            BookFlip - Copyright (C) by Fabio Ciucci 1998/99


This applet can execute a "book flip" transition between any identically
sized GIF or JPG images.

It is based on original code by Dolf Van Der Schaar, which is used under
license.

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

Apart from bookflip images, and an optional overlay image, the following
3 ".class" files must be uploaded: 

bookflip.class

PARAMETER DESCRIPTIONS.

The following instructions describe 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 credit 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.

Applet size is determined by "res": "res=1" shows the graphic at original 
size, "res=2" shows it at double size, etc.

The "width" tag must be equal to images width.
The "height" tag must be equal to images height + extrah parameter.
The extrah gives an extra space above and below the image area.

For example, if images are 100 pixels in height, and you place a value of
50 for extrah, the applet "height" must be 150.

It is important to update the width and height tags, otherwise the applet
will not display properly on browsers.

The number of images for the crossfading slideshow is unlimited, but
the minimum is 2.

If you want to fade among just 2 images, type:

<param name=image1 value="imfad1.gif">
<param name=image2 value="imfad2.gif">

If you want to fade among 3 images, type:

<param name=image1 value="imfad1.gif">
<param name=image2 value="imfad2.gif">
<param name=image3 value="imfad3.gif">

Repeat the code for each image. 

On each image, you can choose the kind of transition, using flip1, flip2,
flip3, ... etc parameters.

There are 8 transtition effects, each of which corresponds to a value 
between 0 and 7:
       
0: IN -> up-right
1: IN -> down-right
2: IN -> down-left
3: IN -> up-left
4: OUT -> down-left
5: OUT -> up-left
6: OUT -> up-right
7: OUT -> down-right

With "flipcurve" parameter, you can control how big the flipping curve is.

Placing in the "shading" parameter a value higher than 0, you will enable
an extra shading effect. This will slow down the applet in most cases.

You can set a message for each image in the "statusmsg" code. "Statusmsg1"
 is the message displayed with the first image, "statusmsg2" the second 
image, etc.

When you purchase and register the applet, the "link1","link2", etc.
parameters are enabled and this applet can become a crossfade banner as
follows:

<param name=link1 value="http://(name of link">
<param name=link2 value="http://(name of link">
You can place a URL link related to each image.

The speed parameter determines the speed of fade between images. You need
to specify the number of frames. A good value is 8, but not determined.

The "pause" parameter, in milliseconds, determines the "hold" time for
 images between the fades.

If "extrah" is greater than 0, remember to set the background colour at the
same as the html page colour.

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