Changing size of the image

Question

I am trying to change the size of an image using setPreferredSize(int width, int height)
The API says that if the size specified is less than the minimum width and height, the minimum width and height is used. But they have told that if the width and height specified is more than the minimum it would be accepted.
I wrote this program. I am using the heart image in this forum as the picture. But the size isn't getting changed. I am trying to scale the image.
Here is the code. I am using ImageItem.setPreferredSize( )
