cairo_surface_type_t.Rd#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.
cairo_surface_type_t
An object of class list of length 25.
The type of a surface is determined by the function used to create it, which will generally be of the form <function>cairo_<emphasis>type</emphasis>_surface_create(<!-- -->)</function>, (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 <literal>cairo_<emphasis>type</emphasis>_surface</literal> 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.
