### Create

- Goto spec in source

    function Create (Filename: String;Width_In_Point: Gdouble;Height_In_Point: Gdouble) return Cairo_Surface;

Creates a SVG surface of the specified size in points to be written to filename. The SVG surface backend recognizes the following MIME types for the data attached to a surface (see Cairo.Surface.Set_Mime_Data) when it is used as a source pattern for drawing on this surface: CAIRO_MIME_TYPE_JPEG, CAIRO_MIME_TYPE_PNG, CAIRO_MIME_TYPE_URI. If any of them is specified, the SVG backend emits a href with the content of MIME data instead of a surface snapshot (PNG, Base64-encoded) in the corresponding image tag. The unofficial MIME type CAIRO_MIME_TYPE_URI is examined first. If present, the URI is emitted as is: assuring the correctness of URI is left to the client code. If CAIRO_MIME_TYPE_URI is not present, but CAIRO_MIME_TYPE_JPEG or CAIRO_MIME_TYPE_PNG is specified, the corresponding data is Base64-encoded and emitted. filename : a filename for the SVG output (must be writable), NULL may be used to specify no output. This will generate a SVG surface that may be queried and used as a source, without generating a temporary file. width_in_points : width of the surface, in points (1 point == 1/72.0 inch) height_in_points : height of the surface, in points (1 point == 1/72.0 inch) Returns : a pointer to the newly created surface. The caller owns the surface and should call Cairo.Surface.Destroy when done with it. This function always returns a valid pointer, but it will return a pointer to a "nil" surface if an error such as out of memory occurs. You can use Cairo.Surface.Status to check for this. Since 1.2
