cairo:surface-font-options (surface options)

surface -- a cairo:surface-t instance
options -- a cairo:font-options-t instance into which to store the retrieved options, all existing values are overwritten

The cairo:font-options-t instance with the retrieved options.

Retrieves the default font rendering options for the surface. This allows display surfaces to report the correct subpixel order for rendering on them, print surfaces to disable hinting of metrics and so forth. The result can then be used with the cairo:scaled-font-create function.
