- Anfy Mandel 2.1 - Copyright (C) by Fabio Ciucci 1996/98
-
-
- This applet can generate and animate a realtime Mandelbrot fractal.
- Remember, are needed both mandel.class , Lware.class and anfy.class.
- You must upload these 3 .class files and insert the <applet> tag on your
- html document to add this applet to your page.
- This applet is fully parametrized, so you can generate all kinds of
- Mandelbrot fractals you want.
- Here an example of what you have to write in the html (the things after
- the ; are comments with min-max values accepted):
-
-
- <applet code="mandel.class" width=150 height=150> ; Name, Width, Height
- <param name=credits value="Applet by Fabio Ciucci (www.anfiteatro.it/java.html)">
- <param name=regcode value="NO"> ; Register code (if you have it)
- <param name=reglink value="NO"> ; URL where go optionally when clicked
- <param name=regnewframe value="YES"> ; Reglink opened in new frame?
- <param name=regframename value="_blank"> ; Name of new frame for reglink
- <param name=statusmsg value="Mandel applet"> ; Statusbar message
- <param name=res value="1"> ; resolution (1-8)
- <param name=xstart value="0"> ; X start
- <param name=ystart value="7000"> ; Y start
- <param name=xmin value="60"> ; X min
- <param name=xmax value="-120"> ; X max
- <param name=ymin value="60"> ; Y min
- <param name=ymax value="-120"> ; Y max
- <param name=numpal value="1"> ; Palette number (1-27)
- <param name=memdelay value="1000"> ; Memory deallocation delay
- <param name=priority value="3"> ; Task priority (1..10)
- <param name=MinSYNC value="10"> ; Min. milliseconds/frame for sync
- Your browser doesn't suppor Java. ; Msg in no java browsers
- </applet> ; End of classtag
-
-
- NOTE: Don't place "; comments" on final HTML!!!
-
- Copy and paste in your html document this cleared and correct tag:
-
-
- <applet code="mandel.class" width=150 height=150>
- <param name=credits value="Applet by Fabio Ciucci (www.anfiteatro.it/java.html)">
- <param name=regcode value="NO">
- <param name=reglink value="NO">
- <param name=regnewframe value="YES">
- <param name=regframename value="_blank">
- <param name=statusmsg value="Mandel applet">
- <param name=res value="2">
- <param name=xstart value="0">
- <param name=ystart value="7000">
- <param name=xmin value="60">
- <param name=xmax value="-120">
- <param name=ymin value="60">
- <param name=ymax value="-120">
- <param name=numpal value="1">
- <param name=memdelay value="1000">
- <param name=priority value="1">
- <param name=MinSYNC value="10">
- Sorry, your browser doesn't suppor Java.

-
- Here detailed instructions about how to change parameters:
-
-
- The credits parameter can't be changed otherwise the applet will not work.
-
- To activate the reg parameters read the shareware registration notes.
- In the "regcode" parameter you have to place the registration code you
- purchase from the author. If it is correct and the applet is run from the
- registered domain name, you can use "reglink" parameter, where you can specify
- an URL where bring user when the applet is clicked.
- If you set to "YES" regnewframe, you can specify a frame where load 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.
-
- Otherwise the frame name, for example "myframe1".
-
- The size of the applet is determined by width and height tags.
-
- The res parameter determine the resolution: with res=1 pixels are small,
- but effect is slow, with res=8 pixels are too great but effect fast.
- I think the best choices are 2-4.
-
- About parameters for fractal generation, I don't placed limits to values,
- that can be positive or negative, place values at your own risk.
- here what does the values, that can be positive or negative:
-
- XMin: + scroll right, - scroll left
- XMax: + less width X, - enlarge width X
- YMin: + more height Y, - less height Y
- YMax: + scroll down, - scroll up
-
- Aniway this is not 100% correct. You are free to experiment with the
- mistery of numbers.
-
- Are available 27 different palettes, just select the one you prefer for
- your web page.

- Compatibility parameters:
-
-
- The "memdelay" parameter is useful only to run the applets without problems
- on some bugged versions of Netscape 3, that don't deallocate correctly
- the memory allocated, resulting in filling all the memory after a minute
- the applet is running. This can cause also a system crash in some cases.
- Last versions of browsers have fixed this problem, but if you want to run
- the applets on old bugged browsers too, set "memdelay" to low values, like
- "10" or "16", for example.
- But this will slow down a lot the applet speed, so you have to choose
- between speed (memdelay set to 1000 or higher) or slow compatibility with
- old browsers (memdelay set to 20 or lower).
-
- The "priority" parameter is useful mainly when you are running more than
- one applet in same page, and one slows down or hangs.
- If this applet run too slow or hangs because other one steal all the CPU
- power, try increasing the priority.
- Otherwise, if this applet runs well and others slows down, decrease the
- priority. Consider the min priority is 1, normal priority is 5, and the
- max priority is 10. Usually a priority of 3 is ok for single applets.
-
- The "MinSYNC" parameter must be set to a value between 8 and 16 to slow
- down animation in the case it runs too faster on faster computers or because
- the applet size is very small. The optimal value seems to be 10, but you can
- disable this feature placing a value of 0 if you see flickerings or excessive
- slow down.
- If the applets steal 100% of CPU power or slows down the browser and Operating
- System, try increasing MinSYNC until all runs ok.
- Usually values between 40 and 400 fixes all problems, even if applet slows
- down for compatibility.

-
- Fabio Ciucci is the author and owner of this applet.
- You can use freely this applet to enhance your web pages. But since I am
- the author of the applet, I placed a secret linkware window that will appear
- if the applet is clicked with mouse, only when the applet is online on a site:
- it is external to the web browser, so it will not hit the design of your
- beautyful html page.
- This small window will simply show my name and ask for a link to my java
- applets page.. the user can connect to it or cancel, or hide the window and
- connect after visiting all your pages.
- I hope this credit part is not a problem for you...
- In any case, if link is accepted a new browser window will appear and your
- page will remain on the original window, so you will not lost the visitor.
- Consider you will use an effect programmed by me, without pay, for FREE!
-
- NOTE: You can include the applets archive on CD-ROMS or shareware collections
- and shareware sites without ask me, but only if you leave the archive(s)
- unchanged.
