Using anti-aliasing with selections
Anti-aliasing produces a smooth-edged selection by partially filling in pixels along the edge, making them semitransparent. You can apply anti-aliasing to selections as you create them. For more information about creating selections, see Creating selections.
After a selection is created, you can apply anti-aliasing based on the selection’s shape. You can also restore the original anti-aliasing of an object that was pasted into an image. Restoring anti-aliasing is useful if you made the selection without anti-aliasing and you want to smooth the edges of the selection.
