Convert CAL to JPM

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 JPM file extension stands for JPEG 2000 Compound Image File Format. It is used for storing multiple images and graphics, incorporating JPEG 2000 compression to achieve high-quality visuals with reduced file sizes. JPM files are particularly useful in scenarios that require efficient storage and handling of complex image data, such as digital archiving, medical imaging, and document management. Developed as part of the broader JPEG 2000 standard, the JPM format was introduced to enhance image quality and compression over its predecessor, JPEG. Its support for transparency, layers, and metadata makes it a versatile choice in professional IT and imaging applications.
