To filter a TIFF already on your computer, open the Scan Documents module's File menu and select the Open menu item. Browse to and select the TIFF image you intend to filter. Then, filter your Document as explained in the Filter Document section of this documentation.
When working with a TIFF from a CD, the file must be made writable after you copy it from the CD and before you attempt to filer it. To accomplish this on a Windows workstation, right-click on the TIFF file, select Properties, and uncheck the Read-only attribute.
Always compact your Document after applying a filter.
