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''.
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.
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.
This sets the size and position of the image window.
The default is 640x480 pixels.
Indicates that xfractint should share the current
colormap. That is, xfractint uses as many colors as
possible, but doesn't modify the colormap.
Uses simpler keyboard handling. Use this flag if you
wish to debug xfractint with gdb, or else you may get
"(gdb)" repeated infinitely.
Sets variable xxx to value yyy. See the online
documentation for more details on the possible

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
F1 to F10 Shift-1 to Shift-0
