• Constructor Details

  • FileImageOutputStream

  Constructs a FileImageOutputStream that will write to a given File.
  Parameters:
  f - a File to write to.
  Throws:
  [IllegalArgumentException](../../../../java.base/java/lang/IllegalArgumentException.html "class in java.lang") - if f isnull.
  [SecurityException](../../../../java.base/java/lang/SecurityException.html "class in java.lang") - if a security manager exists and does not allow write access to the file.
  [FileNotFoundException](../../../../java.base/java/io/FileNotFoundException.html "class in java.io") - if f does not denote a regular file or it cannot be opened for reading and writing for any other reason.
  [IOException](../../../../java.base/java/io/IOException.html "class in java.io") - if an I/O error occurs.

  • FileImageOutputStream

  Constructs a FileImageOutputStream that will write to a given RandomAccessFile.
  Parameters:
  raf - a RandomAccessFile to write to.
  Throws:
  [IllegalArgumentException](../../../../java.base/java/lang/IllegalArgumentException.html "class in java.lang") - if raf isnull.

• Method Details

  • seek

  public void seek​(long pos) throws IOException
  Sets the current stream position and resets the bit offset to 0. It is legal to seeking past the end of the file; anEOFException will be thrown only if a read is performed. The file length will not be increased until a write is performed.
  Parameters:
  pos - a long containing the desired file pointer position.
  Throws:
  [IndexOutOfBoundsException](../../../../java.base/java/lang/IndexOutOfBoundsException.html "class in java.lang") - if pos is smaller than the flushed position.
  [IOException](../../../../java.base/java/io/IOException.html "class in java.io") - if any other I/O error occurs.

  • finalize

  Finalizes this object prior to garbage collection. Theclose method is called to close any open input source. This method should not be called from application code.
  Overrides:
  [finalize](ImageInputStreamImpl.html#finalize%28%29) in class [ImageInputStreamImpl](ImageInputStreamImpl.html "class in javax.imageio.stream")
  Throws:
  [Throwable](../../../../java.base/java/lang/Throwable.html "class in java.lang") - if an error occurs during superclass finalization.
