39.        --  attached to a surface (see Cairo.Surface.Set_Mime_Data) when it is

40.        --  used as a source pattern for drawing on this surface:

41.        --  CAIRO_MIME_TYPE_JPEG, CAIRO_MIME_TYPE_PNG, CAIRO_MIME_TYPE_URI. If any

42.        --  of them is specified, the SVG backend emits a href with the content of

43.        --  MIME data instead of a surface snapshot (PNG, Base64-encoded) in the

44.        --  corresponding image tag.

45.        --

46.        --  The unofficial MIME type CAIRO_MIME_TYPE_URI is examined first. If

47.        --  present, the URI is emitted as is: assuring the correctness of URI is

48.        --  left to the client code.

49.        --  If CAIRO_MIME_TYPE_URI is not present, but CAIRO_MIME_TYPE_JPEG or

50.        --  CAIRO_MIME_TYPE_PNG is specified, the corresponding data is

51.        --  Base64-encoded and emitted.

54.        --   a filename for the SVG output (must be writable), NULL may be used to

55.        --   specify no output. This will generate a SVG surface that may be queried

56.        --   and used as a source, without generating a temporary file.

57.        --  width_in_points :

58.        --   width of the surface, in points (1 point == 1/72.0 inch)

61.        --  Returns :

62.        --   a pointer to the newly created surface. The caller owns the surface and

63.        --   should call Cairo.Surface.Destroy when done with it. This function

64.        --   always returns a valid pointer, but it will return a pointer to a "nil"

65.        --   surface if an error such as out of memory occurs. You can use

66.        --   Cairo.Surface.Status to check for this.
