Convert JBIG to X AVS

The JBIG (Joint Bi-level Image Group) file extension, standardized as ISO/IEC 11544 and ITU-T T.82 in 1993, is a lossless image compression format primarily used for binary images, such as those in fax transmissions. Developed by the Joint Bi-level Image Experts Group, JBIG offers significant compression efficiency over previous standards, achieving up to 50% better compression than Fax Group 4. Its history dates back to 1988 when ISO and CCITT collaborated to create a unified standard for bi-level image coding.

The X file extension, also known as Application Visualization System X Image, is used for storing high-quality, true-color images with transparency. Developed by Stardent Computer for UNIX systems, it supports 32 bits per pixel, allowing for over 16,7 million colors with an alpha channel for transparency. This format is particularly valuable in scientific visualization and complex data representation. Despite newer formats, its uncompressed nature ensures image integrity without compression-related degradation.
