12 January 2018: dvisvgm 2.3.1 has been released
  • Fixed the width of characters slanted by a mapfile entry (issue #82).
  • If ttfautohint fails for a font, dvisvgm now uses the unhinted font and prints a corresponding warning message.
  • Some code cleanup.
28 December 2017: dvisvgm 2.3 has been released

This is a small feature release that adds optional experimental support for ttfautohint. ttfautohint usually creates better results than the FontForge autohinter that dvisvgm uses by default if you call it with option --font-format=woff,autohint, for example. The fonts embedded in the following SVG file were hinted with ttfautohint:

In order to build dvisvgm with ttfautohint support, you need the ttfautohint library and the corresponding header files which are provided as of the latest version 1.8.1. A pre-built DLL of ttfautohint for Windows can be found here. By default, ttfautohint support is completely disabled and not available in dvisvgm. To enable it, add option --with-ttfautohint to the configure script, and optionally specify the location of the ttfautohint development files, e.g. --with-ttfautohint=/opt/ttfautohint. Depending on the configuration results, the ttfautohint library is either directly linked to the dvisvgm binary or looked up dynamically when running dvisvgm. If ttfautohint support is available, the list printed when calling dvisvgm with option -V1 contains a corresponding entry, as shown in the box on the right.
