Convert XBM to WBMP

The XBM (X11 Bitmap Graphic) file extension is a plain-text binary file format historically used in the X Window System to store monochrome bitmap images. Its primary use is for defining small, simple graphics such as icons and cursors. Originating from the 1980s, XBM files enable the inclusion of image data directly in C source code, facilitating easy integration and compilation within applications. While their use has declined with the advent of more advanced graphics formats, XBMs remain relevant for legacy systems and specific low-resource environments.

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.
