change brightness of image
How do you load an image and then add a slider to change the brightness of that image? what does the code look like for this?
-
Do you need to know how to change the brightness, or do you alreadys know that and just want to know how to make the slider do it?

You need the JAI package to be able to manipulate images. (There is Java2D in j2sdk but JAi is just so powerful.) And if you download the JAI Tutorial on sun's website, they have examples in there with the source code. I'm sure that there is one there that does what you need.
Cheers,
Rachel
