Recognizing Arabic text with User Dictionary

I want to use a list of Arabic words to supplement the built in Arabic Dictionary

I performed these steps:

LoadEngine();

var languageDatabase = _engineLoader.Engine.CreateLanguageDatabase();

Dictionary dict = languageDatabase.OpenDictionaryExtension(LanguageIdEnum.LI_ArabicSaudiArabia);

dict.Edit(); // at this point, I imported a text file with 9,000,000 Arabic words, then exported it to

...\ABBYY SDK\11\FineReader Engine\Data\ExtendedDictionaries\Arabic.txt

string s = "x";

double i = 0;

while (s != null)

{

s = enumer.Next(out conf);

i++;

}

// at this point i was around 4.2 million - I assume that I successfully created a user dictionary

UnloadEngine();

Later, I then performed OCR:

LoadEngine()

var languageDatabase = _engineLoader.Engine.CreateLanguageDatabase();

Dictionary dict = languageDatabase.OpenDictionaryExtension(LanguageIdEnum.LI_ArabicSaudiArabia);

var document = _engineLoader.Engine.CreateFRDocument();

document.AddImageFile(imageFile);

var recognitionParameters = _engineLoader.Engine.CreateRecognizerParams();

recognitionParameters.SetPredefinedTextLanguage("Arabic");

var extractionParameters = _engineLoader.Engine.CreateObjectsExtractionParams();

extractionParameters.DetectTextOnPictures = true;

extractionParameters.RemoveGarbage = true;

extractionParameters.EnableAggressiveTextExtraction = true;

var documentParams = _engineLoader.Engine.CreateDocumentProcessingParams();

documentParams.PageProcessingParams.ObjectsExtractionParams = extractionParameters;

documentParams.PageProcessingParams.RecognizerParams = recognitionParameters;

document.Process(documentParams);

// and then go on to write results to PDF, RTF & XML

Have I performed the necessary steps needed to use the Standard and User Arabic dictionaries?

If not, what is missing

Thank you for your help
