I've an applet that have to do some stuff
about digital sign, after, it should write
the decoded string in the client file-system.
But I guess I couldn't write on the client f.s.
from an applet.
Before this error I had that my needed class
imported in order to achieve the main stuff
had not been instantiated, having anyway mentioned
all the jar I needed.

now I do all that I wanted.
I've added the options for chosing colors from a JColorChooser,more you have to pay attention to the starting image color(currentColor var) that you must define in the code.
I give you the entire modified code.

If you want to write the image using the gif format you can use GIF89Encoder that you can find on the acme site
I've found it very simple to use. I give you a snippet of code

Hope it helps!

Have you some snippet of code for write down to
a png file format from an Image?
In few words using your code...

I've to change colour of five images.
I've already setted up the chain that
get the user able to choose the colour
and generate the output with the desired
colours of other html elements.
Now I need to change the colour of gif images.
In other words I need to load in memory a gif image change the colour and write down to the file system.
I've come through sun site and I've found
something about MediaTracker but I'm not sure it's what I'm looking for...
I've seen something about JAI...
Some example?Some suggestion?
