How do I apply anti-aliasing to the edges of a layer?

Question

How do I apply anti-aliasing to the edges of a layer?I have a layer that has rough edges. I want to apply anti-aliasing to it so it blends well against the background. What is the best way to do that in CS5?

Answer 1

you can apply a layer mask to the image and feather the edges to get it smoother looking. it will also loose some of the edge and look softer. you can also increase the dpi of the project for a technical AA effect, if it scales well enough
