bitmap-stream

Arguments: drawable

Returns the bitmap-stream most recently used by a drawable, or nil if none has been used. This function is not setf'able; the bitmap-stream is created automatically when the use-bitmap-stream property is turned on. Setting use-bitmap-stream to nil disassociates any bitmap-stream from a drawable, although this function will still return the now-unused bitmap-stream.

Thus, if use-bitmap-stream has been turned on and then off, then the leftover bitmap-stream will still be returned. Therefore, an application should not assume that a drawable is currently using a bitmap stream simply because bitmap-stream returns true. Call use-bitmap-stream instead to determine if one is currently being used.
