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

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.

JPEG 2000 Compound Image File Format (.jpm)

The JPM file extension, integral to the JPEG 2000 image coding system, is tailored for document imaging using the Mixed Raster Content model. It supports multi-page, layered images and provides superior compression and image quality through wavelet-based methods. Despite its technical benefits, including support for both lossy and lossless compression, its adoption is limited due to complexity and the requirement for specialized software.
