This feature is an excellent tool to use when working with text objects, vector illustrations, or high contrast images. To open the Rotate dialog box, choose Effects > Rotate Right or Rotate Left > Other. Make sure you select Hard rotate for image to enable Anti-alias image. You can also activate this dialog box by using the keyboard command Command+ R (Mac) or Ctrl+R (Windows). Original bitmap image before rotation.
