About JBG (.JBG)
JBG stands for 'Joint Bi-level Image Experts Group,' a file format used for compressing black-and-white images using bi-level compression methods. It is mainly used in fax and document imaging applications to reduce file sizes while preserving text clarity. This format is less common today but was once popular due to its efficiency in handling scanned documents. Interestingly, JBG is closely related to the JBIG standard, which improved compression performance for bi-level images.
Technical Details
The JBG format uses bi-level image compression algorithms that encode pixels as either black or white, making it ideal for text and line art. It employs entropy coding techniques to reduce redundancy and achieve smaller file sizes without sacrificing detail. JBG is based on the JBIG (Joint Bi-level Image Experts Group) standard, which was finalized in the mid-1990s to address limitations of older methods like CCITT Group 4. Its compression approach is distinct from JPEG, which is used for color and grayscale images.
Additional Information & Use Cases
JBG files are typically used in environments where storage space is limited, such as fax transmissions and archival of scanned documents. They support lossless compression, meaning the image quality remains intact even after compression. Despite its niche use, JBG paved the way for more advanced compression standards in document imaging. The format's development was driven by the need to optimize transmission speeds over slow networks in the early days of digital communication.
