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.
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
