 XFRACTINT(1)                                                   XFRACTINT(1)

      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.

           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.

           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.

           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

           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.

           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       {
