Yes Balasubramanian,
I think we cannot edit the IPTC datas on image file. We can only extract the datas and use it for other purposes. I dont think, but it can be available on the net.
When going with the thrid party components(Extractor), I dont think it is not that much easier to do all the image operations. You can just get the File stream structure of the JPEG file (it will be available on the net for
Joint Photographic Experts Group). And use that Stream object for extracting / editing the meta data information.
I will also search or do some R & D works regarding this and let u know before this evening.
thanks
