Einführung

An opaque structure holding all options that are used when rendering fonts.

Individual features of a cairo_font_options_t can be set or accessed using functions named cairo_font_options_set_feature_name and cairo_font_options_get_feature_name, like cairo_font_options_set_antialias() and cairo_font_options_get_antialias().

New features may be added to CairoFontOptions in the future. For this reason CairoFontOptions::copy, CairoFontOptions::equal, CairoFontOptions::merge, CairoFontOptions::hash (cairo_font_options_copy(), cairo_font_options_equal(), cairo_font_options_merge(), and cairo_font_options_hash() in procedural way) should be used to copy, check for equality, merge, or compute a hash value of CairoFontOptions objects.
