Anfy BumpMap - Copyright (C) by Fabio Ciucci 1997-2002


This applet shows a lightsource over a "bumpy" surface which casts shadow
over a selected screen image, which can be the same image as the bumpy map.

This applet is based on original code by Martin Zettergren that is used 
under the licence.

The transparent image sun.gif is a courtesy of Lone Star Posse Prod. Inc.

The applet can use any picture in any size and it can optionally have a
separate bump-image, which must be the same size as the screen picture. 

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

NECESSARY FILES.

Together with a screen image and an optional bump map image, you need to
upload the following files: 

anfybump.class
Lware.class
anfy.class

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

PARAMETER DESCRIPTIONS.

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 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.

Changing the width and height of the applet will make the visible area of
the bumpmap larger. You can set a width and height that are smaller than
the picture to display, however we recommend that you set the applet width
and height at the same size as the bump map image. 

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

The "picture" param is the filename of the picture to display. Make sure that
this picture is available, or the applet will not work. Remember that using
the correct upper and lower case is very important, or the applet will not
run on non-P.C. machines. Example: Symb256.jpg should be written exactly as
it appears, NOT SYMB256.JPG nor sYmB256.jPG.

The "bump" parameter decides if you want to use a separate bump-image
 or if you want to calculate it from the screen picture. The latter is 
recommended since it takes up less bandwidth, and the calculated bump-image
 is run through some advanced filters to make it look realistic. Simply set
 this parameter to "NO", if you want to use a calculated image, or to the 
filename of the bump-image if you want to use that option.

Example: SymbBump.jpg or whatever your bump-image is called.

The "bump_height" parameter controls the height of the bump. If set high, 
the shadow will be cast so that it appears to be higher bumps in the picture.

The "angle_x" parameter controls the movement of the lightsource in the
horizontal direction. A higher value will make the lightsource go faster per
frame horizontally.

The "angle_y" parameter controls the movement of the lightsource in the
vertical direction. A higher value will make the lightsource go faster per
frame vertically.

The "lightsize" param controls the size of the lightsource, ranging from 3 to
whatever you would like. The size is calculated as 2^n, where n stands for the
lightsize.

A "lightsize" of 9 would give a lightsize that is 512x512 pixels in size.
The minimum lightsize is 8x8. There is no maximum limit, but due to memory
aspects, the lightsize shouldn't exceed 512x512 pixels (9).

With "lightpower" you can choose a light intensity from 1 to 100.
With lightmin and lightmax parameters, you can choose darker and lighter
tolerances between 1 and 511.

The best test of this effect is with mouse movements, with the
feature of interactive placement of the light enabled. Usually the light is
moved around the image automatically, but if you set the "interactive" 
parameter to YES, you can move the light with the mouse when it is over the
 applet area. The automatic movements will restart after 2 seconds of no 
user intervention. If you set to "NO", the user interaction option will be
disabled.
