea lookup mechanism, it calls the external tools mktextfm or mktexmf by default\&. This option disables these calls\&. -.RE -.PP -\fB\-o, \-\-output\fR=\fIpattern\fR -.RS 4 -Sets the name pattern of the output file\&. The parameter -\fIpattern\fR -is a string that may contain the variables -\fB%f\fR -and -\fB%p\fR\&. -\fB%f\fR -stands for the base name of the DVI file, i\&.e\&. the DVI filename without suffix, and -\fB%p\fR -is the current page number\&. By default, the pattern is -\fB%f\-%p\&.svg\fR -if the DVI file consists of more than one page, and -\fB%f\&.svg\fR -otherwise\&. That means, a DVI file -\fIfoo\&.dvi\fR -is converted to -\fIfoo\&.svg\fR -if -\fIfoo\&.dvi\fR -is a single\-page document\&. Otherwise, multiple SVG files -\fIfoo\-01\&.svg\fR, -\fIfoo\-02\&.svg\fR, etc\&. are produced\&. In Windows environments, the percent sign is used to get the value of environment variables, and must therefore be protected by a second percent sign, e\&.g\&. -\fB\-\-output=%%f\-%%p\fR\&. -.RE -.PP -\fB\-p, \-\-page\fR=\fIranges\fR -.RS 4 -This option sets the pages to be processed\&. Parameter -\fIranges\fR -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\(cqt matter if a page is given more than once or if page ranges overlap\&. -\fBdvisvgm\fR -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 -\fB\-\-page\fR -is not given\&. 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: -\fB\-\-page=\-10\fR -converts all pages up to page 10, -\fB\-\-page=10\-\fR -converts all pages starting with page 10\&. Please consider that the page values don\(cqt refer to the page numbers printed on the page\&. Instead, the physical page count is expected, where the first page always gets number 1\&. -.RE -.PP -\fB\-P, \-\-progress\fR[=\fIdelay\fR] -.RS 4 -Enables a simple progress indicator shown when time\-consuming operations like PostScript specials are processed\&. The indicator doesn\(cqt appear before the given delay (in seconds)\&. The default delay value is 0\&.5 seconds\&. -.RE -.PP -\fB\-r, \-\-rotate\fR=\fIangle\fR -.RS 4 -Rotates page content clockwise by -\fIangle\fR -degrees around the page center\&. This option is equivalent to -\fB\-TR\fR\fIangle\fR\&. -.RE -.PP -\fB\-s, \-\-stdout\fR -.RS 4 -Don\(cqt write output to a file but redirect it to -\fBstdout\fR\&. -.RE -.PP -\fB\-t, \-\-translate\fR=\fItx\fR[,\fIty\fR] -.RS 4 -Translates (moves) page content in direction of vector (\fItx\fR,\fIty\fR)\&.

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\&.
