Check if font family exists. — font_family_exists • gdtools

Check if a font family exists in available fonts.

Usage

font_family_exists(font_family = "sans", system_only = FALSE)

Arguments

font_family: font family name (case sensitive)
system_only: If TRUE, only look in system-installed fonts (as returned by systemfonts::system_fonts()). 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 FALSE (the default), both system and registered fonts are considered.

Value
