WBMP, or Wireless Bitmap, is a monochrome graphics file format specifically designed for wireless devices, such as mobile phones and PDAs. It was introduced as part of the Wireless Application Protocol (WAP) standard to facilitate the display of simple images on limited display screens of early mobile devices. The format is highly optimized for low-bandwidth environments and supports only black and white colors to minimize data transmission requirements. WBMP files are compact and easy to process, making them ideal for the constrained resources of early wireless communications technology. WBMP played a crucial role in the early days of mobile web browsing by enabling basic graphical content on devices with minimal graphical capabilities.
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.
