Defining the source of page imagesFigure
There are three possible image sources: from image files, from a digital camera and from a
scanner. There are two main types of scanners: flatbed or sheetfed. A scanner may have a
built-in or added Automatic Document Feeder (ADF), which makes it easier to scan multi-
page documents. The images from scanned documents can be input directly into OmniPage or
may be saved with the scanner’s own software to an image file, which OmniPage can later
open.
The minimum width or height for an image file is 16 by 16 pixels; the maximum is 8400
pixels (71cm or 28 inches at the resolution 201 to 600 dpi). See Help for pixel limits.
You can govern how PDF files are opened under Tools / Options / Process: open with the text
layer or as image, import tag information to assist layout retention and whether to use PDF
fonts or the mapped system fonts. See the eDiscovery Assistant for searchable PDF section
on how to make image-only PDF files searchable.
Input from image files
You can create image files from your own scanner, or receive them by e-mail or as fax files.
OmniPage can open a wide range of image file types. Select Load Files in the Get Pages drop-
down list. Files are specified in the Load Files dialog box. This appears when you start
automatic processing. In manual processing, click the Get Page button or use the Process
menu. The lower part of the dialog box provides advanced settings, and can be shown or
hidden.
