Continuous Acquisition and Life-cycle Support Type 1 Image (.cal)

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.

Developed by the Moving Picture Experts Group (MPEG) and introduced in 2015, HEIC files are acclaimed for their superior compression efficiency, which allows for high-quality images at smaller file sizes. This format is widely used in modern digital devices, including smartphones and cameras, to optimize storage capacity without compromising image quality. It supports advanced features such as live photos, burst photo sequences, and transparent images, making it integral for contemporary digital imaging solutions.
