getSize
Gets the size field of a font description.
See method@Pango.FontDescription.set_size.
Return
the size field for the font description in points or device units. You must call method@Pango.FontDescription.get_size_is_absolute to find out which is the case. Returns 0 if the size field has not previously been set or it has been set to 0 explicitly. Use method@Pango.FontDescription.get_set_fields to find out if the field was explicitly set or not.
