- AnfyBlobs 2.0 - Copyright (C) by Fabio Ciucci 1996/97
-
-
- This applet can generate and animate a realtime "blobs" effect, a sort
- of "light interference" between lightballs.
- Remember, are needed: blob.class, blobs.class and Lware.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 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):

- ---------
-
-
- 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 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 "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.
-

-
- 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.
