Has anyone every used imgscalr

I am new to netbeans and java. Yes I have searched around for an answer to my problem. I've found similar postings but none of them helped me. I am developing a java desktop application using netbeans IDE 6.9.1 and simply want to scale an image. I found a library called imgscalr here imgscalr – Java Image Scaling Library | The Buzz Media and added it to my project libraries. But when I try to use it in my program, I get the "cannot find symbol" error. The package is called "com.thebuzzmedia.imgscalr" but I cannot import it either.
Can someone help me with this?

Never mind!
