NAME
wmMand - Dockable Mandelbrot browser
SYNOPSIS
wmMand [-h, --help] [-z, --zoom <factor>] [-i, --iterations <number>]
[-l, --largesize <number>] [-d, --delayzoom <number>] [-x, -xv]
DESCRIPTION
wmMand is a dockable Mandelbrot fractal browser or explorer. The window
initially comes up with the whole Mandelbrot set in view. The mouse
buttons can be used to zoom into or out of the set. Use the left mouse
button to zoom in, and the right button to zoom out. The view window is
recentered to a point roughly half way from the center to the point
clicked. You can also zoom in and out without recentering using a
scrollwheel.
Pressing the middle mouse button or ’b’ on the keyboard brings up a
button bar that allows the user to change color tables (button ’C’ on
the bar), change the maximum number of iterations (the button with
numbers in it), reset to initial view (button ’R’), and show a larger
version of the image with imagemagick’s "display" or "xv" (button ’V’).
The ’M’ button is currently unused. When clicking on buttons that
iterate through a range of values (such as ’C’ and the "iterations"
button), the left button moves in one direction and the right moves in
the other.
When the mouse is over the window, pressing certain keys on the
keyboard will also have some effects, as follows:
arrow and NumberPad keys
Move the view based on the zoom factor
z, +, NumberPad 5
Zoom in
o, -, NumberPad 0
Zoom out
c Cycle colour table (palette)
v View large image with ImageMagick’s "display" program (or "xv"
if started with the -x or --xv command line option)
r Reset to initial view
i Change max iterations (double in value up to 2048, then back to
64)
b Show/hide button bar
x View current view with XaoS (if installed), using the size given
by the largesize value. Note that due to rounding off at high
levels of zoom the image displayed may be somewhat offset. Also
differences in the palette can be striking.
q Attempt to "ungrab" the mouse if something bad happens and it
won’t release automatically
A higher number of iterations will allow you to look deeper in the
fractal. However, if you feel yourself limited by wmMand, check out the
’XaoS’ program by Jan Hubicka (http://xaos.sourceforge.net). Personally
I think they complement each other nicely.
OPTIONS
-h, --help
Display list of command-line options.
-z, --zoom <factor>
Set zoom factor. Default is 1.2.
-i, --iterations <number>
Set initial maximum iterations (default 256). Possible values
are 64, 128, 256, 512, 1024 or 2048.
-l, --largesize <number>
Set the size of the large image displayed. The large image is
always square, so only one number is required. Default is 540.
-d, --delayzoom <number>
Set the amount of delay when autozooming. The higher the number,
the greater the delay between updates. Default is 10.
-x, -xv
Use the program "xv" instead of "display" to view the large
fractal image. Please note that the resulting image will be
exactly the same either way.
BUGS
It has been known to "swallow" the pointer,and not release it. This can
usually be rectified by pressing ’q’ or ’ESC’, or the combination CTRL-
ALT-’/’ (the numberpad divide key), unless that option has been
disabled on your system.
TODO
Enable ’M’ button to change fractal type. Use antialiasing for the
large image (and maybe the small)
