The fliplay applet
Setup:
The two class files "fliplay.class" and "flickframe.class" are needed. Then the applet has to be initialized in a html-page. The fliplay applet allows the usage of several parameters. A typical example is given here:

<APPLET code=fliplay.class width=320 height=200>
<PARAM name=File value=fishix.fli>
<PARAM name=Speed value=30>
<PARAM name=Loops value=10>
<PARAM name=End value=-1>
</APPLET>

The width and the height values have to correspond with the size of the fli/flc-animation. The parameter "File" points to the fli/flc-animation. The best way is to keep all files together in one directory. The two class files, the fli/flc-file and the html file. Only the "File" parameter is obligatory. The following table explains the function of the other parameters:

Parameter Default value Alternative values Function
Speed 100 Positive integer Delay time between frames in milliseconds
Loops -1 Positive integer Number of loops to be played (-1 = infinite)
End 0 Integer Number of frame, which is displayed when the animation stops after N loops. Negative number means counted backwards from the end of the fli/flc-animation.
Auto no yes If "yes", the auto-reverse (Ping-Pong) play is enabled.
Reverse no yes If "yes", the animation is played backwards.
ClickPanel yes no If "yes", a control panel occurs when the animation is stopped by mouse click.
Keyboard yes no If "yes", then the animation can be controlled interactively by the keyboard.
Block 64 Positive integer Defines the block height for the internally used patch blocks. 
A smaller value may save memory but can slow down the animation.
Box no yes If "yes", then internally used boxes are marked and displayed. This is mainly for control purposes and disturbs the original images.
Debug no yes If "yes", a lot of internal information is written to the Java console.
TextColor white black, red Color of the text. During loading the 
first frame is displayed and the number of the currently loaded frame is written in the lower left corner using the specified color.
PanelColor 0 1,2,3 Set the color style for the panel, which appears when the animation is stopped by mouse click.
(v1.1b)
MinDelay 30 Positive integer Minimum delay time in milliseconds
MaxDelay 10000 Positive integer Maximum delay time in milliseconds
ZipFile no yes If "yes", the input file is a ZIP file, which contains as first entry the FLI/FLC file

Memory usage:
The applet stores internally images which contain parts of the animation frames. The border of these images can be made visible by setting the "Box" parameter to "yes". Routines of the Java library are used to manage the images. Therefore the images may occupy a large amount of memory depending on the animation, the browser, the window system and perhaps some version numbers. When the animation is loaded something like:
"Update Pixels: 419070 (13.0959375 %)"
is written to the Java console. The first integer number indicates the sum of the pixels of all internally stored images. On true color systems - using a standard browser - the memory requirement can be four bytes per stored pixel. Thus, in the given example 1.6 Mbytes are occupied on some machines to store the images. The size and the number of the internally used images depends on the "Block" parameter. A lower value typically increases the number of images but decreases the overall pixel count. Because all the images have to be processed the animation speed may be reduced, when the "Block" parameter is reduced. If memory consumption is a problem various values of "Block" should be tested (below 16 is usually not reasonable).
Colors:
No problems with colors occur on true color systems. When the fliplay applet is started on systems in 256 color mode some colors might be distorted. This depends on the colors used in the FLI animation and on the colors required for the window system or other applications. If there are not enough free colors, sometimes the browser/system assigns a spare color which is close to the disired one. Other browsers/systems dither the images. However, FLI animations with many colors might have probelms on some systems.
Zip File:
To reduce the transferred data the FLI files can be compressed. Therefore the FLI file is compressed in a ZIP archive. Best is to have only one entry in the ZIP archive. The parameter "ZipFile" indicates, if a normal FLI/FLC file is loaded or a compressed one. This option may not work with older browsers, because classes from a newer Java version are used.
