Create RTF image output stream.

Parameters:

writer - the stream to write the converted image

imageType - target image type

Method Details

writeHex

protected void writeHex(byte b)
                 throws IOException

Write hexadecimal string.

Parameters:

b - a byte

Throws:

IOException - when IO error occurred

write

public void write(int b)
           throws IOException

Writes the specified byte to this RTF image output stream.

Specified by:

write in class OutputStream

Parameters:

b - the byte to be written.

Throws:

IOException - if an I/O error occurs. In particular, an IOException may be thrown if the output stream has been closed.

write

 int off,
 int len)
           throws IOException

Writes len bytes from the specified byte array starting at offset off to this byte RTF image output stream.

Overrides:

write in class OutputStream

Parameters:

b - the data.

off - the start offset in the data.

len - the number of bytes to write.

Throws:

IOException - if an I/O error occurs. In particular, an IOException may be thrown if the output stream has been closed.

getTotalWrittenChars

public long getTotalWrittenChars()

Return total characters has been written.

Returns:

the total written characters

close

public void close()
           throws IOException
