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. ************************************************************************ NECESSARY FILES. Apart from bookflip images, and an optional overlay image, the following 3 ".class" files must be uploaded: bookflip.class Lware.class anfy.class Plus, bookflip.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 explanations and acceptable min/max values. They are not part of the applet language): ; Registration code (if you have it) ; Reglink opened in new frame? ; Name of new frame for reglink ; resolution (1-8) ; Image 1 to load ; Image 2 to load ; Image 3 to load ; Link 1 ; Link 2 ; Link 3 ; statusbar msg on image 1 ; statusbar msg on image 2 ; statusbar msg on image 3 ; Flip effect img 1 (0 .. 7) ; Flip effect img 2 (0 .. 7) ; Flip effect img 3 (0 .. 7) ; speed of fade (1-255) ; pause (value = milliseconds). ; Extra height (applet w. - img w) ; Flip curve (1 .. 10) ; Shading (0 .. 4) ; Red in background (0 .. 255) ; Green in background (0 .. 255) ; Blue in background (0 .. 255) ; 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 ********************************************************************* 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: If you want to fade among 3 images, type: 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: 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.
