Re: Antwort: watermark

Hi,

I'm talking about this:
http://en.wikipedia.org/wiki/Image:Digital_watermarks.jpg
http://en.wikipedia.org/wiki/Digital_watermarking

We have an article publishing web application, in which publishers can 
upload photos. When photos are uploaded, the system should add a 
copyright watermark to the top of the image.

We are using ImageJ to dynamically create smaller versions of the 
uploaded image, and we also need to dynamically add watermarks.

I searched the API docs for "water" but didn't find anything...

Thanks
