setting.A setting of

option, you can specify a precise level of confidence ranging from 0 to 100.The level value for

Medium

Spell check and Spell check flag
Select the
Spell check
option to have unrecognized words compared to entries in a dictionary of known
values. If they do not match, a spell check flag is inserted in front of the non-matching word. A default dictionary is used, based
on the currently selected language. You can also specify a custom dictionary by selecting a text file in the
Document Class Properties window
OCR tab.
Use the
Spell check flag
to specify a character to indicate words that are not found in a dictionary.
You can specify only a single character. Note that the following occurs when you have enabled and specified a spell check flag:
-
For a single language: All words are flagged when the selected language does not have a dictionary.
-
For multiple languages: Only words not found in the dictionary are flagged. If the selected language does not have a dictionary, then the word is not flagged.
If a word is flagged twice, once with the spell check flag and once with the confidence mark flag, the spell check flag is first, followed immediately by the confidence mark flag. However, if the two flags are set to the same character (for example ^), both flags are represented by a single character. This is the default behavior.
Character set
Use these settings to define the digit or character data filter.
A setting of
Any
means that the recognized data can contain any characters.
A setting of
Numbers only
means that the recognized data contains only digits.
A setting of
Letters only
means that the recognized data can contain only letters.
A setting of
Custom
means that you can add a set of characters to include to the recognition result. For
example, if the recognition zone includes dates in the format DD/MM/YYYY, enter digits and the "/" symbol in the custom filter
input field. In this case, the engine recognizes the date correctly.
