The MONO file extension stands for "Monochrome Bitmap" and is used for storing raw bi-level bitmap images, which are essentially black-and-white images without any color or grayscale. This format is primarily utilized in applications requiring simple, high-contrast images, such as fax transmissions and certain types of document scanning. The MONO format, characterized by its least-significant-byte first order, has been supported by various image processing tools. Its history traces back to early bitmap graphics needs, emphasizing simplicity and efficiency in image storage and processing.
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.
