Parameters

fileName

Name of the user dictionary file, must not be null (Nothing in Visual Basic).

defaultSectionName

Name of the default section in the user dictionary. If it is null (Nothing in Visual Basic), the default section will be the first section of the dictionary, if any.

Note: This parameter is not supported in the LEADTOOLS OCR Advantage Engine and it should be null.

A user dictionary typically consists of different sections, the sections may contain one or more specified items (IOcrUserDictionaryItem). You can enumerate the sections in the User dictionary with the GetFirstSectionName and GetNextSectionName methods.

Each zone can be linked to a section in the User dictionary using the OcrZone.UserDictionarySectionName property.

User dictionary items are strings and they must be no longer than MaximumItemLength characters. They may contain spaces and punctuation characters.

If there is no default section specified, in the methods that expects a defaultSectionName parameter, the first section of the User dictionary will be the default.

You can set the current user dictionary to use in the checking subsystem with the Use method. If no user dictionary has been set, no checking through the user dictionary will be performed.

You can use the Create method to create a new user dictionary and the Open method to open for edit an existing dictionary. You can then iterate through the sections and items as well as adding new sections and items to the dictionary. When you are done, you must call Save to save any changes you made to the dictionary and finally Close to close it.
