You can convert a vector shape to a bitmap selection, and then use the bitmap tools to edit the new bitmap.

To convert a path to a marquee selection:

  1. Select a path.
  2. Select Modify > Convert Path to Marquee.
  3. In the Convert Path to Marquee dialog box, select an Edge setting for the marquee selection that you are about to create.
  4. If you chose Feather in the Edge setting, specify the value you want to use for the amount of feather.
  5. To convert the selected path to a marquee, click OK.

    NOTE

    Converting a path to a marquee deletes the selected path. If you would rather not delete paths when you convert them to marquee selections, you can change the default setting. Select Edit > Preferences > Editing, and then clear the setting for Delete paths when converting to marquee.
