The Web Open Font Format (short WOFF; here using Aladin font) is several years old. Still it took some time to get to a point, where WOFF is almost painless to use on the linux desktop. WOFF is based on OpenType style fonts and is in some way similar to the more known True Type Font (.ttf). TTF fonts are widely known and used on the Windows platform. Those feature rich kind of fonts are used for high quality font displaying for the system and local office-and design documents. WOFF aims at closing the gap towards making those features available on the web. With these fonts it becomes possible to show nice looking fonts on paper and web presentations in almost the same way. In order to make WOFF a success, several open source projects joined forces, among them Pango and Qt, and contributed to harfbuzz, a OpenType text shaping engine. Firefox and other web engines can handle WOFF inside SVG web graphics and HTML web documents using harfbuzz. Inkscape uses at least since version 0.91.1 harfbuzz too for text inside SVG web graphics. As Inkscape is able to produce PDF’s, designing for both the web and print world at the same time becomes easier on Linux.
How to install WOFF?
For using inside inkscape one needs to install the fonts locally. Just copy the fonts to your personal ~/.fonts/ path and run
fc-cache -f -v
After that procedure the fonts are visible inside a newly started Inkscape.
How to deploy SVG and WOFF on the Web?
Thankfully WOFF in SVG documents is similar to HTML documents. However simply uploading a Inkscape SVG to the web as is will not be enough to show WOFF fonts. While viewing the document locally is fine, Firefox and friends need to find those fonts independent of the localy installed fonts. Right now you need to manually edit your Inkscape SVG to point to the online location of your fonts . For that open the SVG file in a text editor and place a CSS font-face reference right after the <svg> element like:
src: url(“fonts/Aladin-Regular.woff”) format(“woff”);
How to print a Inkscape SVG document containing WOFF?
Just convert to PDF from Inkscape’s file menue. Inkscape takes care for embedding the needed fonts and creates a portable PDF.
In case your prefered software is not yet WOFF ready, try the woff2otf python script for converting to the old TTF format.
Hope this small post gets some of you on the font fun path.
