1. and the XeTeX formats 5 and 6 which are also known as XDV Besides the basic DVI commands dvisvgm also evaluates many so called specials which heavily extend the capabilities of the plain DVI format For a more detailed overview see section Supported 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 fonts referenced in a DVI page section to scalable path descriptions The fastest way to achieve this is to extract the path information from vector based font files available 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 it creates font el2. mf Metafont input files pfb PostScript Type 1 font files pro PostScript header prologue files tfm TeX font metric files ttf TrueType font files wvf Virtual font files dvisvgm 1 13 2015 12 08 dvisvgm Manual 12 SEE ALSO tex 1 mf 1 mktexmf 1 grodvi 1 potrace 1 and the kpathsea library info documentation RESOURCES Project home page http dvisvgm bplaced net Code repository https github com mgieseki dvisvgm BUGS Please report bugs using the bug tracker at GitHub AUTHOR Written by Martin Gieseking lt martin gieseking uos de gt COPYING Copyright 2005 2015 Martin Gieseking Free use of this software is granted under the terms of the GNU General Public License GPL version 3 or at your option any later version dvisvgm 1 13 2015 12 08

28. ven 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 specify ing 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 x 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 enc Font encoding files fgd Font glyph data files cache files created by dvisvgm map Font map files
