Convert CALS to JPE

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 JPE file extension stands for Joint Photographic Experts Group. It is a widely used image format known for its efficient compression and high quality, making it ideal for digital photography and web use. Originating in the late 1980s, the JPE format was developed to enable the effective storage and transmission of photographic images. Its primary purpose is to reduce file size without significantly compromising image quality, thereby optimizing storage and facilitating faster file transfers in computer technology contexts.
