Convert CAL to XWD

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 XWD (X Windows Dump) file extension refers to an uncompressed bitmap image format used by the X Window System to store screen captures or "screen dumps" of windows or backgrounds. Developed by the X Consortium, it captures images of graphical user interfaces on UNIX and Linux platforms. The format, originating with X10 and later used in X11, is known for its large file sizes due to the lack of compression. XWD files are typically used for debugging and documentation purposes within the realm of computer graphics.
