      xmorph is a digital image warping and dissolving program, also known
      as a "morphing" program.  It runs under the X Window System.  The
      primary use of xmorph is to generate and modify meshes which control
      the shape of an image.  xmorph also has the capacity to dissolve
      images together, and to generate a sequence of warped and dissolved
      images.  When this sequence is made into a movie, it is called a

      morph is a morphing program with no graphical user interface.  morph
      performs image warping and dissolving but provides no means to create
      or modify meshes.  The intent is to use morph after meshes have
      already been generated with xmorph. Since morph has no GUI, it can be
      run as a background job and can be distributed over many machines or
      processes.  This parallelization of the task can significanly speed up
      the image processing.  morph can run on machines which have no display
      whatsoever, and is therefore very portable.

      Both xmorph and morph use a library called libmorph which can be used
      separately in the creation of other morphing programs.

      If imgfile names are provided on the command line, then those images
      are loaded in.  Otherwise, xmorph generates images to be used in lieu
      of images provided by the user.  Images may be loaded from menus
      within xmorph.  xmorph has built-in help pages that answer questions
      about the details of its use.  Run xmorph and look at the online help
      for more information.

      -start srcimgfile
           Read the srcimgfile as the "source" image.

      -finish destimgfile
           Read the destimgfile as the "destination" image.

      -src srcmeshfile
           Read the srcmeshfile as the "source" mesh.

      -dst destmeshfile
           Read the destimgfile as the "destination" mesh.

      -out outimgfile
           Write the the output image to outimgfile .

      -mt morphtween
           Use morphtween as the warping tween parameter.  Values are from 0
           to 1.  0 means that the shape of the output is according to the
           source mesh.  1 means that the shape is according to the
           destination mesh.  Default value is 0.

      -dt dissolvetween
           Use dissolvetween as the dissolve tween parameter.  Values are
           from 0 to 1.  0 means that the image of the output is according
           to the source image.  1 means that the image is according to the
           destination image.  Negative values indicate that a sigmoid
           sharpening function is to be applied to make the dissolving more
           concentrated to values near 0.5.  The idea is that the
           dissolvetween value should be the negative of the morphtween
           value in order to have the dissolve be more rapid during middle
           values of the warp tween parameter, and less rapid otherwise.
           This makes the morph more visually acceptable.  Default value is

      xmorph is NOT a tool for making movies.  xmorph is intended to be used
      with OTHER tools for editting movies in the digital domain.  I do not
      intend to add movie making abilities to xmorph.  Here is a brief
      explanation of how to make a movie from the images generated by
      xmorph: xmorph uses the TrueVision Targa (TGA) image file format.  You
      can use PBMplus, netpbm, ImageMagick or some other program to convert
      Targa to other still image formats.  (This will be necessary if, for
      example, you use the Berkeley MPEG encoder or want to make an animated
      GIF.) See, e.g.,  Use another
      program, such as Berkeley's mpeg_encode, or SGI's dmconvert, or
      whirlgif to turn the sequence of images that xmorph created into a
      single animation.  See, e.g., ftp://mm-  Use another program,
      such as mpeg_play, xanim or movieplayer, to view the animation.  See,
      e.g.,  There
      are plenty of other programs available for viewing movies.

      The only image file type currently supported is Truevision Targa (TGA)
      but xmorph will load any type of Targa, such as 8-bit, 15-bit, or 16-
      bit colormapped or grayscale; 24-bit or 32-bit true color (with or
      without alpha channel);  run-length encoded or uncompressed.  Some
      versions of the program "xv" can not read xmorph's TGA image files.
      This is a bug in "xv", not in xmorph.  Use image conversion programs
      (such as those listed in the SEE ALSO section) to convert to and from
      TGA image files for use with xmorph and morph . Report bugs to
