  23.       An abstraction used by QImageDecoder.
  24.  
  25.       A QImageConsumer consumes information    about changes to the
  26.       QImage maintained by a QImageDecoder.    It represents the a
  27.       view of the image which the decoder produces.

  50.       not have been    decoded    by then, in which case the frame
  51.       should not be    displayed until    it is complete.    A value    of -1
  52.       (the assumed default)    indicates that the image should    be
  53.       diplayed even    while it is only partially loaded.
