Extracting jpg images from an " old style JPEG-in-TIFF" type image

TIFF(Tagged Image File Format) is an image decoding format where multiple related jpeg images are tagged under a same file and saved in a single file in a decoded format. Java provides a way of decoding these images and extract the decoded jpg files using it's Java Advanced Imaging (JAI) package, however before the decoding format for TIFF was standardized the image packaging was done simply by binary files using some tagging code between them. Java declared that it is not interested in providing a solution for decoding the old-style nonstandard TIFF file. I recently came across a situation where the client had TIFF images in the" old style JPEG-in-TIFF" format. Hence I had to discover a solution to decode them.
