Constructor Details

JFIFOutputStream

public JFIFOutputStream(ImageOutputStream out)
                 throws IOException

Throws:

IOException

JFIFOutputStream

public JFIFOutputStream(File imgFile)
                 throws IOException

Throws:

IOException

Method Details

getStreamPosition

public long getStreamPosition()
                       throws 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:

IOException

seek

public void seek(long newPosition)
          throws 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:

IOException

pushSegment

public void pushSegment(int marker)
                 throws IOException

Throws:

IOException

popSegment

public void popSegment()
                throws IOException

Throws:

IOException

getSegmentOffset

public long getSegmentOffset()
                      throws IOException

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

Throws:

IOException

getSegmentLength

public long getSegmentLength()
                      throws IOException

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

Throws:

IOException

finish

public void finish()
            throws IOException

Throws:

IOException

close

public void close()
           throws IOException

Specified by:

close in interface AutoCloseable

Specified by:

close in interface Closeable

Overrides:

close in class OutputStream

Throws:

IOException

write

public void write(byte[] b,
 int off,
 int len)
           throws 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 OutputStream

Throws:

IOException

write

public void write(int b)
           throws 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 OutputStream

Throws:

IOException
