Constructor Detail

JFIFOutputStream

public JFIFOutputStream(javax.imageio.stream.ImageOutputStream out)
                 throws java.io.IOException

Throws:

java.io.IOException

JFIFOutputStream

public JFIFOutputStream(java.io.File imgFile)
                 throws java.io.IOException

Throws:

java.io.IOException

Method Detail

getStreamPosition

public long getStreamPosition()
                       throws java.io.IOException

Gets the position relative to the beginning of the IFF output stream.

Usually this value is equal to the stream position of the underlying ImageOutputStream, but can be larger if the underlying stream already contained data.

Returns:

The relative stream position.

Throws:

java.io.IOException

seek

public void seek(long newPosition)
          throws java.io.IOException

Seeks relative to the beginning of the IFF output stream.

Usually this equal to seeking in the underlying ImageOutputStream, but can be different if the underlying stream already contained data.

Throws:

java.io.IOException

pushSegment

public void pushSegment(int marker)
                 throws java.io.IOException

Throws:

java.io.IOException

popSegment

public void popSegment()
                throws java.io.IOException

Throws:

java.io.IOException

getSegmentOffset

public long getSegmentOffset()
                      throws java.io.IOException

Returns the offset of the current segment or -1 if none has been pushed.

Throws:

java.io.IOException

getSegmentLength

public long getSegmentLength()
                      throws java.io.IOException

Returns the length of the current segment or -1 if none has been pushed.

Throws:

java.io.IOException

finish

public void finish()
            throws java.io.IOException

Throws:

java.io.IOException

close

public void close()
           throws java.io.IOException

Specified by:

close in interface java.io.Closeable

Overrides:

close in class java.io.OutputStream

Throws:

java.io.IOException

write

public void write(byte[] b,
                  int off,
                  int len)
           throws java.io.IOException

Writes stuffed or non-stuffed bytes to the underlying output stream. Bytes are stuffed, if the stream is not currently in a segment.

Overrides:

write in class java.io.OutputStream

Throws:

java.io.IOException

write

public void write(int b)
           throws java.io.IOException

Writes a stuffed or non-stuffed byte to the underlying output stream. Bytes are stuffed, if the stream is not currently in a segment.

Specified by:

write in class java.io.OutputStream

Throws:

java.io.IOException
