The JNG format expertly blends JPEG's compression with PNG's transparency. Developed by the PNG Development Group, it's a member of the MNG family, designed for embedding lossy JPEG images in animations. While JNG files are more compact, they may exhibit typical JPEG compression artifacts.
The CALS (Continuous Acquisition and Life-cycle Support) Type 1 Image file format, developed by the United States Department of Defense in the mid-1980s, is a standard for storing raster (bit-mapped) image data, typically black-and-white. It ensures efficient data interchange and retention of orientation metadata. The format supports both uncompressed and compressed (using CCITT Group 4 compression) images. This standard was part of the broader CALS initiative aimed at improving electronic publishing and data management within the federal government.
