This applet can generate and animate a realtime Mandelbrot fractal. This
applet is fully parametrized, so you can generate all kinds of Mandelbrot
fractal effects.

**********************************************************************

NECESSARY FILES.

Apart from an optional overlay image, the following 3 ".class" files 
must be uploaded: 

mandel.class
Lware.class
anfy.class

Plus, mandel.jar for speedy loading on recent browsers.

*********************************************************************

EXAMPLE.

Insert the <applet> tag in your html document as follows to add this applet
to your page (Comments after the ";" symbol are code explanations and
acceptable min/max values. They are not part of the applet language):


<applet archive="mandel.jar" code="mandel.class" width="300" height="300">

INSTRUCTIONS.


The following instructions describe how to change parameters:

Attempting to change the credits parameter will disable the applet.

To activate the reg parameters read the shareware registration notes.
In the "regcode" parameter, place the registration code you purchased
 from the author. If the code is correct and the applet is run from
the registered domain name, you can use "link" parameters to link to a URL
when the applet is "clicked".

If you set "regnewframe" to "YES", you can specify a specific frame location
for the reglink:

"_blank"  : To load the link in a new blank unnamed browser window.
"_self"   : To load the link into the same window the applet occupies.
"_parent" : To load the link into the immediate FRAMESET parent.
"_top"    : To load the link into the top body of the window.

You can also set a custom frame name, such as "myframe1".

With the "overimg" parameter you can specify the name of an image that will
be painted over the applet. The best options are transparent GIF images.
NOTE: Animated GIF images are supported, but will be animated only on 
latest browsers (Netscape 4 and Explorer 4 or newer).

With "overimgX" and "overimgY" you can center the image over the applet area.

The size of the applet is determined by the width and height tags.

The "res" parameter determines the resolution: with res=1 pixels are small,
but effect is slow. With res=8 pixels are too big but the effect is fast.
The optimum choices are 2-4.

Parameters for fractal generation: I don't place limits to values, and 
they can be positive or negative. Place values at your own risk.

The following parameters affect the applet actions depending on the positive
or negative values:

 XMin:  + scroll right,  - scroll left
 XMax:  + less width X,  - enlarge width X
 YMin:  + more height Y, - less height Y
 YMax:  + scroll down,   - scroll up

These descriptions are generalizations. You are free to experiment with 
a variety of values.

27 different palettes are available, just select the one you prefer for
your web page.
