A Java-compatible image process package?

Hi,

I want to do automatic white balancing, image sharpening, and watermark addition in Java. Is there a good open-source jar package that can do such jobs?

The focus is the first two if there is no such package that can do the three tasks at the same time.

Thank you!

Sharpening isn't that complicated, e.g. here:
http://www.jhlabs.com/ip/filters/

White balance is a bit harder.  You might be able to use the plugin here for ImageJ:
http://imagejdocu.tudor.lu/doku.php?id=plugin:color:chart_white_balance:start#introduction
which is a Java image processing tool:
http://imagejdocu.tudor.lu/

You may be able to use the plugin code directly (if you take a look at it closely) or repackage the code yourself.  The plugin looked to be listed as public domain software.

I'm not aware of any tools for watermarking but there are examples on the web for how to do this yourself, e.g.
http://freecode-freecode.blogspot.com/2008/06/how-to-add-watermark-to-images-in-java.html

I know it's more than the 1 jar you had hoped for but shouldn't be hard to pull it all together in an hour or two.

Hope that helps,

Doug
