INTRODUCTIONS.

This applet reloads an image from a given URL location every a specified
number of seconds. In other words, it can display the frames generated
by a webcam. Well, what is a webcam? For those who are not familiar
with this technology, I will give you a brief description.

Webcam is a set of software and a camera, which broadcast any sequences
to the web in realtime. Some of the most popular webcam software may be
found here:

http://www.camcentral.com/links/software.shtml
http://www.kolban.com/webcam32/
http://www.users.fast.net/~lmo/easysnap/

These software with cameras automatically take pictures in jpeg format
and ftp them to your desired site.
Since, the software snaps pictures continuously, your cameras can be
virtually "live". 

Usually, the timing of reloading the image file, which your webcam software
ftp to your site, is determined by the <meta> tag.

For instance, <META HTTP-EQUIV="refresh CONTENT=10"> orders your browser
to reload the page every 10 seconds. This is simple, but effective.

So, what AnfyCam does?

AnfyCam works as an enhanced <META> tag in above use. It can not only load
images in selected timing, but apply cross-fade effect, handles zooming
and even allows you to set an overlay transparent gif image over the Cam
image.

Note: 

The anfycam applet must be loaded from the same machine where the 
target image is loaded; otherwise it will not work due to Java(tm) security
restrictions.

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

NECESSARY FILES

The following 3 ".class" files must be uploaded to the site: 

anfycam.class 
Lware.class
anfy.class

Plus, for speedy loading on recent browsers, you may want to upload:

anfycam.jar 

NOTE:

You must always upload .class files, even if you choose to use .jar file.
Otherwise, visitors who use old browsers can't see the applet.

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

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):


<applet archive="anfycam.jar" code="anfycam.class" width="260" height="243">

PARAMETER DESCRIPTIONS

The following instructions describe the meaning of the available 
parameters for this applet:

[Specify the applet and its size]

<applet archive="anfycam.jar" code="anfycam.class" width=260 height=243>

Here, you specify the applet name and its width and height in pixels.

[Credit parameter]

<param name="credits" value="Applet by Fabio Ciucci (www.anfyteam.com)">

Attempting to change the credit parameter will disable the applet.

[Registration parameters]

<param name="regcode" value="NO">         ; Registration code 

To activate the reg parameters, read the shareware registration notes.
In the "regcode" parameter, place the registration code you purchased 
from us. If the code is correct and the applet is run from the registered
 domain name, "link" parameters will be enabled and the applet will be
linked to an associated URL when it mouse-clicked.

<param name="reglink" value="NO">          ; URL link(optional) when clicked
<param name="regnewframe" value="YES">     ; Reglink opened in new frame?

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.

<param name="regframename" value="_blank"> ; Name of new frame for reglink

You can also set a custom frame name, such as "myframe1".

[Resolution]

<param name="res" value="1">               ; resolution (1-8)

Resolution parameter decides how bigger the actual image is displayed.  
 
For example, the value 3 gives three times as big image size as the actual image
has. So, it works as a zooming parameter. Do not set too high value, unless you
love terrible picture! 

[WebCam image settings]

<param name="url" value="mycam.jpg">         ; WebCam image location

Here, you set the image url for WebCam. The path can be either absolute or
relative.

NOTE:

You must place the anfycam.class at the directory where WebCam image reside.

<param name="interval" value="25">         ; Delay between frames reload

Next, set the timing between frames in mili seconds.

<param name="fadespeed" value="8">         ; speed of fade (1-255)

This parameter determines the image fade speed. The actual speed is given 
by 256/(the number entered in this field). We recommend a value 8, which 
gives 32 frames per second.

<param name="progressivefade" value="YES"> ; Progresive fading ("YES" or "NO")

You can optionally set progressive fade mode. This will fade the image pixels
not at same time, but with some steps.

<param name="statusmsg" value="Cam applet">  ; Statusbar message

A status message is a message which appear at the bottom of a browser window,
when you mouse-over the applet. Enter any message here.

Note: 

this message is followed by the interval countdown for next frame.

[Overlay image]

<param name="overimg" value="NO">           ; Optional image over applet
<param name="overimgX" value="0">           ; Over image X offset
<param name="overimgY" value="0">           ; Over image Y offset


With the "overimg" parameter you can specify the name of an image that will
be shown 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 position the image over the applet area.
