Anfy Lake 1.0 - Copyright (C) by Fabio Ciucci 1998


This applet can generate a reflection effect under any GIF or JPG image.
It is very similiar to Lake and DorianGray applets made by other authors,
but this one has a different approach since it it calculated in realtime,
so it require less memory (about 10 times less!).
I made a similiar effect on 1990 on Amiga computers using assembler language,
so I think I haven't copied this idea to others that made it in java lately,
in 1996-97.
Remember that these three are needed: AnLake.class , Lware.class and anfy.class.
You must upload these 3 .class files and insert the <applet> tag on your
html document to add this applet to your page.
This applet is fully parametrized, so you can generate all kinds of 
lake applets that you might want. Here's an example of what you have to 
write in the html (the things after the ; are comments with min-max values.

                             ---------

Here detailed instructions about how to change parameters:

The credits parameter can't be changed otherwise the applet will not work.
For the reg parameters read the shareware registration notes at end of text.

The GIF/JPG image can be of any size.
The aplet size must me same of image in width, double in height: for example,
if the image is 160x100, applet size must be 160x200.

If res=1, remember to place the exact size of image in "width" and "height"
tags, with height multiplied by 2.
If res=2, place double values of width and quadruple of height, if res=3
triple values of width, sit times the height, etc.
In fact, res is a sort of zoomer.

With "wavspeed" parameter (values from 1 to 200) you decide the speed of
waving.

With "perspective" parameter (values from 1 to 100) you decide how the waves
have to be stretched for perspective simulation.

The "farwaving" parameter (values from 1 to 10000) you decide how string the
far waves (top of lake) must be.

With "wind" parameter (values from 1 to 20) you decide how string the waving
will be.

Optionally, you can make the wind dynamically change, setting the
parameter "windvarval" as more than 0 (higher values mean higher change).
Then, with the parameters "windvarmin" and "windvarmax" you can control the
min and max values of wind reached.


                             ---------


Optional Scrolltext parameters:


You can optionally activate a scrolltext that will scroll over the applet.
If you don't need the scrolltext, deactivate it placing "NO" at the
"textscroll" parameter.
Otherwise you must supply the name of an ASCII text file, where you must
write the text that you want to be scrolled.
Is supported one only line of text, that can be long as you want.
Remember to upload the text file too, if you activate the scrolltext!

If activated, here are the parameters:

With "textoffset" you choose the Y offset from the top: placing it to 0 the
scroll will be placed on the top, for example, and placing a value near the
height of the applet it will scroll at the bottom.

With "textspeed" parameter you decide the scrolling speed.

With "textfont" you choose the font of text. Don't choose a strange or not
standard font, not present in all systems.
The most common fonts are "Arial", "TimesRoman" and "Courier".
If the required font is not present, the most "near" will be used.

Setting "textbold" to "YES" you will enlarge a bit the font, otherwise set
it to "NO" for normal contours.

With "textsize" you can change the size of text font.
The most common sizes are: 8,9,10,11,12,14,16,18,20,22,24,26,28,36,48,72.
Intermediate values will be scaled to nearest available size.

Setting "textshadow" to "YES", a shadow will be added to textscroll.
Otherwise, setting it to "NO", any shadow will be "projected".

You can choose the color of text with:

TextColR = Red component of color (0-255)
TextColG = Green component of color (0-255)
TextColB = Blue component of color (0-255)

For example, 0,0,0 is black, 255,255,255 is white, 255,0,0 is red,
255,255,0 is yellow, 128,128,128 is grey.
You can compose any color you want, do it trying manually or use any paint
program's color selector to find Red Green Blue components of your desired
colors.

With TextSColR,TextSColG,TextSColB you can select the color for text shadow.

If you like, you can activate the text jumping function.
If "TextJumpAmp" is set to "0", any jumping will be shown.
But increasing the value will result in text jumping: more aplitute, more
high jumps.

With "TextJumpSpd" parameter you can select the jumping speed.

If you like, you can also activate the sine scroll function.
If "TextSineAmp" is set to 0, no sine distortion will be generated.
But increasing the value will result in the that the text is waving. The
higher amplitude, the more waving.

With the "TextSineSpd" parameter you can select the speed of the wave.

With the "TextSineAngle" parameter you control how many degrees in a sinewave
shape the text will be deformed for each pixel. A higher value gives more
distortion.

                             ---------


Compatibility parameters:


The "memdelay" parameter is useful only to run the applets without problems
on some bugged versions of Netscape 3, that don't deallocate correctly
the memory allocated, resulting in filling all the memory after a minute
the applet is running. This can cause also a system crash in some cases.
Last versions of browsers have fixed this problem, but if you want to run
the applets on old bugged browsers too, set "memdelay" to low values, like
"10" or "16", for example.
But this will slow down a lot the applet speed, so you have to choose
between speed (memdelay set to 1000 or higher) or slow compatibility with
old browsers (memdelay set to 20 or lower).

The "priority" parameter is useful mainly when you are running more than
one applet in same page, and one slows down or hangs.
If this applet rus too slow or hangs because other one steal all the CPU
power, try increasing the priority.
Otherwise, if this applet runs well and others slows down, decrease the
priority. Consider the min priority is 1, normal priority is 5, and the
max priority is 10. Usually a priority of 3 is ok for single applets.

The "MinSYNC" parameter must be set to a value between 8 and 16 to slow
down animation in the case it runs too faster on faster computers or because
the applet size is very small. The optimal value seems to be 10, but you can
disable this feature placing a value of 0 if you see flickerings or excessive
slow down.
If the applets steal 100% of CPU power or slows down the browser and Operating
System, try increasing MinSYNC until all runs ok.
Usually values between 40 and 400 fixes all problems, even if applet slows
down for compatibility.
