dvisvgm -- A DVI to SVG converter
DESCRIPTION
dvisvgm is a utility for TeX/LaTeX users. It converts DVI and EPS files to
the XML-based scalable vector graphics format SVG.
DEPENDENCIES
dvisvgm relies on the following free libraries:
* Clipper (http://www.angusj.com/delphi/clipper.php)
To compute the intersections of two curved paths, dvisvgm flattens the paths
to polygons, intersects them using Clipper, and reconstructs the curves
afterwards.
* FontForge library (https://www.fontforge.org)
dvisvgm can be built with optional WOFF support that allows to embed the
font data in WOFF or TrueType format rather than as SVG. The FontForge
library provides the required functions to create font files in these
formats. A reduced version of the library is bundled with the dvisvgm
sources. It's also available at https://github.com/mgieseki/ff-woff.
* FreeType 2 (http://www.freetype.org)
This library is used to extract the glyph outlines from vector fonts
(PFB, OTF, TTF).
* Ghostscript (https://www.ghostscript.com)
The PostScript special handler requires the Ghostscript library
libgs.so (Linux) or gsdll32.dll/gsdll64.dll (Windows) to be installed.
If the configure script finds the corresponding Ghostscript development
files on the system, it directly links against libgs.so.N, where N is the
library's ABI version. Otherwise, the library is looked up at runtime,
and PostScript support is enabled only if libgs.so can be found.
Due to incompatible changes of the Ghostscript API, dvisvgm requires
Ghostscript 8.31 or later.
* kpathsea (https://tug.org/kpathsea)
This library is part of the Web2C package and is usually installed in
conjunction with a TeX distribution. kpathsea provides functions for
searching files in the large texmf tree. Please ensure that you use the
kpathsea version coming with or matching your TeX system.
* potracelib (http://potrace.sourceforge.net)
Peter Selinger's bitmap tracing library is utilized to vectorize Metafont's
bitmap output.
* woff2 and brotli (https://github.com/google/woff2)
These Google libraries are bundled with the dvisvgm sources. They are used
to create WOFF2 from TrueType fonts.
* xxHash (https://github.com/Cyan4973/xxHash)
The xxHash library provides a fast hash algorithm. dvisvgm uses it to
create unique integer values from PostScript character names in order to
store them in a compact way together with their Unicode points. A recent
version of xxHash is bundled with the dvisvgm sources.
* zlib (http://www.zlib.org)
Compressed SVG files are produced by using functions of this library and the
Gzstream wrapper classes (http://www.cs.unc.edu/Research/compgeom/gzstream)
which are licensed under LGPL version 2.1 (or optionally any later version)
and should be included with this package.
If you want to build and run the test suite located in the tests subdirectory,
you also need the Google Test libraries (https://github.com/google/googletest).
BUILDING DVISVGM FROM SOURCE
dvisvgm is written in C++11 (ISO C++ standard 2011) and requires an appropriate
compiler, like GCC 4.8.1, Clang 3.3, or any later version. The configure script
checks for the availability of C++11 support and adds the proper compiler
options if necessary.
Quick installation info:
* type "./autogen.sh" if "configure" is not present in the dvisvgm
root folder
* type "./configure"
* type "make"
* type "make install" as root (or "sudo make install")
For generic configuration instructions see the file INSTALL.
The configure script should recognize all necessary parameters.
If a library is installed but not detected, specify its location
as commandline parameter of configure, e.g.
./configure --with-freetype=/usr/local/freetype
(all available options can be displayed with ./configure --help)
The tracer module calls Metafont in case of lacking TFM or PFB files
via a system call. Please ensure that Metafont is installed and
reachable through the system's search path.
If you don't like compiling the sources yourself, you can
download pre-compiled executables for Windows and MiKTeX
from the project website instead (see below).
USAGE
Information about the command-line interface and the available options can be
found in the manual page.
ADDITIONAL INFORMATION
This package is available from CTAN (dviware/dvisvgm) and can be downloaded
from the project website as well:
http://dvisvgm.bplaced.net
Here you can find the sources, pre-compiled binaries and further additional
information about the converter and related topics.
If you've found a bug, please let me know. You can either send me an email or
preferably use the bug tracker at GitHub (https://github.com/mgieseki/dvisvgm).
