  • Export exports graphics or any other expression as an image to XBM.
  • Export creates an XBM image with the same image size as the displayed form of .
  • Because XBM is a raster image format, all fonts are rasterized on export.
  • Import imports the specified element from an XBM file.
  • Import imports multiple elements.
  • Export creates an XBM file by treating expr as specifying element elem.
  • Export treats each as specifying the corresponding .
  • Export exports expr with the specified option elements taken to have the specified values.
  • Export uses rules to specify the elements to be exported.
