X Windows Dump Image (.xwd)

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.

Continuous Acquisition and Life-cycle Support Type 1 Image (.cals)

The CALS (Continuous Acquisition and Life-cycle Support) Type 1 Image file format, developed by the United States Department of Defense in the mid-1980s, is a standard for storing raster (bit-mapped) image data, typically black-and-white. It ensures efficient data interchange and retention of orientation metadata. The format supports both uncompressed and compressed (using CCITT Group 4 compression) images. This standard was part of the broader CALS initiative aimed at improving electronic publishing and data management within the federal government.
