font_family_exists

Check if a font family exists in available fonts.

Compute text metrics (width, ascent, descent) using 'Cairo'
and 'FreeType', independently of the active graphic device. Font
lookup is delegated to 'systemfonts'. Additional utilities let users
register 'Google Fonts' or bundled 'Liberation' fonts, check font
availability, and assemble 'htmlDependency' objects so that fonts are
correctly embedded in 'Shiny' applications, 'R Markdown' documents,
and 'htmlwidgets' outputs such as 'ggiraph'.

font_family_exists function

<dl><dt>font_family</dt>
<dd>font family name (case sensitive)</dd>
<dt>system_only</dt>
<dd>If <code>TRUE</code>, only look in system-installed fonts
(as returned by <code><a href="/link/systemfonts%3A%3Asystem_fonts()?package=gdtools&version=0.5.0" data-mini-rdoc="gdtools::systemfonts::system_fonts()">systemfonts::system_fonts()</a></code>). This is useful
to verify that a font will be found by fontconfig, which is the
font resolution mechanism used by Cairo devices at rendering
time. When <code>FALSE</code> (the default), both system and registered
fonts are considered.</dd></dl>
