Convert HEIC to CALS

The High Efficiency Image Container (HEIC) is a file extension used to store images and image sequences, leveraging the High Efficiency Image Format (HEIF). 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.

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.
