AnfyLens - Copyright (C) by Fabio Ciucci 1996-99 This applet can simulate a lens moving over any GIF or JPG image.This applet is fully parameterized, so you can generate all kinds of lens effects. ************************************************************************* NECESSARY FILES. As well as an image to be animated and an optional overlay image, the following 3 ".class" files must be uploaded: AnLens.class Lware.class anfy.class Plus, AnLens.jar for speedy loading on recent browsers. ************************************************************************ EXAMPLE. Insert the tag in your html document as follows to add this applet to your page (Comments after the ";" symbol are code descriptions and acceptable min/max values. They are not part of the applet language): ; Registration code (if you have it) ; Optional URL link when the applet is "clicked". ; Reglink opened in new frame? ; Name of new frame for reglink ; Statusbar message ; Image to load ; Size of lens ; Diagonal distortion (5 .. 20) ; XY distortion (-40 .. 40) ; Zoom factor (0 .. 30) ; Interaction ("ON" .. "OFF") ; Distortion ("ON" .. "OFF") ; X speed (0 .. 8) ; Y speed (0 .. 8) ; Optional image over applet ; Over image X offset ; Over image Y offset ; Memory deallocation delay ; Task priority (1..10) ; Min. milliseconds/frame for sync Sorry, your browser doesn't support Java. ; Msg in no java 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 displayed as an animated sequence only on latest browsers (Netscape 4 and Explorer 4 or newer). With "overimgX" and "overimgY" you can center the image over the applet area. You can load any GIF or JPG image, but remember to write the exact image size in the width and height tags. You can choose the width of the lens with the parameter "lenswidth". Greater lens size means slower movements. If you select "NO" to "distort" parameter, you will disable distortions, and the zoom will be plain (this is useful especially for applications where the image is zoomed to view it better). The "distdval" parameter determines the diagonal distortion. To have a perfect sphere, use the value 10. Smaller or higher values (the range is 5 .. 20) will change the lens distortion. The "distoxy" value (-40 .. 40) will distort X for negative values and Y for positive values. Choose 0 for normal spherical distortion. As you know, lens effects are useful for zooming images. With "zoomfactor" you will change the lens zooming ability. A value of 0 = no zooming, only distortion. Higher values = higher zooming. The interactive placement feature of the lens is the best way to test this applet, so it should be enabled to give optimum interactive ability using a mouse. Usually the lens is moved around the image automatically, but if you set to "YES" the "interactive" parameter, the user can move the lens with the mouse when it is over the applet area. The automatic movements will restart after 2 seconds of no user activity. If set to "NO", the user will not be able to use the interactive feature. You can control the speed of automatic movement with the "spdx" and "spdy" parameters.
