Why "BufferedImage image = ImageIO.read(new ByteArrayInputStream(imageBytes));" returns null value?

I'll bet you dollars to donuts that "instance.toString()" does not return anything remotely resembling what you seem to assume it returns.

Thanks for your response. Could you please help me to achieve the target?

Depends on what you intend to do. It looks like you're trying to convert a PDF to a (series of) images. I've never tried that, but I noticed that the com.lowagie.text.Image class has methods called getOriginalData and getOriginalType; those might be useful for that task.

If that's all you're trying to do, you might check out the PDFBox library, which has this functionality (amongst others).
 
Have you checked out Aspose?
