The CAL file extension, known as CALS (Continuous Acquisition and Life-cycle Support) Type 1 Image, is a 1-bit black-and-white raster image format developed by the U.S. Department of Defense in the mid-1980s to standardize graphics data interchange for military documentation. It is primarily used for storing and sharing monochrome images while retaining orientation metadata. The format supports both uncompressed and compressed (using CCITT Group 4 compression) images.
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.
