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 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 specified file.
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.
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
