Convert CAL to CUR

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 CUR file extension, short for Cursor Image, is a format used in Microsoft Windows for cursor icons. Its primary use is to display and manage custom cursor images, enhancing user interaction with graphical user interfaces. CUR files, a variant of ICO files, were introduced in early versions of Windows to enable animated and static cursor designs, elevating visual and functional user experiences. The structure typically contains image data, including multiple resolutions and color depths, which ensures adaptability across various display settings in Windows environments.
