Training files are useful for recognizing characters that prove difficult
to recognize or are being regularly misrecognized. To create a training
file, see Training OCR on page 97.
Retain Graphics switch
Select Retain Graphics if you want OmniPage Pro to retain original
graphics, such as photographs or drawings, in the recognized
document. They will be displayed in Text view and exported to file,
provided the selected file format supports graphics. Graphics can be
exported by drag-and-drop, copying to Clipboard and Direct OCR.
Make sure that all the pictures you want retained are correctly
enclosed in zones with the zone type Graphic. These have black
borders and display a graphic icon. See Specifying zone types on
page 41.
If you deselect this, the contents of graphics zones are ignored.
Pictures will neither appear in Text view nor be available for export.
In the lower part of the panel you specify the resolution for graphics
exported in grayscale or color. Exported graphics appear as they do in
Text view (black-and-white, grayscale or color).
Reject Character
Words containing unrecognizable characters appear in red in the
Proofread OCR dialog box and optionally in Text view. Unrecognized
characters are replaced by a red reject character. The default character
is a tilde (~). Type the character you want to use in the Reject Character
edit box.
For example, if OmniPage Pro could not recognize the J in REJECT,
and the tilde (
~ ) was the reject character, the string RE ~ ECT would
appear in your recognized document.
Retain Graphics settings
Choose a resolution setting (75 or 150 dpi) to be used for the export
of grayscale or color image areas embedded in Text view. The settings
are applied when you save recognition results from the whole
document to file, send them to Clipboard or use Direct OCR.
