Changing the Mask Type

To change the type of a mask:
  1. Click the mask to select it.
  2. On the toolbar, click Mask type button, the Mask type button, and select a type of mask from the list:
    • Mask: Covers the content that is inside the selected area.
    • Reverse mask: Covers the content that is outside the selected area.

      This option is useful, for example, when you want to remove border shadows from scanned documents.
