           Anfy Snow - Copyright (C) by Fabio Ciucci 1999


INTRODUCTION.

This applet visualises realistic snow flakes as a layer over a selected 
image, preferably the one with snow already present on the ground. This 
looks more natural.

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

NECESSARY FUILES

Apart from the background and overlay images, the following .class files
 must be uploaded: 

ansnow.class
Lware.class

Optionally, you may want to upload ansnow.jar for speedy loading on 
recent browsers.

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

EXAMPLE.

PARAMETER DESCRIPTIONS

The following instructions describe the meaning of the available 
parameters for this applet:

[Specify the applet and its size]

<applet archive="ansnow.jar" code="ansnow.class" width="320" height="208">

The size of the applet is determined by width and height tags, which should
be same as the background image size.

[Credit parameter]

<param name="credits" value="Applet by Fabio Ciucci (www.anfyteam.com)">

Attempting to alter the "credits" parameter will disable the applet.

[Reglink parameters]

<param name="regcode" value="NO">      ; Registration code (if you have it)
<param name="reglink" value="NO">      ; Optional URL link when the applet
                                         is "clicked"

To activate the reg parameters, read the shareware registration notes.
In the "regcode" parameter, place the registration code you purchased 
from us. If the code is correct and the applet is run from the registered
domain name, "link" parameters will be enabled and the applet will be
linked to an associated URL when it mouse-clicked.

<param name="regnewframe" value="YES">    ; Reglink opened in new frame?
<param name="regframename" value="_blank">; Name of new frame for reglink

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".

<param name="statusmsg" value="Snow">     ; Statusbar message

Here, you set a message which will be displayed when you mouse-over
the applet.

[Snow layers]

<param name="flakes1" value="500">        ; Number of far flakes
<param name="flakes2" value="300">        ; Number of middle flakes
<param name="flakes3" value="100">        ; Number of near flakes
<param name="flakes4" value="0">          ; Number of foreground big flakes

The snow flakes are animated on 4 separate layers: far, middle, near
and foreground layers. Then, you can specify the number of flakes on
each layer placing a number at flakes1, flakes2, flakes3 and flakes4 
parameters, respectively.

To make a more realistic snow, we suggest to produce more far flakes than
near flakes.

NOTE:

You can set some layers without snow by placing "0" at respective parameter.
However, it's not recommended.

[Snow fall speed]

<param name="speed" value="7">              ; Snow fall speed (1..50)

With "speed" parameter, you can determine the snow falling speed; a good
value is 7, but you can specify any value between 1 to 50.

[Wind setting]

<param name="windmax" value="1">        ; Max speed attained by wind (0..3)
<param name="windvariation" value="7">  ; Wind variation frequency (0..10)

Optionally, you can add wind, to control the snow fall direction. Two parameters
are responsible for wind setting:

The "windmax" determine the maximum speed of the wind. Placing the value 0
in this parameter will disable the wind.

The "windvariation" parameter determines how fast the wind direction changes.
It can be set at 0 to make the wind blocked, or set a value up to 10 to make 
the wind variable.

[Background]

<param name="backimage" value="ansnow.jpg"> ; Background image
<param name="bgcolor" value="000133">     ; Background colour in hex rrggb format

If you want to display a background image, replace "NO" by the image path.

The background colour, if background image is absent, is determined by the
"bgcolor" parameter, entering the value in hex RRGGBB, like html format,
but without the prefix #.

[Text over the snow]

<param name="overtext" value="NO">        ; Snow over text? ("YES", "NO")

The "overtext" determines if snow can overwrite scrolltext.

[Overlay image]

<param name="overimg" value="NO">           ; Optional image over applet
<param name="overimgX" value="0">           ; Over image X offset
<param name="overimgY" value="0">           ; Over image Y offset


With the "overimg" parameter you can specify the name of an image that will
be shown 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 position the image over the applet area.
