       xfractint - fractal generation program


       xfractint [options] [; comments]


       Xfractint draws a wide variety of fractals.  Xfractint is a port of the
       IBM PC program fractint.   Xfractint  has  online  documentation  which
       should  be  referenced  for  most operation information.  Note that the
       online documentation is from fractint, and does not  always  accurately
       describe  xfractint.  A text version of the online documentation can be
       generated by running ``make doc''.


       -display display_name
              Specifies the X11 display to use.

              Indicates the resulting images should appear on the root window.
              Note: rubberband zoom boxes don't work on the root window.

              Indicates  that  xfractint  should  allocate  as  many colors as
              possible in a private colormap.  Normally xfractint will use 128
              colors;  this flag will let you use all 256, but may mess up the
              colors in other windows.  This is not necessary if you are using
              greater than 8-bit color.

              Indicates  that the machine has a slow display, so the scrolling
              window  should  be  updated  infrequently.   Use  this  flag  if
              xfractint hangs on the title screen.

       -fast  Indicates  that  xfractint  should  use the faster drawing mode.
              Instead of drawing each pixel immediately, xfractint  will  save
              up   pixels  and  then  refresh  the  screen  every  5  seconds.
              Depending on your X implementation, this may make drawing  twice
              as fast.

       -disk  Use disk video.  That is, generate the picture in memory instead
              of to the screen.  The resulting picture can be saved as  a  gif
              file or printer file.

       -fixcolors num
              Specifies  the  number  of colors to use.  This number must be a
              power of two.  Also, this  number  can't  be  greater  than  the
              number of colors available.  And, it can't be greater than 256.

       -geometry WxH[{+-X}{+-Y}]
              This  sets  the  size  and  position  of  the image window.  The
              default is 800x600 pixels.

       -share Indicates that xfractint  should  share  the  current  colormap.
              That  is, xfractint uses as many colors as possible, but doesn't
              modify the colormap.  This is not necessary  with  greater  than
              8-bit colors.

              Uses  simpler  keyboard  handling.  Use this flag if you wish to
              debug xfractint with gdb, or else you may get  "(gdb)"  repeated

              Sets  variable  xxx  to value yyy.  See the online documentation
              for more details on the possible variables.

              Loads parameters from the specified file.

              Reads a named group of parameters from the specified file.

              Allows the user to change the default  postscript  viewer.   The
              viewer  is called when the user prints an image with ctrl-p. The
              default viewer is gv.

              Allows the user to have a separate control window similar to the
              ncurses interface.

       -font  Loads the selected font.

              Loads the selected bold font.


       There are many bugs and things that haven't been implemented.

       Boundary tracing sometimes locks up.

       Passes=2 has problems??

       Symmetry that is offset slightly doesn't always complete the image.

       The top of the help screens are messed up.  Starting your xterm with
              -geometry 80x25 fixes this.

       Xfractint  uses  a  bizarre  (to  Unix  users) user interface which was
       directly  copied  from  the  IBM  version.   If  you  don't  have   the
       appropriate keys, use the following key mappings:
       IBM             Unix
       F1 to F10       Shift-1 to Shift-0
       INSERT          I
       DELETE          D
       PAGE_UP         U
       PAGE_DOWN       N
       LEFT_ARROW      H
       RIGHT_ARROW     L
       UP_ARROW        K
       DOWN_ARROW      J
       HOME            O
       END             E
       CTL_PLUS        }
       CTL_MINUS       {
