  The X utilites read and write MIFF images.  You can find filters to
  convert to and from the MIFF format in this directory.  

  To compile, type

    xmkmf
    make

  Two examples of using a filter follow:

    GIFtoMIFF image.gif - | display -

      or

    TIFFtoMIFF image.tiff image.miff
    display image.miff

  The TIFFtoMIFF and MIFFtoTIFF filters require Sam Leffler's TIFF
  software available via FTP as sgi.com:graphics/tiff/v2.4.tar.Z.

  The PPMtoMIFF and MIFFtoPPM filters require Jef Poskanzer's PBMPLUS
  software available via FTP as export.lcs.mit.edu:contrib/pbmplus.tar.Z.

  To succesfully compile the PPMtoMIFF and MIFFtoPPM filters, first compile
  the pbmplus routines.  Next copy pbmplus.h, pbm/pbm.h, pgm/pgm.h, 
  ppm/ppm.h, and pnm/pnm.h to /usr/local/include.  Change

    #include "../pbmplus.h"

  to

    #include "pbmplus.h"

  in /usr/local/include/pbm.h.

  Next copy pbm/libpbm.a, pgm/libpgm.a, ppm/libppm.a, and pnm/libpnm.a
  to /usr/local/lib.

  Finally, type 

    make PPMtoMIFF
    make MIFFtoPPM

 Use MTVtoMIFF to convert Rayshade images to MIFF.  The filter can accept
 multiple Rayshade animation frames from a single MTV image file.
