AnfyBlobs 2.1 - Copyright (C) by Fabio Ciucci 1996/98 This applet can generate and animate a realtime "blobs" effect, a sort of "light interference" between lightballs. Remember that are needed both blob.class , blobs.class , Lware.class and anfy.class. You must upload these 4 .class files and insert the tag on your html document to add this applet to your page. This applet is fully parametrized, so you can generate all kinds of blobs you want. Here an example of what you have to write in the html (the things anfter the ; are comments with min-max values acceptet): ; Name, Width, Height ; Register code (if you have it) ; URL where go optionally when clicked ; Reglink opened in new frame? ; Name of new frame for reglink ; Statusbar message ; resolution (1-8) ; number of blobs (2-8) ; minimum speed (1-15) ; Fix netscape bug ; Blob val 1 ; Blob val 2 ; Blob val 3 ; Color palette (1-6) ; Sinus movements ("YES" or "NO") ; Star shape ("YES" or "NO") ; Negative colors ("YES" or "NO") ; File for scrolltext or "NO" ; Txtscroll y offset ; Txtscroll speed ; Txtscroll font name ; Txtscroll bold ("YES" or "NO") ; Txtscroll font size ; Txtscroll shadow ("YES" or "NO") ; Txtscroll color (red component) ; Txtscroll color (green component) ; Txtscroll color (blue component) ; Txtscroll shadow col. (red c.) ; Txtscroll shadow col. (green c.) ; Txtscroll shadow col. (blue c.) ; Txtscroll jump aplitude ; Txtscroll jump speed ; Txtscroll sineshape amplitude ; Txtscroll sineshape movement ; Txtscroll sineangle / pixel ; Memory deallocation delay ; Task priority (1..10) ; Fix Netscape 3.0 bug ("YES","NO") ; Min. milliseconds/frame for sync Sorry, your browser doesn't suppor Java. ; Message for no java browsers. ; End of applet tag NOTE: Don't place "; comments" on final HTML!!! Copy and paste in your html document this cleared and correct tag: Sorry, your browser doesn't suppor Java. --------- Here detailed instructions about how to change parameters: The size of the applet is determined by "width" and "height" tags. The applet can be of any size. 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 is faster. I think the best choices are 1-3. 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 number of blobs can go from 2 to 8. The minimum speed can go from 1 to 15... better to use low minspeed on small bwidth and bheight, and high minspeed when the size is greater than 60. With bval1,bval2,bval3 parameters is possible to change the intensity of blobs. With "numpal" you can choose between 6 different color palettes. Setting "sinemode" parameter to "YES" the blobs will move like waving, otherwise setting it to "NO" blobs will bounce. Setting "starshape" parameter to "YES" the blobs will have romboid shape rather than spherical shape. Setting "negative" to "YES" the effect will display negative colors. --------- Optional Scrolltext parameters: You can optionally activate a scrolltext that will scroll over the applet. If you don't need the scrolltext, deactivate it placing "NO" at the "textscroll" parameter. Otherwise you must supply the name of an ASCII text file, where you must write the text that you want to be scrolled. Is supported one only line of text, that can be long as you want. Remember to upload the text file too, if you activate the scrolltext! If activated, here are the parameters: With "textoffset" you choose the Y offset from the top: placing it to 0 the scroll will be placed on the top, for example, and placing a value near the height of the applet it will scroll at the bottom. With "textspeed" parameter you decide the scrolling speed. With "textfont" you choose the font of text. Don't choose a strange or not standard font, not present in all systems. The most common fonts are "Arial", "TimesRoman" and "Courier". If the required font is not present, the most "near" will be used. Setting "textbold" to "YES" you will enlarge a bit the font, otherwise set it to "NO" for normal contours. With "textsize" you can change the size of text font. The most common sizes are: 8,9,10,11,12,14,16,18,20,22,24,26,28,36,48,72. Intermediate values will be scaled to nearest available size. Setting "textshadow" to "YES", a shadow will be added to textscroll. Otherwise, setting it to "NO", any shadow will be "projected". You can choose the color of text with: TextColR = Red component of color (0-255) TextColG = Green component of color (0-255) TextColB = Blue component of color (0-255) For example, 0,0,0 is black, 255,255,255 is white, 255,0,0 is red, 255,255,0 is yellow, 128,128,128 is grey. You can compose any color you want, do it trying manually or use any paint program's color selector to find Red Green Blue components of your desired colors. With TextSColR,TextSColG,TextSColB you can select the color for text shadow. If you like, you can activate the text jumping function. If "TextJumpAmp" is set to "0", any jumping will be shown. But increasing the value will result in text jumping: more aplitute, more high jumps. With "TextJumpSpd" parameter you can select the jumping speed. If you like, you can also activate the sine scroll function. If "TextSineAmp" is set to 0, no sine distortion will be generated. But increasing the value will result in the that the text is waving. The higher amplitude, the more waving. With the "TextSineSpd" parameter you can select the speed of the wave. With the "TextSineAngle" parameter you control how many degrees in a sinewave shape the text will be deformed for each pixel. A higher value gives more distortion. --------- 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 rus 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 "fixnetscape" parameter is useful only when the applet is visualized with Netscape 3, under Win95. In fact, Netscape has a bug displaying IndexColorModel, resulting in less colours than normal and dithering. Setting "fixnetscape" to "YES", the effect will run slower on all browsers, but will have correct colors on Netscape 3.0. Setting it to "NO", the effect will run faster on all browsers, except Netscape 3.0 that will display in worst way. Notice that Netscape 4 and Explorer haven't this problem. 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. --------- Copyright and distribution notices 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. --------- Fabio Ciucci fabioc@anfiteatro.it http://www.anfiteatro.it/java.html
