Since the current SVG standard 1\&.1 doesn\(cqt 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 \fB\-p\fR which is described below\&. +.sp +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 \fIDVI specials\fR\&. For a more detailed overview, see section \fBsupport of specials\fR below\&. +.sp +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\&. +.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, dvisvgm 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 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 +\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 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\&. Thus, +\fB\-\-trace\-all\fR +cannot be combined with option +\fB\-\-cache=none\fR\&. +.sp .5v +.RE +.RE +.PP +\fB\-b, \-\-bbox\fR=\fIfmt\fR +.RS 4 +Sets the bounding box of the generated graphic to the specified format\&. 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\&.

For symmetry reasons you can also explicitly add +\fB\-portrait\fR +or +\fB\-p\fR +to indicate the default portrait format\&.

Furthermore, it is also possible to disable the font caching mechanism completely with option +\fB\-\-cache=none\fR\&.

Additionally, outdated and corrupted cache files are removed\&. +.RE +.PP +\fB\-\-color\fR +.RS 4 +Enables colorization of messages printed during the conversion process\&.

See the ENVIRONMENT section below for further information\&. +.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 a 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, 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\&.

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 (on Unix\-like systems) or gsdll32\&.dll (Windows)\&. Option +\fB\-\-libgs\fR +can be used to give a different name\&. Alternatively, it\(cqs also possible to set the GS library name by the environment variable +LIBGS\&. The latter has 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\&. In most cases, 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 used to look up font names and encodings\&. dvisvgm does not provide its own map file but tries to read available ones coming with dvips or dvipdfm\&. If option +\fB\-m\fR +is not given, dvisvgm looks for +ps2pk\&.map, +dvipdfm\&.map, and +psfonts\&.map +(in this order)\&. Without further options, the file specified by option +\fB\-m\fR +will be used instead of the default maps\&. If you want dvisgvm 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 map file formats, see the manuals of dvips and dvipdfm\&. +.RE +.PP +\fB\-M, \-\-mag\fR=\fIfactor\fR +.RS 4 +Sets the maginfication 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\&. +.RE +.PP +\fB\-n, \-\-no\-fonts\fR[=\fIvariant\fR] +.RS 4 +If this option is given, dvisvgm doesn\(cqt create SVG +\fIfont\fR +elements but uses +\fIpaths\fR +instead\&. The resulting SVG files tends to be larger but concurrently more compatible with most applications that don\(cqt support SVG fonts yet\&. The optional argument +\fIvariant\fR +selects the method how to substitute fonts by paths\&. Variant 0 creates +\fIpath\fR +and +\fIuse\fR +elements\&. Variant 1 creates +\fIpath\fR +elements only\&.

All unsupported special statements are silently ignored\&. +.RE +.PP +\fB\-\-no\-styles\fR +.RS 4 +By default, dvisvgm creates 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 dvisvgm can\(cqt find a font file through the kpathsea lookup mechanism, it calls the external tools mktextfm or mktexmf by\&. This option disables these calls\&. +.RE +.PP +\fB\-o, \-\-output\fR=\fIpattern\fR +.RS 4 +Sets the name pattern of the output file\&. 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\&. The default 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 indicates dereferenced 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\&. 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 +\fB\-\-page\fR +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: +\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\&.

For an overview of the command syntax, see the documentation of dvips, for instance\&. +.RE +.PP +\fBcolor\fR +.RS 4 +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\&. +.RE +.PP +\fBdvisvgm\fR +.RS 4 +dvisvgm offers its own small set of specials\&. The following list gives a brief overview\&. +.PP +\fBdvisvgm:raw\fR \fItext\fR +.RS 4 +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 +\fItext\fR +may contain the macros +\fB{?x}\fR, +\fB{?y}\fR, and +\fB{?color}\fR +that are expanded to the current +\fIx\fR +or +\fIy\fR +coordinate and the current color, respectively\&.

JPEG, PNG, and SVG images can be used here\&. However, dvisvgm does not check the file format or the file name suffix\&. The lengths +\fIwidth\fR +and +\fIheight\fR +must be given as plain floating point numbers in TeX point units (1in = 72\&.27pt)\&. +.RE +.PP +\fBdvisvgm:bbox\fR n[ew] \fIname\fR +.RS 4 +Defines or resets a local bounding box called +\fIname\fR\&. 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 +\fB{?bbox \fR\fB\fIname\fR\fR\fB}\fR +expands to the four values +\fIx\fR, +\fIy\fR, +\fIw\fR, and +\fIh\fR +(separated by spaces) specifying the coordinates of the upper left corner, width, and height of the local box +\fIname\fR\&. If box +\fIname\fR +wasn\(cqt previously defined, all four values equal zero\&. +.RE +.PP +\fBdvisvgm:bbox\fR \fIwidth\fR \fIheight\fR [\fIdepth\fR] +.RS 4 +Updates the bounding box of the current page by embedding a virtual rectangle (\fIx\fR, +\fIy\fR, +\fIwidth\fR, +\fIheight\fR) where the lower left corner is located at the current DVI drawing position (\fIx\fR,\fIy\fR)\&. If the optional parameter +\fIdepth\fR +is specified, dvisvgm embeds a second rectangle (\fIx\fR, +\fIy\fR, +\fIwidth\fR, \-\fIdepth\fR)\&. The lengths +\fIwidth\fR, +\fIheight\fR +and +\fIdepth\fR +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\(cqs not possible to reduce its extent\&. This special should be used in conjunction with +\fBdvisvgm:raw\fR +in order to update the viewport of the page properly\&. +.RE +.PP +\fBdvisvgm:bbox\fR a[bs] \fIx1\fR \fIy1\fR \fIx2\fR \fIy2\fR +.RS 4 +This variant of the bbox special updates the bounding box by embedding a virtual rectangle (\fIx1\fR,\fIy1\fR,\fIx2\fR,\fIy2\fR)\&.

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)\&. +.RE +.PP +\fBps\fR +.RS 4 +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\(cqt round the corrdinates\&. Therefore, the relative locations of the graphic elements may slightly differ from those computed by dvips\&. +.sp +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 dynamically loaded during runtime\&. In this case, dvisvgm looks for +\fIlibgs\&.so\fR +on Unix\-like systems, and for +\fIgsdll32\&.dll\fR +on Windows\&. You can override these default file names with the environment variable +LIBGS\&. The library must be installed and must be reachable through the ld search path (*nix) or the PATH environment variable (Windows)\&.

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. + + +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*;; + A__n__, B__n__, C__n__, D__n__, 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*;; +[horizontal] + *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, --scale*='sx'[,'sy']:: +Scales the page content horizontally by 'sx' and vertically by 'sy'. This option is equivalent +to *-TS*'sx','sy'. + + +*-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. + + +*--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, --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. + + +*-h, --help*:: +Prints a short summary of all available command-line options. +This is also the default action if dvisvgm is called without parameters. + + +*--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 (on Unix-like systems) or gsdll32.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'. + + +*--keep*:: +Disables the removal of temporary files as created by Metafont (usually .gf, .tfm, and .log files). + + +*-m, --map-file*='file':: +Sets the map file used to look up font names and encodings. dvisvgm does not provide +its own map file but tries to read available ones coming with dvips or dvipdfm. If +option *-m* is not given, dvisvgm looks for +ps2pk.map+, +dvipdfm.map+, and +psfonts.map+ (in this order). +Without further options, the file specified by option *-m* will be used instead of the +default maps. If you want dvisgvm to load the given file additionally to the default maps, add a +leading '+' to the file/path, e.g. `--map-file=+myfonts.map`. +For further information about the map file formats, see the manuals of dvips and dvipdfm. + + +*-M, --mag*='factor':: +Sets the maginfication 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. + + +*-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*. + + +*-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*. + + +*--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. + + +*-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. + + +*-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 *-TR*'angle'. + + +*-s, --stdout*:: +Don't write the SVG output to a file but redirect it to *stdout*. + + +*-t, --translate*='tx'[,'ty']:: +Translates (moves) the page content in direction of vector ('tx','ty'). This option is +equivalent to *-TT*'tx','ty'. + + +*-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+180__k__, 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+180__k__, 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. ++ +[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: + +[horizontal] +*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. + +================================================================================================= ++ +// + +// +*-v, --verbosity*='level':: +Controls the type of messages printed during a dvisvgm run: +[horizontal] + *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*. + + +SUPPORT OF SPECIALS +------------------- +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). + +*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. In the current version, this rectangle always gets the size +of the minimal bounding box. This 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 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} +------------------------------------------------------------------------------------ ++ + +*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 package uses a set of HTML anchor tags to indicate hyperlinks in DVI files. +// dvisvgm converts them to corresponding SVG elements. + +*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 corrdinates. 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 dynamically loaded +during runtime. In this case, dvisvgm looks for 'libgs.so' on Unix-like systems, and for 'gsdll32.dll' on Windows. +You can override these default file names with the environment variable +LIBGS+. +The library must be installed and must be reachable through the ld search path (\*nix) or the PATH environment +variable (Windows). If it cannot be found, the evaluation of PostScript specials is disabled. +Use option *--list-specials* to check whether PS support is available, i.e. the entry 'ps' is present. + +*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 version of dvisvgm requires a working installation of MiKTeX 2.9 or above. +To enable evaluation of PostScript specials, the original Ghostscript DLL 'gsdll32.dll' must be present +and reachable through the search path. + +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. + +[horizontal] +*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 *kpsewhich* utility. + +[horizontal] +**.enc*:: Font encoding files +**.fgd*:: Font glyph data files (cache files created by dvisvgm) +**.map*:: Font map files +**.mf*:: Metafont input files +**.pfb*:: PostScript Type 1 font files +**.pro*:: PostScript header/prologue files +**.tfm*:: TeX font metric files +**.ttf*:: TrueType font files +**.vf*:: Virtual font files + +SEE ALSO +-------- +*tex(1), mf(1), mktexmf(1), grodvi(1), potrace(1)*, and the *kpathsea library* info documentation. + + +RESOURCES +--------- +Project home page::: http://dvisvgm.sourceforge.net +SourceForge project site::: http://sourceforge.net/projects/dvisvgm + + +AUTHOR +------ +Written by {author} <{email}> + + +COPYING +------- +Copyright (C) 2005-2012 Martin Gieseking.
