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.
The Portable Network Graphics (PNG) file extension, established in 1996, serves as a widely-used raster graphics format that supports lossless data compression. Initially developed as a superior, patent-free replacement for the GIF format, PNG is prevalent in the IT industry for web design, digital photography, and complex graphics due to its capability to handle detailed images with transparent backgrounds and its extensive color range. Known for maintaining high-quality visuals without increasing file size significantly, PNG remains an indispensable tool in professional digital imaging and web development.
