Convert BMP to CAL

The BMP (Bitmap Image) file extension is a raster graphics format used primarily for storing digital images. Developed by Microsoft, BMP files retain high image quality due to their lack of compression, making them ideal for preserving detailed and colorful images. Introduced in the early days of Windows, BMP's simplicity and widespread compatibility have cemented its role in digital imaging, despite being superseded by more efficient formats in many applications.

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.
