Image manipulation problems.

[blackraven1425]

I;m trying to scale an image (using the imgae's getScaledInstan ce method) before passing it to an ImageIcon, but it looks like the images are cropped. Has anyone had this problem before? Might it scale one side to the right side then crop the remainder on the other?

I've never had that problem. I find quality-wise, getScaledInstan ce is better for shrinking images and AffineTransform s better for magnifying images:
