What is the JBIG2?
The JBIG2 software is that compression technology that is perfect for bi-level photos and images. In technical terms the JBIG2 software works by segregating the documents into areas and regions. Examples of such segments are the creation of areas of text, halftone regions and other image or data regions. The JBIG2 software will then use the arithmetic coding in the compression of the regions that is neither text nor halftone images. Technically speaking, the textual regions are those areas that are compressed by grouping the foreground pixels into symbols. The symbols are usually corresponding to the characters that are found in the document. The JBIG2 software also uses the lossy compression method and the lossless compression method. In some cases, the halftone images are compressed by converting the images into the grayscale appearance that compared the images with the patterns in the grayscale model. In the simplest explanations, the JBIG2 software will reduce files by substituting the texts with symbols.
How Does It Work?
The JBIG2 software works by identifying groups of pixels that are arranged in similar fashions. This type of action is conducted by the program to check if the variances and similarities in the appearance can be substituted with a single symbol or various symbols. The JBIG2 software will then create this table of symbols where it will be gathering the texts and words in. This compression methodology offers this great compression ratio that will work very well on those large files and document images. If you have used the JBIG2 software, you would often get this ratio of a hundred to one on the files.
Besides giving you this very large space to store other documents, the JBIG2 software will give you this flexible working environment. It has acted on compressing files from halftone images, text and simple binary image documents. The JBIG2 software also allows the user to work on compression of volumes. Additionally, another advantage by the program is the filter feature that will eventually allow the user to view the compressed files on any computer network. Plus, as it works with the lossy and lossless compression methods, your file will still have this output that is still workable and clear.
