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.

Pyramid Encoded TIFF (.ptif)

The PTIF (Pyramid Encoded TIFF) file format, developed by Image Magick, is a specialized variant of the TIFF image format designed to store multiple resolutions of the same image within a single file. This enables efficient zooming and panning in applications without losing image quality. PTIF files are commonly used in geospatial imaging, remote sensing, and medical imaging due to their ability to handle large, high-resolution images efficiently. The format was introduced to address the need for handling large image datasets more effectively in these fields.
