    • ASCII format.
    • Stores a monochrome bitmap as C language source code.
    • XBM is an acronym derived from X BitMap.
    • Developed in the 1980s at MIT.

Import & Export

  • Import["file.xbm"] imports an XBM file, returning an Image object.
  • Import["file.xbm",elem] imports the specified element from an XBM file.
  • The import format can be specified with Import["file","XBM"] or Import["file",{"XBM",elem,}].
  • Export["file.xbm",expr] exports graphics or any other expression as an image to XBM.
  • When exporting Wolfram Language graphics or arbitrary expressions, the resulting image has the same raster size as its displayed form.
  • Because XBM is a raster image format, all fonts are rasterized on export.
