The world of digital media is constantly changing. That makes any claim of being "a revolutionary breakthrough" suspect in our world. Yet JBIG2 is proving to be just that. This technology allows electronic documents to be compressed into file sizes that offer optimal speed in transmission over business networks, via wireless and e-mail, and on the World Wide Web. In fact, JBIG2 offers a first: the capacity to generate a scanned document whose file size matches the size of its corresponding text file. the high-level compression advantages of JBIG2 are being combined seamlessly into a technology that reduces an image with no loss of accuracy or quality.
A short story
As amazing as it seems, the idea of transmitting images over wire came into being before the Pony Express. Alexander Bain filed the first patent for image transmission via wire in 1843, some 17 years before the first Pony Express delivery in 1860. Bain's idea was realized by the end of the Civil War. By 1865, images were being transmitted over telegraph lines. (And the Pony Express had been defunct for three years.)
There are a number of file formats available for document transmission and storage, some more efficient than others. In the pages that follow, you'll see why file formats make a difference - and why JBIG2 is being heralded as a breakthrough format.
Why should you use JBIG2?
Here's the best part. JBIG2 is supported by PDF as a compression filter. This means you can create a JBIG2 compressed PDF file and any one with Adobe Acrobat 5.0 or greater can view the image. So most desktops already have a JBIG2 viewer installed.by the way it does compress well. I have found JBIG2 to compress 7 times better than Group 4 compression. An image uncompressed 1 meg was compressed in Tiff group 4 to 82k. JBIG2 was able to compress down to 12k you must know JBIG2 creates a symbol table. Usually text characters in the image. After the table is built redundant symbols can be eliminated. This can be done be creating a tolerance for lossy compression or exact for lossless compression
