cairo_surface_type_t

cairo_surface_type_t is used to describe the type of a given surface. The surface types are also known as "backends" or "surface backends" within cairo. The type of a surface is determined by the function used to create it, which will generally be of the form cairo_type_surface_create(), (though see cairo_surface_create_similar() as well). The surface type can be queried with cairo_surface_get_type() The various cairo_surface_t functions can be used with surfaces of any type, but some backends also provide type-specific functions that must only be called with a surface of the appropriate type. These functions have names that begin with cairo_type_surface such as cairo_image_surface_get_width(). The behavior of calling a type-specific function with a surface of the wrong type is undefined. New entries may be added in future versions.
