type: string, default:
fontnames is undefined or
svg, the output will try to use known SVG
For example, the default font
Times-Roman will be mapped to the
basic SVG font
serif. This can be overridden by setting
hd. In the former case, known PostScript font names such as
Times-Roman will be used in the output. In the latter case, the fontconfig
font conventions are used. Thus,
Times-Roman would be treated as
Nimbus Roman No9 L. These last two options are useful with SVG viewers that support
these richer fontname spaces.
Note: svg only.
