Applet parameters
|
width, height |
These are the standard applet tags describing the width and height
of the applet in pixels. |
|
image |
The filename of the image to use. This is relative to the html-document. |
|
bg |
The color used for background when loading the image, in format
rrggbb. |
|
dim |
This describes how fast the water pans out. A value of two pans
out immediately while at eight it takes a long time for the water
to settle. Defaults to five. |
| dotsize |
This
is the size in pixels of the 'drops' to be deployed in the water
by the mouse. |
|
ndotsize |
This is the size in pixels of the 'drops' to be deployed in the
water by the 'Noise' feature. |
|
mouse |
One or zero. Enables/disables the mouse-over effect. Defaults to
one. |
|
noise |
One or zero. Enables/disables the static noise effect. This causes
static noise in the water without user interaction. Defaults to
one. |
|
url |
The target url when using the applet as a button or NavBar. If using
a NavBar then this value is any number of target url's, separated
by a space character. Omit this if the applet is not supposed to
link to anything. * Tip - You can issue a mailto: command as you
would in HTML, i.e. mailto:boef@usa.net! * |
|
target |
This option lets the user specify which frame to open a target url
in. If omitted, it targets the default frame. |
|
orientation |
This is the orientation of the NavBar. v for vertical or h for horizontal.
Case-sensitive. |
FAQ.
Here are some common problems and their solution.
Applet works locally
on my computer, but not when uploaded.
If you see a message saying 'Can't find image http://www.test.com/sunset.jpg'
then the image has not been uploaded to the correct folder, or the 'image'
of the applet tag is incorrect. Most webservers treat filenames as case
sensitive. It's very important that you consider this when filling in
the 'image' parameter. For example, if your image is named 'SunSet.jpg'
and your 'image' parameter reads
'sunset.jpg' then you will probably get this problem when you upload your
web.
When I run the applet,
all I get is a black screen and no error message.
If the width and height of the applet does not reflect the width and
height of the image used, this is what happens. Make sure that width and
height are correct.
I use several applets
on the same page, nothing runs smoothly!
You really shouldn't use more than one of these applets on the same page.
These are cpu-intense applets, and the implementations of Java that are
available do not seem to cope very well with having several intense applets
run at the same time. Running two applets on the same page uses more than
double cpu-time.
This should be avoided at all costs!
When I've uploaded
the applets I get a "java.lang.ClassFormat" or a "java.lang.MethodVerification"
It's important when you upload the applet files that you do so in Binary
mode. Uploading them in ASCII mode will ruin the files. The same goes
for images.
What is this rrggbb
format?
The rrggbb format consists of three components: Red, Green
and Blue
in hexadecimal format. The hexadecimal format spans from 0 to f
as opposed to the decimal format 0 to 9. There are two numbers for every
color
component, 00 to FF. This represents 0 to 255 in decimal format.
The best way to get the color you want is to choose it in a good graphics
program, for instance Photoshop or Paint Shop Pro. There you will probably
see the three component values in decimal format. Make a note of them and
