Convert SR to WBMP

The Sun Raster (SR) file extension, is a raster graphics file format developed by Sun Microsystems for use on their SunOS operating system. This format, which stores black-and-white, grayscale, and color bitmapped data, was widely used in UNIX-based systems and supported by various imaging applications. The Sun Raster format includes a header, an optional color map, and the bitmapped image data. Although it does not support transparency, it remains a simple and widely distributed bitmap format.

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.
