This applet can simulate water wavings over any GIF or JPG image.This applet
is fully parametrized, so you can generate all many variations of water
wavings.

The animation fish.gif is a courtesy of Paolo Sioli / Digibit.

The following 3 ".class" files must be uploaded: AnWater.class, Lware.class
and anfy class.

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):

The following instructions detail how to change parameters:

The images (GIF and/or JPG) can be of any size, but all image dimensions must
be identical.

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 displayed as 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 GIF/JPG image can be of any size. If res=1, remember to place the exact
size of image in "width" and "height" tags. If res=2, place double values,
if res=3 triple values etc.
(In fact, res is a sort of zoomer).

You can enable or disable the light shade calculation with "light" parameter.
The effect without light calculations is faster, but less realistic.

If you set to "YES" the "autodesign" parameter, an automatic slideshow of the
effects will be executed, and the next parameters are ignored.

If you set to "NO" the autodesign, you have to configure effects manually:

The "density" parameter (2 .. 6) controls the density if fluid. Lower values
mean more fluid liquid, so waves end quickly. Higher values cause a slower
decadence of the waves.

You can insert up to 2 fishes, with "fishnum" parameter.

Other effects are: cross, rain and srain.

Set the parameter "cross" to YES to activate this strange effect.
The "crossfactor" parameter works as "timer" between one cross and another.
By setting "crossfactor" to 0, a new cross will appear every frame.
Higher values mean more distance between one cross and another.

The "rainsize" will determine a circular rain. If it is set to zero= no
rain. Values higher or equal to 1 will generate rain.
To control it use "rainfactor" as seen for "crossfactor".

The "srainsize" and "srainfactor" parameters work the same as "rainsize" and
"rainfactor", but generate square rain.

You can enable more than one effect at the same time.

Another option is to enable the "fixdrop" parameter setting it to "YES",
it will generate drops only at the fixed X and Y positions specified
with the "fixdropX" and "fixdropY" parameters.
The size and frequency of these drops are determined by the parameters
named "fixdropS" and "fixdropF".
