Convert WBMP to RAS

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 Sun Raster file extension, also known as RAS, is a bitmap graphics file format developed by Sun Microsystems for use on their SunOS operating system. It supports black-and-white, grayscale, and color images with various pixel depths and includes simple Run-Length Encoding (RLE) compression. The format was widely used in UNIX-based systems and is supported by many imaging applications. The RAS format has largely been superseded by more modern formats but remains relevant for legacy systems and specific use cases.
