type: string, default:
Allows user control of how basic fontnames are represented in SVG output.
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.
