Got Java code.

The below Java code helps to get the TIFF stream from PDF stream  :

java.io.File tiffFile=null;

try{	
       	tiffFile =java.io.File.createTempFile("TiffFile",".TIFF");
		
		java.io.FileInputStream fis=new java.io.FileInputStream(tiffFile);
				
		org.apache.pdfbox.pdmodel.PDDocument document = null;
		document = org.apache.pdfbox.pdmodel.PDDocument.load(Base64Util.decodeToByteArray(FileData));
		org.apache.pdfbox.rendering.PDFRenderer pdfRenderer = new org.apache.pdfbox.rendering.PDFRenderer(document);
		int pageCount=document.getPages().getCount();
		int pageCounter=0;
		java.util.ArrayList<java.awt.image.BufferedImage> bImgList=new java.util.ArrayList<java.awt.image.BufferedImage>();

		for(pageCounter=0;pageCounter<pageCount;++pageCounter)
		{
			java.awt.image.BufferedImage bim = pdfRenderer.renderImageWithDPI(pageCounter, 196, org.apache.pdfbox.rendering.ImageType.BINARY);
			bImgList.add(bim);
		}

		java.util.Iterator<javax.imageio.ImageWriter> writers=javax.imageio.ImageIO.getImageWritersByFormatName("TIFF");
		javax.imageio.ImageWriter imageWriter = writers.next();
		javax.imageio.ImageWriteParam param = imageWriter.getDefaultWriteParam();
		param.setTilingMode(javax.imageio.ImageWriteParam.MODE_DEFAULT);
		//Compression Mode
		param.setCompressionMode(javax.imageio.ImageWriteParam.MODE_EXPLICIT);
		param.setCompressionType("CCITT T.4");
		
		javax.imageio.stream.ImageOutputStream ios = javax.imageio.ImageIO.createImageOutputStream(tiffFile);
		imageWriter.setOutput(ios);
		imageWriter.prepareWriteSequence(null);
		
		
		for (java.awt.image.BufferedImage image : bImgList)
		{
			
			javax.imageio.metadata.IIOMetadata metadata = imageWriter.getDefaultImageMetadata(new javax.imageio.ImageTypeSpecifier(image), param);		
			imageWriter.writeToSequence(new javax.imageio.IIOImage(image, null, metadata), param);
			
		}
		java.io.ByteArrayOutputStream baos=new java.io.ByteArrayOutputStream();
		
		int bt;
		while((bt=fis.read())!=-1)
			{
			baos.write(bt);
			}
			byte[] filebteary= baos.toByteArray();
			EBDR=Base64Util.encodeToString(filebteary);
			
		imageWriter.endWriteSequence();
		imageWriter.dispose();
		fis.close();
		ios.flush();
		ios.close();
        document.close();
  		baos.close();
		
		
    }
catch(Exception e)
{
  e.printStackTrace();
}

finally
{
  tiffFile.delete();
}

The function can be prepared with this Java code and use.

If there is any best solution other than this, please post here.

Thanks.
