Class javax.imageio.stream.ImageInputStream

Examples of javax.imageio.stream.ImageInputStream.reset()

javax.imageio.stream.ImageInputStream.reset()
Returns the stream pointer to its previous position, including the bit offset, at the time of the most recent unmatched call to mark.
Calls to reset without a corresponding call to mark have no effect.
An IOException will be thrown if the previous marked position lies in the discarded portion of the stream. @exception IOException if an I/O error occurs.
