AnfyFire - Copyright (C) by Fabio Ciucci 1996-99


This applet can generate and animate a realtime "fire" effect. This applet
 is fully parametrized, so you can generate various kinds of fire effects.

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

NECESSARY FILES.

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

fire.class
Lware.class
anfy.class

Plus, fire.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):

INSTRUCTIONS.

The following instructions describe how to change the 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 parameters "fwidth" and "fheight" determine the "internal" width and
heigth of the fire, but will be identical to the "real" size only if resx=1 
and resy=1.

In fact, resx and resy are sort of "scalers", "zoomers", or "stretchers",
so to speak: if fwidth and fheigth are set to 8 and 10, and resx=2 & resy=2,
you will have a "real" size of 16 x 20. The real size is fwidth*resx X
pheight*resy.

This effect looks nicer when resy is greater than resx.

Regarding the fire cutting values, fcut and fsub: fcut must be higher
than fsub, and some values will generate wrong effects. Optimum range
 is 1-127.

The deflight (0-127) determines the minimal light at the base of fire. 
With the value of 0, the fire will have more black holes than the fire of 
the value 127.

If you like the fire as a rectangular block, set fmode=1. If you like the
fire as a convex (conical) flame, set it to 2.

You can determine the smoothing of random generator with rndrep (1-9). 
With lower values you will have less smoothed flames, and vice versa.

In the palette, there are 3 valuables for Red Green Blue (RGB). Each of 
them can take a value from 0 (none) to 8 (full), and they are named 
paletteR, paletteG, paletteB.

You can generate red (fire), green (magic), blue (gas) flames... there
are 700 combinations possible.
