AnfyRotate - Copyright (C) by Fabio Ciucci 1996-2002


This applet can zoom and rotate (eventually distorted) any GIF or JPG image.
The only requirement is that this image must be equally sized to one of the
powers of 2 (64x64 pixel, or 32x64, 128x128, ...). This applet is fully
parametrized, so you can generate all kinds of rotator effects.

NECESSARY FILES.

Apart from a background image and/or a foreground image, the following 3
".class" files must be uploaded: 

Rot2.class
Lware.class
anfy.class

Plus, Rot2.jar for speedy loading on recent browsers.

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 GIF or JPEG image must be equally sized to one of the powers of 2 (64x64
pixel, or 32x64, 128x128, ...). For example, valid sizes are 8*8, 8*16, 8*32,
16*32, 32*16, 32*32, 64*64,64*32, 128*32, 128*64, 32*128, 128*128, 256*128...

The size of the applet is determined by the width and height tags, and can be
different from the size of the image.

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 faster.
Optimum choices are 1-3.

If you want to fill the applet area with tiling the image, set the "tile"
parameter to "YES". If you set it to "NO", a background colour will be
used to fill the space outside the single image.

With "backr", "backg" and "backb" parameters, you can control the RED, GREEN
and BLUE components of the background colour.

You can load a background image by placing it's name in the "backimage"
parameter. This image must be the same size as that of the applet if res=1, 
half the size of the applet if res=2, and so on.

Rotmode is the mode of running. Here are the modes:

1) Zoom and Rotate
2) Rotate only
3) Zoom only
4) Distort only
5) Zoom and Distort
6) Automatic show: ZoomOnly, then Zoom&Rotate, then Zoom&Distort

You can control the speed of rotation with "rspeed"; the min value
and max value for zoom (when you change zoom direction) with "zoommin" and 
"zoommax", and  the speed of zoom with "zoomspd".

You can also determine the distort factors: "modix" for X axis and "modiy" for
the Y axis.

With "distval", you can control the overall distortion strength, placing a
value from 1 to 255.

Finally, you can decide the timing of mode 6 (automatic show): auto1 is the
time to wait before swap between zoom and zoom&rotate, and auto2 is used
to wait for the other swap, from zoom&rotate to zoom&distort.
Swap2 must be >= swap1. If swap1=0 then you skip Zoom and start
directly with Zoom&rotate. If swap1=swap2 you skip Zoom&Rotate, jumping
from zoom only to distort & rotate, and so on....
