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 infre
quently. 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 imme
diately, 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 win
dow. The default is 640x480 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 speci
fied file.

BUGS

There are many bugs and things that haven't been imple
mented. Many potential bugs are discussed in the README
file.

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 {
