public PDCcitt(PDStream ccitt) 
{
        super(ccitt, "tiff");
}

Standard constructor.

Parameters:

ccitt - The PDStream that already contains all ccitt information.

 public PDCcitt(PDDocument doc,
    RandomAccess raf) throws IOException 
{
        super( new PDStream(doc),"tiff");
        // super( new PDStream( doc, null, true ), "tiff" );
        COSDictionary decodeParms = new COSDictionary();
        COSDictionary dic = getCOSStream();
        extractFromTiff(raf, getCOSStream().createFilteredStream(),decodeParms);
        dic.setItem( COSName.FILTER, COSName.CCITTFAX_DECODE);
        dic.setItem( COSName.SUBTYPE, COSName.IMAGE);
        dic.setItem( COSName.TYPE, COSName.getPDFName( "XObject" ) );
        dic.setItem( "DecodeParms", decodeParms);
        setBitsPerComponent( 1 );
        setColorSpace( new PDDeviceGray() );
        setWidth( decodeParms.getInt("Columns") );
        setHeight( decodeParms.getInt("Rows") );
}

Construct from a tiff file.

Parameters:

doc - The document to create the image as part of.

raf - The random access TIFF file which contains a suitable CCITT compressed image

Throws:

IOException - If there is an error reading the tiff data.

 public BufferedImage getRGBImage() throws IOException 
{
        BufferedImage retval = null;
        InputStream tiff = new TiffWrapper(
                getPDStream().getPartiallyFilteredStream( FAX_FILTERS ),
                getCOSStream());
        try 
        {
            retval = ImageIO.read(tiff);
        }
        catch (Exception e)
        {
            log.error(e, e);
        } 
        finally 
        {
            if (tiff != null)
            {
                tiff.close();
            }
        }
        return retval;
}

Returns an image of the CCITT Fax, or null if TIFFs are not supported. (Requires additional JAI Image filters ) {@inheritDoc}

 public  void write2OutputStream(OutputStream out) throws IOException 
{
        InputStream data = new TiffWrapper(getPDStream().getPartiallyFilteredStream( FAX_FILTERS ),getCOSStream());
        byte[] buf = new byte[1024];
        int amountRead = -1;
        while( (amountRead = data.read( buf )) != -1 )
        {
            out.write( buf, 0, amountRead );
        }
}

This writes a tiff to out. {@inheritDoc}
