What the Action can do: This Action lets you do the following:
- It lets you apply a sharpening effect to an image imported into a graphic item.
- Enabled: This option is checked by default. When checked you will see a live preview of the effects applied when options are used in the Actions palette. To see a "before and after" of the original image (with and without the Action applied), switch the Enabled option on and off. Remember to leave it checked when you have finished.
- Apply to Alpha Channel: The default is for this option to be switched off, which means that the motion blur effect when used on an imported graphic with an "alpha channel" (such as a PNG-24 cut-out image with a transparent background) will finish where the alpha channel begins. Check this option if you wish to use the motion blur effect beyond the edge of a cut-out image.
- Diameter: The default setting is "3" (which means that is sharpens the image unless the Enabled option is unchecked) and can be increased to 17. This slider (and value field) lets you increase the value to increase the amount of sharpening effect applied to the image.
