NAME
xfractint - fractal generation program
SYNOPSIS
xfractint [options] [; comments]
DESCRIPTION
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''.
OPTIONS
-display display_name
Specifies the X11 display to use.
-onroot
Indicates the resulting images should appear on the root window.
Note: rubberband zoom boxes don't work on the root window.
-private
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.
-slowdisplay
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.
-simple
Uses simpler keyboard handling. Use this flag if you wish to
debug xfractint with gdb, or else you may get "(gdb)" repeated
infinitely.
xxx=yyy
Sets variable xxx to value yyy. See the online documentation for
more details on the possible variables.
@filename
Loads parameters from the specified file.
@filename/groupname
Reads a named group of parameters from the specified file.
-psviewer
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.
-ctrlwindow
Allows the user to have a separate control window similar to the
ncurses interface.
-font
Loads the selected font.
-fontbold
Loads the selected bold font.
BUGS
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.

20.04
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
