Constructor Details
- SubImageInputStream
  
  public SubImageInputStream(ImageInputStream pStream, long pLength) throws IOException
  
  Creates a ImageInputStream, reading up to a maximum number of bytes from the underlying stream.
  
  Parameters:
  
  pStream - the underlying stream
  
  pLength - the maximum length to read from the stream. Note that pStream may contain less than this maximum number of bytes.
  
  Throws:
  
  IOException - if pStream's position can't be determined.
  
  IllegalArgumentException - if pStream == null or pLength < 0
