3.6, and WebKit-based browsers. There is a strong indication that Chromium (and therefore, also, Google Chrome) does not support XBM. Documentation for Opera 2.12 and 6.0 indicates that XBM was at least previously supported. Some image viewers/converters, e.g., XnView, FFmpeg and IrfanView, support XBM. A 48×48 XBM can be converted to Ikon and eventually X-Face with Netpbm tools. Despite having been superseded by the XPM format, XBM is still used by some modern but lightweight window managers like Openbox to define simple button images in a window's title bar, such as the iconify/minimize, restore, and maximize buttons. XBM is also used in embedded processing (microControllers) to display Icons used in GUIs. ImageMagick supports converting images both to and from XBM. GIMP may be used to create or modify images using the XBM format, and also supports converting images to and from the XBM format.
